A free self-hosted CRM can remove per-user software fees and give your business direct control over customer data.

It does not remove the cost of the VPS, backups, security, email delivery, upgrades or the person responsible for keeping the system available.

That trade-off is worthwhile when you need custom fields, integrations, data-location control or a CRM that can grow without a monthly fee for every user.

It is a poor bargain when nobody on the team can maintain a production server.

I reviewed the current official product, licensing, installation and release documentation for seven actively maintained CRM projects.

This guide ranks them by practical VPS fit, core CRM usefulness, free-edition clarity and the amount of administration they require.

The short answer: EspoCRM is the best starting point for most VPS users

EspoCRM takes the top position because its core CRM covers the work most small and medium sales teams need while retaining a relatively familiar PHP and database stack.

SuiteCRM is stronger when the business needs a broader, more mature CRM footprint.

Twenty is the most attractive option here for teams that value a modern interface, custom data models and Docker-first deployment.

The best choice still depends on what happens after a deal is won:

• Choose EspoCRM for a focused, adaptable sales CRM.

• Choose SuiteCRM for mature sales, marketing and service processes.

• Choose Twenty for a modern interface, custom objects and workflows.

• Choose Frappe CRM for a clean pipeline that can connect to ERPNext.

• Choose Odoo Community for a modular business-app ecosystem.

• Choose ERPNext when CRM must connect directly to accounting, stock and operations.

• Choose Dolibarr for a modular small-business ERP and CRM with a traditional PHP stack.

Every option below can run on your own server. Review our CRM hosting in Kenya guide first if you need help deciding whether self-hosting, shared hosting, a VPS or vendor-hosted software is the right operating model.

How the seven free self-hosted CRMs compare

The sizing column contains editorial starting points for a small production deployment with the application and database on one Linux VPS.

They are not vendor minimums or performance guarantees.

Test with your expected users, imports, email activity, reports, attachments and integrations before committing.

Rank	CRM	Best fit	Free software license	Official deployment route	Small production VPS starting point to test
1	EspoCRM	Focused sales and customer management	AGPLv3	Package, installer script or Docker	2 vCPU and 4 GB RAM
2	SuiteCRM	Mature sales, marketing and service workflows	AGPLv3	Package installation on a supported PHP stack	2 vCPU and 4 GB RAM
3	Twenty	Modern, highly configurable CRM	AGPLv3 core with paid premium features	Docker Compose	2 vCPU and 4 GB RAM
4	Frappe CRM	Modern pipeline and Frappe ecosystem	AGPLv3	Production install script or Docker	2 vCPU and 4 GB RAM
5	Odoo Community	CRM plus modular business applications	LGPLv3	Packages, source or official Docker base image	2 to 4 vCPU and 4 to 8 GB RAM
6	ERPNext	CRM connected to accounting, sales and inventory	GPLv3	Frappe Docker or Bench	4 vCPU and 8 GB RAM
7	Dolibarr	Small-business ERP and CRM	GPLv3 or later	Web package, platform installers or Docker	2 vCPU and 2 to 4 GB RAM

For most small production deployments, 4 GB RAM is a safer test point than 2 GB because the operating system, database, web server, background jobs, security tools and backup process all need memory.

ERP-style products deserve more headroom.

Truehost VPS hosting offers Linux servers with root access plus managed and unmanaged options.

Choose the CRM first, then match the server to its documented stack and your busiest expected workload.

What free means in this comparison

Every product on this list has a self-hostable edition whose source is distributed under an open-source license.

That lets you run the covered software without paying a normal per-user subscription fee.

Free does not necessarily include:

• premium extensions or enterprise modules;

• implementation and data migration;

• vendor support;

• a domain name, VPS or backup storage;

• transactional email, telephony or messaging services;

• server monitoring and incident response;

• major-version upgrade work; or

• custom development.

License terms also matter if you modify the software or provide it as a network service. AGPL, GPL and LGPL impose different obligations.

This article identifies the published license but does not replace legal advice for redistribution, modification or commercial hosting.

How I ranked the CRM platforms

The ranking gives more weight to deployment practicality than to the length of a feature list. Each CRM was checked for:

• a current official self-hosting path;

• an identifiable free-software license;

• leads, contacts, organisations or accounts, and deal or opportunity tracking;

• current documentation and recent project activity;

• a stack that can run sensibly on a VPS;

• clarity about features outside the free edition; and

• an upgrade and backup path a small technical team can realistically own.

I did not conduct a production load test or a full implementation of all seven systems.

The ranking is a source-backed desk assessment. Test the finalists with your real data and workflows before migrating the sales team.

1) EspoCRM: best overall free CRM for a straightforward VPS deployment

EspoCRM is the strongest general recommendation for a small or medium team that wants a dedicated CRM rather than an entire ERP platform.

Its free core handles leads, opportunities, accounts, contacts, calendars, email, cases, campaigns, documents and configurable entities.

The official EspoCRM feature overview also shows web-to-lead capture, import and export, customer-support tools and administration features. The interface can be adapted with custom entities, fields, relationships, layouts and dynamic field logic.

Why EspoCRM ranks first

Its deployment choices are practical. The standard installation guide supports PHP with MySQL, MariaDB or PostgreSQL. EspoCRM also publishes an official Docker installation path and an installer script that assembles Nginx, MariaDB and the application.

The project is distributed under AGPLv3. Its official repository showed version 9.3.7 as the latest release during this review, dated May 2026.

What the free edition does not include

Do not assume every item on the broad features page belongs to the free core. EspoCRM documents reporting, workflow automation and business-process management as part of its paid Advanced Pack. Product, quotation, order and invoicing functions also belong to commercial extensions.

The free core remains capable for relationship and pipeline management. A team that needs advanced reports or visual automation should include extension costs in the comparison.

VPS deployment notes

Start testing a small production instance at 2 vCPU and 4 GB RAM. Configure the web root correctly, run scheduled jobs under the web-server user, enable HTTPS and keep uploaded files and the database in the backup plan.

EspoCRM is the best fit here when you want a focused CRM, a familiar web stack and enough no-code customisation to match a normal sales process without deploying an ERP.

2) SuiteCRM: best for mature sales, marketing and service processes

SuiteCRM has the broadest traditional CRM footprint in this list. It suits organisations that need leads, opportunities, accounts, contacts, campaigns, cases, reports, workflows and detailed role-based administration in one free platform.

SuiteCRM states that its code remains free and open source, and the project is governed by AGPLv3. Its current download page offers both the long-running SuiteCRM 7 line and the newer SuiteCRM 8 line.

Why SuiteCRM ranks second

SuiteCRM has a mature data model and a large body of documentation. Version 8.10.1 was the current maintenance release during this review. The SuiteCRM 8.10 compatibility matrix supports PHP 8.2 through 8.4, Apache 2.4, and listed MySQL or MariaDB versions.

The platform is attractive when the CRM must support multiple departments or a more formal implementation. It also gives administrators a Studio interface for adapting fields, layouts and modules.

The main trade-off

Breadth creates complexity. SuiteCRM needs more planning than a minimal contact-and-pipeline tool. Schedulers must run reliably, email needs careful configuration, permissions require testing and upgrades should be rehearsed on a staging copy.

SuiteCRM 8 is also still carrying forward and modernising parts of the SuiteCRM 7 platform. Read the release and migration notes for the exact version you install instead of assuming every older module behaves identically in the newer interface.

VPS deployment notes

A 2 vCPU, 4 GB RAM server is a sensible starting point to test for a small team. Increase memory for large imports, many concurrent users, heavy reporting, campaigns or custom modules.

Choose SuiteCRM when functional depth matters more than having the lightest installation. Keep it patched because CRM releases often contain important security corrections as well as features.

3) Twenty: best modern Docker-first self-hosted CRM

Twenty offers the cleanest modern product direction in this comparison. It provides people, companies, opportunities, tasks, notes, files, email and calendar integration, custom objects, custom fields, saved views, dashboards and workflows.

The official key-features guide describes table, Kanban and calendar views plus a configurable data model. This makes Twenty useful when a team wants to shape the CRM around its own objects instead of accepting a fixed legacy schema.

Why Twenty ranks third

Self-hosting is a first-class deployment route. The Docker Compose guide provides a one-line installer and manual Compose workflow. It states a minimum of 2 GB RAM and recommends a reverse proxy with HTTPS for a public domain.

The core repository is licensed under AGPLv3. Twenty was also shipping releases frequently during this review, with version 2.8.0 published in May 2026.

Understand the free-plan boundary

Twenty’s official pricing documentation says the free self-hosted plan includes the Pro feature set, email and calendar sync, workflows, community support and control of your data.

Premium self-hosted features include SSO, row-level permissions and AI usage data. This distinction matters for larger organisations. Basic roles and field permissions are not the same as restricting individual records by territory, branch or owner.

VPS deployment notes

Do not treat the official 2 GB requirement as an ideal production size. Start at 4 GB for a normal team so the application, database, worker processes and upgrades have room. Pin a known version, read each upgrade note and back up persistent volumes before updating.

Choose Twenty when user experience, custom data models and no-code workflows are more important than the long history of a traditional CRM suite.

4) Frappe CRM: best modern CRM for teams entering the Frappe ecosystem

Frappe CRM is a sales-focused application built on the Frappe Framework. It manages leads, deals, organisations, contacts and activity while keeping the interface narrower than ERPNext.

Its official documentation supports list and Kanban views, configurable deal stages, email from lead and deal records, calls, tasks, notes, attachments, forecasting and custom fields. A won deal can later connect to ERPNext when the business needs quotations, accounting or inventory.

Why Frappe CRM makes the list

Frappe CRM is licensed under AGPLv3 and has a current official self-hosting path. The production installation guide offers an easy-install script using the stable container image. Docker and Bench routes are also documented.

The project was actively releasing during this review. Its repository listed version 1.72.0 in May 2026.

The main trade-off

The application is simpler than ERPNext, but the underlying Frappe stack still has multiple services and its own operational conventions. The vendor explicitly recommends considering Frappe Cloud before self-hosting.

That recommendation is reasonable for a team without Linux and container experience. Self-hosting gives control, but your team owns upgrades, queues, email configuration, database health and recovery.

VPS deployment notes

Test a small deployment at 2 vCPU and 4 GB RAM. Use the stable production image, not the development Compose files, for a live business system. Change default credentials immediately, configure the site hostname and DNS correctly, and store recoverable backups away from the VPS.

Choose Frappe CRM when you want a modern sales application today and a credible route into the broader Frappe or ERPNext environment later.

5) Odoo Community: best modular CRM and business-app ecosystem

Odoo Community is the free, open-source foundation of the Odoo platform. The CRM application supports leads, opportunities, sales teams, stages, activities and pipeline management. Other Community modules can extend the same database into sales, websites, inventory and additional business processes.

Odoo 19 Community is licensed under LGPLv3. Its on-premise documentation provides packaged, source and Docker-based installation routes.

Why Odoo Community ranks fifth

The main advantage is modularity. A business can begin with CRM and install other compatible applications as needs grow. Odoo also has a large developer and implementation ecosystem.

Its production documentation is unusually detailed about reverse proxies, PostgreSQL, workers, database filters, HTTPS, database-manager security and off-server backups. That is useful because a public Odoo deployment needs deliberate hardening.

The main trade-off

Odoo Community and Odoo Enterprise are not the same product bundle. Enterprise code requires a subscription, and applications from the Odoo Apps marketplace can use LGPL, proprietary or other licences. Confirm the edition and licence of every module before promising a feature.

Custom modules also increase upgrade work. A heavily customised Odoo database is a business application project, not a simple one-click CRM installation.

VPS deployment notes

Start a small test at 2 vCPU and 4 GB RAM. Use 4 vCPU and 8 GB RAM when several applications, workers, scheduled jobs or active users share the instance. Odoo’s worker sizing should follow measured concurrency and memory use, not a generic ratio copied from another deployment.

Choose Odoo Community when CRM is the first of several connected business applications and the organisation can support a more formal implementation.

6) ERPNext: best when CRM must connect to operations and accounting

ERPNext is an open-source ERP system that includes CRM rather than a CRM with a few accounting add-ons. Its sales pipeline connects leads and opportunities to quotations, customers, orders, invoices, stock, projects and accounting records.

The ERPNext opportunity documentation covers follow-up dates, assignment rules, opportunity values, products, quotations and lost-reason tracking. CRM reports include a sales funnel, lead details, inactive customers and first-response measurements.

Why ERPNext ranks sixth

ERPNext becomes compelling when closing a deal should trigger the rest of the business process in the same platform. It is licensed under GPLv3 and has an active official repository. The repository listed version 16.22.0 in June 2026.

The official self-hosting routes use Frappe Docker or Bench. Docker requires Docker Compose and Git, while a production deployment adds MariaDB, workers, queues, scheduled jobs and file storage to the operating picture.

The main trade-off

ERPNext is excessive when the business only needs contacts and a pipeline. More modules create more configuration, permissions, training, upgrade testing and backup responsibility.

Select it because the company needs an ERP workflow, not because the word free makes it appear cheaper than a dedicated CRM.

VPS deployment notes

Begin production testing around 4 vCPU and 8 GB RAM for a small integrated deployment. Larger databases, many workers, manufacturing, stock operations, reports or concurrent users require measured sizing beyond that starting point.

Choose ERPNext when sales, purchasing, inventory, projects and finance should share one record system and the team can operate the Frappe stack reliably.

7) Dolibarr: best modular ERP and CRM for a small business

Dolibarr combines CRM and ERP functions in a PHP web application. Businesses can enable only the modules they need, including prospects, customers, opportunities, proposals, sales orders, contracts, invoices, projects, stock and help-desk tickets.

The official Dolibarr site supports installation on a local machine, dedicated server, virtual machine or Docker environment. The project is distributed under GPLv3 or later.

Why Dolibarr belongs in the top seven

Dolibarr is useful for a smaller business that wants customer management and commercial documents without adopting the broader architecture of ERPNext or Odoo. Its conventional PHP deployment can also be easier for administrators already comfortable with Nginx or Apache and a MySQL-compatible database.

The project remains active. Its official repository listed Dolibarr 23.0.3 in May 2026 during this review.

The main trade-off

Dolibarr is organised as a broad set of business modules. A team seeking a highly polished sales-only workspace may prefer EspoCRM, Twenty or Frappe CRM. Test the exact lead, pipeline, email and permission flow before assuming that an ERP module matches how the sales team works.

External modules can also have their own licences, maintenance schedules and compatibility requirements.

VPS deployment notes

A small deployment can begin testing at 2 vCPU and 2 to 4 GB RAM. Allocate more memory for many enabled modules, documents, scheduled jobs or concurrent users.

Choose Dolibarr when the company needs a practical mix of customer records, proposals, orders and invoicing in one modular PHP application.

Choose the CRM from the job it must perform

Use this decision guide before comparing server prices:

Your main requirement	Best starting candidate	Why
A focused sales CRM with a familiar stack	EspoCRM	Strong free core and flexible PHP deployment
Mature cross-department CRM processes	SuiteCRM	Broad sales, marketing and service functionality
Modern interface and custom data model	Twenty	Docker-first platform with custom objects and workflows
Modern pipeline with a path to ERPNext	Frappe CRM	Focused CRM built on the Frappe ecosystem
CRM plus a large modular app ecosystem	Odoo Community	CRM can share one platform with other business applications
Sales connected to accounting and inventory	ERPNext	Full ERP workflow from opportunity to operations
Small-business CRM, proposals and invoicing	Dolibarr	Modular ERP and CRM on a conventional PHP stack

Create a small test instance of the top two candidates. Import representative records, not the entire production database. Ask real users to create a lead, qualify it, schedule a follow-up, send an email, move a deal, produce a report and find the customer history.

The better CRM is the one your team can use correctly and your administrator can recover after a failure.

Size the VPS for the whole CRM stack

Do not size from the CRM name alone. Estimate:

• active users at the busiest hour;

• database size and monthly growth;

• email sync and sending volume;

• attachment and document storage;

• number and frequency of background jobs;

• report, import and export workload;

• integrations, webhooks and API traffic;

• monitoring and security tools; and

• temporary space required for upgrades and backups.

A 4 GB server is a practical test point for most dedicated CRM products in this list. It is not a guarantee. ERP platforms, high concurrency, large databases and heavy automation can require 8 GB or more.

Use our guide to estimating VPS RAM to build a workload estimate. Select a plan that can add CPU, memory and storage without rebuilding the CRM from scratch.

Deploy the selected CRM in ten controlled stages

1. Choose the exact CRM edition and stable version.

2. Confirm its supported operating system, runtime, database and web-server versions.

3. Decide whether the VPS will be managed or unmanaged. Our managed versus unmanaged VPS guide explains the responsibility boundary.

4. Create a dedicated hostname such as crm.example.co.ke and point its DNS record to the server.

5. Patch the operating system, create a non-root administrator, use SSH keys and restrict the firewall.

6. Install the CRM through its current official production method. Do not use a development or disposable-demo setup for customer data.

7. Enable HTTPS and replace every default password, secret and example credential.

8. Configure scheduled jobs, queues, email and storage, then confirm that background work completes.

9. Back up the database, configuration, uploaded files and encryption secrets to storage outside the VPS. Follow a repeatable automated hosting backup plan.

10. Test lead creation, permissions, email, imports, exports, integrations and a full restore before inviting the team.

Add uptime, memory, CPU, disk and job-failure alerts using the checks in our VPS monitoring guide. A CRM backup is not proven until someone restores it successfully.

Managed or unmanaged VPS for a self-hosted CRM?

Choose an unmanaged VPS when your team can administer Linux, containers or the required runtime, database security, monitoring, patching, backups and incident recovery.

Choose a managed service when you need help operating the server layer. Read the scope carefully. A managed VPS may cover the operating system, firewall, control panel and backups without managing CRM configuration, custom modules, data imports or application upgrades.

Write down who owns each layer before deployment:

Responsibility	CRM administrator	Server administrator	Hosting provider
Sales stages, fields and user roles	Usually	Rarely	No
CRM application updates and extensions	Depends on agreement	Often	Only if included
Linux security and service health	Rarely	Yes	Only within management scope
Database and file backups	Verify	Configure and test	Only if included
Data migration and cleanup	Yes	Supports technically	No
Recovery after a failed update	Shares responsibility	Yes	Only within management scope

Do not buy the word managed without an explicit task list and escalation path.

Free Self-Hosted CRM FAQs

Are self-hosted CRMs really free?

The software editions in this list can be self-hosted without a normal per-user licence fee. You still pay for the VPS, backup storage, email services, implementation, maintenance and staff time. Some products also sell premium extensions, enterprise permissions or support.

What is the best free self-hosted CRM for a small business?

EspoCRM is the best general starting point for a small business that wants a focused CRM and a familiar PHP stack. Twenty is attractive for a modern, configurable interface, while Dolibarr is better when proposals, orders and invoicing should sit beside customer records.

How much RAM does a self-hosted CRM need?

Four gigabytes is a practical starting point to test many small production CRM deployments. A lightweight PHP installation may use less, while ERPNext, Odoo, large databases, many users and heavy background jobs may need 8 GB or more. Measure the real workload before final sizing.

Should I install a CRM with Docker?

Use Docker when the CRM publishes and maintains a production container workflow your team understands. Containers can make dependencies and rollback planning clearer, but they do not remove the need to manage persistent data, secrets, HTTPS, updates, monitoring and backups.

Can I run several CRMs on one VPS?

It is technically possible, but separate production CRMs compete for CPU, memory, storage and network resources. They can also share a failure domain. Use isolation, resource limits, separate databases and tested backups, or choose separate VPS instances when the systems hold important customer data.

Which CRM is best if I also need accounting and inventory?

ERPNext is the strongest choice here when CRM must connect directly to quotations, orders, accounting and stock. Odoo Community and Dolibarr are also suitable modular options. Test local accounting, tax and reporting requirements before making any ERP the financial system of record.

Should I use a managed or unmanaged VPS for CRM hosting?

Use an unmanaged VPS only when your team can secure Linux, maintain the CRM stack, monitor services and restore backups. Choose managed hosting when you need server help, but confirm whether CRM updates, database recovery and application troubleshooting are included.

Compare Truehost VPS plans

Pick the CRM first, then deploy the right VPS

EspoCRM is the strongest first trial for most small and medium teams. SuiteCRM is better when mature CRM depth matters. Twenty and Frappe CRM provide more modern sales experiences, while Odoo Community, ERPNext and Dolibarr make sense when customer management must connect to broader business operations.

Shortlist two products and test the work your team performs every day. Confirm the free-edition boundary, supported stack, upgrade path and backup process before importing customer data.

Compare Truehost VPS plans after choosing the CRM, then size the server from the documented stack and your expected workload. Select managed support if your team does not want to own the server layer.
