The best self-hosted CRM in 2026

At a glance

Checked on 8 November 2026 from each project's licence file, release tags and official pricing pages.

Odoo CRM

Best for: teams that want CRM tightly linked to sales, invoicing and inventory in one suite.

Watch for: Self-hosting the Enterprise edition requires the Custom plan, a recurring per-user subscription; the free LGPL Community edition omits Enterprise-only apps (for example the 20.0 Community repo has no helpdesk or knowledge module). [2]

India: Odoo Community ships India accounting localisation (l10n_in), plus e-invoicing (l10n_in_edi) and e-way bill (l10n_in_ewaybill) modules that submit to the government via a GSP. These sit in Invoicing/Accounting rather than CRM itself. [16]

Frappe CRM

Best for: small and mid-sized sales teams that want a modern lead and deal pipeline, optionally linked to ERPNext.

Watch for: Frappe's own docs say that if you need a highly complex enterprise CRM with deep out-of-the-box integrations, Frappe CRM might feel lightweight. [17]

India: No India-specific CRM features documented. It integrates with ERPNext, where the separate India Compliance app adds GST, e-invoice and e-way bill. [17]

SuiteCRM

Best for: organisations that want a mature, Salesforce-style CRM with no per-user licence fee.

Watch for: Two product lines (7.x and 8.x) are still released in parallel, so teams must check which line their add-ons and customisations target. [9]

EspoCRM

Best for: small and mid-sized businesses that want a light, fast, highly configurable CRM.

Watch for: Reports, Workflows and BPM are in the paid Advanced Pack extension, not the free core. [18]

Twenty

Best for: product-minded teams that want a modern, developer-friendly CRM they can extend with code.

Watch for: SSO, row-level permissions and audit logs are premium features that need an Organization plan, including when self-hosted. [19]

How to choose

• If you also need invoicing, inventory and accounting, pick a suite (Odoo or Frappe CRM with ERPNext) rather than a standalone CRM.
• If you need SSO, audit logs or row-level permissions, check whether they are in the free edition; in Twenty they need the Organization plan.
• If your team has no developers, budget for paid hosting or support; every option here is free to run but not free to operate.

Where OwnCRM fits

OwnCRM is a commercial product, not open source. It is sold as a perpetual licence or a managed subscription, with no per-seat pricing, and runs on-premise, in your private cloud or air-gapped. Its difference from the options above is scope: pipeline, forecasting and campaigns share one model with ERP, HRMS, finance and helpdesk across 23 OwnApps, with governed AI agents working across them.

Choose an open-source option above if you want no licence cost and have the team to run it. Choose Own360 if you want one supported product across functions, bought outright, on your own infrastructure.

Questions buyers ask

What is the best self-hosted CRM?

For a free, mature CRM you run yourself, SuiteCRM and EspoCRM are the most established, Frappe CRM and Twenty are the most modern, and Odoo suits teams that want CRM inside a full ERP. Watch which features sit behind paid editions: reports and workflows in EspoCRM, and SSO and audit logs in Twenty.

Are these options really free?

The software in the open-source editions is free to run, but hosting, upgrades and support are not, and several projects keep features such as SSO, payroll or reporting in paid editions. Check each Watch for note above.

Is Own360 open source?

No. OwnCRM is a commercial product sold as a perpetual licence or a managed subscription, deployed on your own infrastructure.
