7 CRM systems you can run on your own server

A hosted CRM (customer relationship manager) keeps your leads, deals and notes in someone else's cloud. These seven store them in a database on your own server.

Every pick pushed a commit in the last 90 days (checked 2026-11-14), with an install path from its own repo or docs. Ordered by GitHub stars.

The 7 CRMs at a glance #

1. Twenty: the open alternative built for AI #

Twenty is an open-source CRM that calls itself "The open alternative to Salesforce, designed for AI."

What: A TypeScript CRM where objects, fields and views are defined as code, with workflows and AI agents included.

Why: The twenty CLI scaffolds apps on top of it, and the repo ships skills for coding agents.

Use when: You want a modern CRM your developers can extend like a platform.

Install:

bash <(curl -sL https://raw.githubusercontent.com/twentyhq/twenty/main/packages/twenty-docker/scripts/install.sh)

Catch: Mostly AGPL-3.0, but files marked Enterprise need a commercial license. The installer accepts only full release tags, not latest.

2. Odoo: CRM with an entire business behind it #

Odoo is "a suite of web based open source business apps", an open-source CRM among them.

What: A modular suite where CRM is one app beside accounting, inventory, eCommerce and HR.

Why: One deployment covers sales, stock and books.

Use when: You want CRM plus ERP (business management) in one system, and accept the suite's weight.

Install:

docker pull odoo

The image needs a running PostgreSQL server.

Catch: Two editions: Community (open source, LGPL-3.0) and Enterprise (licensed). Check which one a feature is in.

3. Monica: the personal CRM #

Monica is a "Personal CRM. Remember everything about your friends, family and business relationships."

What: Contacts, relationships, birthday reminders, notes and a diary about the people in your life.

Why: The only pick for a person, not a sales team. Its README headline is "Document your life".

Use when: You want to remember birthdays and conversations, not forecast a quarter.

Install:

docker pull monica

The image needs a MySQL or MariaDB database.

Catch: The repo's main branch is a beta. The stable version is the 4.x branch, which the Docker image ships.

4. Krayin: the CRM for Laravel shops #

Krayin is a "Free & Open Source CRM Built with Laravel for Customer, Lead, and Sales Management."

What: A CRM built on Laravel (a PHP framework) and Vue.js, with a modular design, custom attributes and an admin dashboard.

Why: If your team ships Laravel, this is a CRM your developers can read end to end.

Use when: You want MIT-licensed code and a stack your PHP team can customize.

Install:

composer create-project krayin/laravel-crm
php artisan krayin-crm:install

Set APP_URL, the database and mail in .env between the two commands.

Catch: You run the PHP stack yourself: PHP 8.3 or higher, 3 GB of RAM, MySQL or MariaDB.

5. SuiteCRM: the SugarCRM fork #

SuiteCRM is "Open source CRM for the world", a fork of SugarCRM built on its last open-source release.

What: An enterprise CRM on a LAMP stack (Apache, PHP, MySQL or MariaDB).

Why: It comes with an extensions directory, a partner network and vendor support plans.

Use when: You need an established enterprise CRM and already run LAMP servers.

Install: No one-line command. Download the release, unzip it into your web root and run the web installer, as in the installation guide.

Catch: This repo is SuiteCRM 7; SuiteCRM 8 lives in a separate repo and is, per the README, "not yet as feature complete".

6. Frappe CRM: sales on the Frappe Framework #

Frappe CRM is "a simple, affordable, open-source CRM tool designed for modern sales teams", built on the Frappe Framework.

What: Leads and deals on one page with activities, notes and tasks, a kanban board, custom views, and call and WhatsApp integrations.

Why: Three commands start it with Docker, and the site answers at crm.localhost:8000/crm.

Use when: You want a sales CRM without deploying all of ERPNext, Frappe's business suite.

Install:

wget -O docker-compose.yml https://raw.githubusercontent.com/frappe/crm/develop/docker/docker-compose.yml
wget -O init.sh https://raw.githubusercontent.com/frappe/crm/develop/docker/init.sh
docker compose up -d

Catch: This Docker setup pulls the unstable develop branch; production uses the easy-install.py script. Change the default login (Administrator / admin) first.

7. EspoCRM: the classic CRM with a clean interface #

EspoCRM is "a free, open-source CRM platform designed to help organizations build and maintain strong customer relationships".

What: Leads, contacts, opportunities, campaigns and support cases in a single-page app with a PHP REST API backend.

Why: The README promises "an uncluttered, minimalist, and fast user interface".

Use when: You want standard CRM done plainly, without a suite around it.

Install:

docker pull espocrm/espocrm

The docs' quick start runs it beside a MariaDB container.

Catch: Reports, workflows and business process management come in the Advanced Pack, an official add-on, not in the core.
