EspoCRM

EspoCRM provides a web‑based customer‑relationship management platform that lets organizations store and organize leads, contacts, companies, projects, sales opportunities, marketing campaigns, and support cases. The interface is built as a single‑page application, offering a minimalist, fast UI that can be accessed through a browser, while a PHP‑backed REST API enables programmatic interaction and integration with other systems.

The software is self‑hostable and released under the AGPL‑3.0 license, allowing anyone to run it on‑premise without subscription fees. It supports PHP 8.3‑8.5 and works with MySQL, MariaDB, or PostgreSQL databases. Installation options include manual setup, scripted installers, Docker, and Traefik configurations, and the code follows SOLID principles with static typing and JSON‑schema‑driven metadata for extensibility.

Target users range from startups and small‑to‑medium businesses to larger enterprises that need a customizable CRM. Developers and tech enthusiasts can extend the platform by creating custom entities, fields, relationships, and extensions, while the open‑source nature provides transparency and community‑driven support.
