EspoCRM

EspoCRM needs PHP 8.3 to 8.5 with the usual extensions (PDO, mbstring, GD, curl, zip, xml), and one of MySQL 8.0+, MariaDB 10.6+, or PostgreSQL 15+. It runs behind Apache, Nginx, or IIS, and an official Docker installation is documented if you prefer containers.

Users log in with local accounts, and administrators can require two-factor authentication via TOTP (authenticator apps), email codes, or SMS through an SMS provider extension. OpenID Connect and LDAP authorization (including Active Directory and OpenLDAP) are supported for single sign-on, and roles control what each user can access.

Yes. The built-in import tool takes UTF-8 CSV files and supports Create Only, Create & Update, and Update Only modes, with field mapping and matching on chosen fields to avoid duplicates. Newly created records can be reverted if something goes wrong, and large imports can run in idle via cron or from the console.

EspoCRM exposes a REST API covering CRUD operations and related records, with official client libraries for PHP, JavaScript, Python, Rust, Java, Go, and Zig. Outgoing webhooks can be configured for entity events, and incoming web-to-lead and API endpoints let external forms and services push data in.

The Entity Manager lets administrators create custom entities, fields, and relationships, while the Layout Manager controls forms, list views, and detail pages. Dynamic Logic and formula scripts handle conditional behaviour and calculated values without code, and PHP or JavaScript extensions cover deeper changes when you need them.
