Bolt CMS

Bolt CMS is an open‑source, self‑hostable content management platform built on PHP, Symfony, Doctrine, Twig and API‑Platform. It can operate as a traditional CMS or in a headless/decoupled mode, exposing both RESTful and GraphQL endpoints out of the box. Configuration of page types, fields and languages is done through concise YAML files, and the system includes built‑in internationalisation with field‑level translation control.

The system targets developers, frontend designers and content creators who want a straightforward way to build modern multilingual websites. It ships with fully licensed Redactor and Article rich‑text editors, a dummy‑content generator for rapid prototyping, and extensibility via Symfony 5 extensions or Composer packages. Twig templates are used for rendering, allowing flexible and secure HTML generation.

Bolt is released under the MIT license, maintained as a stable 6.x series, and offers a free tier without subscription requirements. The project is actively maintained by a community of contributors and provides documentation for installation, development and contribution.
