FireCMS is an open-source framework that serves as both a Firebase GUI and a headless CMS. It gives developers a visual interface to manage Firestore data, build admin panels, and ship back-office applications quickly. It solves the problem of manually interacting with Firebase via the console or writing custom admin UIs from scratch.
FireCMS is built for developers, startups, and agencies. Startups can launch MVP back-offices in minutes. Agencies can deliver custom admin panels for clients with zero infrastructure management. It is not designed for non-technical content editors who need a WYSIWYG-only experience without any developer setup.
Use FireCMS as a Firestore CMS to power blogs and marketing sites with a Notion-style editor. Build internal tools for support and operations teams. Create custom data-intensive admin panels with full control over views and business logic. FireCMS supports both cloud-hosted and self-hosted deployments.
