Strapi
The established open headless CMS, with the largest community.
Strapi is the most widely deployed open-source headless CMS: a content-type builder, REST and GraphQL APIs, role-based permissions, internationalisation and a large plugin marketplace. Around 73k stars. It is the safe choice in the sense that most problems you hit have already been asked about somewhere. Licensing is mixed and worth checking against your needs: the core is MIT, but a number of enterprise features — SSO, audit logs, advanced permissions — sit under a separate commercial licence.
What it does well
- +Largest community and plugin ecosystem of any open headless CMS
- +Content-type builder that non-developers can use
- +REST and GraphQL out of the box
- +Mature, with years of production deployments
Where it falls short
- −SSO, audit logs and advanced permissions are commercial
- −Major version upgrades have been disruptive historically
- −Heavier to run than Payload
- −Single-vendor governance
