Flagsmith
Open-source feature flag and remote config platform, available self-hosted or as a cloud service, with SDKs for web, mobile and server-side apps.

Flagsmith manages feature flags and remote config for web, mobile and server-side apps. Its server is a Python API built with Django and the Django REST Framework, a web dashboard written in Node.js and React talks to it over REST, and PostgreSQL stores the data. Besides self-hosting, the docs describe a cloud service and a private cloud deployment.
Worth knowing
A self-hosted instance keeps the API, the dashboard and the database running, so it needs a host that runs processes; the Docker guide sets them up with Docker Compose. Enterprise Edition requires a Flagsmith Enterprise license, and the core functionality is open source.
