Nona
Self-hosted remote config and feature flags — one Docker command, REST API for any language
Nona is an open-source (Apache 2.0) remote config and feature-flag service you run yourself with one Docker command, with native JavaScript and .NET clients plus OpenFeature provider support. It covers kill switches, multi-environment config isolated by API key, config releases, and shareable no-login parameter links — but stops there. Nona says outright that Firebase Remote Config is the better fit if you want a vendor-operated, globally managed service instead of something you self-host and inspect.
What holds up
- +Apache 2.0 and self-hostable — one Docker command, no vendor account required
- +REST API works from any language with no SDK — one GET request returns all config as JSON
- +Says directly that Firebase is the better choice if a managed global service is the priority
Mind the limits
- −Self-hosted only — no managed global infrastructure, which the comparison table credits to Firebase
- −Only JavaScript and .NET have native clients — other languages call the REST API directly
