FAQ

How do I integrate Feature Kill Switch into my app?
After signing up you get an API key. Add our lightweight SDK (one npm install) or call our REST endpoint directly. Flags are evaluated in real-time via Server-Sent Events.
What happens if the service goes down?
Our SDK defaults to the last known flag state cached locally, so your app keeps running. You can also set a hard-coded fallback per flag.
Can non-engineers really use this without help?
Yes. The dashboard is a simple list of toggles with names you define. No code, no terminal — just click to disable a feature instantly.
