Featureflip runs on your own machine — the client starts it, so there is no endpoint to ping. 350 installs a week from npm. Last commit 16 Sep 2026.
Manage Featureflip feature flags, targeting and rollouts from AI agents and editors.
Today is the operative word: we check Featureflip every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
FEATUREFLIP_TOKEN (Featureflip API token. A personal token (ffp_) acts as you; a service token (ffs_) is a scoped machine identity for CI and agents.), FEATUREFLIP_API_URL (Management API base URL. Defaults to https://api.featureflip.io.), FEATUREFLIP_ORG (Organization slug. Only needed for a personal token that can reach more than one organization.).
The author declared them in the registry entry; get the values from the project itself.
