Feature flags stopped being about flags.
They became a pricing negotiation.

Flagline is gradual rollout + feature flags with unlimited seats under a data-volume cap. No per-seat ransom, no SSO paywall to talk to your own teammates.

Free tier, then $25/month flat — unlimited seats. Founding members lock this in forever.

flagline — gradual rollout demo

100 simulated users, hashed consistently — the same user always gets the same result at a given rollout %, exactly like the real evaluator.

Why this exists

Every incumbent's free tier caps you at 1-3 seats, then makes SSO and audit logs an enterprise-only paywall. Small teams don't have an enterprise budget — they have five engineers who all need to see the same flags. This is the positioning we're testing before writing a line of backend code: is that pricing anger real and vocal, or a paper tiger?
