Live in production

Why foff

Built for teams that
move fast

Three principles shape every product decision we make.

Decouple Deploys from Releases

Ship safely on every release cycle. Separate deployment from exposure, then roll out deliberately with full control.

Safe production rollouts

Scale Control with Confidence

Manage targeting across scopes, ship gradual releases, and recover instantly when production needs a fast fallback.

Granular targeting

Perform A/B Testing

Test variants against real traffic, compare outcomes quickly, and promote the version that performs best.

Data-backed decisions
