Ship the flag.
Not the ceremony.

Flagdeck is a feature-flag console for small teams: environments, percentage rollouts, allowlists, and a one-click promote button.

Everything a small team actually uses

One-click rollout

Copy staging onto production, or bump 0 → 5 → 25 → 100 without opening a ticket.

Percentage + allowlist

Hash users into consistent buckets. Keep VIPs and QA accounts always on.

Kill switch

Something on fire? Force every environment off in a single tap.

Evaluate API

A tiny HTTP endpoint your app can call. No SDK install required to try it.

Audit trail

Every enable, bump, and rollback is written to an activity feed.

Works offline in demo

State lives in your browser. Reset anytime. No account, no database.
