Product features
The capabilities that make up Featureflip. Each one is evaluated locally in sub-milliseconds and changes from the dashboard without a redeploy. Explore how each works in depth.
Percentage rollouts
Ramp a feature from 1% to 100% of users on a slider. The percentage is a dashboard setting, not a redeploy, and deterministic sticky bucketing keeps each user in place as you climb.
Sticky bucketing · sub-ms local eval · live over SSE

Feature flag targeting
Serve a variation to the users who match an attribute rule and the default to everyone else. Combine conditions with AND and OR, reuse a segment across flags, and change who is targeted from the dashboard.
Attribute rules · reusable segments · per-environment

Environments
Keep development, staging, and production fully isolated. Each environment has its own SDK key and its own flag states, targeting rules, and rollout percentages, so a feature is on in one and off in another with only the key telling your deployments apart.
A key per environment · isolated config · promote without a redeploy

Scheduled changes
Queue a flag to turn on or off automatically at a future time and let Featureflip flip it for you. No cron jobs, no CI wiring, no one awake for the cutover — the change applies server-side, streams to your SDKs live, and is recorded in the audit log under your name.

SDKs
Official libraries for 13 languages and frameworks. Server SDKs evaluate flags locally in sub-milliseconds, every SDK streams live updates over SSE, and the same flag returns the same answer on every platform.
13 SDKs · local eval · one consistent API

Audit log
Every change to a flag, recorded automatically: who made it, what moved from and to, and when. Read it organization-wide with filters or per flag on a History tab, with retention from 7 to 365 days.
Automatic · before-and-after values · filterable

REST API
Everything the dashboard does, over HTTP. Create flags from CI, toggle them from a deploy script, and build internal tooling on the same configuration your team edits, with idempotent creates and rate-limit headers on every response.
Full management surface · token auth · included on every plan
