Feature flags & experiments

Release to who you choose. Prove what works.

Feature flags, remote config and A/B tests on the same key you already use for guides and analytics, in browsers, mobile apps and on your servers.

Flags and remote config
Boolean, string, number or JSON values, each with its own rules in Development, Staging and Production.
Release to who you choose
Target by any attribute, segment or other flag, release to a percentage of users, and ramp it up on a schedule.
A/B tests with real results
Experiments record who saw which variation and compare your goal events: uplift, intervals, chance to win and a sample-ratio check. Stop with a winner and it rolls out.
A kill switch that's always instant
Turning a flag off takes effect straight away, even where changes need approval. Every change is a revision you can revert.
Fast, and the same everywhere
SDKs evaluate locally from one cached payload, keep working offline and pick up changes in seconds. Web, iOS, Android, Node, PHP and Java all give a user the same value.
Coming from ConfigCat?
Import your flags, targeting rules and segments, mapped onto your environments, and preview everything before it's written.
