Capabilities

What feature flags gives you

Feature flags, staged rollouts, and experiment assignment.

No flash of the default value
Flags resolve before first paint rather than after hydration, so users do not see the control variant blink into the treatment — the failure mode that quietly invalidates an experiment and looks like a visual bug.
- Resolves before paint
- No flicker
Rollouts and experiments on one assignment
Staged percentage rollouts and experiment variants come from the same evaluation, with exposures recorded when a flag is actually read — so analysis counts users who saw the variant, not everyone who loaded the page.
- Staged rollouts
- Exposure tracking
Remote config, and overrides for QA
Ship values, not just booleans, and refresh them without a release. Local overrides let QA pin a variant on a device without touching the rollout everyone else is on.
- Remote config
- QA overrides
- Refresh without release
