A release system, not a toggle collection.

FlagDash covers the full path from first internal exposure to safe rollout and final code removal.

01 Audience

Target precisely

Context rules, reusable segments, individual users, and consistent bucketing.

Targeting guide

02 Evidence

Advance with evidence

Progressive steps wait for external health signals before adding traffic.

Release guide

03 Guardrail

Pause or roll back

Missing data pauses safely. Failing data can restore starting traffic.

04 Cleanup

Finish the cleanup

Lifecycle ownership and repository scans keep temporary flags temporary.

Cleanup guide

One control plane. Every runtime decision.

Keep release logic, live settings, experiments, and agent instructions together without coupling their lifecycles.

Explore all guides

Feature flags and experiments

Typed values with targeting, variations, schedules, guarded releases, and rollouts.

SegmentsA/B testsSchedules

Remote config

Typed settings that change by environment without an application deploy.

Realtime updates

SSE pushes changes immediately, with polling fallback when connections drop.

Remote translations

Draft localized copy, inspect fallback, then publish one environment release.

AI configs and skills

Version agent instructions by environment. Discover descriptions first and load full skill bodies only when needed.

Resilience by architecture

Flag reads stay up.
Everything else can recover.

Evaluation is isolated from analytics, billing, webhooks, schedules, and integrations.
