Compare all features

LaunchDarkly

Unleash

Unified platform for flagging, testing, and governance

Core flagging platform; experimentation offered as an add-on, not fully integrated

42T+ daily flag evals, sub‑200 ms latency, global edge delivery

Built for smaller-scale delivery; SDKs poll every 15 s and no public edge SLA is documented

Automated rollbacks from metric or observability signals

No built-in integration for observability-based rollbacks; toggles are manual.

Multi‑context targeting (e.g. device, team, env, account)

Supports context constraints but no documented multi-context or chained targeting.

35+ SDKs across mobile, edge, and server

Broad SDK and Edge support

Audit logs, approval policies, and environment diffing

Enterprise includes RBAC, audit logs, and change requests; OSS version lacks full governance features

#1 in Feature Management for 3 years running.

Trusted by product teams. Proven in production.

See why customers love us

Built for product velocity. Trusted by data-driven teams.

LaunchDarkly empowers teams to ship, test, and iterate at enterprise scale — with the safety, speed, and targeting control open‑source tools can't match.
