License: Apache-2.0 — Core OSS is Apache-2.0; some Enterprise features (advanced segments, change requests) are gated.
Good fit for Engineering teams that want a battle-tested feature-flag platform with a clean self-host story.
Weak at A/B testing depth is shallower than LaunchDarkly Experimentation; pair with PostHog or GrowthBook if experimentation is core.

Replaces these SaaS
- LaunchDarkly · Feature flags / progressive delivery
Pull `unleashorg/unleash-server` and `postgres:16`. Unleash has an Admin API for bulk-creating flags — write a one-shot script that pulls flags from LaunchDarkly's REST API and POSTs to Unleash. SDK migration: swap `LDClient` for `UnleashClient` in your app code; the API surface is similar. Edge evaluation via Unleash Edge (Rust binary) deployed near your apps for low-latency reads.
