License: MIT — Core is MIT; some Enterprise features (SSO, advanced experimentation) are paid.
Good fit for Teams that already have an analytics warehouse and want feature-flag + experimentation in one tool.
Weak at MongoDB ops surface; experimentation analysis assumes you have the warehouse pipeline already in place.

Replaces these SaaS
- LaunchDarkly · Feature flags / progressive delivery
Pull `growthbook/growthbook:latest` and a MongoDB instance. GrowthBook's strength is experimentation-first — flags + A/B tests + statistical analysis powered by your existing data warehouse (BigQuery, Snowflake, ClickHouse, Postgres). Migration from LaunchDarkly: API-pull flags, POST to GrowthBook via its Admin API; SDK migration is straightforward. Stats engine reads from your warehouse so you don't need to ship events to GrowthBook itself.
