License: AGPL-3.0 — AGPL on the OSS server; some downstream connectors are Elastic License v2.
Good fit for Teams that want a CDP shape — events fan out to many tools — and are happy doing analysis in a separate BI layer.
Weak at Not an analytics tool by itself; you still need Metabase / Superset / a warehouse to do funnels. Higher overall stack count.

Replaces these SaaS
- Amplitude · Product analytics / event tracking / funnels
RudderStack is shaped like a Segment / CDP — it ingests events and forwards them to destinations. To replace Amplitude: write a destination (or use the built-in Postgres / ClickHouse warehouse destination) and run analysis with Metabase or Superset on top. Amplitude SDKs swap to the RudderStack SDKs with similar APIs; backfill via Amplitude's Export API into your warehouse.
