Superset is a full business intelligence platform you can self-host for free, with interactive dashboards, charts, and reports without writing code. Think Tableau or Looker, but open source. Connect it to Postgres, MySQL, ClickHouse, BigQuery, or dozens of other databases, then build interactive dashboards with drag-and-drop.

Fully free under Apache 2.0. No feature gating, no user limits, no enterprise unlock. You get the complete BI platform: SQL editor, chart builder, dashboard designer, role-based access, and scheduling. At, this is one of the most popular open source projects period.

The catch: Superset is resource-hungry and complex to operate. The Docker Compose setup works for testing, but production deployment requires Redis, a metadata database, Celery workers for async queries, and careful memory tuning. Expect 4-8GB RAM minimum. And the learning curve is real. Building useful dashboards takes time, and the UI can feel overwhelming. If you just need a few charts, Metabase is much simpler to get running.

Fully open source under Apache 2.0. No paid tier from Apache.

**Self-hosted cost:** The software is free but infrastructure isn't cheap. Minimum viable production setup: - VPS with 8GB RAM: ~$40-60/mo on most cloud providers - Redis instance: included on the same server or $15/mo managed - Metadata Postgres DB: can share existing Postgres or $10/mo managed

**Managed alternatives:** Preset.io (founded by Superset's creator) offers managed Superset starting around $20/user/month. At 5 users, that's $100/mo, comparable to self-hosting costs but zero ops.

**Compared to paid BI:** Tableau starts at $70/user/month. Looker requires Google Cloud contracts. Superset delivers 80% of their features at a fraction of the cost.
