Very strong launch reception for a BI tool. YC backing.
Evidence
activeBI-as-code platform: SQL + Markdown → polished data reports. No JS/Python required. YC S21, 6K stars, 76 contributors. Git-versioned reports for SQL-first analysts.

Where it wins
SQL + Markdown authoring — no JS/Python required
Git-versioned reports — fits developer workflows and agent-assisted authoring
YC S21 backed with strong launch traction (263 pts HN)
Clear, defensible niche: SQL-only BI as code
76 contributors — healthy open-source community
Alternative to Looker/Tableau for teams that prefer code over drag-and-drop
Where to be skeptical
Lower download numbers than peers (7.7K npm/mo)
Less AI-native than Marimo or Data Formulator — reporting tool, not conversational agent
No notebook/exploratory mode
Editorial verdict
Best BI-as-code platform for SQL-first analysts. If your team thinks in SQL and wants version-controlled, code-authored reports, Evidence beats every other tool. The only tool in the category that doesn't require a general-purpose programming language.
