WrenAI

★ 4/5 · Analytics

Open-source generative BI engine that converts natural-language questions into governed SQL, dashboards, and charts across 20+ data sources.

Pros

Open-source with 15,783+ GitHub stars
agentic multi-step reasoning with traceable steps
row and column-level access controls
20+ data sources (BigQuery, Snowflake, PostgreSQL, etc.)
embedded APIs and MCP support

Cons

Tiered licensing (OSS vs. Cloud vs. Self-hosted) requires choosing deployment model
governance and enterprise features require paid tiers

Cost

The open-source CLI and Rust context engine are free; on Wren AI Cloud the Free plan is $0 with 20 credits a month plus 80 extra credits for the first 14 days, Essential Cloud is $179/month billed annually with 13,200 credits a year, and Enterprise Cloud is $559/month billed annually with 24,000 credits a year, both rolling unused credits over up to twice the monthly allowance and charging $0.10 per extra credit; the self-hosted Enterprise Plus tier is custom-priced on an annual contract starting at 10 concurrent sessions.

Verdict

Best for data teams wanting open-source GenBI with built-in row/column access control and flexibility to self-host or upgrade to managed enterprise versions.
