What it is

Chion turns plain-English questions about PostgreSQL into code-validated, read-only SQL and interactive D3 charts, displaying the SQL beneath each chart. It connects directly to PostgreSQL without ETL or a warehouse copy, supporting Amazon RDS, Azure Database for PostgreSQL, Google Cloud SQL, Neon, Supabase, and self-hosted PostgreSQL. Validators reject statements that are not read-only SELECT queries before database execution. Results are limited to 1,000 rows or 12,000 cells. Eight built-in chart types include line, area, bar, and animated bar-race formats. Saved queries can become portable SQL skill files for Claude Code and Codex. Chion runs in the cloud through the web. Starter costs $29/seat/mo, Pro $99/seat/mo, and Max $299/seat/mo, each with a seven-day trial; Enterprise uses custom per-team pricing. Credentials are encrypted in an AES-256-GCM vault, while Chion says it is not SOC 2 certified and does not support HIPAA workloads.
