- Covers flowcharts, mind maps, UML, architecture - one canvas per type.
- Image-to-diagram from screenshots.
- Live integrations with GitHub, Linear, Notion, and Drive.
- $15/mo flat Pro plan vs $25/user/mo on ChartDB Pro.
ChartDB Strengths
- AGPL-3.0 open source and fully self-hostable.
- Direct introspection from a live database connection (PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, ClickHouse, CockroachDB, Oracle, Snowflake, BigQuery).
- ChartDB Agent is a Cursor-style chat for schema design and refinement.
- Focused exclusively on database design - mature ERD-specific tooling.
The verdict
Bottom line.
Pick Raltey when you want one AI-driven tool for every diagram type, plus live integrations and a flat plan. ChartDB is the right answer when you only need ERDs, want AGPL self-hosting, and live-DB introspection beats canvas breadth.
