Summary

ChartDB is a database visualization and diagramming tool for developers and product teams who need to understand, design, and manage database schemas. It retrieves a schema with a single query and says it can turn that schema into a diagram in about 15 seconds. In its editor, users can work with tables, fields, relationships, layouts, colors, and filters. Diagrams can be exported as SQL, images, diagram JSON, or DBML. Listed database support includes PostgreSQL, MySQL, SQLite, SQL Server, MariaDB, ClickHouse, CockroachDB, and Cloudflare D1. Teams can invite people to view or edit diagrams in real time; other listed features include synchronization, schema-change diffs, and version history. AI tools can generate schema diagrams and ERD visualizations. ChartDB says AI providers, including OpenAI, may process inputs, outputs, and personal information. Its free plan allows one user, one database, and 10 tables per diagram. Pro is $25.00 USD per month; Teams is $59.00 USD per month. A free, open-source self-hosted version is also available.
