SchemaCrawler
SchemaCrawler is free, open-source software for discovering database schemas, documenting them, and supporting data governance. Its command-line tools output metadata as plain text, HTML5, HTML5 with embedded diagrams, JSON, or YAML. These formats are intended to make differences between database schemas easier to identify. SchemaCrawler can generate entity-relationship diagrams and execute JavaScript or Python against a live database connection. It supports almost any database with a JDBC driver, although some proprietary drivers require separate downloads. Integrations documented by the project include Apache Maven, GitHub Actions, GitLab pipelines, Docker, Graphviz, and several templating engines. The AI MCP Server allows natural-language exploration of database structures, table relationships, and SQL query generation. SchemaCrawler runs on operating systems supporting Java SE 17 or newer and can be self-hosted. The software is free; bundled JDBC-driver distributions are GPL v3, and commercial-use licensing terms can be arranged.
