Our verdict on DbSketch
DbSketch is an open-source .NET CLI for developers and teams that maintain database documentation in repositories or CI workflows. It reads live schemas from SQL Server, PostgreSQL, MySQL, and SQLite, extracting tables, columns, primary keys, foreign keys, and supported database comments. The output is designed for version-controlled documentation and compact schema context for AI coding assistants, with local and self-hosted workflows rather than a hosted visual database-design service.
Its strongest differentiator is focused documentation generation. A single configuration can produce multiple focused diagrams, while Graphviz DOT and Mermaid ER outputs support different documentation environments. DbSketch also generates Markdown-wrapped documentation, uses native database comments where supported, and accepts YAML comment overrides. This combination gives teams control over how schema context is organized and maintained, particularly when documentation belongs alongside application code or runs through CI.
DbSketch is a good fit for open-source teams that want a free, repository-oriented workflow and need diagrams or Markdown documentation from a supported relational database. Its scope is narrower than a broader database platform: coverage is limited to four relational systems, it runs on Windows and Linux, and it does not provide data lineage or a hosted visual design workspace. Teams seeking focused, code-friendly schema documentation should consider DbSketch; teams needing a broader visual modeling or lineage environment should choose a different category of tool.
