Liam ERD is an open-source tool that automatically generates beautiful, interactive entity-relationship diagrams from database schema files such as SQL dumps, Prisma schemas, and Rails schema.rb. It ships as a web app (liambx.com), an npm CLI for local/CI-CD use, and supports many schema formats including PostgreSQL, MySQL, Drizzle, and tbls.

Use cases

• generate an ER diagram from a postgres pg_dump schema file
• visualize a prisma schema as an interactive diagram
• document a ruby on rails db/schema.rb as an ERD
• auto-generate up-to-date ER diagrams in CI/CD on every commit
• explore and share filtered views of a large database schema with teammates
• reverse engineer an existing database schema into a readable diagram

When to choose

• you need interactive, shareable ER diagrams with zoom, filtering, and relationship highlighting
• your schema lives in SQL dumps, Prisma, Rails, Drizzle, or other supported formats
• you want zero-config diagram generation or CI/CD-automated schema docs
• you handle 100+ table schemas and need good performance

When to avoid

• you need to edit or design schemas visually rather than visualize existing ones
• you need diagrams from formats not supported by the parser
• you require a desktop-only offline tool with no web component
