DB Migration Script Generator
Compare two CREATE TABLE schemas and generate ALTER, CREATE, and DROP migration SQL.
About this tool
Generate ALTER and CREATE migration SQL from two CREATE TABLE schemas. PostgreSQL, MySQL, SQLite — free, private, in-browser. DB Migration Script Generator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- DB Migration Script Generator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
