TypeSwitch
Automate Prisma to Drizzle migrations in 1-click
TypeSwitch is an AI-powered developer CLI that scans your codebase to automate Prisma-to-Drizzle database migrations and OpenAI-to-Claude API refactors. It generates clean TypeScript schemas, updates all query calls, flag edge cases, and upgrades your package dependencies instantly.
Manual database migrations or LLM client swaps are the kind of tasks engineering teams put off for months. Rewriting hundreds of database query lines or LLM API calls is tedious, time-consuming, and highly prone to silent runtime bugs.
TypeSwitch is a local CLI utility that automates these code migrations in minutes:
1. 📂 ORM Migrator (orm-migrate): Translates schema.prisma definitions into idiomatic Drizzle schema.ts. It scans your codebase, refactors PrismaClient queries into Drizzle's relational API, and swaps package dependencies.
2. 🤖 Model Migrator (model-migrate): Translates OpenAI SDK calls to Anthropic Claude messages API, automatically handles system prompt hoisting, aligns role alternations, and sets up vector re-indexing scripts.
🛡️ Safety First:
- It runs 100% locally on your machine—your source code never leaves your computer.
- It automatically backs up your codebase. If anything compiles incorrectly, run with --rollback to return to a clean Git state instantly.
- Any unmappable queries (complex SQL, transactions, streaming delta formats) are not translated blindly; they are flagged with prominent '// MANUAL MIGRATION REQUIRED' comments.
Instead of a monthly SaaS subscription, you buy a one-time license to the complete TypeScript source code—no subscriptions, no API tokens markup, no vendor lock-in.
🎉 Launch Discount:
To celebrate the launch, get 15% off any package (Drizzle Migrator, LLM Migrator, or the Full Combo Suite) by entering coupon code SWITCH at checkout!
I'll be here all day to answer your questions and chat about AST parsing, database queries, and LLM integrations. I'd love to hear your feedback! 🚀
