Git-native REST client and API testing in VS Code. YAML .mmt files in Git — same files in CI via testlight.

Hey Product Hunt — I’m Mehrdad, maker of Multimeter.

I built this because I wanted API testing that lives in Git like code: YAML .mmt files you edit in VS Code/Cursor, then run the same files in CI with testlight. No cloud collections, no account.

What’s in this launch:

  • HTTP, GraphQL, gRPC, WebSocket

  • Visual editor ↔ YAML sync

  • Optional MCP (npx -y mmt-mcp) so Cursor/Claude can scaffold and run tests

  • Open source (Apache 2.0)

Try it: 
 Extension: search “Multimeter” in VS Code / Open VSX
 90s demo: 

Happy to answer anything — what would make this useful in your workflow?
