Multimeter is a Git-native REST client and API testing tool for VS Code and Cursor. Requests and tests are YAML .mmt files in your repo — the same files in the editor and in CI via testlight. HTTP, GraphQL, gRPC, WebSocket. Optional MCP (mmt-mcp) so agents can scaffold and run tests. Apache 2.0. No account.
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: https://mmt.dev
Extension: search “Multimeter” in VS Code / Open VSX
