A free Postman alternative with no account, no cloud and plain-file collections

Gostman is an open source API client for REST, GraphQL, gRPC and WebSocket. It launches here on October 26.

What sets it apart: it works without an account or cloud sync, collections are plain YAML files you can commit, the desktop app, web app and CLI run the same Go engine, and an MCP server lets coding agents send your saved requests with secrets redacted.

If you use Postman, Insomnia, Bruno or Hoppscotch today, what would make you move, and what keeps you where you are? I'm reading every reply.
