I built a free, open-source Postman alternative in Go: no account, collections are just YAML files

说明与用途

Gostman 是一个免费、开源的 API 客户端，无需账户，使用 YAML 存储集合，支持 CI、负载测试和编码代理集成。

问题

API clients often require an account before sending requests, hindering quick testing and automation.

结果

Gostman enables account‑free API testing across REST, GraphQL, gRPC, WebSocket, and more, with CI integration, secret management, and coding‑agent support.

工作流

• 1. Install Gostman via Go: go install github.com/kunalgoesbyken/gostman/cmd/gostman@latest
• 2. Create a collection folder with YAML files
• 3. Run requests from the CLI or desktop app
• 4. Use gostman run in CI to execute collections and generate reports
• 5. Expose collections to coding agents with gostman mcp

证据

I got tired of API clients that want an account before I can send a single request, so I built Gostman: a free, MIT‑licensed API client for REST, GraphQL, gRPC and WebSocket.

Collections are plain YAML in a folder, so they diff and review in Git like any other code.

gostman run exits non‑zero on failure and writes text, JSON, JUnit and HTML reports.

gostman mcp exposes a collection to agents like Claude Code, Codex or Cursor so they can call your requests without seeing your secrets.
