API Circle Studio is a Git-backed, AI-native API workspace for developers. Build collections, environments, mocks, assertions, and execution plans across Desktop, Web, VS Code, CLI, and MCP. Workspaces live as JSON you can diff, review, and sync through Git — while Claude, Cursor, Copilot, and ChatGPT can read, author, and run requests through MCP. Source-available, local-first, and built for API teams that want ownership.

Hey Product Hunt 👋 I’m Deva, the maker of API Circle Studio. I built API Circle Studio because API development is changing. Code already lives in Git. Teams already review changes through pull requests. AI assistants are now helping developers write, test, and understand code. But API workspaces are still often locked inside tools, hard to diff, and disconnected from the rest of the development workflow. API Circle Studio is my attempt to rethink that. It is a Git-backed, AI-native API workspace where you can: • Build API collections, environments, mocks, assertions, and execution plans • Store the workspace as JSON that can be committed, reviewed, and diffed • Run local mock servers from OpenAPI, Swagger, Postman, or Insomnia specs • Work across Desktop, Web, VS Code, CLI, and MCP • Let AI clients like Claude, Cursor, Copilot, and ChatGPT read, author, and run requests through MCP The core idea is simple: Your API workspace should be readable by developers, reviewable in Git, and driveable by AI. API Circle Studio is still early and source-available. I’m launching today to get honest feedback from developers, API platform teams, and people exploring AI-native development workflows. I’d love to hear: • Would you use a Git-backed API workspace? • Would MCP-powered API workflows help your team? • What would make this a serious alternative to Postman or Insomnia for you? Thanks for checking it out 🙏

What should an AI-native API workspace do better than today’s API clients?

API Circle Studio is launching tomorrow.

I m building it around one idea: API workspaces should work more like code.

That means:

Collections and environments should be readable and git-diffable
API changes should be reviewable through pull requests
Local mocks should be part of the workflow, not a separate setup
AI clients should be able to read, author, and run API workflows safely through MCP
