API Circle Studio is a Git-backed, AI-native API workspace for developers.

Most API clients keep collections inside a separate cloud workspace. API Circle takes a different approach: your API workspace can live closer to your code, as plain JSON that can be reviewed through Git branches, diffs, and pull requests.

It helps developers create, run, mock, sync, and maintain API workflows across Desktop, Web, VS Code, CLI, and AI clients.

With API Circle Studio, you can:

1. Create and organize API requests

2. Manage environments and variables

3. Run local mock servers from OpenAPI, Postman, or Insomnia specs

4. Sync API workspace changes through GitHub

5. Review API changes through pull requests

6. Use the VS Code extension to run requests and mocks without switching tools

7. Connect AI clients through MCP so agents can read, author, and run API workflows

The goal is simple: make API development feel more like software development — versioned, reviewable, local-first, and AI-native.

API Circle Studio is source-available, self-funded, and actively evolving.
