| What makes it different | - Multi-protocol mocking from one configuration file
- Realism-first simulation with data synthesis and failure injection
- Open source with permissive MIT or Apache-2.0 licensing
- Local-first approach with optional cloud collaboration
- Deploy to cloud hosting with a single command
| - Every API spec lives in a real Git repository with full version history, review workflow, and blame tracking instead of in a portal
- Open formats with no lock-in: OpenAPI and Markdown in Git, same checks run in CLI and CI
- Quality control through review: governance rule sets run in the editor and again in pull requests before reaching consumers
- CLI is free with MIT license, sends no telemetry, and works offline for linting, scoring and bundling
