Best Self-hosted Alternatives to Testfully

Yaade is an open-source, self-hosted, collaborative API development environment. It enables teams to store, organize, and test API work on their own infrastructure, promoting secure collaboration and sharing of API collections.

Key Features

• Self-hosted: data never leaves your own server.
• Multi-user: manage users and their permissions.
• Persistent: data remains consistent across container or server restarts.
• Easy single-file data import / export.
• Proxy requests through your browser or through the server.
• REST and Websockets with Markdown documentation support.
• Scripts: run cron jobs or API-based scripts; execute requests or tests in pure JavaScript.
• Import collections from OpenAPI or Postman; export to multiple languages and frameworks.
• Dark mode is the default UI experience.

Use Cases

• Collaborative API development and testing: teams can share and co-edit API collections and tests in a self-hosted workspace.
• OpenAPI/Postman imports and client generation: migrate existing API definitions into Yaade and export to various languages/frameworks.
• Secure, on-prem API workbench: run Yaade on your own server with user permissions and persistent data across restarts.

Limitations and Considerations

• No hosted cloud instance is described by default; Yaade is built as a self-hosted solution and is typically deployed via Docker. For installation guidance see the official docs.

Conclusion

Yaade provides a self-hosted, collaborative environment for API development, testing, and documentation. Its emphasis on on-premises data, multi-user access, and OpenAPI/Postman compatibility makes it suitable for teams prioritizing security and shareable API workspaces.
