Requestly

Requestly is a desktop API client for designing, sending and testing HTTP requests. It keeps projects as files on your machine, and it can bring in collections from other tools.

Requestly gives you a workspace for organising API requests, environments and variables. You can write pre-request and post-request scripts, add tests and run them against a collection. Projects can stay local or sync to a team, and they can be kept in Git. The app also includes mock servers, so you can return fake responses while the real backend is still being built. Collections can be imported from Postman, Insomnia, cURL or OpenAPI files.

• Import collections from Postman, Insomnia, cURL or OpenAPI
• Keep local projects as files that work with Git
• Manage environments and variables per project
• Write pre-request and post-request scripts and tests
• Run mock servers to return fake responses

Developers and QA engineers who send many requests during daily work will find the workspace helpful. Teams that want to move away from Postman can bring their existing collections across without rebuilding them by hand.

The app is available for Windows, macOS and Linux. The company describes its pricing as flat and per user, and it offers local, team sync and self-hosted options for data. Check the current plan details on the site before rolling it out to a larger group, since limits can differ between plans.
