Requestly API Client is a tool for designing, building and testing APIs in one place, positioned as a privacy-first alternative to Postman. This GitHub repository is the community hub: it is where users report bugs, request features, ask questions and browse the roadmap, and the README states plainly that the application itself is closed source.

The client supports a REST API playground, pre and post scripts, import and export from cURL, Postman and OpenAPI, GraphQL with schema introspection and autocompletion, Git sync for keeping collections in a repository, and local workspaces stored as files with no cloud storage. Topics also mention gRPC and WebSocket. You can choose local, team sync or self-hosted setups to keep control of your data, and the project advertises flat pricing that is free for up to 10 collaborators.

Desktop downloads exist for macOS on Apple Silicon and Intel, Windows and Linux. Because the repository lists the license as Other and the app is closed source, readers looking for fully open-source software should not assume the client can be audited or modified.
