Requestly

Requestly is a desktop‑only API client that lets developers create, test, and debug HTTP and GraphQL endpoints. It supports sending requests, managing collections, environments, and variables, and provides pre‑ and post‑request scripting to modify traffic or process responses. The tool includes a REST playground, schema introspection for GraphQL, and the ability to import and export data from formats such as cURL, Postman, and OpenAPI.

The application is positioned for engineering teams that need local control over their API work. Projects can be kept purely on the machine, synchronized through Git, or self‑hosted, ensuring that data never leaves the user’s environment. Collaboration features include shared workspaces, role‑based access, and a history log of API calls.

Requestly emphasizes a lightweight, developer‑first experience without cloud lock‑in, offering a free tier for small teams and flat pricing for larger enterprises. It runs on macOS and is marketed as a privacy‑first client for modern development workflows.
