Requestly

An lightweight, privacy‑first API client designed for modern development teams. It lets users create, test, and debug REST and GraphQL endpoints, supporting pre‑request and post‑response JavaScript scripts, environment variables, and authorization management. Collections can be organized locally, imported from or exported to formats such as cURL, Postman, and OpenAPI, and synchronized with Git repositories or shared team projects without requiring a cloud login.

The desktop‑only application runs on macOS and offers features like multi‑workspace views, local logs of API calls, and role‑based access control for collaborative work. A complementary Chrome extension can intercept, modify, and mock HTTP traffic, providing additional tooling for web development.

Targeted at developers who need a fast, open‑source solution with full data sovereignty, the client is free for up to ten collaborators and can be self‑hosted for enterprise use. Its focus on minimal bloat and Git‑friendly workflow distinguishes it from larger, cloud‑centric API tools.
