Requestly

Requestly is a privacy-first API client and HTTP interceptor bundled into a single desktop app and browser extension. It lets developers send requests, organize collections, set up environments, write pre-request and post-response scripts, and automate API tests—all without requiring an account. Data stays local by default, with optional team sync via Git or self-hosted deployment for full data sovereignty. The HTTP interceptor browser extension enables real-time interception, recording, debugging, and modification of HTTP requests and responses, including URL redirects, header modification, mocking API responses, and injecting custom JavaScript. This dual-product approach serves backend developers, frontend engineers, and QA teams, covering both API development and network debugging in one unobtrusive tool. Key features include an API client with unlimited collections and environments, Git-based collaboration (Free plan: 3 team projects, 10 collaborators), AI-powered test authoring (Pro), AWS Secrets Manager integration (Pro), and support for GraphQL with schema introspection. You can import collections from Postman, cURL, and OpenAPI specs with one click. The Pro plan costs $12/user/month ($9 billed annually), while the Free tier offers substantial functionality for individuals and small teams. Requestly is SOC 2 compliant and supports SSO for enterprise governance. Positioned as a direct alternative to Postman, Requestly differentiates itself with flat, predictable pricing, local-first storage, and no mandatory login. While Postman has grown into a complex platform, Requestly stays lean and developer-centric, making it ideal for teams that value simplicity, speed, and data control. Recent updates include AI test authoring (launched January 2026) and the ability to chain API requests (blogged July 2026).
