Requestly is a lightweight, Git-native API client and HTTP interceptor that lets developers build, test, and modify APIs locally without required login or cloud dependency.
What is Requestly?
Requestly is a developer tool that combines a desktop API client with a browser extension for intercepting and modifying HTTP traffic. As an API client, it accepts endpoints, collections, and environment variables as input and returns API responses, with all data stored locally in plain JSON files. As an HTTP interceptor, it runs in Chrome, Edge, Firefox, Opera, Safari, Vivaldi, and Brave to redirect URLs, modify headers, mock GraphQL/API responses, and inject custom JavaScript. The product is developed by Requestly and is trusted by over 300,000 developers from Fortune 500 companies including Microsoft, Amazon, and Google.
Key Features
- Git-Native Local Collections — API collections are stored as plain JSON files in a local directory, enabling direct version control with Git and team collaboration without cloud lock-in.
- Pre & Post Scripts — Run JavaScript before a request is sent and after a response is received, allowing dynamic header adjustment or response processing.
- REST API Playground — Send requests to any REST endpoint and inspect responses in a clean, lightweight interface with no mandatory sign-up.
- Multi-Workspace View — Manage multiple local workspaces simultaneously, each with its own set of collections and environment variables.
- GraphQL Support — Test GraphQL endpoints with schema introspection, auto-completion, and variable management.
- Easy Import/Export — Import collections from cURL, Postman, or OpenAPI formats; export to JSON for sharing or migration.
- Collaboration & Git Sync — Share workspaces with up to 10 collaborators for free, with the option to sync collections to a Git repository for team review.
- Enterprise Security — SOC‑2 compliant, supports Single Sign-On (SSO), role-based access control (Admin, Editor, Viewer), data encryption, and audit logs. Self-hosting available for complete data sovereignty.
Who is it for?
- Frontend developers — Debug API responses in real time by intercepting and modifying HTTP requests from the browser.
- Backend developers — Test and mock REST or GraphQL endpoints locally without cloud dependency, using pre-request scripts to set up test data.
- Engineering teams — Collaborate on API collections via Git sync and shared workspaces, with role-based permissions to control access.
- Enterprise developers — Use self-hosted deployment and SOC‑2 compliant infrastructure to meet internal security and data privacy requirements.
What can you do with Requestly? (Use cases)
- Intercept and modify HTTP traffic — Redirect URLs, change headers, or mock API responses directly in the browser extension without altering the production server.
- Sync API collections across a team — Store collections as plain JSON in a Git repository; team members pull changes, review via pull requests, and push updates—all without a central cloud service.
- Test APIs with dynamic inputs — Use environment variables and pre‑request scripts to parameterize requests across staging, production, or local environments.
