Requestly is a privacy-first API client designed for developers who want a lightweight, local-first alternative to traditional cloud-based API tools. It enables users to build, test, organize, and debug APIs while keeping all data stored locally by default, with optional syncing and collaboration features.

Unlike traditional API clients that rely heavily on cloud accounts, Requestly is built around a “local-first” model where requests, collections, environments, and logs are stored on the user’s machine. Developers can use it without signing in, and choose to sync data via Git or team workspaces only when needed.

At its core, Requestly provides a full API workflow environment that includes request building, response inspection, scripting, and automation. It supports REST and GraphQL APIs, environment variables, pre-request and post-response scripts, and collection-based organization of API workflows.

A key part of the platform is its Git-native and local workspace model, allowing teams to version-control API collections as plain JSON files and collaborate using familiar development workflows. This makes it especially useful for engineering teams that want APIs treated like code rather than locked inside proprietary cloud systems.

Requestly also includes a REST API playground, history logs, import/export tools (including Postman and OpenAPI formats), and testing automation features. It is designed to reduce dependency on bloated, login-heavy tools while still supporting enterprise-grade collaboration when needed.

The platform is available as a desktop application and is widely used by developers as both an API client and an HTTP debugging tool.

Key features include:

• Privacy-first, local-only storage by default (no mandatory login)
• REST & GraphQL API testing and management
• Git-native collections and environment versioning
• Pre-request and post-response scripting for automation
• Import/export support (Postman, cURL, OpenAPI)
• Optional team collaboration and workspace sync
• Built-in API playground and request history logs

Common use cases include:

• Testing and debugging APIs
• Replacing heavier tools like Postman
• Managing API collections in Git
• Simulating environments
• Running automated API workflows
• Developing APIs in privacy-sensitive or offline-first environments

Requestly is developed by Requestly Inc. and is also open-source, positioned as a modern, privacy-first alternative to traditional API clients and HTTP debugging tools.
