Auxl is a native API client for macOS. Its powerful node based system provides a whole new way to organise, test, and develop API projects.

Pick and choose from an ever-expanding toolkit of modules. Use any combination of REST, GraphQL and WebSocket sources. Authenticate, perform regular expressions, run Javascript, generate dates, hashes, nonces, and much more.

Auxl provides a flexible space to interact with APIs of any complexity. Whether it's sending a simple form, uploading a file to S3, or building out a custom authentication scheme.

Use the output of a module as input for another to create dynamic configurations and payloads. Great autocomplete support makes it easy to discover and insert variables.

Auxl's console-style output reduces clutter by putting you in control of what gets displayed. It's themeable, has great syntax highlighting, preview support, and handles large responses with ease.

Robust HTTP client: Auxl's full-featured, high performance HTTP client supports a wide range of standards and protocols, including: HTTP/2, Brotli, and TLS 1.3.

Security & Privacy: Your secrets and passwords are kept safe by default with strong encryption. Enable full project encryption for an additional level of security. At no point does any of your information leave your Mac.

A Native Experience: Enjoy excellent performance, great battery life and a look and feel that is right at home on macOS. Auxl runs natively on both Apple Silicon and Intel Macs.

Snippets: Create snippets of your compositions to quickly reuse them. Your most used operations are just a few keystrokes away.

Extend and Automate: Use Javascript to write assertions and data transformations. Build exit conditions for browser or web sockets to further automate your API flows.

Learn by Example: You'll find that working with Auxl is very intuitive. However, it you need it, ample documentation and examples are included.
