The Auxl Toolkit

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.

Free-flowing and Expressive

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.

A few examples


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.
