Fullstack Framework

Support languages that can be compiled on the frontend, but gives you an easily deployable Modal server for languages that can't.

Configurable Themes

Choose from a variety of themes, or create your own using ThemeMirror.

Universal Language Support

Cannon supports every language under the sun, with easy integration support to add more (client-side or server-side).

Multi-Tab Editing

Make your examples as complicated as you want with multi-tab editing - only keeping relevant lines in each tab.

Headless Mode

Easily configurable hooks to bring your own UI while using our language support.

Secure By Default

Deploy your backend on Modal with an application-layer WAF to prevent misuse.
