Ariana is an IDE extension to understand what happens during runtime. You don't have to put print(), console.log() or breakpoints. Currently supports JS/TS & Python.
Use Ariana VSCode extension to :
- 🕵️ Hover over any expression to see its last recorded values
- ⏱️ See how long it took for any expression in your code to run.
- 🧵 Provide runtime history to coding agent for context-aware debugging (WIP)
Install the extension on the VSCode Marketplace, or by searching for Ariana in the extensions tab in VSCode or Cursor.
