Hudders
Hudders are the small headers Hud's IDE extension adds above each function in your editor. Each one shows how that function behaves in production, so you see it while you read or change the code.
What a Hudder shows
- Calls per day, and how many flows the function runs in, for example
3,683/d (1 flow). - Duration: the average over the last 7 days. An up arrow means it's rising, and a flame means it at least doubled against the period before, as in
2.53s↑🔥. Calls per day get the same flame. - Error rate, for example
0%err. - Last deployed change: how long ago a new version last changed the function.
A function Hud has mapped but that hasn't run yet shows Not invoked yet. Hudders also appear on inline functions, such as a callback passed to forEach.
Click a Hudder to open the Hud panel at the bottom of the editor. It shows the function's call graph from production: which functions call it and which ones it calls. Thicker lines carry more calls, and failing paths are marked in red. Click a caller or callee to jump to it, or select More info to open the function's page in the web app.
Where Hudders appear
Hudders appear in VS Code, Cursor and other VS Code-based editors, and in JetBrains IDEs. You need the Hud SDK running in the service and the Hud extension installed and signed in.
Hudders appear only on functions Hud has mapped in your own code, not on third-party code.
