Windsurf IDE
Built on an Electron and Chromium stack, Windsurf IDE writes several local caches to speed up startup, extension host loading, and webview rendering. These include Chromium HTTP disk cache entries in Cache_Data, V8 compiled script bytecode in CachedData, cached extension packages in CachedExtensions, and session log files used for diagnostics. Kudu removes those disposable caches and logs so Windsurf can rebuild fresh copies without touching projects, source files, installed settings, accounts, or saved credentials.
Why clean Windsurf IDE?
- Invalidated V8 bytecode in CachedData after a Windsurf update can make the next launch unusually slow or leave extension webviews loading longer than normal until the cache is rebuilt.
- Corrupted Chromium disk cache entries in Cache_Data can cause blank panels, missing icons, or sign-in and marketplace pages that never finish rendering inside the IDE.
- Stale cached extension packages in CachedExtensions can leave an updated extension stuck on older assets, showing mismatched UI, broken commands, or repeated activation errors in the extension host.
- Accumulated logs from repeated crashes, extension failures, and background service restarts can quietly consume hundreds of megabytes, which users usually notice as Windsurf taking far more disk space than expected.
- Old cache records tied to expired sessions or redirected endpoints can make built-in web content loop on loading, fail authentication checks, or show outdated marketplace results until the cache is cleared.
- After network interruptions or forced shutdowns, partially written cache files can trigger odd startup behavior such as a white window, unresponsive settings panes, or developer tools errors in the logs.
