Insomnia

Built on Electron, Insomnia stores Chromium disk cache entries for its interface, V8 compiled code cache for faster startup and workspace rendering, GPUCache data such as WebGL and shader-related blobs, and diagnostic log files used for troubleshooting. These files help the app load request collections, tabs, and UI assets more quickly, but they can become stale after app or graphics driver updates. Kudu removes Insomnia's Cache_Data, Code Cache, GPUCache, and log files while leaving response history, collections, environments, settings, and stored secrets untouched.

Why clean Insomnia?

  • Stale Chromium disk cache entries can make parts of the Insomnia interface load incorrectly, showing missing icons, blank panes, or outdated UI assets until the cache is rebuilt
  • Invalidated V8 compiled code after an Insomnia update can cause unusually slow launches or a long pause when opening large workspaces while Electron regenerates bytecode
  • Old GPUCache data from a previous graphics driver version can trigger rendering glitches, black windows, flickering panels, or sluggish scrolling in the request editor
  • Corrupted cached frontend resources can leave the app stuck on a loading screen or cause workspace tabs to open with incomplete content even though the underlying data is still present
  • Accumulated diagnostic logs can quietly consume hundreds of megabytes, especially after repeated sync, plugin, or network errors, leaving users wondering why Insomnia's profile folder keeps growing
  • Oversized cache folders can increase profile backup and roaming sync time on systems that copy AppData or home-directory configs, making sign-in or desktop sync feel slower
  • After a crash or forced shutdown, partially written cache files can lead to odd one-off behavior like missing theme elements or delayed sidebar rendering that disappears once the cache is cleared
