Vivaldi

Built on Chromium, Vivaldi stores a large browser cache under its profile for HTTP disk cache entries, media cache, GPUCache data, Code Cache bytecode, Service Worker cache storage, and SQLite-based history and site data databases with WAL and journal files. These files speed up page loads, video playback, script startup, and offline web app behavior, but they can also become stale, oversized, or fragmented over time. Kudu removes disposable cache content and cleans up temporary database side files while leaving bookmarks, saved passwords, accounts, settings, and personal browsing data intact unless they are part of the selected cache target.

Why clean Vivaldi?

  • Stale HTTP cache entries can keep serving an older copy of a site after it has changed, so pages look broken, styles are missing, or login screens loop until the cache is cleared
  • Invalidated Code Cache bytecode after a Vivaldi or Chromium engine update can make the first launch of web apps and heavy sites noticeably slow while JavaScript is recompiled
  • Outdated GPUCache data after a graphics driver update can cause black rectangles, flickering tabs, or choppy scrolling until Chromium rebuilds its GPU shader and render caches
  • Corrupted media cache files can lead to videos that buffer forever, restart unexpectedly, or play audio with a blank player area even though the connection is fine
  • Service Worker cache storage can preserve an old offline copy of a site, causing PWAs and webmail to show stale content, fail to sync, or ignore recent server-side fixes
  • An oversized browser disk cache can consume multiple gigabytes in the profile directory, leaving Vivaldi updates, downloads, or other apps short on free space
  • SQLite databases used by Chromium-based browsers can accumulate page fragmentation over time; vacuuming rewrites the database file to compact unused pages without deleting your actual rows, which can reduce profile bloat and occasional sluggishness in history-backed features
