Vivaldi
Built on Chromium, Vivaldi stores a large mix of local browser data under its profile, including HTTP disk cache entries, GPUCache shader and rendering data, Code Cache bytecode for JavaScript, media cache files, session storage artifacts, and SQLite databases such as History, Favicons, Cookies, and Top Sites. These files speed up page loads, preserve thumbnails and browsing metadata, and support the browser’s interface, but they can also become stale, fragmented, or oversized after browser updates, site changes, or graphics driver changes. Kudu clears disposable cache data and vacuums Vivaldi’s SQLite databases to reclaim space and resolve corruption-related issues without touching saved accounts, passwords, bookmarks, or settings.
Why clean Vivaldi?
- Stale HTTP cache entries can keep serving outdated site assets, causing pages to load with broken layouts, missing images, or login screens that never fully refresh
- Invalidated GPUCache data after a graphics driver or Chromium engine update can trigger black page areas, flickering tabs, or sluggish scrolling until the shader cache is rebuilt
- Corrupted Code Cache bytecode can make web apps and Vivaldi’s own interface feel slow on first launch, with tabs hesitating before interactive elements respond
- Oversized media and image cache files can consume several gigabytes in the profile folder, which users notice as unexpectedly high disk usage even when downloads are stored elsewhere
- Damaged favicon and thumbnail databases can leave speed dial tiles, site icons, or tab favicons blank, outdated, or mismatched with the actual site
- SQLite page fragmentation in History, Favicons, and related databases wastes disk space over time; VACUUM rewrites the database file compactly without deleting rows
- Corruption in cached site storage and session-related artifacts can lead to pages repeatedly logging out, failing to load saved state, or opening with partial content until fresh local data is created
Cache paths Kudu targets
These databases are vacuumed (compacted) — no data is deleted. SQLite VACUUM reclaims wasted space left over from normal usage.
