Brave
Built on Chromium, Brave stores several local databases and caches under its profile, including SQLite databases for history and site data, LevelDB stores for Local Storage and extension state, IndexedDB data, Service Worker script caches, and Chromium network cache entries. These files speed up page loads, preserve offline web app state, and keep browser features responsive, but they can also accumulate stale records, fragmented pages, and orphaned cache data over time. Kudu clears Brave’s removable cache and temporary database bloat, including cache directories and reclaimable SQLite free space, without touching saved passwords, bookmarks, accounts, or browsing settings.
Why clean Brave?
- Corrupted Chromium disk cache entries can make pages load with missing images, broken CSS, or endless refresh loops until Brave fetches fresh copies
- Stale Service Worker and site storage data can keep showing an outdated version of a web app, causing login loops, buttons that stop responding, or pages that never finish syncing
- Old cached scripts and assets after a site update can trigger white pages, playback controls that do nothing, or checkout forms that fail only in Brave
- Oversized cache folders and accumulated IndexedDB or Local Storage leftovers can consume several gigabytes, which users notice as unexpectedly low free disk space
- SQLite page fragmentation in Brave’s databases wastes space and slows reads; VACUUM rewrites the database file compactly without deleting actual rows or personal data
- Damaged LevelDB state used by extensions or sites can cause extension popups to stay blank, site preferences to reset, or persistent storage errors in web apps
- Expired or inconsistent cached network data can make one site work in a private window but fail in the regular profile, a common sign that local Brave cache state is stale
Cache paths Kudu targets
These databases are vacuumed (compacted) — no data is deleted. SQLite VACUUM reclaims wasted space left over from normal usage.
