Vackle gives Flackle wings.

A client mod for Flackle with 48 plugins, themes and a live CSS editor.

Version 0.3.5, free and open source.

Before you install

  • Client mods are against Flackle's Terms of Service. Vackle runs inside your own app and never automates your account, but if losing it would be a disaster, don't use a client mod at all. Keep screenshots of Vackle out of servers that might ban you for it.

  • No. Vackle loads alongside Flackle and never edits its files. Your QuickCSS and themes are saved in Vackle's own data directory.

  • Run Vackle.exe again to uninstall. Everything returns to exactly how it was before.

  • Every release is signed and checked before it installs. If an update fails, Vackle rolls itself back.

  • Yes, on flackle.com in Chrome, Edge, Brave and Firefox, as an unpacked extension. The download page shows the three steps.

  • Nothing. Vackle is free software under GPL-3.0-or-later, and the source is on GitHub.

Vackle.exe for Windows, version 0.3.5. Open it once to install, again to uninstall.
