▶ A library that stays yours
Add a game by pointing Vanta at its executable. Native, Wine, Proton, Flatpak and custom wrappers all launch from the same window. A Windows binary is recognised by its PE header, not just its extension.
v1.4.0 · released 13 November 2026
Your games. Your runners.
Your games. Your runners.
One honest launcher.
Vanta keeps a local library of the games you already own, launches native Linux builds and Windows builds through Wine or Proton, discovers the runners other launchers installed, and reports what it finds inside a game folder.
It never downloads a game, and it never claims a detected fix works.

Built to get out of the way
Everything below is in the app today — no roadmap, no placeholder screens.
⚙ Runners it finds for you
Vanta detects Wine and Proton builds from Steam (including extra Steam libraries), Lutris, Heroic and Bottles — including their Flatpak variants — plus anything you installed from Vanta or configured by hand. Pick the build per game from a dropdown.
✚ Mods without the ritual
BepInEx is detected next to the executable. Enable or disable a plugin by
toggling it — Vanta renames .dll ↔ .dll.disabled
and never edits the file. Add mods from a local .dll or
.zip, or browse the game's community on Thunderstore with
dependency resolution built in.
◇ OnlineFix — configured, not claimed
Vanta reproduces the launcher-side setup: signature detection, INI edits with backups, the FreeTP app-id swap, the Photon Newtonsoft link and launch-only Wine DLL overrides. Every file it touches is backed up first, and it never states that a fix works.
⇄ Port from Lutris & Heroic
Vanta reads another launcher's library — read-only — and brings the games over with the real runner and prefix. It never writes to, moves or deletes anything owned by Lutris or Heroic.
◑ Themes that match the desktop
System, Light, Dark, and Follow system colors, which derives the whole
palette from the active desktop theme — a Breeze Dark session looks like
Breeze Dark. The accent is always Vanta purple, #7c3aed.
文 Speaks your language
The whole interface — menus, dialogs, the tutorial, scan reports and status messages — is translated. Russian, Brazilian Portuguese, Portuguese and Spanish catalogs ship inside the binary, the language follows your desktop by default, and picking another one applies the moment you save Settings. More languages are a pull request away.
⌘ Honest diagnostics
Every launch stores its runner output in a terminal-styled log, written while the game is still running, so a game that closed on its own can be diagnosed after the process is gone.
✓ No store, ever
Vanta has no store integration and no acquisition path. It launches the games you already have and reports what it finds — nothing more.

Lutris and Heroic are both actively developed — Lutris has commits from this week even though its last stable release was in February. The row above is about release cadence, not about whether a project is alive. OFLL solves a different problem: it downloads and installs online fixes, while Vanta only configures a game you already own and never fetches anything.
The one rule
Vanta never downloads games, and detection is a signature match — not proof. Anywhere the app reports an OnlineFix or a mod, it reports what it found and what it changed. It will never tell you a fix works or that a game will run.
Get Vanta 1.4.0
A game folder copied into the library never had Steam run the game's install script, so a Wine prefix created for it can lack a runtime the game links against. Vanta now reads the failed launch output and offers to run the installer the game itself ships, in the game's own prefix.
