Core features

Everything under one roof.

SteamVault replaces a dozen different tools with one fast, self-contained application.

01

Multi-source decryption pipeline

Keys are resolved from six independent sources at once — local database, persistent cache, GitHub ManifestHub, community mirrors, live Steam CDN, and cross-depot derivation. Up to eight parallel requests.

await Parallel.ForEachAsync(depots, async (depot) => {
    // 6 sources, 8 concurrent workers
    var key = await ResolveKeyPipeline(depot.Id);
});
02

Steam catalog browser

Browse trending, top-selling and newly released games from Steam's live storefront. Player counts from SteamDB, Metacritic scores and review percentages, side by side.

03

Offline library tracking

Save game configs locally to your vault. SteamVault diffs stored manifests against live Steam data and flags updates automatically — without the Steam client running.

04

Lua config export

Auto-generate Lua scripts with complete DLC unlocking. Export everything into a timestamped ZIP for backups or sharing with friends.

05

Themes & appearance

Thirteen built-in themes — Dark, AMOLED Black, Midnight Blue, Emerald Night and more. Hot-swap at runtime without restarting the app.

06

Community & support

Join the Discord to request missing game keys, report bugs, or talk with other users. SteamVault is fully open source — contributions are welcome.

Under the hood

Parallel decryption engine

A fallback waterfall resolves missing keys across six distinct sources concurrently, so the highest possible hit rate is reached in a single pass.
