Plan game night without the guesswork
A Steam companion for groups of friends. Compare libraries to find the games everyone owns, see what is already installed, and estimate how long a download will take before the session starts.
Version 0.4.3 · Updated May 19, 2026 · First launch needs one extra step
See every game you own with playtime, a local install badge, and a multiplayer indicator. Filter by text, install status, or multiplayer support.
Condensate reads Steam’s local metadata on this machine to flag which owned games are already installed — no guessing before a session.
Add friends from your Steam friends list or by SteamID / vanity URL (up to 16) and instantly see the games everyone in the group owns.
Run a quick connection speed test, then get a realistic download-time estimate for any uninstalled game so you know what is reachable before game night.
Your Steam Web API key lives in the macOS Keychain / Windows Credential Manager — never on disk, never in logs. No analytics.
A Tauri app, not Electron: a small download, quick cold start, and a native window on both macOS and Windows.
Condensate works without a local Steam install too — you just won't see the “installed on this machine” badges.
Condensate is currently distributed unsigned, so the first launch needs one extra click to get past Gatekeeper (macOS) or SmartScreen (Windows). This is expected for a pre-1.0 build — signed installers are planned.
.dmg.xattr -dr com.apple.quarantine /Applications/Condensate.app in Terminal, then open it normally.On first run, Condensate links you to steamcommunity.com/dev/apikey. The key is free (a Steam account with a verified phone number is required) and is validated before it is accepted.
Click “Sign in with Steam” to complete the standard Steam login in your browser. Condensate captures your SteamID and shows your avatar and name.
Steam can only share your library if Profile → Privacy → “Game details” is set to Public. Condensate tells you if this needs changing — it cannot bypass other people’s privacy settings either.
Add friends from your Steam friends list or paste a SteamID / vanity URL. The shared-games view shows what everyone owns and who already has it installed.
In Settings, run “Test Connection” (5 quick samples). The result powers download-time estimates for uninstalled games in your library and the shared list.
