FAQ
Will this get me banned (VAC / Faceit…)?
No. It uses official Game State Integration (GSI) provided by Valve, which is read-only and designed for third-party apps. It never interacts with the game in any way that would trigger anti-cheat systems.
Is this safe to use?
Yes. The full source is open. You can build it yourself, and a VirusTotal scan is attached to every release.
Does it support Linux or macOS?
Not at the moment, the audio backend is Windows-specific. The app is built with Tauri, so cross-platform support is possible. Contributions are welcome.
Is the bomb timer overlay allowed?
The timer is computed only from the official GSI data CS2 sends to the app; nothing else is read from the game. Check the rules of the platform you play on. If it does not allow overlays like this, turn off the bomb timer (or the whole overlay) with one switch.
