Install

  1. Download Seaglass-setup.exe and run it. Prefer no installer? Seaglass.exe on the release page runs from any folder.
  2. Builds aren't code-signed yet, so Windows SmartScreen may warn the first time: More info → Run anyway. Each release lists SHA-256 checksums, and updates must carry a signature from the maintainer's release key.
  3. Open Seaglass. It scans your PC and builds the library on its own.

Seaglass is a library manager: it indexes and starts games that are already installed. It doesn't download, unlock or modify games. It is an independent project, not affiliated with Valve, Epic Games, GOG, EA, Ubisoft, Blizzard, Microsoft or Sony.
