What Gaseous is

Gaseous Server is a free, open-source project for managing ROMs and game titles, with basic in-browser emulation. It uses multiple sources to identify games and provide metadata. ROM management supports platforms listed by IGDB, while built-in emulation covers a documented subset of systems, including Game Boy, Nintendo 64, PlayStation, Sega Saturn, and Super Nintendo. Installation options include Docker, source, Unraid, and a Windows MSI package; the installation guide describes Windows as experimental. The documented setup requires MariaDB 11.1.2 or MySQL Server 8+ and FFmpeg. An IGDB API key is optional on the wiki home page. From version 2.0, sign-in can use passwords, two-factor authentication, or OAuth2/OIDC; documented identity providers include Google, Microsoft, and custom OIDC providers. The repository identifies the project as open source under the AGPL-3.0 license. The maintainers recommend avoiding internet exposure when remote access is not needed and say exposure is at the user's own risk. Community support is linked through Discord.
