Spec score 8.0 #5 of 39 in ROM Management Software

What it is

Gaseous Server is a free, open-source self-hosted server 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 the built-in emulator covers a documented subset including Game Boy, Nintendo 64, PlayStation, Sega Saturn, and Super Nintendo. Installation options include Docker, source, Unraid, and a Windows MSI package. Windows installation is described as experimental. Setup requires MariaDB 11.1.2 or MySQL Server 8+ and FFmpeg; an IGDB API key is optional when using the Hasheous proxy. From version 2.0, authentication includes passwords, two-factor authentication, and OAuth2/OIDC, with Google, Microsoft, and custom OIDC providers documented. The project uses the AGPL-3.0 license and links to Discord for community support. Maintainers recommend avoiding internet exposure when remote access is unnecessary and state that exposure is at the user’s own risk. The free plan is a self-hosted server, so the operator supplies the database and FFmpeg.
