Modrix
What it is
Modrix is a free, open-source game mod manager with graphical, terminal, and command-line frontends sharing one engine. The project presents it as a Vortex replacement for people managing game mods. It lists built-in support for 86 games, with additional titles installable through a community plugin registry. A browser extension passes Nexus Mods download links and session cookies to Modrix so it can download and stage files without a Nexus API key. On Linux, Steam and Proton are described as first-class options; Modrix usually detects Steam-installed games and offers an add-and-switch action. Deployment uses hardlinks where possible, backs up files before overwriting them, journals changes for crash recovery, and can be reversed. It detects conflicts between enabled mods and offers rules and per-file overrides to address them. The CLI supports scripting and JSON output, and an MCP server exposes engine functions as tools for agents. The project says it has zero telemetry and that Lua game plugins are sandboxed, with file changes handled by the core engine. Modrix uses the GPL-2.0-only license. Its listed releases are pre-releases; macOS has no prebuilt binary, and Linux and macOS do not auto-update in-app.

The verdict
Modrix brings deployment safeguards and several ways to manage mods in one engine. Consider its pre-release status and macOS installation requirement before choosing it.
Who it suits
Modrix suits game mod users who want GUI, terminal, or CLI controls and need mod profiles or conflict handling. Linux users with Steam or Proton games may also find its stated detection workflow relevant.
