F1 Mod Manager | Mods for F1 25

The F1 25 home menu with MOD SETTINGS under Career, the "Launched with Swofty Mod Launcher" panel and the F9 prompt — MOD SETTINGS in the game's home menu

F1 Mod Manager is a launcher and mod loader for F1 25 on Windows and Linux. Add community tracks, install mods, change mod settings in game and keep separate profiles. Modded play is offline only, and launching from Steam stays vanilla.

Windows 10 and 11
Linux with Steam and Proton
Steam Deck

Everything in one launcher

Maps

Import community track packages, such as Sepang and Okayama, and race on them as extra tracks.

Mods

Install, enable and disable mods. The app warns you when two mods change the same thing.

In-game mod settings

Open MOD SETTINGS in the game's home menu, under Career, to change mod options without leaving the game.

Profiles

Switch between separate sets of mods and maps, each with its own saves. The original game is always restorable in one click.

Offline-only modded play

Modded sessions always run offline with multiplayer off. Launching from Steam normally stays completely vanilla.

The launcher app

Manage everything and press Play in one window, with live logs to help if the game crashes.

F1 Mod Manager is open source, with a hook system built for modders. Mods hook game functions by name, with priorities and chaining so several mods can change the same function.
