Nebula Download free
Download

Get Nebula for Windows.

Free, no account and no card. Pro features can be tried from inside the app whenever you're ready.

  1. Download and unzip

    Unzip the folder anywhere you like — for example C:\Program Files\Nebula or your Documents — and run ControllerMapper.exe.

  2. Install .NET 8 if Windows asks

    Nebula runs on Microsoft's free .NET 8 Desktop Runtime. Windows offers to fetch it the first time if it's missing.

  3. Plug in your controller and map

    It shows up in the status bar. Open Mapping, click a button on the drawing, choose what it does, then turn the mapper on with the switch or F8.

  4. Optional: the virtual controller drivers

    For a virtual Xbox 360 / DualShock 4 controller, install ViGEmBus. To hide your real controller from games, install HidHide. Both are free, open source and made by Nefarius; Nebula links to them when you need them.

Early-access builds aren't code-signed yet.

Windows SmartScreen may say it "protected your PC". Choose More info → Run anyway, after checking the file's SHA-256 against the one on this page. Signed builds are coming with the installer.

System requirements

Uninstalling

Delete Nebula's folder. Your profiles and settings live in %LocalAppData%\NebulaControllerMapper; delete that too for a clean slate. If you used "Hide the real controller", Nebula has already put HidHide back the way it found it.
