Open source from Checkpoint Zero
Built in the open.
Free to play with.
Alongside the community, we make free software for playing on PC. Every line of it is public: read the code, grab a release, and tell us what to build next.
Free · Open source · MIT licensed · Windows
Our first tool
ZeroPad. Your controller, your way.
A free, open-source home for your PC controllers. Make a supported PlayStation controller work in games that expect an Xbox pad, then tune how it feels.
ZeroPad · app previewEarly alpha
Get into the game
Turn on a virtual Xbox 360 controller for games that expect XInput. You decide when it starts.
Xinput outputMake it feel right
Save profiles for button mapping, stick dead zones and trigger response, and switch them for each game.
Saved profilesA personal touch
Set the lightbar colour and brightness, adjust rumble, and check battery and charging at a glance.
Lights & feedbackEarly alpha for Windows 10 and 11. DualSense and DualShock 4 are supported today; more controllers are planned.
Why open source
Good tools should be within everyone's reach.
The software around your games should be easy to trust and free to use. So we build ours where everyone can see it.
Read every line
All the code is public. See exactly what a tool does with your controller and your PC before you run it.
Free, for good
No accounts, no subscriptions, no ads. Download a release and it's yours. Reading the code needs no account either.
