Coda Controller Lab
Free tools for the controller on your PC: check that every input works, measure stick drift, stick range and how often new input arrives, shape how your sticks respond, and put your pad on stream. They run in your browser — no sign-up, nothing to install, nothing stored, nothing sent anywhere.
- Is every input working?Gamepad TesterEvery button, trigger and stick of any controller your PC sees, with live values and the controller drawn as it moves. Includes a rumble test.Open →
- Does a stick drift?Stick Drift AnalyzerRecords both sticks at rest: where each settles, how far it strays, how much it wanders, and the smallest deadzone that hides it.Open →
- How far does each stick reach?Circularity AnalyzerTurn a stick along its edge and see the outline it reports, how its diagonals compare with straight directions, and left against right.Open →
- How often does new input arrive?Input Update Rate AnalyzerHow often your browser receives new controller data, with the gaps between updates and their jitter — clearly labelled as the browser's rate.Open →
- How should your stick respond?Response Curve EditorShape a stick response curve with up to ten points, start from Coda's curves, and copy it into Coda as a code.Open →
- Your inputs on stream.Controller Overlay for OBSA DualSense overlay in eight themes or your own colours, added to OBS as a Browser Source on a transparent background.Open →
Through the browser’s standard Gamepad API, which sees any controller Windows recognises. Browsers only let a page see a controller after a button press, so press one once when a tool says it is waiting.
The tools work with any controller and without Coda. With Coda running, the controller your browser sees is Coda’s virtual one, so the tools show your inputs as games receive them — after your curves, deadzones and remapping. To measure the stick itself, disconnect Coda first. What Coda does.
