ClickyKeys is a free, open-source Windows desktop app for tracking and displaying the number of times selected keyboard keys and mouse buttons are pressed. Its positioning is very clear: it provides streamers, content creators, and gamers with a lightweight, customizable keystroke counter overlay, especially suitable for display in OBS or similar recording/live-streaming software.
In terms of functionality, ClickyKeys lets you select any keyboard key or mouse button for real-time counting, and set custom labels for each key, such as Jump or Reload. The panel appearance can be customized with adjustable button size, layout, background color, text color, font, and font size, and it also offers an animated rainbow theme. For live-streaming scenarios, it supports background colors that are easy to chroma-key out, and can also be overlaid onto an OBS window source using transparent mode. One-key reset with F12, saving/loading style profiles, automatic update notifications, and long-term local keystroke statistics make it more than just a one-off display tool—it can also handle basic usage tracking.
The project is written in C# and was rewritten in WPF in v2.0.0. It is open source under the GPL-3.0 license, with source code available on GitHub for viewing, building, or extending. It runs entirely locally, requires no account, and does not collect or send data. Integration mainly centers on OBS: after running ClickyKeys, users can add a Window Capture source in OBS and use chroma keying or transparent mode to turn it into a corner overlay for streams. The main documentation does not mention an API, SDK, or plugin system.
ClickyKeys is clearly marked as Free forever. It can be installed via the Microsoft Store, or downloaded as a portable version from GitHub Releases. Since small unsigned C# apps may trigger Windows SmartScreen warnings, users may need to manually choose to continue running it; the open-source code helps reduce the trust barrier to some extent.
Its strengths are that it is free, open source, privacy-friendly with local operation, clearly adapted for OBS, highly customizable in appearance, and quick to set up. Its limitations are that it currently focuses only on Windows, with no macOS/Linux versions; its scope is relatively narrow, mainly serving keystroke/click counting; and its documentation is mostly website explanations and FAQ content, with limited developer-level documentation. It is best suited for streamers, gameplay recording creators, users who need to demonstrate keyboard actions, and anyone who wants to track key usage locally.
The source text does not provide information about mainland China network access, mirrors, or payments. Since no payment is required, there is no payment barrier; however, the actual download experience from the Microsoft Store and GitHub Releases may depend on the local network environment, so China access status is rated as unknown. Alternatives include NohBoard, Carnac, KeyCastOW, or OBS input-display plugins.
