About NohBoard
The story behind the input visualizer that streamers rely on, and why we built this resource.
NohBoard is a free, open-source keyboard and mouse visualizer built for streamers and content creators. It shows your keystrokes and mouse clicks on screen in real time, making it a go-to tool for anyone who wants their audience to see exactly what inputs they are pressing during gameplay, tutorials, or live streams.
Whether you speedrun games, create tutorials, or just want to add a polished layer to your stream overlay, NohBoard handles input visualization with minimal resource usage and maximum flexibility.
The Story Behind NohBoard
From a personal project to a streaming community staple.
A Developer’s Side Project
NohBoard started as a personal project by Eric “ThoNohT” Bataille, a developer based in the Netherlands. Eric wanted a simple, lightweight way to display keyboard inputs on screen — something that worked well with OBS Studio and did not eat into system resources while gaming.
Published on GitHub
Eric released NohBoard as open-source software under the GPL license on GitHub. The source code, written in C# using GDI+ for rendering, was made available for anyone to inspect, fork, or contribute to. This transparency helped build trust in the streaming community.
Streamers Take Notice
As Twitch streaming exploded in popularity, NohBoard gained traction on Reddit, OBS forums, and streaming communities. Speedrunners and competitive gamers adopted it quickly because it had no perceptible input lag and ran quietly in the background.
The Corona Update
The latest major release, version 1.3.0 (nicknamed “The Corona Update”), shipped in April 2020. It included bug fixes and refinements that the community had requested. The project has accumulated over 1,100 stars on GitHub.
What NohBoard Does
Real-time input visualization designed for streamers and content creators.
Zero-Lag Input Display
NohBoard captures and displays your keyboard presses and mouse clicks in real time. There is no noticeable delay between pressing a key and seeing it light up on screen.
Fully Customizable Layouts
Drag and drop keys, change fonts and colors, set custom backgrounds per key, and load community-made layout packs. You can make NohBoard look however you want.
OBS-Ready Window Capture
NohBoard works with OBS Studio out of the box via window capture. Chroma key support makes it easy to overlay the keyboard display on your stream with a transparent background.
Mouse Visualization
Beyond keyboard keys, NohBoard tracks mouse buttons, scroll wheel actions, and mouse speed. Useful for FPS gamers and anyone who wants full input transparency.
NohBoard runs as a portable application — just unzip and launch. It needs .NET Framework 4.5+ and runs on Windows 7 through Windows 11 with minimal CPU and RAM usage, so it will not affect your game performance.
The Developer
Meet the person who built NohBoard.
Eric “ThoNohT” Bataille
Eric is a software developer from the Netherlands who created NohBoard to solve his own need for a lightweight input visualizer. He built it in C# and chose to release it under the GPL license so anyone could use and modify it freely.
His development philosophy centers on keeping NohBoard simple and fast. Rather than adding bloat, he focused on making the core experience — seeing your inputs on screen — as smooth and configurable as possible. The project is hosted on GitHub where Eric accepts community feedback and contributions.
What NohBoard Means to Its Users
A tool that streamers and creators genuinely depend on.
NohBoard fills a specific gap that other tools do not cover as well. Streamers use it to show their audience which keys they are pressing during intense gaming moments. Speedrunners rely on it to prove their inputs are legitimate. Tutorial creators use it to help viewers follow along with keyboard shortcuts and mouse actions.
On Reddit and the OBS forums, NohBoard is regularly recommended whenever someone asks how to show keyboard inputs on stream. Its combination of free pricing, open-source transparency, low resource usage, and deep customization keeps users coming back. With over 1,100 GitHub stars and an active community creating and sharing custom layouts, NohBoard has carved out a loyal following among content creators.
