what is collabio fr?

Collabio is an online whiteboard where multiple people can draw and collaborate together in real time. Think of it like Google Docs, but for sketching and brainstorming visually instead of writing text. When one person draws a line or adds a shape, everyone else watching the same board sees it appear instantly. The app lets you do what you'd do on a physical whiteboard: draw freehand lines, create circles and rectangles, erase mistakes, and even undo or redo your last few actions. Beyond basic drawing, you can drop images onto the canvas, move things around once you've placed them, change the background color, chat with other collaborators, and save your finished work. The system also tracks everyone's mouse cursors in real time, so you can see where others are pointing or about to draw. This would be useful for a lot of scenarios. A design team could sketch wireframes together without being in the same room. Teachers could illustrate concepts during online classes. A group planning a project could brainstorm ideas visually. Engineers could diagram system architecture. Product managers could map out user flows. It's especially handy during remote meetings when talking alone isn't enough, you need to show what you mean. The project is built with modern web tools: Next.JS for the interface, Socket.IO to handle the real-time synchronization (so everyone's canvas stays in sync), and TailwindCSS for styling. The code is open source, so if you want to run it yourself or tweak it, you can clone it and set it up as a standard Next.JS application. There's also a live demo running online if you want to try it without installing anything.
