Post Description

Hi there. I was looking for a pastebin-like instant solution for online meetings — a shared whiteboard with real-time sync. Of course there are Excalidraw and tldraw, BUT they require signup and are overgrown with features I don't need. So I just built cnvs.app — instant sharing, no signup, real-time sync with all the essentials: drawing, writing, and pasting images. All in one day. On day two I added sticky notes, full mobile support, and Mermaid diagrams (cool thing — try pasting some Mermaid syntax there!) and deployed to Cloudflare so everyone can use it for free.

Be creative. Have fun :)

Please hack my C webserver (it's a collaborative whiteboard)

This is basically an invitation to tinker: a small C-based webserver serving a shared HTML5 canvas so you can study or extend the networking and drawing logic instead of hiding it behind Node frameworks. The UI is functional but crude — no polish, no UX niceties — which makes it useful as a learning playground but not as a competitor to mature collaborative whiteboards. If you want to add auth, persistence, or smoother sync logic, the repo looks like a friendly starting point.
