Hey Product Hunt! 👋 I’m Alberto, the maker of Markasso.

This started as a small experiment: a whiteboard built with vanilla TypeScript and Canvas, keeping the core free of dependencies. It grew into something I wanted to share.

Open it and start drawing. No account, no setup. You can sketch ideas, build architecture diagrams, connect shapes, collaborate live, and export your work.

For those working with AI agents, there’s also an MCP server: your agent can draw and edit diagrams alongside you.

I’d love to hear what feels useful, what feels awkward, and what you’d use it for. If you try it, let me know where you get stuck.

A special thanks to Lorenzo Cataldi for contributing to Markasso and helping make it better.

Thanks for taking a look!
