Origin Story

By Vjeux (Christopher Chedeau)

The Problem

Needed a quick way to sketch diagrams that looked hand-drawn and informal, not the rigid boxes of traditional diagramming tools.

Building It

Started as a weekend project in January 2020. Went viral almost immediately. Grew to millions of users. Open sourced from day one.

First Customer

The product went viral on Twitter within days of launch. Developers loved the hand-drawn aesthetic for architecture diagrams.

What It Means

The best tools are often the simplest. A whiteboard with hand-drawn lines became one of the most beloved developer tools.

The Dream

To be the default way people sketch and explain ideas visually.
