Create Diagrams That Look Like Hand-drawn

Get started with Excalidraw

Janne Kemppainen |

Yesterday I heard about an open source project called Excalidraw which is an app that lets you draw diagrams that look like they were done by hand. Its development started on January 1st, and now 25 days later it has already had 44 contributors and 2.5k stars on GitHub.

Even though it is still quite new and actively under development the results are already quite impressive so I felt the need to piece together a small “tutorial” to show you what it can be used for. If you want to create cool looking flow charts or other diagrams this might be all you need!
