ASCII Diagram, offline, Linux, FLOSS

cross-posted from: https://programming.dev/post/32373635

Hi,

I'm looking for a soft to create ASCII diagram like (or better) https://asciiflow.com/

ideally:

• FLOSS
• for linux
• offline
• no javascript.

I've found a candidate ascii-draw and it's write in Python ❤️ 🐍, but it's only available as flatpack.. :/
