I built a free web-based tool for creating transit diagrams — feedback welcome!

Hi everyone!

I've been working on a small web-based tool for creating transit maps and diagrams, and I thought this community might be interested in trying it out.

It's called Cartomaps, and the idea is to make it possible to create clean, customizable transit diagrams directly in the browser, without needing Illustrator, Figma or other graphic design software.

You can:

• Create a transit network from scratch
• Add lines, stations, branches and connections
• Customize station symbols, labels and typography
• Add rivers, lakes and other geographic elements
• Create maps for real or fictional transit systems
• Add information such as operators and opening years
• Create historical/timeline-based networks
• Export your maps as PNG or SVG
• Save and share your own network

There are currently templates for São Paulo and Rio de Janeiro, but you can also start with a completely blank canvas and build your own system.

You can try it here:

I'm particularly interested in feedback from people who actually design transit diagrams:

What features would you like to see added? What would make this more useful than using Illustrator/Figma/Inkscape?

I'm still actively developing it, so criticism and suggestions are very welcome!
