Fuck baldamiq slow ahh goofball laggy software!
Draw.IO is the best and lightweight and now i found out it can do mockups too! Using it

draw io is great honestly yeah

You can import my Draw.io FontAwesome library for flexible icons in your draw.io mockups: https://github.com/webketje/...

Also draw.io can do basic prototyping interactivity with layers and links and json and tags + it has a Confluence integration (if you're using Atlassian stack)

I love https://excalidraw.com/

It's open source and beautiful

@MammaNeedHummus peeked into the comments just to see if anyone has mentioned it...it's amazing

I use Lunacy... It is decent enough
