Congrats on the launch! As someone who spends a lot of time giving design feedback and talking through UI changes, this feels incredibly useful. Being able to mock things up live in the browser without switching tools sounds like a real workflow upgrade.

@nataliemac7 thank you! yep, skipping all the switching is what makes it feel snappy and smooth :)

This is so good! The simplicity is honestly the best part - no fluff, just open and use.

I’m dreaming of something like this but for mobile screens - to clear up so much miscommunication about changes

Big fan already. Congrats on the launch! 🚀

Aleksandr Heinlaid

@yura_pogosyan really appreciate it! mobile support is a great idea - we’re thinking in that direction too.

Eadin

Amazing, installed! are users allowed to change the typeface?

Aleksandr Heinlaid

@wang_yiting thank you! not yet, but custom fonts are definitely something we’re considering

Yong Woo Shin

The smartest way to communicate with developers!

Drawing a wireframe should have been easy like this.

Congratulations, @aleksandr_heinlaid@lembit_hunt!
