With Decode you can view as many app screens as you need. Enabling you to review your working app as easily as reviewing a Figma file, but with Claude Code immediately apply your suggestions. Get early access: decode.dev/

Inspiring UX! Kinda weird that you can’t just click a button to “Apply changes” and I’d love to see comments remain on screen until sent to the agent

Good thinking! Yes totally ok comments being left in place. Thats more how I envision it. Making a convenient, ok now send what I queued absolutely needs to be added to.

Amazing! This looks like you've built your own web browser with Claude attached. Does the browser forward logs and screenshots to Claude as well?

We’ll be adding all these. Basically let Claude Code query every part of your running app that it can and control it too

awesome, congrats on the launch! signed up! being able to organize code snippets into a whiteboard, where I can easily zoom in & out of files / functions would be awesome

Thanks! We actually removed all viewing of code now to see how far we could take just focusing reviewing and understanding the product not the code itself.

looks pretty cool. are the different pages just dom snapshots or such? or actual open windows/tabs? just trying to imagine what the memory footprint is like with Decode open with an an app with lots of screens.

They are actual open tabs. Definitely could get crazy at some point. We’ll need to add some tricks to help with that.

How do you mean? There’re no real time APIs used in these videos.

We aren’t charging yet. Need some time to experiment with pricing models.

@seflless this flips the script on solo prototyping claude iterating in real-time like a ghost dev over your shoulder. ever thought about layering in voice commands for hands-free tweaks during late-night sessions? what's the wildest ux pivot you've seen it nail so far?
1
Works in early morning sessions too! Heck yeah on voice controls, it will fit very well.

@grok are tehre any open source tools with the same capabilities?
2
You wouldn't pay for useful software? -- says founder who loves open source tools and mostly uses them. All jokes aside, I haven't found anything great on this front that was open-sourced. Send them my way if you find them.
