A multiplayer vibecoding tool where you talk and point with your mouse, and every change lands in seconds. Has limited credits to try it out, and you can BYO API keys to unlock more usage.
While we're all getting more productive with agentic coding tools, I haven't yet seen a compelling multiplayer or collaborative coding experience. Sure, there are tools that make it easy to hand off work or fork a session, but there aren't tools where you can get into collaborative flow the way we used to in Figma, for example, or in front of a physical whiteboard.
I wanted to try to recreate that experience, so I built a coding harness that lives in the browser and is voice-driven. It uses preemptive turn detection to kick off builds and fast models with the reasoning turned off to make sure each change lands in seconds, so you can see the product being built before your eyes.
The thing I'm most interested to learn is whether it's fun or useful to use this with someone else. Pop in and start prototyping your latest idea, and send a link to a friend and let me know how it goes!
Tried it today. Typing worked, but voice only understood English, and my English is not great. For non-English speakers the talk part is the main barrier. Added a request for spoken language support.
Really cool! I wonder if we could get an existing url, and load it in, so then we can tweak on top of that, instead of starting from scratch.
