jambuild
1 commentjambuild is a multiplayer vibecoding tool where you build web apps by talking and pointing with your mouse, and every change lands in seconds. Say what you want to build, point at what you mean by moving your cursor over the page, and whatever you hover lights up for everyone in the session. Click anything and say what should happen to it, and the change appears in under ten seconds. Send a link and build with one other person: you both talk, you both point, and it is one page. The coding harness lives in the browser and is voice-driven with preemptive turn detection to kick off builds and fast models with reasoning turned off, so you can see the product being built before your eyes. Has limited free credits to try it out, and you can bring your own API keys to unlock more usage. Built by Rajiv Ayyangar.

The collaborative coding tools we have now make it easy to hand off work or fork a session, but they do not recreate the flow you get when you are building in front of a physical whiteboard or paired up in Figma. jambuild is the attempt to bring that collaborative feel into coding: you talk, you point, and every change lands in seconds so you can see the product being built before your eyes.
The part that made me look twice was the preemptive turn detection. Most voice-driven coding tools wait for you to finish talking, then send the whole block to a model. jambuild kicks off builds before you finish speaking, so the change lands while you are still thinking about what to say next. That is the difference between a tool you narrate to and a tool you build with. I have not tested it with someone else yet. The first thing I would check is whether the multiplayer part feels like collaborative flow when both people are talking and pointing at once, or whether it becomes chaotic and you end up taking turns anyway.
