In their words

Floot is the layer where vibecoded software runs. SaaS is dead. Hundreds of millions of people already spend their day in Claude or ChatGPT - and increasingly, when they need an app, they won't buy one. They'll describe it, and it will exist. We're building the infrastructure that makes that real. When Claude creates an app, it needs somewhere for that app to live: a backend, a database, hosting, a domain, the ability to scale, various services, maybe even to be able to work as a mobile app. Floot is that place - a full stack purpose-built for AI to operate, from a specialized framework that defines how AI writes and runs code, down to scalable hosting on AWS. This means you can now build and ship real apps directly inside Claude and ChatGPT. Connect Floot, and the model you already pay for writes and debugs the code, shows a live preview, and publishes to your own domain. No need to wire up git, vercel, supabase and a dozen other providers. And no AI credits - every message runs on the subscription you already have, because we charge for the platform, not for a token markup. We built Floot this way because we've watched the model layer commoditize - every serious builder writes good code now, including us. The lasting value isn't another agent between you and the model. It's the layer underneath, from wherever people already are. We're building Floot to be the home for all operation software, for the decades where most new software on earth is written by AI. ✨ Try it: floot.com

FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. FoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
