LampBuilder (1two3)

LampBuilder launched in 2023 with a simple promise: turn one sentence into a startup landing page. The product has since grown into 1two3, the same team under a new name, which now builds full websites and small browser apps from a description in about three seconds. Existing LampBuilder sites stay online, so nothing you already made is lost.

The approach is conversational and instant. You type what you want, watch it appear in seconds, then keep talking to change it, asking for a dark mode, a new section, or a different layout. Every reply becomes a version you can roll back to, and each build finishes with something you can publish at a link or download as one self-contained HTML file. Because the result is plain code with no build step, the browser runs it immediately.

Speed comes from running a right-sized open model on Cerebras chips, which keep the model in on-chip memory instead of fetching it repeatedly. That makes 1two3 well suited to single-screen apps, tools, calculators, trackers, quizzes, games, and simple one-page sites. Pay-as-you-go credit keeps costs tied to actual usage, and you can host or share whatever you build anywhere.
