Solar lets small teams collaborate with AI agents to build and deploy production apps in minutes. Like Figma, but no mockups — just real software with live data and backend functionality, built by our full-stack AI agent, powered by your imagination.

I'm John, CTO at Lumenary. Today, we’re so excited to launch Solar: an infinite canvas for vibe-coding production apps. My co-founders—Vivek Hazari, Daniel DiPietro, and Ziray Hao—and I built Solar during Y Combinator after living in a hospital for nearly two months.

What began as an internal tool to help healthcare executives improve care delivery with AI has evolved into a platform that domain experts across industries use daily.

During our first beta, teams built things we didn't think were possible, including:

📈 Trading bot armies that execute complex market strategies on the stock market. https://stocks.by.solar - deep-learning training environment.

🛰 Graduate thesis research papers implemented end-to-end in minutes. https://analysis.by.solar - satellite imagery analysis.

🎮 Full multiplayer game engines from scratch. https://craft.by.solar - you already know.
