Kernel, a Y Combinator startup providing cloud browser infrastructure for AI agents, runs its entire customer-facing stack on Railway for just $444/month. Co-founder Rafael Garcia, who previously watched his company Clever build a six-person AWS infrastructure team, chose Railway from day one to avoid repeating that mistake. Railway handles Kernel's API, dashboard, websocket connections (Chrome DevTools Protocol), and Temporal workers, enabling zero-downtime deployments and easy scaling with a few clicks. The result: growth from zero to 1,000+ customers in seven months with no dedicated infrastructure engineers.
