cto.new uses Northflank’s microVMs to scale secure sandboxes without sacrificing speed or cost

cto.new is a free AI coding platform that provides access to advanced models from Claude and OpenAI, aiming to democratize coding by enhancing developers' capabilities through AI. Initially, they faced challenges with their infrastructure, which involved using Firecracker microVMs on EC2 instances, leading to high costs and scaling difficulties. They switched to Northflank's microVM platform, which offers per-second billing and API-driven provisioning, allowing them to manage thousands of daily container deployments efficiently and economically. This transition enabled them to handle unexpected traffic spikes during their launch week, during which over 30,000 developers signed up, and maintain smooth performance while focusing on product development rather than infrastructure management. Northflank's flexibility and support for various integrations further assist cto.new in evolving their platform's capabilities without significant architectural changes, making it a strategic partner for future growth.
