In 2025, developing a full-stack application is simplified with app.build, an open-source AI agent that generates, tests, and deploys web apps directly from your terminal by interpreting user prompts. Created by Neon and utilizing Koyeb's serverless infrastructure, app.build ensures apps are built with secure, isolated environments through sandboxed microVMs, allowing for efficient scaling and resource management. The platform leverages a familiar tech stack, including Fastify, Drizzle, React, and Vite, and employs AI models like Claude and Gemini for code generation. With built-in CI/CD, app.build provides seamless deployments, automatic domain provisioning, and rapid scaling to zero for idle applications. This initiative aims to bridge the gap between AI-generated code and functional software, promoting a community of developers who can iterate on projects stored in GitHub repositories, and is poised to support various AI models in the future.
