App.build is transitioning from a command-line interface to a more accessible web interface that allows users to build and deploy React, Laravel, or FastAPI applications without configuration. This open-source AI agent, initially designed as a reference implementation for agent builders, supports multiple tech stacks including React with tRPC, Laravel (PHP), and FastAPI with NiceGUI. With the discontinuation of the managed app.build version, users can still access the source code for reference and implementation examples. The new web UI aims to enhance user experience by offering features like app previews and supporting multiple deployment platforms, while the CLI will soon be deprecated due to maintenance constraints. The team is focused on expanding tech stack options and deployment platforms, welcoming feedback and contributions via GitHub or Discord.
