Liminal: A Browser-Based IDE for Laravel Powered by WebAssembly

Liminal is a browser-based IDE that runs PHP 8.4 via WebAssembly, enabling full Laravel development without any local installation or server setup. It includes a code editor with syntax highlighting (CodeMirror 6), a preview pane with Tailwind CSS v4, an Artisan terminal, and an OpenAI-powered AI agent. Notable features include shareable URLs that encode file state, GitHub import, zip export, and local folder sync via the File System Access API. Limitations include no external network access from PHP, SQLite-only database support, a fixed vendor directory, and slower-than-native performance. The project is built with Vue 3, TypeScript, Vite, and Tailwind CSS v4.
