Generate complete, working web apps that run entirely in the browser — no server, no build step, no backend required. Produces real HTML/CSS/JS files you can open immediately. Covers games, tools, dashboards, forms, calculators, offline PWAs, and more. ## What's included - **Single-file app generation** — describe what you want, get a complete HTML file you can save + double-click - **Multi-file mode** — bigger apps with separated HTML/CSS/JS + downloadable as zip - **Browser API reference** — what's available without npm (LocalStorage, IndexedDB, Fetch, Web Audio, Canvas, WebGL, Service Workers, etc.) - **Offline PWA mode** — generates manifest.json + service worker for installable apps - **Skill-level adaptation** — beginner-friendly commented code vs. terse production-ready code (you pick) - **Blob download packaging** — apps that work fully offline including user-uploaded files - **Template gallery** — games (Tetris, Snake, Pong), tools (image editor, color picker, JSON formatter), dashboards (revenue chart, todo list), calculators (mortgage, BMI, tip) ## Limitations - **No backend means no shared state across users** — if you need multi-user / auth / persistent server-side data, this isn't your tool (use Vite + a real backend) - **Browser-only APIs** — no filesystem access beyond what File API allows, no native OS integration - **Bundle size limits** — single-file apps cap around 1-2MB for usability - **No automatic updates** — once you download the file, it's frozen; manual re-generation for changes - **CORS limits some 3rd-party API integration** — covers what works in-browser ## Best fit Builders prototyping ideas fast, teachers building lesson tools, hobbyists making personal utilities, indie devs shipping browser-extension-friendly tools. Especially valuable for people frustrated with the modern web stack overhead (npm / build / deploy) when the actual idea is a 200-line script.
