Our first offline app just shipped — and no one wrote a line of code

This week, the first offline-first PWA went live on WebsitePublisher.ai.

A travel blog that works without internet. Write posts on a plane, attach photos, and everything syncs the moment you reconnect. Service Worker, IndexedDB, sync queue — the full stack.

The twist: it was built entirely through conversation with an AI assistant. No IDE, no terminal, no deploy pipeline.

How that works

WebsitePublisher.ai exposes 92 integrations as building blocks via MCP (Model Context Protocol). Any AI assistant — ChatGPT, Claude, Cursor, Windsurf, Copilot, Gemini, Grok, Mistral — connects to the same runtime and assembles these blocks into working applications.
