What is porta?
Porta gives you a browser-based way to reach Google's Antigravity agent from other devices. It runs a local proxy that connects to the Antigravity language server and a web front end you can install as a PWA. The stack needs Node.js 22 or newer and pnpm 10 or newer. Data moves over WebSocket as structured LSP messages, so bandwidth stays tiny and latency is low. The UI works well on phones and tablets. If you want access from outside your LAN, the docs explain how to wire it up with Cloudflare Tunnel, Pages, and Zero Trust. You must already have Antigravity running; Porta does not add a code editor or terminal. Licensed MIT.
