Show HN: OpenGravity – A zero-install, BYOK vanilla JS clone of Antigravity

The zero-install agentic workspace. An experimental, lightweight, BYOK (Bring Your Own Key) recreation of the Google Antigravity UI. OpenGravity provides a browser-based, reasoning-enabled IDE with a live xterm.js terminal powered by the WebContainer API. It features direct local file system sync and a proactive autonomous agent capable of orchestrating basic software engineering tasks, running shell commands, and editing files in real-time. It’s currently a work-in-progress though. It works for basic coding tasks, but consider this the "Alpha" version. Built in pure HTML/CSS/JS for maximum speed and zero installation. The agent can proactively initialize projects, install dependencies using pnpm , and build complete applications while you watch. I’m currently heads-down in my studies, so I’m handing the baton to the community. The UI looks great and the basic logic is there, but it needs "pro" features to truly beat the original. I want people to take this and make it usable for the average person. Specifically: I'm balancing this with my GCSEs, so I will be reviewing and merging PRs every Sunday evening.
