Mythex vs Google Antigravity

Antigravity is Google's agentic development platform, centred on a desktop IDE. Mythex is a browser workspace that builds, hosts and publishes the app.

The short answer

Choose Antigravity if you are a developer who wants several agents working in a desktop IDE on your own machine. Choose Mythex if you want the app hosted with a database and a public URL, and nothing to install.

Pick Mythex when

You do not want to install an IDE
You want hosting, a database and a public URL included
You want to describe the product rather than direct agents through code
You want phone apps made from your published app

Pick Google Antigravity when

You write code and want an agent-first IDE on macOS, Windows or Linux
You want to run several local agents in parallel
You want a CLI and SDK alongside the editor
You want Google's tooling, free for individual developers

Questions

Is Google Antigravity free?

Google says Antigravity is available at no charge for individual developers, with enterprise options for organisations. Hosting your app is a separate matter: you deploy it where you choose.

Do I need to code to use Antigravity?

It is an IDE, so it assumes you are comfortable with a codebase, even if agents write most of it. Mythex needs no setup: describe the app in chat, and the code editor is there only if you want it.

Antigravity vs Mythex for beginners?

For a beginner, Mythex is the shorter route to a live app, because the database and hosting are already there. For a developer who wants agents in a desktop editor, Antigravity is built for that.
