Google Antigravity vs Jules: Which Google Coding Agent Do You Need?

Google Ships Two Coding Agents. Here Is the Difference.

The confusion is understandable: both are Google products, both are agentic, and both are bundled into the same Google AI subscriptions. The split is about where the work happens. Antigravity is a development platform you sit inside: an editor plus a Manager surface where you spawn agents, watch them use the terminal and browser, and comment on the Artifacts they produce. Jules is a service you delegate to: it takes a GitHub repo and a prompt, works in an isolated cloud VM, and returns a finished pull request with a self-review already done.

When Each One Fits

• You are actively building: Antigravity. It is the Cursor-style daily driver, with parallel agents and browser verification of frontend work.
• You are clearing a backlog: Jules. Label a GitHub issue with jules and a pull request shows up, with failing CI runs fixed automatically.
• You want scheduled maintenance: both offer it, but Jules's recurring tasks against a repo are simpler to set and forget.
• You need models other than Gemini: only Antigravity, which offers Claude and GPT-OSS options alongside Gemini 3.x.

Same Subscription, Different Maturity

Both ride the Google AI plans: free entry points, more capacity at $19.99/mo Pro, and top limits on the $99.99/mo Ultra tier. Jules is the steadier product, generally available since August 2025 with a stable task-based pricing model. Antigravity is the more ambitious one and still officially in preview, with 2026 marked by quota turbulence and a forced migration as it absorbed the old Gemini CLI. They are complements rather than rivals, and Google positions them that way: many developers run Antigravity as the workbench and Jules as the background crew.
