AntigravityJulesChoose Google Antigravity if you are developers who want to try the most agentic IDE experience available today. Choose Jules if you are developers who want to queue up fixes and features and review PRs later.
In our editorial scoring, Google Antigravity leads in 3 of six categories (output quality, autonomy and speed), while Jules leads in 2 (reliability and ease of use). On price, Google Antigravity runs free public preview and is proprietary; Jules runs free tier / google ai plans and is proprietary.
Antigravity is Google's agentic development platform, launched alongside Gemini 3: a VS Code-style IDE where an agent manager dispatches agents that work across the editor, terminal, and a Chrome browser they control — producing verifiable artifacts (plans, screenshots, browser recordings) as they go. The free public preview and Gemini 3 Pro quality made it an instant heavyweight, but it's still early: capacity limits, preview rough edges, and early prompt-injection concerns around the browser-control surface mean production teams should keep a human on the loop.
Jules is Google's asynchronous coding agent, powered by Gemini. Unlike interactive agents, you assign it tasks — bug fixes, dependency bumps, small features — and it clones your repo into a cloud VM, writes and tests the change, and comes back with a pull request and an audio changelog summary. The free tier makes it an easy add to any workflow, but the async model means it suits queued, well-defined tasks rather than tight pair-programming loops, and turnaround depends on task queue and complexity.
