Google Antigravity Rolls Out Browser Use for Its Coding Agent
Browser use has been rolling out in Antigravity, closing the loop between researching, writing code, and verifying it live. You choose what to log into, downloads pause until you approve them, and the agent can use the browser to run multiple tasks at once. Give it a try today.
Context
Letting a coding agent research, build and check its work in a live browser closes a gap that usually needs a human.
Antigravity is Google's agent based coding environment. On Nov 10 it added /swarm for running teams of agents in parallel, alongside the Gemini 4 Carbon launch.
Deep dive
Google Antigravity posted that browser use has been rolling out in the product, describing it as closing the loop between researching, writing code and verifying it live.
According to the post, users choose which sites the agent can log into, downloads pause until the user approves them, and the agent can use the browser to run multiple tasks at once. Google invited users to try it the same day.
The post does not say which plans include the feature, whether it works in both the desktop app and the command line tool, or which models power it. It also gives no figures on reliability.
Browser access lets a coding agent open documentation, test a web app it just built and check that pages render correctly, tasks that developers would otherwise do by hand. The approval step for downloads and the user controlled logins are safety limits meant to stop an agent from taking unwanted actions on a user's accounts. The update follows the /swarm feature Antigravity added a day earlier.
What to expect next
Expect developers to compare Antigravity's browser agent with similar features in Cursor, OpenAI Codex and Claude, especially on how well it tests web apps and how often it needs human approval. Google may publish documentation on permissions and limits. Security researchers will also likely probe how the agent handles malicious web pages, a known risk for any agent that browses on its own.
