Google Antigravity

Why 4: its agents work across the editor, terminal and browser in parallel and report back with task lists and recordings, and can run scheduled background tasks; you review afterwards.

What it does. Antigravity launched in November 2025 alongside Gemini 3 as a code editor with a separate manager for running several agents at once; they work across the editor, terminal and browser and report back with task lists, screenshots and recordings. Antigravity 2.0, at I/O in May 2026, added a desktop app that can schedule background tasks, a command-line tool that replaces Gemini CLI, and an SDK.

Where it falls short. Agents that browse the web and run shell commands can be steered by what they read, and Google lists browser-agent data exfiltration through prompt injection as a known issue. Its usage limits are tied to Google's consumer subscription tiers.
