Google's agent-first development platform for building and shipping software with AI agents
A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.

Red-team and evaluate AI agents before they reach production
Adversarial evaluation of agents to surface unsafe, non-compliant or unreliable behaviour before they run against real users and real money.
Measure and track how much fine-tuning private models with LangTrain improves accuracy for your specific domain.
Verify that agent responses are repeatable and reliable enough for regulated workflows such as clinical, lending or claims decisions.
Evaluate agents that work across text, voice, vision and other modalities rather than text alone.

#1
Offers a more mature polished AI-native coding experience, but lacks Google's specific native multi-agent command center ecosystem.

Enables rapid full-stack app building and deployment entirely in the cloud, but offers less granular local agentic control.
Deeply reads entire codebases to execute complex multi-file tasks, though integrated as an IDE plugin rather than standalone suite.
Delivers robust spec-driven engineering and autonomous verification workflows, though configured differently than Google's developer platform.
Cognition's autonomous software engineer that ships real pull requests
Free / Open-sourceOpen-source development environment running multiple CLI coding agents in isolated git worktrees, but requires manual setup.

Provides a seamless AI-driven IDE workflow with strong multi-file editing, but offers less specialized multi-agent orchestration control.
