Google Antigravity

Google Antigravity is Google's agent-first coding platform. It launched in November 2025, and Antigravity 2.0, announced at Google I/O in May 2026, added a desktop app for running and managing background agents alongside the Antigravity IDE, a command-line interface (the agy command) and a Python SDK. The desktop app runs on macOS, Windows and Linux, and since August 2026 Antigravity extensions bring the agent into Visual Studio Code, Visual Studio, JetBrains IDEs, Zed and Xcode, with an Eclipse extension in public preview.

Agents plan and carry out multi-step work across the editor, the terminal and a Chrome browser, and custom subagents, hooks, scheduled tasks, a preview of agent teams and remote control from a browser extend that. Instead of raw tool logs, agents produce Artifacts such as task lists, implementation plans, walkthroughs, screenshots and browser recordings, and developers can comment on an Artifact while the agent keeps working. Under the default permission preset, the agent edits files in the workspace and runs terminal commands inside a sandbox without prompting, and asks before running commands outside the sandbox, browsing the web or calling MCP tools.

Antigravity connects to MCP servers, and its MCP Store lists more than 70, including GitHub, GitLab, Linear, Atlassian, Figma, Supabase, BigQuery and Stripe. The Python SDK connects MCP servers alongside built-in tools, and developers moving from Gemini CLI can import its extensions and settings into the Antigravity CLI. Enterprise teams sign in with Gemini Enterprise or a Google Cloud project, where sessions run under the Google Cloud Terms of Service.

Individual use is free, with unlimited Tab completions and command requests under weekly rate limits. Google AI Pro, at $19.99 per month, and Google AI Ultra, from $99.99 per month, raise the rate limits, refresh quota every five hours up to a weekly limit, and let users spend AI credits once the baseline quota runs out. Those plans are sold as Google AI subscriptions, priced in US dollars. Organizations buy access through Google Cloud, either on Gemini Enterprise Standard or Plus plans from $30 per seat per month or on a pay-as-you-go plan with no seat fee and consumption-based pricing.

Model choice depends on the plan. In late October 2026 the free plan and Google AI Plus offered Gemini 3.8 Flash, Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS 120B. Paid Google AI Pro and Ultra added Gemini 4 Argon and moved Claude to Sonnet 5.5 and Opus 5.5. Enterprise offered Gemini 4 Argon, Gemini 3.8, 3.7 and 3.6 Flash, Gemini 3.1 Pro and the Claude 5.5 models, without GPT-OSS. Bring-your-own API keys are not supported, and signing in to Antigravity from third-party tools breaks its terms. Antigravity is available to personal Google accounts held by people aged 18 or over in approved countries.

Antigravity suits developers who want to run several agents in parallel and review their work through Artifacts, from a desktop app, the terminal or their existing IDE. Developers who want an open-source agent that runs on their own model keys should also look at OpenCode or Cline, and teams whose work runs through GitHub pull requests should look at GitHub Copilot. Developers who work in JetBrains IDEs and want to run and govern several coding agents there should look at JetBrains Air.

Current state Q4 2026: Gemini 4 Argon reached the Antigravity app and CLI for Google AI Pro and Ultra subscribers on October 13, 2026, and the IDE extensions on October 19. October releases also added Automations and a built-in browser to the desktop app. Earlier, Antigravity added custom agents and Gemini 3.7 Flash in August 2026, IDE extensions and Gemini Enterprise availability on August 20, remote control from a browser the next day, and Gemini 3.8 Flash in September 2026. Individual use falls under terms that let Google use interactions to improve its products and machine learning technologies, with human reviewers able to see them, and a setting to opt out. Sessions under Gemini Enterprise follow the Google Cloud terms, and Google states that data there is not used to train foundation models. Google Cloud lists Antigravity in Gemini Enterprise among its HIPAA-covered services.
