Google Antigravity

by Google

JetBrains Air

by JetBrains

Pros

• ✓Runs several agents in parallel and reports through Artifacts such as plans, walkthroughs, screenshots and browser recordings, which developers can comment on while the agent keeps working.
• ✓Works from a desktop agent manager, a standalone IDE, a CLI, a Python SDK, and extensions for Visual Studio Code, Visual Studio, JetBrains IDEs, Zed and Xcode.
• ✓Google Antigravity's free individual tier includes Gemini 3.8 Flash, Gemini 3.1 Pro, Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b, with unlimited Tab completions.
• ✓Connects to MCP servers through an MCP Store listing more than 50, and runs terminal commands in a sandbox under a configurable permission system.

Limitations

• –Paid tiers are Google AI subscriptions, Pro at $19.99 per month and Ultra from $99.99, with usage set by quota refreshes and weekly limits rather than a published request count.
• –Bring-your-own API keys are not supported, and the Claude and GPT-OSS models are not available on the Enterprise plan.
• –On individual plans Google may use interactions to improve its products and models, and human reviewers may see them, unless the user opts out in settings.
• –Available to personal Google accounts for people aged 18 or over in approved countries, and enterprise sign-in for JetBrains, Zed and Xcode is in preview.

Pros

• ✓Runs several coding agents in parallel inside JetBrains IDEs, including Junie, Codex, Claude Agent, GitHub Copilot and any ACP-compatible agent, with no lock-in to one vendor.
• ✓Agents get the IDE's code intelligence and built-in tools, and every change opens as an IDE diff that can be reviewed and commented on line by line.
• ✓Air Governance Basic is free for JetBrains business customers and adds centralized billing, spending limits, SSO and AI analytics across agents and providers.

Limitations

• –Air in IDEs and Air Teams are both in early access, mobile access is listed as coming soon, and cloud runs are still rolling out to remaining customers.
• –Cloud runs currently require a JetBrains AI subscription, and usage beyond the free Junie Lite runs is paid in AI credits or through the developer's own provider keys.
• –Model and agent controls, centralized MCP management and managed provider keys need Air Governance Business at $20 per seat per month, and audit logs and SCIM need Enterprise.
