# Antigravity (Google) > Antigravity is Google's answer to Cursor. The differentiator: Gemini's 2M-token context window means the IDE can hold the entire repo in its working memory. Best fit when your codebase is big and your platform is already Google. Source: https://aistack.sh/stack/ship-code-antigravity Category: Code · Workflow Level: Intermediate Last verified by a human: 2026-05-05 ## The tools ### Antigravity — Plan + write + iterate - Pricing: Free · $19.99/mo Google AI Pro · $99.99/mo AI Ultra 5x · $199.99/mo AI Ultra 20x - Site: https://antigravity.google - Why this one: IDE-shaped surface backed by Gemini. Built-in planner agent + editor agent + review pass. Best when the repo is large enough that smaller-context IDEs lose the thread. - Swap in instead: Cursor, Claude Code, Codex - More: https://aistack.sh/tool/antigravity ### Claude — Cross-vendor diff review - Pricing: Free · $20/mo Pro · $100/mo Max 5x · $200/mo Max 20x · Sonnet API $2/$10 per M tokens (input/output) - Site: https://claude.ai - Why this one: Antigravity's built-in review pass uses Gemini — same model that wrote the code. A second opinion from Claude (different lineage, different priors) catches what Gemini's self-review wouldn't. Paste the diff + ticket; ask for a structured review. - Swap in instead: CodeRabbit - More: https://aistack.sh/tool/claude ## Monthly cost ### $0/mo — Solo OSS, preview tier (small) - Antigravity: Free preview - Claude: Free tier ### $40/mo — Solo dev, full IDE features (medium) - Antigravity: ~$20 (post-GA est.) - Claude: $20 Pro ### $200/mo — Team on Google Cloud (heavy) - Antigravity: ~$100 (5 seats) - Claude: $100 (5× $20 Pro) ## Workflow ### 1. Open the repo in Antigravity (Antigravity) Same as VS Code. The first index pass takes a minute or two for a large repo; subsequent prompts use the cached context. ### 2. Hand the planner the ticket (Antigravity) Antigravity's planner agent reads the whole repo. Generates a plan that respects existing patterns. ### 3. Editor agent applies the plan (Antigravity) Multi-file edits with diffs you accept hunk-by-hunk. The 2M context means it rarely loses the thread mid-refactor. ### 4. Cross-vendor review with Claude (Claude) Push the branch and grab the diff. Paste it into Claude with the ticket; ask for a structured review. The cross-vendor angle catches Gemini-flavored blind spots before a human reviewer does. ### 5. Apply review fixes (Antigravity) Bounce Claude's findings back to Antigravity's editor agent. The whole-repo context makes review-fix patches especially clean. ## What it produced **Backend team on GCP** Ran a 4-week refactor (replacing an internal pubsub layer) with Antigravity as the primary IDE. The 2M-context kept the agent on-track across ~30 files; previous attempt with a smaller-context IDE drifted by file 12. ## Pitfalls - **Preview-tier limits** — Antigravity is in preview. Quotas, model availability, and pricing may shift before GA. Don't bet a deadline on a specific feature without a fallback IDE. - **Whole-repo context can leak secrets** — If your repo has committed .env or service-account keys, the agent will happily quote them in chat. Audit git history before pointing the agent at the repo. ## Verifiable artifacts - [booststash — three weeks of daily Antigravity use](https://www.booststash.com/google-antigravity-review-i-tested-googles-ai-ide-for-3-weeks/) — Independent reviewer, not a Google employee. Three weeks of daily-driver use with screenshots of real IDE output and called-out bugs. Antigravity is preview-tier so most write-ups are still vendor-authored — this one isn't. ## Recent changes affecting this stack - **Antigravity 2.13.0 adds Documents section and virtualized file viewer** (2026-09-09, release) — Version 2.13.0 introduces a new Documents section in the sidebar for external files and a virtualized viewer for large code files with syntax highlighting and inline comments.
