Who should switch from Google Antigravity?
Consider an alternative if any of these apply:
- You want models outside Google's ecosystem
- Paid limits tied to Google AI subscription tiers don't suit you
- Naming changes (Gemini CLI → Antigravity CLI) broke your setup
Stay on Google Antigravity if you want a generous free agent tier and tight Gemini and Google Cloud integration. Its strengths: generous free individual tier; tight integration with gemini models and google cloud; ide and cli share one quota.
The 5 best Google Antigravity alternatives
1. Cursor
Why switch: Multi-model AI editor with Tab completion and Agent; free Hobby tier.
Best for: Developers who want AI woven into everyday editing, with an agent one keystroke away. Watch out: Usage-based limits can be confusing; heavy agent use costs more than $20.

2. Kiro
Why switch: Spec-driven agentic IDE from AWS with a free tier.
Best for: Teams that want structured, spec-first agent development — especially AWS shops. Watch out: Credit-based limits.

3. Jules
Why switch: Google's async GitHub agent — free plan with 15 tasks a day — if you want to stay on Gemini.
Best for: Developers who want to offload chores (dependency bumps, tests, bug fixes) to a background agent for free. Watch out: Gemini models only.

4. Claude Code
Why switch: Terminal agent with top tracked Terminal-Bench 4.0 scores, on Claude models.
Best for: Developers who are comfortable in the terminal and want an agent that can own multi-step tasks end to end. Watch out: Claude models only — no OpenAI/Gemini option.

5. Cline
Why switch: Free open-source VS Code agent where you can point at Gemini or any other model with your own key.
Best for: VS Code users who want an autonomous agent with full control over models and spend. Watch out: Token costs can climb on big tasks.

How to choose
- Decide where the AI should work — terminal, editor, browser or GitHub. That rules out half the list.
- Check model lock-in. Google Antigravity uses Google Gemini models (plus a selection of other agent models — check site). Bring-your-own-key tools let you change models later.
- Run one real task from your backlog in your top two picks and compare the diffs, not the marketing. Our benchmarks page shows independent agent scores where they exist.
