Google Antigravity
Worth trying for developers who want Google's own agent stack across a desktop manager, terminal and IDE, especially anyone who relied on Gemini CLI and has to move. The free tier is enough to evaluate it, but heavy daily use points to a Google AI or enterprise plan. Teams standardized on another vendor's agent have little reason to switch yet.
Pros
- Free individual tier that includes the CLI and the IDE
- Four surfaces share one agent harness: desktop app, CLI, SDK and IDE
- Business route through Google Cloud with spend caps and admin controls
- Python SDK for building custom agents
Cons
- Free tier uses weekly rate limits that are not quantified
- Pro and Ultra pricing is not shown on the Antigravity site
- Gemini CLI users were given a short migration window when it was retired
