Updated April 29, 2026
Overview
Google Antigravity is Google's agentic development platform, with an agent-first IDE, a terminal CLI, and Antigravity 2.0 for running multiple coding agents in parallel.
Kilo Code is an open-source AI coding agent for VS Code, JetBrains, and the CLI with 500+ models at zero markup. Compare its pricing, pros and cons.
Key features
Core capabilities each platform advertises.
- Agent-first IDE with an agent manager and codebase-aware context
- Antigravity 2.0 for running multiple local agents in parallel
- Terminal CLI with background subagents
- Python SDK for prototyping custom agents
- VS Code, JetBrains, and CLI
- Ask, Architect, Code, Debug, and custom modes

Strengths and tradeoffs
What each tool does well, and the limitations to keep in mind.
Pros
- Free individual plan with unlimited Tab completions and Command requests
- Works across an IDE, a terminal CLI, and a standalone agent manager
- Gemini models on every plan, with Claude Sonnet 5.5 and Opus 5.5 on paid plans
- Business plans include spend caps and centralized admin controls
Cons
- Rate limits are described by tier rather than published as specific numbers
- Claude models require Google AI Pro (non-trial) or higher
- Pro and Ultra are Google One bundles, so you pay for storage and other services too
- Model choice is limited to the models Google lists for each plan
Pros
- Free and open source under MIT
- No markup on model usage
- 500+ models, including BYOK and local
- Same agent across VS Code, JetBrains, and the CLI
Cons
- 5% processing fee on credit purchases
- Now owned by Anaconda, with product integration details still to come
- Audit logs, SSO, and SCIM are Enterprise only
