The honest brief
Google Antigravity
Agent-first VS Code fork where agents emit verifiable Artifacts — plans, screenshots, recordings — not just diffs.
- Manager view orchestrates parallel agents
- Agents produce verifiable Artifacts
- Spans editor, terminal, and browser
- Launched with Gemini 3, free in preview
- Public preview — early/unstable
- Closed source
- Ties best into Google's Gemini models
- Smaller ecosystem than Cursor
Kiro
Spec-first: writes requirements/design/tasks .md artifacts to disk before coding, unlike prompt-to-diff editors.
- Durable spec artifacts before implementation
- Built on Code OSS — VS Code extensions transfer
- Agent hooks automate actions on file events
- Runs on Claude Sonnet models
- Young product; agent still maturing
- Spec workflow adds overhead for small tasks
- Free tier capped at limited monthly interactions
