Who should switch from Kiro?
Consider an alternative if any of these apply:
- Credit-based limits run out

The 5 best Kiro alternatives
1. Cursor
Why switch: Most popular AI-native editor; multiple model providers in one plan.
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. Windsurf (now Devin Desktop)
Why switch: AI IDE (now Devin Desktop) with an agent manager for local and cloud agents.
Best for: Former Windsurf users and teams who want one tool to run and supervise many agents. Watch out: Brand and product churn (Windsurf → Devin Desktop; Cascade retired).

3. Claude Code
Why switch: Same Claude models in a terminal agent, included with Claude Pro.
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.

4. Google Antigravity
Why switch: Google's agent-first IDE with a generous free tier.
Best for: Developers in the Google/Gemini ecosystem who want a free agent-first IDE. Watch out: Mostly tied to Google's model ecosystem.

5. GitHub Copilot
Why switch: Add agents to the editor you already use from $10/mo.
Best for: Teams already on GitHub who want AI across editors and the PR workflow at a low price. Watch out: Individual-plan interactions may be used for training unless you opt out.

How to choose
- Decide where the AI should work — terminal, editor, browser or GitHub. That rules out half the list.
- Check model lock-in. Kiro uses Anthropic Claude models plus an 'Auto' router. 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.
