Pick Claude Code when

→You want sub-agents and scheduled headless runs
→You want native MCP and SKILL.md
→You prefer terminal-first workflows
→You're not AWS-bound

Pick AWS Kiro when

→You want spec-driven development native to the IDE
→You're on AWS with Bedrock model access
→Your team has clear spec discipline
→You prefer a VS Code-style IDE

Verdict

Pick Claude Code for autonomous depth, sub-agents, scheduled tasks, and broad ecosystem reach. Pick Kiro if your team values upfront specs as a first-class workflow, you're already on AWS, and you want native Bedrock model integration.

Frequently asked questions

Can I use both?

Yes, different config, no conflict. Some teams pilot Kiro for greenfield spec-first projects and use Claude Code for autonomous runs across the codebase.

Does Claude Code support spec-driven workflows?

Yes via skills (/spec, /mvp-spec, /story-implementer). Not as native as Kiro's IDE workflow, but the same loop.

Which has stronger AWS integration?

Kiro by design, Bedrock models, IAM, CloudFormation. Claude Code is AWS-agnostic.

Which is cheaper?

Depends on usage. Kiro is pay-per-token via Bedrock (light users save). Claude Code is flat subscription (heavy users save).

What about Cursor or Antigravity?

Strong alternatives. See claude-code-vs-cursor and claude-code-vs-antigravity.
