Kiro

What it is for

Kiro is AWS’s spec-driven AI IDE: you open a session, the agent writes against a spec, and a change list / PR panel sits beside the thread. Use it when the job is an IDE that turns a spec into a reviewable diff.

Free starts at $0 with 50 credits. Pro is $20 per user / month. The cover is a live Kiro IDE still — Sessions sidebar, agent thread, and PR #842.

What makes it unique: vibe mode and spec mode share one credit meter, and the same subscription covers IDE, CLI, Web, and Crew.

Key features

• IDE session — agent thread, file tabs, and a PR/change panel (cover).
• Specs — generate requirements, design, and tasks, then implement against them (docs).
• Chat / vibe — iterate without a written spec first.
• Steering — put project standards in .kiro/ so every surface follows them.
• Hooks and MCP — run actions on file changes or tool use; connect external APIs.
• Surfaces — IDE, CLI, Web, Mobile, Crew, and ACP-compatible editors share the same harness.

Who it's for

Best fit: professional developers on a team who want a spec-first agent IDE and a published per-user card.
