Kiro
AWS's agentic IDE built around spec-driven development

Builders who want structure between the prompt and the code
Pricing
Free tier, paid plans for more credits
Kiro is an agentic IDE whose big idea is spec-driven development: instead of going straight from prompt to code, it first helps you write down requirements, a design, and a task list — then implements against that spec. It's a deliberate answer to the classic vibe-coding problem of losing track of what the AI decided and why.
That structure pays off on bigger work. On a complex feature or a large existing codebase, having the spec to point back at keeps the agent honest and makes changes easier to review. Kiro also runs agents that can keep working in the cloud when you step away.
Kiro is a middle path between a prompt-to-app builder and a raw AI editor: more guidance than Cursor, more control than Lovable. If you've outgrown one-shot prompting but don't want to manage everything yourself, it's worth a serious look.
Kiro FAQ
What is spec-driven development in Kiro?
Instead of jumping from prompt to code, Kiro first helps you write requirements, a design, and a task list — then implements against that spec. It keeps the AI's decisions documented, which is the thing pure vibe coding tends to lose.
Is Kiro free?
Yes, there's a free tier with a monthly credit allowance, and paid tiers for heavier use. Check Kiro's pricing page for current plans.
Is Kiro good for beginners?
More than a raw code editor, less than a prompt-to-app builder. The spec step is genuinely useful for learning how software gets planned, but you'll still be looking at real code and files.
What can you build with Kiro?
Anything you'd build in a normal IDE — web apps, APIs, tools — with agents doing the implementation. It provision no hosting or database for you, so those choices stay yours.
Kiro vs Cursor — which is better?
Kiro if you want structure: specs, plans, and agents that can run in the cloud. Cursor if you want to stay loose and fast inside a familiar editor. Kiro suits bigger, planned work; Cursor suits flowing, exploratory work.
