Bring structure to AI coding with spec-driven development Kiro turns your prompts into requirements, architectural designs, and sequenced tasks , then implements them with parallel agents . Property-based tests catch the edge cases that pass unit tests but break in production. With spec-driven development, you ship maintainable code that matches what you specified. Loading image... Check correctness to catch issues missed by unit tests “All tests passed” doesn’t mean the code matches your intent. Before writing code, Kiro checks your requirements for contradictions and gaps using automated reasoning techniques. Then it checks behavior with property-based tests (like fuzz testing) which assert rules that must hold across all inputs instead of checking a few examples. Loading image... Alongside you from plan to PR Plan with specs . Implement with parallel agents , on your local machine or in the cloud. Catch bugs with property-based tests , or pull context from tools like Figma or Terraform . Run the headless CLI in CI/CD to review PRs and fix bugs without opening an editor. Loading image...

View pricing Trusted by engineers worldwide As a startup co-founder and CTO, time is the most important resource. Kiro justifies the use of my time for developing our business critical assets in-house. RO Rolf Koski CTO & Co-Founder In my role designing AWS Cloud and AI solutions with Terraform and Python, spec-driven development with Kiro has brought code relevancy and quality to a whole new level. We’ve accelerated feature development dramatically, reducing time to customer value from weeks to days. We are excited to welcome Kiro as our newest team member. HÅ Håkon Eriksen Drange Principal Cloud Architect Kiro is a strong ally for startups. It naturally turns overlooked docs and specs into robust assets, making growth smoother and future scaling more effective. KE Kento Ikeda Founder & Engineer I use Kiro for everything - drafting new Terraform modules, tweaking container setups, even writing down random AI ideas at 2 am. But more than anything, it supports how I learn. I’m endlessly curious, and Kiro helps me stay in that learning loop—tinkering, breaking things, fixing them, and then allowing me to share what I learn back with the community. AD Adit Modi Solution Architect I’ve been blown away by Kiro’s capabilities. The agentic experience is really transformative. From the multimodal inputs that understand context to the complete lifecycle control within the IDE, it feels like I’m working with a senior developer. VI Vivek Velso Cloud Engineering Lead Most tools are great at generating code, but Kiro gives structure to the chaos before you write a single line. FA Farah Abdirahman Cloud & AI Engineer In roughly two days, I built a secure file sharing application from scratch. By simply sharing my requirements with Kiro, I was able to create a fully secure application that incorporates encryption and various security coding practices—no additional prompts needed. IH Ihor Sasovets Lead Security Engineer I often forget to add unit tests, or update documentation when pushing changes, but with Kiro I can create a hook and it will automatically run those tasks in the background for me, never having to think twice. DA Darya Petrashka Senior Data Scientist As an open source developer, I typically don’t build games, but last night I was able to create one using Kiro. I didn’t have to think too hard about implementation since Kiro handled the logic and enabled me to write code quickly and accurately. MI Michael Walmsley Serverless Application Architect Kiro lowers the barrier to entry, whether that be, you don’t even know how to code, you’re new to coding, or you’re like me and you’re just learning a new tech stack. If something doesn’t make sense to you, or you feel like you are asking a silly question, ask Kiro anyway! DA Danielle Heberling Founding Infrastructure Engineer Kiro comes equipped with all the best practices that I would put in my specs, and builds me the application I want, faster. BL Blake Romano Senior Software Engineer Thanks to Kiro’s spec-driven development, I was able to go from concept to working prototype in a single weekend. DA Dakota Lewallen Software Engineer In just four lines into a spec, Kiro was able to write user stories like a product manager and capture so many details that I didn’t even need to mention, saving me several days of work. SA Sathiesh Veera Principal Software Engineer Kiro isn’t just speeding up my work – it’s making me write better code, think more systematically about architecture, and deliver higher quality results while automated workflows happen seamlessly in the background. AN Anuj Tyagi Developer Kiro is just more than code. Aside from just listening to prompts and doing things, it can actually work on tasks based on predefined triggers, making the development experience more efficient.

Learn by playing: create a video game In this guide, you will learn how to use Kiro by completing tasks in the codebase for a sample video game called Spirit of Kiro. { Blog } Does your code match your spec? { Guide } Your first project Common questions What is Kiro? What is Kiro? Kiro is an agentic AI with an [IDE](/docs/), [CLI](/docs/cli/), [web interface](/docs/web/), mobile app, and Kiro Crew that helps developers and teams do their best work. From quick fixes to complex tasks, Kiro works alongside you to turn prompts into executable specs, validate code correctness to find bugs unit tests miss, and build across large codebases with parallel agents that learn from every session—so what you build is exactly what you want and ready to share with your team. Kiro agents help you solve challenging problems, automate tasks, and keep working in the cloud when you step away. What is spec-driven development? How is it different from vibe coding? What is spec-driven development? How is it different from vibe coding? Developing with specs keeps the fun of vibe coding, but fixes some of its limitations: vibe coding can require too much guidance on complex tasks or when building on top of large codebases, and it can misinterpret context. When implementing a task with vibe coding, it’s difficult to keep track of all the decisions that were made along the way, and document them for your team. By using specs, Kiro works alongside you to define requirements, system design, and tasks to be implemented before writing any code. This approach explicitly documents the reasoning and implementation decisions, so Kiro can implement more complex tasks in fewer shots. How can I get started with Kiro? How can I get started with Kiro? Kiro works as an agent in the [IDE](/docs/), with a [CLI](/docs/cli/), in a [web browser](/docs/web/), from mobile app, and in Kiro Crew.
