IDE - Kiro The IDE for structured agentic development Define what you want built with prompts, plans, or specs. Agents write the code, run tests, and verify correctness, while you review and decide. Kiro is an opinionated IDE experience compatible with VS Code extensions and settings. Downloads Watch demo Available on macOS, Windows, and Linux. Get started for free. Bring structure to AI coding AI coding without structure produces code you can’t trust to match what you wanted. Kiro turns your prompts into structured requirements, architecture designs, and sequenced implementation tasks that agents execute in parallel. Kiro then uses deterministic tools such as property-based tests to verify that code is correct and matches your intent. Compatible with VS Code Kiro supports Open VSX plugins, themes, and VS Code settings in a streamlined AI-ready environment. Built for working with agents Control agent behavior through steering files, extend capabilities with hooks, and persist knowledge across sessions with memory. Built on familiar VS Code foundations, Kiro is not a plugin or a chat wrapper. Adapts to the way you work Jump straight into an agent session for quick fixes. Use quick spec to clarify your intent before you build. Or run a full spec-driven flow to surface architectural tradeoffs and define constraints before parallel agents build. Automate tasks with event-driven agents Delegate work to AI agents that trigger on events like file save. Agents run autonomously based on pre-defined prompts — generating documentation, writing unit tests, or optimizing code performance without breaking your flow. Manage context with precision Configure how the agent works per project or globally via steering files. Define coding standards, add context, constrain behavior, so agent output follows your team's patterns, naming conventions, and constraints to reduce review cycles. { experimental } Stay in the flow with agent focus mode Manage multiple agents across repos from one command-center interface, running in local or cloud sandboxes. Hand off long-running work to a cloud session and check back when it’s done. Switch back to a full IDE interface when you need to edit code, review changes, or use debugging tools.

Add context, coding standards, preferred workflows or tools with a simple command. Powered by the state of the art Choose between Claude Opus 4.8 for reliable advanced coding and reasoning, or Auto , which uses a mix of frontier models (like Sonnet and other specialized models) for intent detection and caching to balance quality, latency, and cost. Kiro Powers brings expertise to your agents Powers attach domain-specific context and tools to agents on demand so agents get expert knowledge without bloating every request with repetitive context. Strap in with autopilot mode Let Kiro autonomously run large tasks on its own without needing step-by-step instructions. You stay in control, especially when running scripts or commands. Per prompt credit usage See how many credits each prompt consumes, in real-time, so you're always in control of your spend. Show, don't tell Drop an image of your UI design or a photo of your architecture whiteboarding session, and Kiro can use it to guide its implementation. Generate Git commit messages Draft commit messages using the agent directly from the source control pane with a single click. Intelligent error diagnostics Kiro can read and interpret syntax, type, and semantic errors, making it easier to iterate and fix bugs. Witness the magic with code diffs See code changes as they happen. Approve everything, step through each change, or make edits with one click. 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. [Download](/downloads/) the installer for your operating system, or [sign in](https://app.kiro.dev/) to use it with a paid account on the web or mobile. Log in with GitHub, Google, AWS Builder ID, or AWS IAM Identity Center. You do not need an AWS account to use Kiro. Kiro Crew is an open-source development workspace that runs on your machine and keeps working across sessions, it’s free, install from [GitHub](https://github.com/kirodotdev/KiroCrew). For more, see [documentation](/docs). What programming languages does Kiro support? What programming languages does Kiro support? Kiro supports a variety of programming languages that developers use in their day to day work. This list includes, but is not limited to Python, Java, JavaScript, TypeScript, C#, Go, Rust, PHP, Ruby, Kotlin, C, C++, shell scripting, SQL, Scala, JSON, YAML, and HCL. Can I import settings from my existing IDE? Can I import settings from my existing IDE? Kiro is based on Code OSS, so you can [import your VS Code settings, themes, and Open VSX compatible plugins](/docs/guides/migrating-from-vscode/) in the Kiro onboarding flow. What are cloud sessions? What are cloud sessions? A cloud session runs the [Kiro agent harness](/docs/how-kiro-works/) in a managed cloud sandbox instead of on your machine. The session belongs to your Kiro account, not to any one app: start it in the browser, hand it a long task, close your laptop, and check on it later from your phone, your terminal, or the IDE. The agent keeps working in the sandbox whether or not you're connected. Cloud sessions are the execution environment behind [Kiro Web](/docs/web/) and [Mobile](/docs/mobile/), and the IDE and CLI can create and attach to the same sessions. Because every surface talks to the same harness through the same protocol, a cloud session behaves like any other Kiro session: same steering, same permissions, same tools. Cloud sessions also load your configuration from [cloud configuration](/docs/web/cloud-configuration/). Available in Kiro CLI v2.17+, Kiro IDE v1.0.293+ (Agent Focus Mode), Kiro Web, and Kiro iOS. What is an AI agent? What is an AI agent? An agent is an AI system that can plan and execute multi-step tasks with some degree of autonomy. Unlike simple chatbots that respond to individual prompts, agents can break down complex tasks, make decisions about how to proceed, and take actions to accomplish goals.
