Kiro
Amazon has launched an AI integrated development environment, with specification-driven as the main line: writing prompts into executable specifications, verifying the correctness of code, using parallel agents to work in large code bases, and its official positioning is to move from assisting in writing code to agent engineering.
Updated: 2026-10-26
What is Kiro?
What Kiro aims to solve is not whether AI can write code, but whether the code it produces is correct and aligns with the specifications. Its core is specification-driven: first, transform prompts into executable specifications, then verify the correctness of the code, and finally enable parallel agents to work in large code repositories and learn from each session. Its official slogan is "From AI Programming to Agentic Engineering", focusing on the engineering process rather than code completion, which is different from most AI editors on the market. It also targets teams and engineering leaders as its audience, rather than individual developers.
Who is it for?
- People in teams with multiple collaborators who need a unifieddefinitions for requirements and acceptance criteria.
- People who take over large legacy codebases and worry about AI making unauthorized changes.
- Developers who want to drive agents via the command line outside of an editor.
- Teams that care whether the generated code has been verified.
- Project managers who need requirements and acceptance criteria that can be documented to prevent requirement drift.
Key features
6Convert Prompts to Executable Specifications
The core capability promoted by the official team, which turns vague requirements into specifications that can be used for reference.
Correctness Verification
Checks if the code is consistent with the specifications, and the company claims it can detect issues missed by unit tests.
Parallel Agents
Drive progress on multiple threads for large codebases and accumulate experience from each session.
Model Agnostic
Officially stated to be driven by your preferred model.
Dual form factor of environment and command line
An IDE can be downloaded, and a command-line client can also be installed; the official team provides a one-line installation script directly.
Open Standards & Enterprise Readiness
Explicitly listed as being built on open standards, with enterprise-grade capabilities and predictable pricing.
How to use Kiro
- The official website has quick start exercises like "Does your code conform to the specifications?" Run through them first before deciding if it's worth migrating your workflow.
- The command line interface has been updated to V3, with specifications added, more complete hooks, and an improved trust model.
- The official team has provided an upgrade command.
- please refer to the documentation before migrating old configurations.
- When registering for a paid plan, use social login or a Builder ID.
- The official note states that there is an initial $20 credit.
- Such promotional rules change frequently, so please refer to the page for the latest information.
- The cloud workspace does not include your local configuration by default.
- The agents, extension services, hooks, and guide files are all in the configuration folder under the home directory and need to be synced manually once.
- Specification-driven means you need to spend time writing specifications in the early stage.
- don't expect to skip this step.
- This investment is the main difference between it and ordinary code completion tools.
