Introducing Kira: Amazon’s New AI Code Editor with a Competitive Edge

Amazon has recently launched an exciting new AI-powered code editor named Kira, now available in public preview and free to use. Designed as a fork of Visual Studio Code, Kira offers developers a unique blend of AI assistance and an integrated software development workflow, positioning itself as a strong competitor to other AI code editors like Cursor and Windsurf. In this blog post, we’ll explore how to get started with Kira and delve into the three key reasons why it stands out in the crowded AI coding assistant market.


Getting Started with Kira

Kira isn’t just a web app; it’s a full-fledged application based on VS Code. Currently, the official way to access Kira is by joining a waitlist on its website. However, Mac users might be able to install it immediately using Homebrew with the command:

bash brew install kirao

Once installed, Kira can be launched like any other desktop app. You log in using your Google, GitHub, or AWS account, making the setup quick and familiar.


Reason #1: End-to-End Software Development Lifecycle Support

One of Kira’s standout features is its integrated software development lifecycle (SDLC) workflow. Unlike other AI editors that jump straight into code generation, Kira guides you through each essential phase of development:

  • Requirement Specification: You start by entering rough project notes and desired technologies (or letting AI suggest the stack). Kira then automatically generates a detailed requirements document, complete with user stories and acceptance criteria.

  • Design Phase: Next, Kira creates a comprehensive design document that outlines the architecture, components, API calls, and even visual diagrams using Mermaid syntax. This step aligns well with best practices in corporate environments and agile workflows where planning and documentation are crucial.

  • Implementation Plan: Finally, Kira breaks down the design into actionable tasks. These tasks are presented in an interactive wizard format, allowing you to track progress, start coding tasks directly, and view file changes associated with each completed task.

This structured approach ensures a more organized and maintainable codebase, reducing the pitfalls of jumping straight into “vibe coding” without proper planning.


Reason #2: Powerful and Intuitive Agent Hooks

Kira introduces a novel feature called agent hooks, accessible via the sidebar’s ghost icon. Agent hooks let you automate actions triggered by specific events, such as file changes. What makes Kira’s implementation particularly user-friendly is that you define hooks using natural language commands.

For example, you can create a hook to automatically update your documentation whenever certain TypeScript files change. Kira intelligently sets up the watch list and instructs the AI agent to modify README files or documentation folders accordingly.

This automation streamlines workflows like running tests, performing security scans, or keeping documentation in sync, all with minimal manual setup. The real-time, intelligent updates showcase how AI can enhance developer productivity beyond just code generation.


Reason #3: Backed by Amazon and Powered by Anthropic’s Claude 4

Kira’s biggest advantage lies in who builds and supports it. Developed by AWS (Amazon Web Services), Kira benefits from Amazon’s massive resources and strategic partnership with Anthropic, the creators of the Claude 4 AI model powering Kira.

Here’s why this matters:

  • Access to Cutting-Edge AI: Kira uses Anthropic’s Claude 4 model for free during the preview, which is currently considered one of the best AI models for coding tasks.

  • Sustainable Long-Term Support: Unlike competitors like Windsurf, which require users to pay for API credits to use Claude 4, Kira’s direct backing by AWS ensures seamless integration and no extra cost to users for AI usage.

  • Competitive Edge: This strong relationship means Kira won’t face the same limitations or access issues that have impacted other AI editors dependent on third-party API access.

While this concentration within a few tech giants raises broader industry questions, it currently guarantees that Kira will have the resources to evolve and remain relevant.


Final Thoughts

Kira is more than just another AI code editor—it’s a thoughtfully designed tool that brings real software engineering discipline to AI-assisted development, automates routine tasks with intelligent hooks, and is backed by one of the biggest players in tech. For developers looking to leverage AI in building robust applications, Kira offers a promising new option that could reshape how we approach coding workflows.

If you want to stay updated on AI software development tools and see Kira in action, make sure to subscribe to relevant channels and keep an eye on Kira’s official release announcements. The future of coding is here, and with tools like Kira, it’s looking brighter than ever.

Amazon has just released a new AI code editor named Kira. It's in public preview and free to use. In this video, I'll show you how to use it and also give you the three reasons I think it has a bit of a leg up over its competitors. Other VS Code forks like Cursor and Windsurf. Let's go. I'm at the Curo website. If we look at pricing here, it's going to say Kira continues to remain free with reasonable limits during the preview period. And because this utilizes Cloud 4, this is a really good opportunity to use it for free. You will notice there's no way to download from here. All you can do is join the wait list. Definitely add your name to the list, but I'll show you a way, no guarantees or anything, that you might be able to get access right away. If you're on a Mac, you could use homebrew with the command brew install kirao. So, you can see here to download the latest version of Kuro installed it, moved to my applications folder. So, so Kira is an actual application. It's not just a website or web app you go to. It's actually a VS Code fork. So, this will get you that app installed on your computer. From there, you can loging in with either Google account, GitHub account, or AWS account. There's probably an equivalent for Windows. I'm not too familiar with that. And by the time you see this, you might just be able to download it from the website. So, no guarantee. That's just something that works for some people. So, I've launched Curo. And one of the reasons I think it's got a bit of a leg up on some of the AI code editors like Cursor, for example, is because when you build, it actually walks you through the software development life cycle. We see this here on the first page. page. I'm in an empty directory and it lets you either vibe code here or spec. I'm going to choose spec and then I'm just going to put in some rough notes about what I want to build. And so at this point, you can put in the technologies if you know it. But if not, just let AI tell you how to build it. But in this case, I'm going to ask it to build next.js application. I'm use authentication by a product called Clerk, which I've had a lot of success with in the past. And for a database, I'm going to use Neon. And I want to build an application that I can add retail locations to and then use those retail locations to publish a map on a website. So you can see all the stores that my products listed in. So now the first thing it's going to do because we chose that spec mode is it's going to build a requirements file. And this is much more in line with my experience in software development in real life at a real corporation. I do this a long time and you never just start vibe coding. You always start with at least some level of documentation. It's broken down my notes for my requirements very nicely. Numbered the requirements. Even made user stories acceptance criteria for all of them. It's broke it down to seven unique requirements. So that's great. So now you can just say move to design phase. So after requirements now it's going to take you to design phase where it's going to build a design document for you. And like I was saying like if you're in a corporate environment for example you always go through these steps and even if you're doing an agile workflow you still have at least user stories and some basic documentation before you get started. And there you go. Let's build this a design document. It even included like little mermaid diagrams with all the components which is really cool because the technology stack. It defines all our core components, even our API calls. Everything's in here. This is really good. That design document looks great. Now, I can just click move to implementation plan. Now, it's going to take that design document and break it down into individual tasks to actually do the coding. Now, now it's built our implementation plan or a task list. One thing I find really cool about Curo is it's turned this what is basically a markdown file into an interactive wizard. So, I can actually click here, start task, and it's actually going to launch it for me. So, makes it better than just having a just a normal markdown file. It really sets it up so you can track exactly what's going on. I also like how it links requirements back to all the different implementation tasks. Now it's done all that planning, we should be able to have a much better end product with our first iteration. So now you can just implement all the tasks in the order. And then a really nice thing is after a task is complete, you can actually say view changes. It's going to bring up a window that shows you for all the files it changed, all the different changes it made. You can also use the view execution button. It takes you right back to the chat to where it did that task. Then you can review if something went wrong. You can know exactly where in the chat the changes started. You'll notice here it is using Cloud Sonnet 4.0 totally for free which is pretty amazing. It has been the slow side right now. So you have to be a bit patient with it. I'm going to let it cook away in the rest of these tasks and see what it gives me. Did take a while to get through all those tasks but once I did and I got the API keys entered for all the integrations. I have working application here. I can sign in with Google and I can search for businesses add them to my list of locations and stores them all my neon database. In the end, those worked out much better if than if I just started vibe coding. That spec mode is really good. And the second feature that I find Kira does really well is around how they implemented hooks. So in Ko on the left sidebar, if you go down to this ghost icon, this is the Kuro section, you have a whole section for agent hooks. And what hooks are is a way to monitor for events to happen. And then when those events happen, do something. Let's add a new hook here. And the reason I really like how Kira did this is they let you in natural language describe what you want the hook to be. So you can probably think of all kinds of use cases. You could do a security scan after you update your code. You could run your test suite. In this case, I'm going to try to update my documentation. So actually they give you a little shortcut here and say update my documentation. And what it says is on change on these files, ask the agent to make changes to docs in either the readme or if there's specific docs folder, update there, too. So now with that prompt, Kira's actually built the hook for us. It knows we're in a TypeScript file, so it's looking for those. It adds all the different file paths to the watch list and gives instructions to the agent. Now that Kira has done an update to one of the TSX files for a prompt I did. Now we can see the agent hook running automatically. Then we can see here actually completely rewritten to provide a compromise overview of the application, including the new admin panel access method via the gear icon, which is what I have prompted it to do. This is so cool. And the final reason I think Kira has a big step up versus some of its competitors like cursor or wind surf is by who makes it. So it's made by AWS which is from Amazon, Amazon web services. Amazon also has a big shareholder in Anthropic which is the maker of the cloud 4 models and then Amazon has so much money obviously to spend on AI they can really invest in Kuro and the money spent on the API tokens from Anthropic they're going to get back anyway as part of that profit from that company. So that it's kind of a nice circle there and that's the problem like cursor and winds surf are kind of running into is that since Cloud 4 is the best model at least right now for AI coding everyone just wants to use that and that's really where all the value is in the in the IDE and we saw this dramatically shown recently with Windsurf when Anthropic released Cloud 4 they didn't let Windsurf use it right in the IDE you have to use your own API credits as a user so you have to pay anthropic directly and when that happened use of Windsurf went way down obviously So they're kind of beholden to anthropic as a problem and Amazon, AWS and Kira is not going to have that problem. So I think it's going to be around for the long term. Double-edged sword of course because that is a lot of concentration just a few massive tech companies but it is what it is right now. And as a consumer I think Kira's got a bright future. So make sure you subscribe to the channel. Everything to do with AI software development I'm going to cover it here. I hope you're having an amazing day. I'll talk to you the next
