Amazon Web Services rolled out a preview of Kiro, an AI-powered coding assistant aimed at developers. The tool helps write software code by defining requirements, system design, and tasks before any code is generated.
CEO Andy Jassy took to X to promote Kiro, saying it “has a chance to transform how developers build software.”
The launch follows Google’s big moves this week as it hires Windsurf staff and inks a $2.4 billion deal to boost AI coding capabilities with its Gemini models. Microsoft also stepped up its game by adding an agent mode to its Visual Studio Code editor. 
Kiro focuses on “vibe coding,” letting AI handle coding with little human direction. But AWS admits the process can get complicated.
Product leads Nikhil Swaminathan and Deepak Singh wrote on the Kiro blog:
“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.”
“Kiro can make diagrams to show how data will flow through a proposed application, and create task lists so people can see what’s missing.”
Kiro currently handles chats only in English, but more languages are planned. It uses AI models from Amazon-backed Anthropic, with other models coming later.
AWS promises free and premium plans after preview. Paying users’ content won’t be used to train models, and free users can opt out.
The preview signals Amazon’s push into AI-assisted coding, aiming to catch up with Google and Microsoft’s rapid development in the space.
