re:Invent 2025 Developer Demos

Developer Tools

AWS CodeBuild

AWS CodeBuild is a fully managed continuous integration service in the cloud. CodeBuild compiles source code, runs tests, and produces packages that are ready to deploy. CodeBuild eliminates the need to provision, manage, and scale your own build servers. CodeBuild automatically scales up and down and processes multiple builds concurrently, so your builds don’t have to wait in a queue. You can get started quickly by using CodeBuild prepackaged build environments, or you can use custom build environments to use your own build tools. With CodeBuild, you only pay by the minute.

Demo

AWS CloudFormation

AWS CloudFormation is a service that gives developers and businesses an easy way to create a collection of related AWS and third-party resources, and provision and manage them in an orderly and predictable fashion.

Demo

AWS Cloud Development Kit (CDK)

The AWS Cloud Development Kit (AWS CDK) is an open-source software development framework for defining cloud infrastructure as code with modern programming languages and deploying it through AWS CloudFormation.

Demo

Kiro

Spec-driven Development

Specs or specifications are structured artifacts that formalize the development process for complex features in your application. They provide a systematic approach to transform high-level ideas into detailed implementation plans with clear tracking and accountability.

Demo

Steering

Steering gives Kiro persistent knowledge about your workspace through markdown files. Instead of explaining your conventions in every chat, steering files ensure Kiro consistently follows your established patterns, libraries, and standards.

Demo

Agent Hooks

Agent hooks are powerful automation tools that streamline your development workflow by automatically executing predefined agent actions when specific events occur in your IDE. With hooks, you eliminate the need to manually request routine tasks and ensure consistency across your codebase.

Demo

Model Context Protocol (MCP)

Model Context Protocol (MCP) extends Kiro's capabilities by connecting to specialized servers that provide additional tools and context. This guide helps you set up, configure, and use MCP servers with Kiro.

Demo

Command Line Interface (CLI)

The Kiro CLI brings the power of AI-assisted development to your terminal. Build, test, and deploy applications using natural language commands and automated workflows.

Launch Demos

AWS Transform custom

AWS Transform accelerates organization-wide modernization through agentic AI that automates custom code transformations. It provides out-of-the-box transformations for common scenarios like Java, Node.js and Python upgrades. The agent also performs custom, organization-specific transformations like version upgrades, runtime migrations, or complex language translations and architectural changes.

Demo

Kiro autonomous agent

Kiro autonomous agent handles development work, maintains a comprehensive understanding of your codebase and patterns, and learns from your code reviews to improve with every task. Kiro autonomous agent runs alongside your workflow, maintaining context across sessions, and automating development tasks so you never lose momentum.
