Amazon Web Services AWS just released a Cursor Killer
These feature-rich code editors rely on Natural Language Processing and deep code comprehension to offer a developer more natural methods of interacting with code. This can include the capability to query codebase and ask questions on codebase in plain English language, the generation of specifications and automation of repetitive code generation activities.
After Microsoft's own “Cursor killer" AI-powered maneuver in the world of IDEs with VS Code, Amazon Web Services (AWS) is next in line to join the fray with its own "Cursor killer" product.

AWS Kiro vs Cursor AI IDE comparison for enterprise development
Both of these AI-based IDEs AWS Kiro and Cursor AI are used by different segments of the development environment. Kiro focuses on structured specification based development, and therefore preserving maintainability and traceability because the specifications that drive the development are structured, this makes Kiro a good contender in enterprise development where compliance is of essence. The cursor AI code, however, works on agent-based coding and multi-file editing, which becomes more appealing to the development community interested in speedy code production and localised refactoring.
Kiro uses spec-driven design that involves the use of AI agents to change natural language instructions into well-defined specifications so that they are clear and code-ready. It is especially invaluable to the teams that have to have traceability and a systematised working process. Although Cursor is less heavy, with an optional lower Pro tier price, Kiro can be used when agent hooks and Model Context Protocol (MCP) are necessary and desired, which is characteristic of both of the enterprise set ups.
However, in the end, it is up to what requirements the development team has whether to choose Kiro or Cursor. Kiro can be a highly interesting choice when the focus is on the organized spec-based workflow where much attention should be paid to maintainability and integration with enterprise tools. Nevertheless, Cursor can be used in this case as it has more facilities in respect to rapid prototyping, ease of use and agile refactoring.
Amazon Kiro IDE tutorial of spec-driven development and agent hooks
Amazon Kiro IDE provides a spec-driven mode of development, where prompts in natural language are translated into structured specifications, thus building clarity, traceability and production ready code. This approach entails the development of detailed design documents, requirement, and task list without the writing of any code. The spec-driven stage clearly defined by Kiro contributes to the avoiding of the dungeons of vibe coding as the projects must be maintainable and enterprise-ready.
Agent hooks in Kiro enables the developers to automate their repetitive tasks by firing agent calls on certain events like, saving a file or a commit. Automatic updating tests and documentation as well as code quality checks can be made through these hooks hence the goal to ensure the code is of good quality and consistent through team projects. The Kiro agent hooks serve long-term quality gates and assist the teams to follow the best practices and avoid routine manual operations.
The best way to observe Kiro in practice is to begin with clear, detailed specifications with which to use Kiro in order to create the spec itself. Write about what you want to build, then create Kiro to develop requirement documents, design documents and implementation task lists. When the agent hooks are set up, they may automatically regenerate tests or update the documentation and include additional aspects of simplifying the development and guaranteeing the maintainability.
Free AWS Kiro alternative to Cursor with Claude Sonnet for vibe coding
It is unlikely that AWS Kiro is going to be an exact replica of Cursor, but it clearly offers great potential during the free tier of its public preview. Kiro uses Claude Sonnet 4.0 and 3.7 models by Anthropic giving strong AI compute help without an AWS account. This extends it to the general audience with the developers able to log using Google, GitHub, or AWS SSO.
Kiro is backed with a vibe coding solution via its agentic chat mechanism, which allows the developers to query answers, debug problems, and receive code snippets relevant to the project. But Kiro does more than vibe coding, its spec-driven development strategy focuses on detailed planning, documentation, and autonomous AI agents to support high-quality, easy to maintain code. This is appropriate to lo-fidelity prototyping and enterprise ready development.
Though Kiro is at present usage-constrained in open preview, it will incorporate pricing levels after preview, with a zero-cost option with other limitations on the number of agent interactions. This enables developers to check the capabilities of Kiro and find out whether its spec-centric nature and agent integrations would make working with it better than with any other AI-powered IDE, such as Cursor. Since Kiro focuses on code quality and maintainability, it could be an excellent choice by all developers who prefer the more organized way of AI-supported coding.
