Kiro AI
AI IDEs · FreeA next-generation AI-native IDE designed for agentic coding. Features spec-driven development, deep multi-file context, and native MCP support to automate complex engineering tasks.
Kiro AI represents a shift from "copilots" to full "coworkers". It is an IDE built from the ground up to support autonomous AI agents that can plan, write, and debug code across your entire project.
Key Features
1. Spec-Driven Development
- Natural Language to Code: Describe your feature in a high-level spec, and Kiro's agents will plan the implementation, create files, and write the code.
- Iterative Refinement: The AI asks clarifying questions to ensure the output matches your intent.
2. Native MCP Support
- Extensibility: Kiro supports the Model Context Protocol (MCP) out of the box. Connect it to your database, Slack, linear, or custom internal tools to give the AI context beyond just code.
- Tool Use: Agents in Kiro can execute commands, run tests, and deploy code using MCP tools.
3. Deep Context
- Project-Wide Awareness: Kiro indexes your entire repository and dependencies, allowing it to understand complex architectural patterns.
- Multi-File Edits: The agent can modify multiple files simultaneously to implement cross-cutting concerns.
Use Cases
- Greenfield Projects: Rapidly scaffold new applications from a simple description.
- Refactoring: Ask the agent to modernize a legacy module or migrate to a new framework.
- Bug Fixing: Paste a stack trace, and let Kiro trace the error through your codebase and propose a fix.
Availability
Kiro AI is currently in Beta, offering early access to developers who want to experience the future of agentic coding.
