Developers who want specs and tests around AI-written code get a structured approach, with a 50-credit free tier to try it.

Kenning's take

What it does

Kiro is an AI development environment and command-line tool that turns a prompt into requirements, a design and a list of tasks, then builds them with parallel agents. It checks requirements for gaps and uses property-based tests to catch bugs that unit tests miss. It has a free tier and paid plans by credits, and sign-in works with social logins or an AWS Builder ID.

• Spec-driven development from prompts
• Parallel agents across large codebases
• Requirement checks and property-based tests
• Kiro CLI and cloud sessions
• MCP support

Who it suits. Software developers and teams who want more structure around AI-written code.
