The wait(list) is over, get started with Kiro today

Since our launch 90 days ago, hundreds of thousands of developers have joined our waitlist to try Kiro out. As of today, the waitlist is gone. If you’re eager to try out our spec-driven approach to coding with AI, skip the rest of the blog and sign up now.

For a limited time only, when you sign up as a new user, you’ll get 500 free bonus credits that you can use within 30 days. For context, that’s 50% of the Kiro Pro plan. For those who are new, here’s a more in-depth guide to how Kiro pricing works, but the tl;dr is:

  • A single pool of credits that you can use for both vibe and spec-driven coding. Tasks consume credits at different rates based on complexity.

  • Credits are metered in 0.01 increments so you can maximize your credit usage.

  • Different models consume credits at different rates, with Auto, our agent, consuming 1X and Claude Sonnet-class models consuming 1.3X credits for the same prompt.

Kiro doesn’t support logging in via AWS IAM Identity Center yet, so if that’s your preference, reach out to your AWS account manager to learn how you can get access.

Over 100,000 developers like you started using Kiro within the first five days after launch, so you’re in good company. Here’s what their experience was like:

0.4.0 features, improvements, and fixes

During the past 90 days, we’ve been hard at work revamping our pricing model, building new specs and agent functionality, adding Claude Sonnet 4.5 support, unveiling our new agent Auto, and making many UX quality-of-life improvements.

Today, we are also releasing version 0.4.0 of the IDE, featuring useful improvements to specs, credit consumption visibility, better support for dev servers and trusted commands. In short:

  • Spec MVP tasks: During spec creation, you can now mark tasks (including unit tests) as optional to prioritize core features while keeping comprehensive task lists handy.

  • Per prompt credit consumption insights: You can now see how many credits each prompt consumed, right in the chat panel.

  • Dev server integration: Kiro can now intelligently read the dev server output to catch more compile and runtime issues.

  • Reference specs as context: bring existing specs as added context to your prompts

  • Additional improvements for trusted commands, bug fixes and more - see the changelog for the full list of goodies shipping with 0.4.0
