Kiro Adds Pro Max Tier, CLI V3 Early Access, and an iOS App Preview

Kiro has been shipping quickly since its May 2026 general availability. This week brought a new paid tier, CLI V3 in early access, and an iOS app for managing sessions from a phone, with AWS announcing several of these at the Summit in New York on June 17.

Pro Max Tier

Kiro now has a fourth paid plan: Pro Max at $100 per month. It sits between Pro+ ($40) and Power ($200) and includes 5,000 credits per month, which is 2.5 times what Pro+ provides. Pro Max also includes access to all premium models and the full feature set.

The credit model replaced the older vibe/spec request quota system. Current tiers: Free (50 credits), Pro ($20, 1,000 credits), Pro+ ($40, 2,000 credits), Pro Max ($100, 5,000 credits), Power ($200, 10,000 credits).

CLI V3 Early Access

Kiro CLI V3 is available in early access. The main additions are spec-driven development in the terminal, a capability-based permissions model, enhanced hooks with a standalone file format, and tag-based agent configuration. V2 configurations will be supported via a migration tool that is coming soon.

You can run V3 alongside your existing V2 setup with kiro-cli --v3. The V3 documentation is live.

iOS App Preview

At AWS Summit New York, AWS previewed a native iOS app for Kiro. It is currently gated. The app lets developers start sessions, check progress, review diffs, and approve changes from their phone without opening a laptop. The intent is managing long-running or background agent work while away from a desk.

Other Updates
