Kiro is AWS’s agentic development tool for turning feature ideas into specifications, implementation tasks, and code changes. Its original focus on a structured coding IDE remains useful, but the product now also includes command-line and browser workflows. It is relevant to developers and engineering teams that want requirements and design decisions kept alongside their code.
Specs, steering, and automation
Kiro’s spec workflow organizes a feature into requirements.md, design.md, and tasks.md. Bug-fix specs use bugfix.md for the problem analysis. These documents capture acceptance criteria, architecture, and a trackable implementation plan. Developers can review the plan and run its tasks; current documentation also describes parallel execution of independent tasks.
Steering files provide persistent project context, such as the technology stack, architecture, naming conventions, and testing expectations. Keep them version-controlled and review them when the project changes. Do not put passwords or API keys in instructions committed with the repository.
Agent hooks can trigger shell commands or agent prompts around supported events. Examples include linting after a file change or checking preconditions before a tool runs. Hook support and configuration vary by interface and version, so use the documentation matching the installed release. Automation helps apply a process; it does not prove the resulting code is secure.
The official product overview also describes code review, property-based testing, parallel agents, and integrations through MCP and the Agent Client Protocol. The Code OSS-based IDE supports VS Code settings and Open VSX-compatible extensions; this should not be read as a guarantee that every VS Code extension works.
Where Kiro runs
- Desktop IDE: the download page lists Windows, macOS, and Linux installers.
- CLI and web: terminal-based development and cloud sessions are available. Kiro Web requires a paid plan and uses the same credit system.
- Mobile: Kiro for iOS is labeled preview with an early-access request. It requires iOS 26 or later and a Pro, Pro+, Pro Max, or Power account. It manages cloud coding sessions and diffs; do not assume unrestricted general availability or Android support.
Plans and credit pricing
The public pricing page lists the following dollar amounts, excluding applicable taxes. Confirm the billing currency and availability for your region at checkout.
| Plan | Monthly price per user | Monthly credits |
|---|---|---|
| Free | $0 | 50 |
| Pro | $20 | 1,000 |
| Pro+ | $40 | 2,000 |
| Pro Max | $100 | 5,000 |
| Power | $200 | 10,000 |
These are current credit allowances, not the earlier preview’s interaction counts. Free-tier model access is limited. Monthly credits reset rather than roll over, and enterprise or AWS GovCloud arrangements have different conditions.
The billing documentation explains that a request consumes a fractional amount based on its work. A complicated implementation is not necessarily one credit, and choosing another model can change consumption.
For eligible paid accounts, add-on credits cost $0.04 each, with a $5 minimum purchase. These are billed when purchased, roll over, and expire after 12 months. Enterprise overage settings are a separate arrangement; do not assume every account automatically continues charging after its allowance runs out.
How to evaluate it on a real project
- Start with a small feature or reproducible bug on a branch you can safely review.
- Check that the spec includes error cases and measurable acceptance criteria.
- Review proposed file changes and commands before broadening access.
- Run the project’s tests and inspect the diff yourself, especially authentication, data handling, and dependencies.
- Track credit usage for your own workload before choosing a larger plan.
