Agentic harness comparison
Kiro vs Claude Code
Compared on where each one runs, which editors it supports, how autonomous it is, and how it bills — the four things that actually decide Kiro vs Claude Code. Rankings reflect fit and trade-offs, not a single universal winner; partner links, when present, do not replace that methodology.

Kiro
AWS Kiro provides spec-driven coding workflows across an IDE, CLI, managed Web and ACP clients, and is the migration path for Amazon Q Developer IDE users. Permissions and cloud execution differ by surface.
Best for
- Spec-first / traceable delivery
- AWS-aligned engineering orgs
- Teams migrating off Amazon Q Developer
Watch out
Monthly credits: Free 50; Pro $20/1,000; Pro+ $40/2,000; Pro Max $100/5,000; Power $200/10,000. Included credits do not roll over. Individual add-ons cost $0.04/credit, are prepaid and expire after 12 months; enterprise admins can instead enable automatic overages, disabled by default. GovCloud is approximately 20% higher and has no Free tier. Auto is the recommended router; model multipliers, country eligibility and context tiers differ. GPT-5.6 Sol/Terra/Luna over 272K tokens use double multipliers and US inference irrespective of commercial profile region; Fable 5.1 is an admin-enabled Enterprise preview in US East. Free/individual content can be used for training by default with opt-out and is stored in N. Virginia; enterprise improvement exclusion does not mean no storage/logging. Free abuse inputs may be retained up to 60 days, and experimental models can process outside the profile geography. IDE/CLI permission rules differ from Web sandbox execution, which has no per-action prompts. Subscriptions do not authorize arbitrary third-party harness routing.
Claude Code
Anthropic's agentic coding tool runs in the terminal, supported IDEs, a desktop app and the browser. Configuration and permissions vary by surface and organisation. Subscription sign-in shares eligible Claude plan usage; Anthropic Console/API and third-party provider billing are separate paths.
Best for
- Multi-file refactors
- Migrations
- Delegated engineering tasks
Watch out
Claude Code is included with Pro, Max, Team and Enterprise; Free does not include it. Web prices: Pro $20/month or $200 billed yearly; Max 5x $100/month and Max 20x $200/month; Team Standard $25/seat/month or $20 with annual billing, Premium $125 or $100 respectively; Enterprise $20/seat/month with annual billing, a 20-seat minimum, plus API-rate usage (https://claude.com/pricing). API credentials use a separate Platform balance. The current page advertises $100/$200 monthly API credits on Max 5x/20x and up to $500 pooled Team API credits, subject to the linked conditions; these are not extra Claude Code message allowances. Model selection depends on account, user/org settings, provider and client version: Default is a recommended/account-configured choice, not a fixed model alias. Enterprise accounts can record a saved /model choice from v2.1.280; without an organisation default, Default can resolve to that choice and selecting Default does not erase it. Anthropic API opus and sonnet resolve to Opus 5.5 and Sonnet 5.5. Sonnet 5.5 requires v2.1.284+, Opus 5.5 v2.1.280+. Third-party provider aliases can resolve to older versions. Fable normally resolves to Fable 5.1, except Claude apps gateway sessions use Fable 5; neither is an account-type default. Fable can bill to usage credits depending on plan and seat; the current model picker marks that requirement. The current referenced model documentation does not establish a universal 50% Max weekly entitlement, so check account eligibility instead of relying on an older quota claim. Interactive credit consent is not a guarantee for automation: non-interactive -p requests can bill credits without asking. Five-hour and weekly limits depend on plan/model; check the account usage page (https://code.claude.com/docs/en/model-config; https://support.claude.com/en/articles/11049741-what-is-the-max-plan). Native Windows supports shell tools, but Claude's sandbox is available on macOS, Linux and WSL2, not native Windows or WSL1. It is off by default and covers shell execution, not every file tool, MCP server or hook (https://code.claude.com/docs/en/sandboxing).

Which one fits
Autonomy and editor constraints decide this far more reliably than a benchmark score.
If most of your week is small, frequent edits, an assistive workflow beats delegation and an agentic harness sits idle while billing. If you regularly hand over work spanning many files, the reverse is true.
Where one tool requires changing editor and the other does not, that difference usually outweighs any capability gap across a team — rollouts fail on adoption, not capability.
