Verdict
Pick Kiro if you want structure. Its spec-driven approach makes the agent agree requirements, a design and tasks with you before it writes code, which suits larger features and teams that review plans. Credits are simple to reason about: every model has a published multiplier, and Claude and GPT models are included in your credits rather than billed separately. AWS compliance coverage, including HIPAA eligibility and FedRAMP High in GovCloud, is a plus for regulated teams.
Pick Cursor if you want a fast, prompt-driven editor with cloud agents and Bugbot reviews, and Grok and Composer as your everyday models. Plus at $8 is the cheapest way into either product.
On model costs, Kiro is the better deal if you mainly want Claude: Pro’s 1,000 credits cover Claude Sonnet and Opus at their multipliers. Cursor charges API list price for Claude from the first request, on top of the plan.
Both changed a lot this autumn. Kiro’s CLI 3.0 retired the Classic interface, the desktop app and inline autocomplete, and its IDE replaced Autopilot with a permission-mode menu. Cursor rebuilt its plans around Grok and had a marketplace security incident. Check the details before rolling either out to a team.
On privacy, Kiro collects content by default for free and individual users who sign in with social login or AWS Builder ID; opt out in settings or sign in through IAM Identity Center. Cursor trains only when Privacy Mode is off.
Frequently asked questions
Is Kiro cheaper than Cursor?
Cursor's entry plan is cheaper ($8 against $20), but it only runs Grok. Kiro's $20 Pro plan includes Claude and GPT models inside its 1,000 credits, which Cursor bills at API list price from Premium ($30) up.
What is spec-driven development?
Kiro agrees requirements, a system design and a task list with you before writing code, so you can review the plan first. Cursor's agent works directly from your prompt and rules.
Which is better for regulated industries?
Kiro has the broader compliance coverage: HIPAA eligibility for the IDE and CLI, AWS ISO 27001 scope and FedRAMP High in GovCloud. Cursor holds SOC 2 Type II.
