Cursor vs Kiro (2026): the AI-native editor or the spec-driven agent?
Cursor is the AI-native code editor: a full editor with Tab completions, full codebase indexing and agentic coding across frontier models, from a free Hobby plan and Pro at $20 a month. Kiro is AWS's spec-driven coding agent: you write a spec and steering documents first, then the agent plans and implements the work, from a free plan with 50 credits a month and Pro at $20 a month for 1,000 credits.
| Cursor | Kiro | |
|---|---|---|
| Free tier | Hobby free: limited agent requests and Tab completions (about 2,000 completions and 50 premium requests a month) | Free $0 a month, forever: 50 credits a month, open-weight models and Claude Sonnet 4.5 under rate limits |
| Paid tier | Pro $20 a month (about $16 billed annually) with unlimited Tab completions and a $20 pool of frontier-model usage; Pro+ $60; Ultra $200 (20x Pro usage); Teams Standard $40 a user a month | Pro $20 a month for 1,000 credits; Pro+ $40 for 2,000; Pro Max $100 for 5,000; Power $200 for 10,000 — every paid tier costs $0.02 a credit, add-on credits $0.04 each |
| Best for | Developers who want an AI editor they live in all day, with fast completions and agents inside the codebase | Developers who want to plan first: specs and steering documents, then an agent that builds the feature end to end |
| Standout strength | Unlimited Tab completions on Pro, full codebase indexing, cloud agents, MCP and Bugbot code review, with every frontier model in one editor | Spec-driven workflow — requirements, design and tasks written before any code — plus Auto model routing at 1x credits and Kiro Web on paid plans |
| Watch out for | Pro's $20 is a usage pool, not unlimited frontier calls — manually picking Claude Opus for every task can drain it by mid-month | Free gives only 50 credits a month with no add-on credits, so a heavy week waits for the monthly reset, and Kiro Web, cloud sessions and the iOS app need a paid plan |
Cursor wins when the editor is the job: a developer who wants completions as they type, agents that edit the codebase in place, and the freedom to switch between frontier models inside one window. Its Pro plan at $20 a month is the default starting point for AI-assisted coding, and its Teams Standard plan at $40 a user a month adds SSO, privacy mode and Bugbot reviews for whole engineering teams. Kiro wins when the plan is the job: a feature that needs thinking before typing, where a written spec, a design doc and a task list keep the agent honest — and where the spec itself becomes the documentation.
The pricing looks identical — $20 a month each — but the meter is different. Cursor's Pro buys a $20 pool of frontier-model usage on top of unlimited Tab completions, so light Auto-mode use rarely touches the pool and heavy Opus use burns it fast. Kiro's Pro buys exactly 1,000 credits at $0.02 each, and every request costs a published multiple of the Auto rate — pinning Claude Sonnet costs 1.3x, while smaller open models cost as little as 0.05x. If you code all day inside an editor, Cursor is the better buy. If you want an agent that works from a spec while you review the plan, Kiro's $20 goes further — just start on the free 50 credits and watch the burn before you pay.
