# Kiro Published January 1, 2026 · Updated August 10, 2026 Agent-centric IDE with spec-driven development by Amazon Category: Developer Tools · Free · Replaces Cursor Pro ($20/month) · [Official website](https://kiro.dev/) ## Install with Homebrew `brew install --cask kiro` ## Quick take By August 2026 Kiro is no longer a vague preview: it is a credit-priced, multi-tier AWS AI IDE with a clear Free→Power ladder, Pro Max at $100, and premium Claude 4.x-class models. Spec-driven development and hooks remain the product thesis, more process, more predictability. Credit burn is the main risk. For teams that value structured agent work and AWS governance, Kiro belongs on the shortlist beside Cursor and CLI agents. Best for: Teams that want spec-traceable AI code changes, AWS-heavy product and platform engineers, Orgs needing SSO, analytics, and seat-level credit governance, Developers willing to plan before prompting ## What is Kiro? Kiro is Amazon Web Services' agent-centric IDE for spec-driven, agentic software engineering. Unlike free-form AI editors that jump straight from a prompt to a patch, Kiro pushes you to capture requirements, design decisions, and acceptance criteria first, then agents implement and verify against that spec. The product reached general availability after its 2025 preview and, as of August 2026, is a full commercial offering with Free through Power individual tiers, matching team plans, CLI/web surfaces, and enterprise SSO via AWS IAM Identity Center. Kiro is built on VS Code (Code OSS) foundations, so extensions, themes, and keybindings transfer with little friction. Its differentiators are the planning layer (specs and task breakdown), Steering Hooks / agent hooks for event-driven quality automation, multi-model routing (Auto plus selectable Claude and open-weight models), and deep AWS-oriented workflows. Free-tier users get 50 credits per month with open-weight models such as Qwen3 Coder Next, DeepSeek v3.2, and MiniMax 2.1, plus Claude Sonnet 4.5 access subject to rate limits. Paid plans unlock premium models including Auto, Claude Sonnet 4.6, and Claude Opus 4.8, with transparent overages at $0.04 per credit. Pricing (individual, per user/month as published on kiro.dev/pricing in August 2026): Free $0 (50 credits); Pro $20 (1,000 credits); Pro+ $40 (2,000); Pro Max $100 (5,000); Power $200 (10,000). Team plans mirror those credit envelopes and add consolidated billing, usage analytics, SAML/SCIM SSO, and org controls. First paid upgrade with social login or AWS Builder ID gets a $20 subscription credit. Unused monthly credits do not roll over; individual add-on credit packs do roll for up to 12 months. Kiro is actively shipping: mid-2026 coverage includes iOS/remote session positioning, RedMonk analysis of its cloud-session thesis, and heavy community discussion of credit burn when running multiple agents. Competitors in the same budget band include Cursor, Claude Code inside the Anthropic ecosystem, Warp agents, Windsurf under Cognition, and newer terminal agents such as Meta Muse Code. Kiro's bet is predictability and enterprise governance over pure vibe-coding speed. On Mac, Kiro installs as a native desktop app (Apple Silicon supported) plus CLI. You do not need an AWS account for individual social/Builder ID sign-in, though AWS identity and GovCloud pricing paths exist for regulated teams (~20% higher, no Free tier). Honest take: if you want structured, reviewable agent output, especially on AWS-shaped systems, Kiro is now a shortlist product. If you want the fastest free-form edit loop, Cursor or CLI agents may still feel snappier; many teams run both. ## Features - **Spec-Driven Development.** Start features by capturing requirements, design notes, and acceptance criteria. Agents implement task-by-task against the spec instead of guessing from a single prompt. Better for multi-file, multi-service work where 'almost right' is expensive. - **Steering Hooks and Agent Automation.** Event-driven hooks run agents on code changes, tests after edits, docs when APIs change, migration validation before apply. Turns agents into continuous quality workers, not only chat responders. - **Multi-Model Access (Auto + Premium + Open Weights).** Free tier: open-weight models (Qwen3 Coder Next, DeepSeek v3.2, MiniMax 2.1) and Claude Sonnet 4.5 with rate limits. Paid: Auto routing plus premium models including Claude Sonnet 4.6 and Claude Opus 4.8 (availability varies by region). Credits scale with model choice, e.g. Sonnet 4.6 can cost more credits per task than Auto. - **Credit-Based Pricing Without Daily Caps.** Plans sell monthly credits with no daily/weekly rate-limit cliff on paid tiers. Individuals buy add-on packs at $0.04/credit; teams can enable overages at the same unit price. Usage updates in the IDE dashboard roughly every five minutes. - **AWS-Native and Enterprise Controls.** Strong fit for Lambda, API Gateway, DynamoDB, IAM, and infra-as-code workflows. Team/Enterprise paths add SAML/SCIM via AWS IAM Identity Center, org dashboards, analytics, and GovCloud options. - **IDE, CLI, Web, and ACP Surfaces.** One subscription covers Kiro IDE, Kiro CLI, Kiro on the web (preview on paid plans), ACP-compatible IDEs, and CI-oriented automation. Credits are shared across surfaces, no separate cloud-compute tax for web preview. - **VS Code Extension Compatibility.** Code OSS base means marketplace extensions, themes, and keymaps largely work. Teams migrate from VS Code/Cursor without rebuilding their entire editor stack. ## Install Kiro on Mac Kiro ships a native macOS app and CLI. Sign in with GitHub, Google, AWS Builder ID, or IAM Identity Center, an AWS account is optional for individual use. 1. **Download or install CLI.** Get the macOS build from kiro.dev/downloads, or install the CLI via the official installer script documented on kiro.dev. 2. **Install and sign in.** Open the DMG, drag Kiro to Applications, launch, and authenticate. Import VS Code settings/extensions if prompted. 3. **Create a first spec.** Open a repo and start a structured spec for a small feature. Watch credit usage in the subscription dashboard so Free-tier 50-credit limits do not surprise you. ## Pros - Spec-first workflow produces more reviewable, requirement-traceable agent output - Transparent credit pricing with Pro Max mid-tier and $0.04 overages - Strong AWS + IAM Identity Center enterprise path - VS Code-compatible editor reduces migration cost - Multi-surface subscription (IDE, CLI, web) on one credit pool - Free tier remains usable for light evaluation (50 credits + open weights) ## Cons - Credit forecasting is harder than flat unlimited-feeling plans, multi-agent runs can burn Pro quickly - Spec overhead slows pure vibe-coding compared with Cursor-style flows - Model lineup and credit multipliers shift with vendor announcements - Region/model availability caveats on premium Claude models - Team features and identity are AWS-shaped, less ideal if you want zero Amazon footprint ## FAQ ### How much does Kiro cost in 2026? Free is $0 with 50 credits/month. Paid individual tiers are Pro $20 (1,000 credits), Pro+ $40 (2,000), Pro Max $100 (5,000), and Power $200 (10,000). Add-on/overage credits are $0.04 each. Team plans mirror those prices with SSO and admin features. Confirm on kiro.dev/pricing before buying. ### Which AI models does Kiro use? Free: open-weight models (Qwen3 Coder Next, DeepSeek v3.2, MiniMax 2.1) and Claude Sonnet 4.5 with limits. Paid: Auto plus premium models including Claude Sonnet 4.6 and Claude Opus 4.8, with additional Claude versions selectable per docs. Not every premium model is available in every country. ### What is a Kiro credit? A credit meters work from prompts, spec refinement, task execution, and hooks. Simple prompts can cost under 1 credit; complex spec tasks cost more. Different models multiply cost (e.g. Sonnet 4.6 can be ~1.3× Auto for the same task). Metering goes to 0.01 credit precision. ### Do unused credits roll over? Monthly plan credits reset each billing month and do not roll over. Individually purchased add-on credit packs can roll for up to 12 months from purchase. ### Does Kiro require an AWS account? No for individual social login or AWS Builder ID paths. Team SSO and GovCloud flows use AWS IAM Identity Center / AWS accounts. You also do not need Amazon Q Developer solely to use Kiro. ### Kiro vs Cursor, which should I pick? Pick Kiro when you want specs, hooks, credit transparency, and AWS enterprise controls. Pick Cursor when you want the fastest free-form agent/tab loop and are fine with Cursor's usage-pool pricing. Many developers evaluate both at the $20 Pro tier. ### Is Kiro available on macOS Apple Silicon? Yes, native Mac downloads are supported for modern Apple Silicon Macs. Install from kiro.dev/downloads and keep the CLI updated alongside the IDE. ## Sources - [Kiro product home](https://kiro.dev/) - [Kiro pricing](https://kiro.dev/pricing/) - [AWS Kiro documentation overview](https://aws.amazon.com/documentation-overview/kiro/) - [Kiro vs Cursor 2026 comparison](https://www.augmentcode.com/tools/kiro-vs-cursor) - [RedMonk: Kiro and the AI IDE market](https://redmonk.com/sogrady/2026/06/23/kiro-ai-ide-market/) - [Kiro review 2026 (pricing verification)](https://aiagentsquare.com/agents/kiro) - [X: Kiro credit burn discussion](https://x.com/TeriRadichel/status/2085218865206993243) - [X: Kiro student Pro promo chatter](https://x.com/Atenov_D/status/2061721784244744619) ## Related - [Cursor](https://bundl.run/apps/cursor) - [Claude Code](https://bundl.run/apps/claude-code) - [ChatGPT](https://bundl.run/apps/chatgpt) - [Claude](https://bundl.run/apps/claude) - [Codex](https://bundl.run/apps/codex) - [Windsurf](https://bundl.run/apps/windsurf) - [Kiro vs Cursor](https://bundl.run/compare/cursor-vs-kiro) - [Kiro vs Trae](https://bundl.run/compare/kiro-vs-trae) - [Kiro vs Google Antigravity](https://bundl.run/compare/antigravity-vs-kiro) - [Free alternative to Cursor Pro](https://bundl.run/https:/) ```json { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://bundl.run/#organization", "name": "Bundl.run", "url": "https://bundl.run", "logo": { "@type": "ImageObject", "url": "https://bundl.run/og-image.png", "width": 1200, "height": 630 }, "description": "The Ninite for Mac.
