What it is
Kiro is an agentic AI IDE and CLI from AWS that uses spec-driven development (requirements → design → tasks) to turn prompts into production-ready code, docs, and tests.
Gabriel’s notes
Quick take: Kiro is AWS’s attempt to domesticate “vibe coding” by putting a spec in front of the code. I haven’t put it through my own paces yet, but the workflow is intriguing—and the pricing is at least in the same universe as Cursor.
Kiro is an agentic AI development tool that ships as both a standalone IDE and a CLI. Its headline feature is spec-driven development: you start with a natural-language prompt, Kiro turns that into structured requirements and acceptance criteria (including EARS-style phrasing), then helps generate an architecture/design and a sequenced implementation plan, and finally executes tasks to produce code, docs, and tests. It also supports agent hooks (automation on events like file save), steering/config files for “your code, your rules,” and native MCP integration for connecting to external systems.
My original note to self still stands, with one small correction: this isn’t “just another vibe-coding toy.” It’s explicitly trying to add a paper trail (specs, tasks, acceptance criteria) so your future self—and your teammates—don’t have to reverse-engineer what the agent was thinking at 2:00 a.m.
I saved this under Dev & code because it’s a developer-facing workflow tool first, and a chatbot second.
Good fit if you want to:
- Turn a fuzzy prompt into explicit requirements + acceptance criteria before any code changes happen.
- Break large builds into discrete, trackable tasks that map back to the spec (aka “less wandering, more shipping”).
- Automate repeatable dev chores with hooks (docs, tests, lint-y cleanups) triggered by events like saving a file.
- Use an agentic workflow in an IDE and from the terminal via a CLI.
- Keep tighter control over spend with credit-based metering and visible per-prompt usage.
Pricing snapshot (auto-enriched):
Kiro has a Free tier ($0/month) that includes 50 credits, plus a new-user bonus of 500 credits usable within 30 days. Paid tiers are Pro ($20/month for 1,000 credits), Pro+ ($40/month for 2,000 credits), and Power ($200/month for 10,000 credits). Paid plans can enable overages at $0.04 per additional credit (off by default).
Work-use / compliance snapshot (auto-enriched):
Kiro positions itself as built on AWS security infrastructure and documents a shared-responsibility model for how you should secure your environment and data. AWS’s documentation overview for Kiro also notes enterprise options such as customer-managed keys for encryption. Beyond that, the exact data-retention, training-use, and admin/audit controls for your scenario should be treated as Unknown / not confirmed until you review the specific Kiro docs, your plan level, and your org’s policies.
Alternatives (auto-enriched):
- Cursor — another AI-first coding editor with a popular $20/month Pro plan; tends to feel closer to “AI-native VS Code” than “spec-first process tool.”
- Claude Code — Anthropic’s terminal-native agent; great if you prefer a CLI-centric workflow and want the agent to run locally with permission prompts rather than living inside a dedicated forked editor.
Before you adopt it:
- Confirm extension compatibility: Kiro is Code OSS–based and supports VS Code settings/themes plus Open VSX–compatible plugins—so treat your favorite Marketplace extensions as “trust, but verify.”
- Do a small pilot and measure credits per real task (not per prompt) so you can predict monthly cost.
- Decide where agent automation is allowed (hooks can be powerful; they can also be chaos in a trench coat).
