The Kiro alternative for agent-built products

If you're searching for a Kiroalternative, you've probably already hit the edge of what it does well. We build IntentDocs — one of the alternatives — so read this knowing that. We'll also tell you when the honest answer is to stay put.

Choose Kiro if you want spec-driven development as a complete AWS-backed IDE — spec, code, and review in one surface. Choose IntentDocs if you're keeping Claude Code or Cursor and want the spec as a separate, visible layer they connect to over MCP, priced flat instead of by credits.

Why people look for a Kiro alternative

• Adopting Kiro means switching IDEs, not adding a spec layer to the tools you already use.
• Specs are trapped inside the IDE — a founder or PM who doesn't run Kiro can't see or shape the plan.
• Credit-metered pricing makes cost per feature hard to predict, and heavy tiers run to $200/user/month.
• If your team is split across Claude Code, Cursor, and other agents, an IDE-shaped tool can't be the shared spec layer.

First: when you should stay with Kiro

Kiro is AWS's agentic IDE built around specs. Describe a feature and it generates structured requirements, a design document, and a task list, then implements task by task, with agent hooks automating quality checks along the way. It's the most complete single-surface experience in spec-driven development — the whole loop of spec, code, and review inside one opinionated IDE.

None of that stops being true because you're shopping. Stay if:

• You want the entire loop — spec, implementation, review — inside one opinionated IDE.
• You're happy to switch editors, or you're not attached to your current agent.
• Built-in agent hooks for automated quality checks matter to you.
• AWS backing and enterprise controls are a factor in your tooling decisions.

IntentDocs as the Kiro alternative

IntentDocs is a spec-driven development platform: an AI interview turns your idea into a structured spec — a visual story map, data model, and build order — and your coding agent (Claude Code, Cursor, or any MCP client) builds from it over MCP, with an audit trail of what was built versus what was planned.

Against the reasons people leave, that means:

• You're committed to Claude Code, Cursor, or another agent — IntentDocs adds a spec layer without asking you to move editing house.
• Planning needs to be visible to people who will never install an IDE: founders, PMs, clients.
• You want flat pricing rather than estimating credit burn per task.
• You want the spec to outlive any one editor — it lives independently and any MCP client can connect.

Pricing

IntentDocs: 7-day free trial, no card required. Pro is £12/month (or £120/year, equivalent to £10/month). Team is £15 per seat/month (or £144/seat/year), minimum 2 seats. Enterprise is custom. Details on the pricing page.

Kiro (August 2026):

• Free: $0 — 50 credits/month, access to open-weight models and Claude Sonnet 4.5
• Pro: $20/user/mo — 1,000 credits
• Pro+: $40/user/mo — 2,000 credits
• Pro Max: $100/user/mo — 5,000 credits
• Power: $200/user/mo — 10,000 credits
• Enterprise: Custom — Centralised billing, SSO, usage analytics

Kiro meters usage in credits — a unit of work whose burn rate varies with task complexity and model choice; add-on credits cost $0.04 each.

Other alternatives worth considering

IntentDocs isn't the only option, and depending on your shape of problem it may not be the right one. CodeGuide (spec and context generator), ChatPRD (AI PRD platform for product managers), GitHub spec-kit (open-source spec-driven development toolkit).

The honest verdict

Kiro is the most complete spec-driven environment you can buy, and if you want one surface for the whole loop with AWS behind it, it's a genuinely strong choice. The cost is that the workflow lives inside Kiro. IntentDocs makes the opposite bet: keep the editor and agent you've already chosen, and let the spec be the shared, visible layer that any MCP client connects to — with an audit trail of what got built.

Frequently asked questions

Is Kiro free? There's a free tier with 50 credits/month including access to Claude Sonnet 4.5. Paid plans run $20 to $200 per user/month by credit volume, with add-on credits at $0.04. IntentDocs is £12/month flat after a 7-day trial — no metering.

Does Kiro work with Claude Code or Cursor? No — Kiro is its own IDE with its own agent; adopting it means moving your editing workflow into it. IntentDocs takes the opposite approach: it's a spec layer your existing agent connects to over MCP.

Kiro vs spec-kit vs IntentDocs — quick version? Kiro if you want spec-driven development as an all-in-one IDE. spec-kit if you want free, open-source markdown specs in your repo. IntentDocs if you want an interview-built visual spec that your current agent builds from over MCP, with built-vs-planned tracking.

Can a non-developer use Kiro to plan? In practice, no — Kiro's specs live inside a developer IDE. If founders, PMs, or clients need to read and shape the plan, a visual story map in the browser (IntentDocs's approach) is the more workable surface.
