Kiro Pro and Claude Code both start at $20/mo. Kiro's $20 buys 1,000 credits and a model menu from open-weight DeepSeek and Qwen up to Claude Opus 4.7. Claude Code comes bundled with Claude Pro and runs Claude only, metered by a 5-hour window plus a weekly cap. This page lays out the credit math, the model lineups, and the spec-vs-terminal split with exact numbers.
Summary
| Dimension | Kiro (AWS) | Claude Code |
|---|---|---|
| Surfaces | IDE, CLI, Web, ACP-compatible IDEs | CLI, Desktop app (macOS/Windows) |
| Models | DeepSeek V3.2, Qwen3 Coder, MiniMax 2.1, Claude Sonnet 4.5 to Opus 4.7 | Claude only (Opus 4.8 top) |
| Core idea | Plan a spec before code | Headless autonomous execution |
| Metering | Credits (1,000/mo on Pro) | 5-hour window + weekly cap |
| Free tier | 50 credits/mo, open-weight models | Not included (needs Pro/Max/API) |
| Paid entry | Pro: $20/mo | Claude Pro: $20/mo (included) |
| Best for | Spec planning, model choice | CI/CD, automation, refactors |
The honest framing: Kiro and Claude Code overlap on price and both have a CLI, so the decision turns on two axes. First, model choice. Kiro is multi-model and Claude Code is Claude-only. Second, workflow. Kiro forces a written spec before code; Claude Code is built to run headless and automate end to end. A common 2026 pattern is Kiro to plan and prototype across cheaper open-weight models, Claude Code to automate the Claude-grade mechanical work in CI.
Pricing and Credits
| Tier | Kiro | Claude Code |
|---|---|---|
| Free | $0, 50 credits/mo, open-weight models + Sonnet 4.5 | Not included (free Claude.ai plan excludes Code) |
| Entry paid | Pro: $20/mo, 1,000 credits | Claude Pro: $20/mo (Code included; $200/yr annual) |
| Mid | Pro+: $40/mo, 2,000 credits | Claude Max: from $100/mo |
| Top | Power: $200/mo, 10,000 credits | Claude Max: $200/mo |
| Overage | $0.04 per credit, no rollover | Hit a wall until the window resets |
Kiro bills by credits. A simple prompt can cost less than 1 credit; executing a spec task costs more, and the model you pick changes the burn rate (Sonnet 4.6 runs about 1.3x the credits of Auto). Unused credits do not roll over, and overage is $0.04 per credit at month-end. New users get $20 credited toward a first upgrade.
Claude Code does not use credits. Usage runs against a 5-hour rolling session window (it starts at your first message) plus a weekly limit covering all models over 7 days, shared across claude.ai, Claude Desktop, and Claude Code on the same subscription. Anthropic-published guidance puts Claude Pro at roughly 40 to 80 active Sonnet hours per week; Max 5x ($100/mo) at roughly 140 to 280 Sonnet hours; Max 20x ($200/mo) at roughly 240 to 480 Sonnet hours or up to about 40 Opus hours. Active hours count processing time, not wall-clock.
How to read the $20 tiers
At $20/mo, Kiro gives you 1,000 metered credits and a model menu; Claude Code gives you Claude (up to Opus 4.8) within a time-windowed cap. If you run heavy autonomous Claude sessions, Claude Code's flat window can stretch further than 1,000 credits. If you want open-weight models or per-task cost control, Kiro's credits are explicit. See full pricing on the Morph pricing page.
Models and Providers
This is the sharpest difference. Claude Code runs Anthropic Claude models only, with Claude Opus 4.8 (released May 28, 2026, $5/M input and $25/M output via API) as the top option. There is no model switcher to a non-Claude provider.
Kiro is multi-model. The default is Auto, a mix of frontier models such as Sonnet 4.5. You can select Claude Sonnet 4.5, Sonnet 4.6, Haiku 4.5, Opus 4.5, Opus 4.6, or Opus 4.7. The free tier runs open-weight models: Qwen3 Coder Next, DeepSeek V3.2, and MiniMax 2.1. That makes Kiro the tool to reach for when you want to run DeepSeek or Qwen for coding without paying Claude rates.
| Kiro | Claude Code | |
|---|---|---|
| Open-weight models | DeepSeek V3.2, Qwen3 Coder Next, MiniMax 2.1 (free tier) | None |
| Anthropic models | Sonnet 4.5/4.6, Haiku 4.5, Opus 4.5/4.6/4.7 | Sonnet, Haiku, Opus 4.7/4.8 |
| Provider lock-in | No (model menu) | Claude only |
| MCP servers | Yes | Yes (http, sse, stdio) |
Spec-Driven vs Terminal Agent
Kiro's premise is that most AI coding failures come from skipping the plan. It writes requirements, a technical design, and a task list, gets your sign-off, then implements against that spec. On a complex feature this front-loaded rigor reduces rework. The cost is real: executing a spec task burns more credits than a one-line prompt, so spec mode is worth it on hard features and overkill on small edits.
Claude Code's premise is that the terminal is the universal interface. It reads your codebase, edits files, runs commands, and integrates with git from the CLI, which makes it ideal for headless automation and CI pipelines. Install with `curl -fsSL https://claude.ai/install.sh | bash` (or `brew install --cask claude-code`, `npm install -g @anthropic-ai/claude-code` on Node 18+). Native installs auto-update in the background. Add MCP servers with `claude mcp add --transport http notion https://mcp.notion.com/mcp`. Kiro also ships a CLI now (Kiro CLI alongside Kiro IDE and Kiro Web), so the line is no longer IDE-vs-terminal; it is spec workflow plus model choice vs Claude-only headless reach.
Benchmarks
Benchmark numbers track the model, not the wrapper. Kiro and Claude Code both run Claude, so on Claude they inherit the same scores; Kiro's open-weight options track their own.
| Model | Terminal-Bench 2.1 | SWE-bench Verified (self-reported) |
|---|---|---|
| Claude Opus 4.8 (Claude Code top) | 78.9% | 88.6% |
| Claude Opus 4.7 (Kiro top Claude) | 69.7% | 87.6% |
| GPT-5.5 (Codex CLI, for reference) | 83.4% | Not reported |
| Gemini 3.1 Pro (Gemini CLI) | 70.7% | 80.6% |
On Terminal-Bench 2.1, Codex CLI plus GPT-5.5 leads at 83.4%, Claude Code plus Opus 4.8 is second at 78.9%, and Gemini CLI plus Gemini 3.1 Pro sits at 70.7%. On SWE-bench Verified, Opus 4.8 leads published coding-agent models at 88.6%. If raw model score is the deciding factor, Claude Code on Opus 4.8 edges Kiro on Opus 4.7. If model choice and cost matter more, Kiro's menu wins.
Running Open-Weight Models for Coding
Kiro's free tier leans on DeepSeek V3.2, Qwen3 Coder Next, and MiniMax 2.1. The catch with open-weight models is serving quality: most serverless providers quantize activations to fp8 to cut cost, which degrades output versus the reference weights. Where you run the model matters as much as which model you pick.
Morph serves DeepSeek with 16-bit (bf16) activations, no fp8 or int8 quantization, so responses match the reference weights. For codegen specifically, Morph runs code-tuned speculative decoding (draft and ngram tuned on code) plus custom low-level inference kernels, which makes it the fastest and highest-quality way to run DeepSeek for coding agents. morph-dsv4flash (DeepSeek V4 Flash) is $0.139 per 1M input tokens and $0.278 per 1M output tokens. See the Morph Open Source Models and pricing.
| Typical serverless provider | Morph Open Source Models | |
|---|---|---|
| Activations | fp8 quantized (lossy) | 16-bit bf16 (reference fidelity) |
| Codegen tuning | General-purpose | Code-tuned speculative decoding + custom kernels |
| morph-dsv4flash price | Varies | $0.139/M in, $0.278/M out |
