Pricing
FreemiumKiro uses a credit-based Freemium model with five tiers and no daily or weekly rate limits. Credits are consumed fractionally per request \u2014 simple edits use fewer credits than complex spec-driven builds. Free tier includes limited credits with a restricted model selection (no Free tier in AWS GovCloud). Pro is $19/user/month, Pro+ is $39/user/month, Pro Max is $79/user/month, and Power is $199/user/month \u2014 each offering progressively more credits and model access. All paid plans include a $20 credit on first upgrade via social login or Builder ID (not IAM Identity Center). Add-on credits cost $0.04 each, available in packs from $5 (125 credits) to $100, rolling over for 12 months from purchase date. Enterprise pricing is custom via AWS sales and includes IAM Identity Center SSO, AWS PrivateLink VPC endpoints, admin governance controls, usage dashboards, cost management, IP indemnity, compliance features, and overage controls managed by admins. All active paid Kiro subscriptions also provide access to Amazon Q Developer IDE plugins during the transition window through April 30, 2027.
FreeCline itself is free and open source — there are no seat fees or subscriptions for the core agent. You pay AI inference costs directly to your chosen LLM provider (Anthropic, OpenAI, Google, etc.) with a full per-request cost breakdown shown in the UI. Cline shows every token used and every dollar spent transparently. ClinePass ($9.99/month) is an optional managed billing subscription that provides 2–5x more usage on popular open coding models compared to standard API rates, with one-click sign-in and no need to manage API keys yourself. It is not required — BYOK (bring your own key) is always available at zero markup. Enterprise pricing is custom and adds JetBrains extension, SSO/OIDC/SCIM, SLA, centralized billing, RBAC, team management dashboard, authentication logs, limit inference providers, dedicated support, VPC deployments, OpenTelemetry, and advanced config management.

Summary
Spec-driven agentic IDE by AWS — build what you mean, not just what you say
Open-source AI coding agent — any model, your keys, full control
Kiro

Kiro Pros & Cons

Pros

  • Only AWS-native agentic IDE — built and operated by AWS with the same security, reliability, and compliance standards trusted by millions of customers
  • Spec-driven development solves vibe coding's core problem: generating code that actually matches your intent, verified by property-based tests
  • Parallel agents work concurrently across the codebase — dramatically faster than single-agent coding tools for complex multi-file tasks
  • Broadest frontier model roster of any AWS developer tool — Claude Opus 5, Sonnet 5, GPT-5.6 (Sol/Terra/Luna), DeepSeek, and Auto routing
  • Unified agent harness across IDE, CLI, web, and mobile — one .kiro/ config works everywhere
  • Hooks enable fully automated SDLC workflows — documentation, tests, and standards enforcement on every file save or commit without interrupting flow

Cons

  • New product — released July 2025, less battle-tested than Cursor, Windsurf, or VS Code for large complex production codebases
  • Credit-based pricing model can be unpredictable — complex spec-driven builds consume credits faster than vibe coding
  • Spec-driven workflow has a learning curve; developers accustomed to chat-based copilots need to adapt to structured specs
  • Built on Code OSS, not full VS Code — some proprietary VS Code Marketplace extensions may not be available via Open VSX
  • Kiro Enterprise pricing is custom and sales-gated — no transparent list price for large team deployments
  • AWS GovCloud requires paid subscription with IAM Identity Center — no free tier in that environment
Cline

Cline Pros & Cons

Pros

  • Completely free and open source (Apache 2.0) — no seat fees, no subscriptions, no proprietary lock-in ever
  • 67K+ GitHub stars and 8M+ developers — largest open-source coding agent community by any measure
  • Full cost transparency at zero markup — the only major coding agent that shows exactly what you pay per request with no hidden pricing
  • Model-agnostic with 12+ provider integrations — switch any time without changing workflow or losing your setup
  • Plan/Act mode gives full human-in-the-loop control — approve every action or flip to autopilot when confidence is high
  • Trusted by engineers at Salesforce, Oracle, Amazon, Microsoft, eBay, Visa, IBM, and LG

Cons

  • BYOK means you manage your own LLM API keys and billing — can be confusing for non-technical users used to flat subscriptions
  • No built-in inline autocomplete (Tab completions) — Cline is an agent, not a code-completion tool like Copilot or Tabnine
  • JetBrains support is still Early Access — not as polished as the VS Code extension
  • Some engineers joining OpenAI's Codex team in January 2026 raised community concerns about long-term momentum (Cline confirmed no acquisition and remains independent)
  • Enterprise features (SSO, RBAC, JetBrains, SLA) require a custom sales contract — no self-serve team plan available
