Kiro Pro costs $20/mo per user for 1,000 credits a month, and premium-model credits burn fast on real work. AWS added usage caps and a signup waitlist within days of the 2025 preview after a cost backlash, and AWS is now actively migrating Amazon Q Developer users to it.
GitHub Copilot Pro ($10/mo) is the cheapest capable alternative. Windsurf costs the same as Kiro Pro and includes Devin cloud agents. Factory is the pick if you liked Kiro for its test-and-review discipline.
| App | Free tier | Paid from | Top plan | Best for |
|---|---|---|---|---|
| Kiro | Yes | $20/mo | $200/mo | Teams already on AWS who want an agent that plans a spec and runs tests before generating code across large codebases |
| GitHub Copilot | Yes | $10/mo | $100/mo | Developers already living in VS Code/JetBrains/GitHub who want autocomplete, chat, and PR reviews without leaving their workflow |
| Windsurf (Devin Desktop) | Yes | $20/mo | $200/mo | Developers who want Devin's autonomous coding agent paired with a full IDE, not just a chat sidebar |
| Factory (Droids) | No | $20/mo | $200/mo | Engineering teams that want an agent-native workflow spanning coding, testing, review, and deploys, not just an IDE sidebar |
| Mistral Vibe | Yes | $14.99/mo | $24.99/mo | Users who want a privacy-conscious European alternative to ChatGPT/Claude with all-day agentic coding built in |
Monthly prices in US dollars before tax, from each vendor's official pricing (US list price; weekly-billed plans converted to a monthly figure). Updated November 2, 2026
Copilot Pro costs half as much as Kiro Pro and includes unlimited completions, 1,500 AI credits a month and agent mode with Claude, GPT or Gemini models.
Pick it if: you want everyday AI coding help at the lowest price.
Where it falls short: No spec-first planning, and agent mode trails dedicated agentic editors.
Full GitHub Copilot pricing →Windsurf Pro ($20/mo) includes full model access and Devin cloud agents that take whole tasks off your hands. Free has unlimited tab completions.
Pick it if: you'd rather delegate tasks to an agent than review a spec first.
Where it falls short: Heavier use pushes you to Max at $200/mo.
Full Windsurf (Devin Desktop) pricing →Factory's Droids write, test, review and deploy code across desktop, CLI and SDK, closer to Kiro's structured approach than an autocomplete tool. Pro is $20/mo per seat.
Pick it if: your team wants agents to own testing and review, not just code generation.
Where it falls short: No free plan, and higher-usage seats get expensive.
Full Factory (Droids) pricing →Mistral Vibe Pro ($14.99/mo) includes all-day agentic coding in the CLI, IDE or web, an everyday chat assistant and monthly API credits.
Pick it if: you want a coding agent and a general assistant on one bill below Kiro Pro's price.
Where it falls short: Free-tier limits aren't published as exact numbers.
Full Mistral Vibe pricing →Kiro's drafting of requirements and a design pays off on large, multi-step changes, but each step uses credits. If most of your work is small fixes and features, an edit-first tool like Copilot or Windsurf's tab completions will cost less per change. Keep the spec-driven approach for the big pieces of work, or check whether Kiro Free's 50 credits a month cover them.
Kiro has a free plan with 50 credits a month, open-weight models and Claude Sonnet 4.5, but it's rate-limited. Paid plans start with Pro at $20/mo per user.
Kiro is better at planning and testing large changes before writing code. Copilot is cheaper and better for day-to-day autocomplete and chat in VS Code or JetBrains.
