3. Preparation Checklist (Zero Barriers)
Before you begin, get these two "pieces of gear" ready:
- A Gmail or GitHub account that has never registered for Kiro
- Note: it must be a new account; existing accounts can't join the $0 promotion.
- Pro stacking trick: if your Google account already registered with Kiro before, try registering a brand-new GitHub account with that Google account, then authorize Kiro login with the new GitHub account — it'll be recognized as a new user.
- A credit card that supports foreign-currency payments
- Domestic dual-currency cards (with Visa, Mastercard, etc.) work in practice — it's just card verification and won't be charged immediately.
- Easy alternative: if you'd rather not bind a card or worry about privacy, you can buy a $0 virtual card for a few yuan on marketplaces like Xianyu (Used Fish) or Taobao. It's tested and fully works — quick, easy, and no worry about forgetting to cancel a renewal later.
4. Core Steps: How to Use Claude Opus 4.7 for Free (Full Illustrated Walkthrough)
Step 1: Register and Log In to Kiro Web

Open Kiro's web login: https://app.kiro.dev/signin
On the page, simply choose Google login or GitHub login and authorize in one click to enter the system.
Step 2: Pick a Plan and Trigger the $0 Checkout

After logging in, you'll be taken to the Subscription page automatically. Here you'll see different tiers — read carefully:
- Option A: pick the $20 tier (pure freebie, recommended!) The referral campaign credits $20 directly, so the actual amount due is
$0.00— you get the first month of Pro for free. - Option B: pick the $40 tier (better for heavy users) If you're a high-frequency power user, choose the Pro+ tier. After Kiro's $20 discount, you only pay a small difference and get 2x the Pro Credits.
Once you've decided, click the "Upgrade to Pro" button under the corresponding tier.
💡 Key anti-pitfall tip: on the payment/checkout page, make sure to check the total on the left or in the sidebar. If it shows
$0.00, the $20 discount has applied successfully — that's what you want! If it asks for $20, go back and check whether your account qualifies as a new user.
Step 3: Enter Your Card Details and Complete the Subscription

Fill in your real dual-currency credit card or virtual card details on this page, then confirm the subscription.

After submitting, wait a few minutes and refresh your Kiro subscription page. As soon as you see 1,000 Credits in your account, the subscription is complete!
At this point, the core mission of "how to use Claude Opus 4.7 for free" is done. Open the Kiro client, switch to Claude Opus 4.7, and enjoy extreme coding and Q&A efficiency powered by AI.
Step 4: Cancel Auto-Renewal
The peak of getting something for free is "get on safely, exit gracefully." If you bound your real credit card, to avoid being charged $20 next month because you forgot, cancel auto-renewal right after the subscription succeeds.
Here's the exact path:

- Go to Kiro's usage and billing management page: https://app.kiro.dev/account/usage
- Click Manage Plan.
- Downgrade back to Kiro Free and confirm.
🎉 Safe-to-do guide: many beginners hesitate to cancel right away. Rest assured — under Kiro's billing rules, after canceling renewal, your first-month Pro membership and 1,000 Credits remain fully valid for the rest of the month; they won't be terminated early. When the next cycle arrives, your account simply auto-downgrades to the free plan — a truly 100% safe exit with zero charges.
