All Pro features, current and future, for this major version.

Checkout is not configured. Purchases open here once payments are set up; until then, start the 14-day trial from inside the extension.

What Pro adds

Mock responses. Return your own JSON, text or HTML for a matching API call while the backend isn’t ready. Responses come back with status 200.
Regex redirects with capture groups. Send ^https://cdn\.example\.com/app\.(\w+)\.js$ to http://localhost:3000/app.\1.js and debug production with your local build.
Shared variables. Write Bearer {{token}} once, use it in every profile, and change the token in one place.
Sync. Profiles and variables follow you through Chrome’s own sync storage. Headerbench runs no sync server.

Try every Pro feature free for 14 days, with no card. The trial starts the first time you add a Pro rule. If Pro lapses, Pro rules pause; nothing is deleted.

Questions

How do I activate?: After checkout this page gives you a licence key and a button that sends it to the extension. You can also paste the key in Headerbench under Settings. Lost it? Recover your key with your receipt email.
Do you see my rules?: No. They never leave your browser. The licence key is checked offline in the extension. The only request the extension makes is renewing a yearly licence.
Refunds?: 30 days, no questions, by replying to your receipt. See the refund policy.
Who handles payment?: Paddle.com is our reseller and merchant of record, and handles tax and invoices. Your receipt and invoice come from Paddle.
Can I buy for a team?: Each licence is for one person, on all of their own browsers. For several seats, buy one per person or write to support@headerbench.com.
