Referral Autofill

Referral Autofill helps you never leave referral money on the table. When you visit the signup page of a supported rewards or referral program, it shows a small banner with your own referral code ready to copy — if you choose to use it. Nothing is ever inserted or applied automatically, and it stays out of the way when a referral or affiliate marker is already present on the page. Disclosure-first by design: every banner clearly states that the code benefits the person who shared it, and you decide whether to use it. The extension makes zero network requests, collects no data, and all settings and statistics stay on your device. It supports popular two-sided referral programs across banking, shopping, crypto, and fantasy sports. The full list of supported programs lives in the extension's options page, where you can add your own codes and links. Free to use. No account required.
