Built it for myself, thought someone else might want it too.

Simple one-click Chrome extension that aliases your email at every signup, so when spam shows up you know exactly which site leaked it.

Click the icon on any signup page:

  netflix.com  →  you+netflix.com@gmail.com
  amazon.com   →  you+amazon.com@gmail.com

Plus addressing works on Gmail, Google Workspace, Outlook, ProtonMail, Fastmail and others. Handy at companies running Workspace.

Workspace users with a custom domain can also use catch-all mode:

  ted.com        →  ted.com@firstlast.com
  wikipedia.org  →  wikipedia.org@firstlast.com

Different from forwarding services like SimpleLogin, Firefox Relay, or Apple Hide My Email: nothing sits in the mail path. The extension just generates the alias, your existing provider handles delivery. If Apple ever discontinues Hide My Email, every alias you made with it stops working. Clean-Autofill has no service to shut down. No accounts, no servers, no analytics. All local. Open source.
