Fill signup forms with realistic fake data, temp-mail inboxes, and OTP verification. Built for developers and QA testing in Chrome.

FakeSignup is a free Fake Filler alternative for developers and QA testers. Auto-fill signup forms with realistic fake data, create a disposable temp email, and catch OTP codes and verification links without leaving your tab. Looking for fakefiller, a random data generator or a test data form filler that also handles email verification? FakeSignup is a form filler, dummy data generator and temp mail inbox in one Chrome extension. Fake Filler style autofill stops at the submit button. FakeSignup covers the whole registration flow: fill the form, receive the confirmation email, read the OTP or 2FA code, and save the test account. WHAT FAKESIGNUP DOES Smart form autofill: Detects signup fields from labels, placeholders, autocomplete attributes, ARIA attributes and Shadow DOM, so it fills forms built with React, Vue, Angular and web components. Realistic dummy data: Generates fake names, usernames, emails, phone numbers, addresses and strong passwords for every fill. Built-in disposable email: Creates a temporary inbox in one click and attaches it to the form. There is no separate 10 minute mail tab to open, refresh or copy from. OTP and verification link extraction: Listens for the incoming email, pulls out the one-time passcode or verification code, ranks the activation links, and lets you copy either with one click. Test account manager: Saves the email, password and username for each site so you can reuse logins for regression testing. Full Auto batch mode (Premium): Fill, submit, confirm the email, save the login and repeat. Create up to 100 accounts per run for seed data, staging environments and load testing. BUILT FOR SIGNUP FLOW TESTING Test registration end to end. Run through signup, email confirmation and first login in one browser tab, for manual QA and for building test fixtures. Works on any signup form. Use the click-to-map field picker for unusual forms, custom components and multi-step flows, and set success and error text so Full Auto knows when a run worked. Export test accounts to JSON (Premium) to feed Playwright, Cypress, Selenium or any test setup you already use. Control your test data. Set custom first and last name fixtures when you need predictable values. HOW IT WORKS Fill tab: Click Fill Signup Form.
