Signup Tester - Temp Mail & OTP | FakeSignup

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

Auto-fill signup forms with realistic dummy data, generate disposable temp email, and catch OTP codes instantly in one tab. FakeSignup is the ultimate form filler and dummy data generator built specifically for developers, QA testers, and product teams. Unlike basic form fillers that only insert static dummy text, FakeSignup automates the entire registration flow: realistic data generation, disposable temporary email, real-time OTP code extraction, and test account management - all without leaving your current tab. If you are looking for a modern alternative to Fake Filler or manual copy-pasting from 10-minute mail tabs, FakeSignup streamlines your manual and automated QA testing end-to-end. KEY FEATURES Smart Form Auto-Fill: Auto-detects input fields across complex architectures including Shadow DOM, modern component libraries, labels, ARIA tags, and HTML5 autocomplete attributes. Realistic Dummy Data: Generate contextual mock data for names, phone numbers, addresses, usernames, and secure passwords. Built-In Disposable Temp Mail: Spins up a temporary inbox instantly to receive activation emails without third-party tabs or throwaway accounts. Instant OTP & Link Extraction: Detects incoming verification emails, extracts OTP/2FA verification codes, and highlights activation links directly in the UI. Local Test Account Manager: Automatically saves created credentials per domain/URL into secure local storage for seamless regression testing. Full Auto Batch Mode (Premium): Loop automated signups for load testing or seed accounts. Fill, submit, verify email, and save accounts hands-free (up to 100 runs). WHY DEVELOPERS & QA PREFER FAKESIGNUP OVER GENERIC FILLERS End-to-End Registration Testing: Generic form fillers leave you hanging once the form is submitted. FakeSignup receives the confirmation email and extracts the verification code inside the extension pop-up. Shadow DOM & Framework Friendly: Accurately maps dynamic forms generated by React, Vue, Angular, and web components. Exportable Test Fixtures: Export saved QA testing accounts directly to JSON for automated testing frameworks (Playwright, Cypress, Selenium). FEATURE BREAKDOWN Fill Tab: One-click dummy data fill, instant temp-mail attachment, live OTP listener, and quick-copy buttons for all generated fields. Inbox Tab: Clean ephemeral email viewer with one-click inbox refresh and link ranking to prioritize confirmation links over generic text. Accounts Tab: Persistent site-by-site account store. Free tier includes up to 10 accounts; export to JSON available on Premium. Full Auto Mode: Click-to-map selector, error detection, automated submission, and background loop execution. FREE VS. PREMIUM PLANS Free: 15 fills per day, 5 active disposable email inboxes, 10 local saved accounts, custom name fixtures. Premium: Unlimited form fills, unlimited temporary email inboxes, Full Auto batch signups, automated form submission, JSON test-suite export, and 60-minute background email listening. PRIVACY & SECURITY FakeSignup values developer security. Generated temporary mailboxes are completely ephemeral.
