Bot Signup Real-time Blocker

Detect and block disposable emails and scripted bulk signups at registration

Problem

Early-stage SaaS often get flooded with bot signups using disposable emails, wasting email quotas and polluting user data. Beginners discover it too late and lack simple real-time protection.

Solution

A lightweight JavaScript component and backend verification API for signup forms. It detects disposable email domains and anomalous registration behavior (multiple accounts from same IP in short time), automatically blocks or flags suspicious signups, and provides a dashboard with stats.

Users

Indie developers and small SaaS teams, especially early products lacking security experience.

MVP

Disposable email domain blacklist detection; IP/device rate limiting; frontend JS to collect behavior signals; backend verification API; simple dashboard.

Revenue

Subscription by signup checks: free 1k/month, $19/month for 10k; or per-site one-time license.

Why now

AI-generated content lowers bot signup costs and disposable emails are rampant; indie developers can quickly integrate existing blacklists and simple rules without complex risk systems.
