zzyCaptcha

A simple, self-hostable, "persistence of vision" CAPTCHA service. This service generates animated GIF CAPTCHAs that are easy for humans to solve but difficult for bots to OCR. It provides a secure, backend-focused verification flow that is easy for developers to integrate into their websites. - Secure by Design: Verification is handled server-to-server, never exposing secret keys to the client. - Lightweight & Self-Contained: Uses a simple SQLite database, requiring no external database servers. - Easy to Integrate: Drop the widget into your form and verify submissions on your backend with a single API call. zzyCaptcha is the open-source project TianmuTNT/zzyCaptcha (https://github.com/TianmuTNT/zzyCaptcha) by TianmuTNT, released under Apache-2.0. Ion packages it unmodified from commit 8cdf0d681ab9, adding only a manifest, an icon and a start script.

Not rated. Nobody has said who this app is suitable for, so Personal Clouds and the Oikou app treat it as 18+.

Internet

It asks to reach nothing on the internet.

Personal Cloud tools

None. It uses nothing from your Personal Cloud beyond its own storage.

Notifications

It does not send push notifications.

Storage

Up to 512 MB on your Personal Cloud.

Its address

Works best with its own address. A Personal Cloud shared through Cloudflare can give it one; on a private Personal Cloud on Tailscale it opens under your Personal Cloud’s address, where it may not work fully. Private and shared Personal Clouds
