About Fish Catcher

Fish Catcher watches the address of every page you visit and explains, in plain language, when something looks like a phishing trick: 1.misspelled brand domains (micr0soft.com, paypa1.com) 2.look-alike characters from other alphabets (pаypal.com) 3.fake login pages hiding behind long subdomain chains 4.raw IP addresses and other classic tricks 5.Instead of a scary binary verdict, you get a clear risk level (low / elevated / high / critical) and the exact reasons behind it — so you learn to spot these tricks yourself. Fish Catcher never blocks, redirects, or modifies pages. An optional strict mode (off by default) can show a dismissible warning banner on risky pages. Privacy by design: analysis happens entirely on your device. No accounts, no analytics, no data leaving your browser. Open source (MIT) — the privacy promise is verifiable by reading the code. This tool uses transparent URL pattern analysis. No tool can guarantee a site is safe — always stay alert when entering passwords.
