FrostRank
Free SEO & developer tools — no signup, no paywalls
FrostRank is a free suite of SEO and developer tools that run entirely in your browser — no signup, no paywalls, no usage limits. Built by a working SEO engineer from real client audits, it covers technical SEO (JSON-LD schema generator, redirect chain checker, robots.txt validator, DNS lookup), developer utilities (JSON formatter, Base64 encoder, JWT decoder, HTML live preview), and everyday tools (QR code generator, password generator, invoice generator, word counter). Most tools process everything client-side, so your data never leaves your device. New tools ship regularly, free forever.

Hey everyone! I'm Rahib, a PHP/Laravel developer and technical SEO specialist. FrostRank started as a folder of internal scripts I kept rewriting during client SEO audits — a JSON-LD generator here, a redirect checker there. After the tenth time rebuilding the same thing, I decided to build them once, properly, and put them somewhere anyone could use for free. Every tool on the site solves a problem I actually hit on a real client site. There's no signup wall, no "Pro" upsell, and most tools run entirely in your browser so your data never touches a server. It's a one-person project and new tools ship whenever I run into a problem worth solving properly. Would love your feedback — what's missing, what's broken, what should I build next?
