50 Free SEO & Developer Tools
A collection of 50 free browser-based tools — SEO previews, text utilities, calculators, and generators — built directly into this site.
What it is
A set of 50 small, focused tools covering SEO previews, text transforms, calculators, and generators — everything runs client-side in the browser, nothing is stored on a server, and there's no signup.
Why I built it
These are the kinds of tools I reach for constantly in SEO and development work — a Google SERP preview, a slug generator, a JSON formatter — so I built a proper version of each and made them free for anyone visiting the site.
How it's structured
A config-driven registry defines each tool's metadata and SEO title/description, with a shared "transform" engine covering the simpler text tools so the collection can keep growing without duplicating code for each one.
