About SEO Stack Tools

SEO Stack Tools is a free collection of SEO, content, image, conversion, and web-utility tools built to be genuinely useful for one-off tasks — the kind of thing you need done in two minutes without creating an account or hunting through ads.

Who Runs This Site

SEO Stack Tools is built and maintained by JayDev, an independent developer. It's a small, actively-maintained project rather than a large company — tools get fixed, added, and improved directly by the person running the site, and feedback submitted through the Contact page is read and acted on directly.

How the Tools and Content Are Built

The tools themselves run real conversion, calculation, and processing logic on the backend — not placeholder pages. Some content on tool pages (explanations, usage steps, and FAQ answers) is drafted with AI assistance and then reviewed and edited for accuracy before publishing. We believe in being upfront about that rather than pretending every word was typed by hand.

What You'll Find Here

• Content & Text Tools — Plagiarism Checker, Grammar Checker, Article Rewriter, Word Counter and more
• Keyword & SEO Tools — Keyword Position Checker, Backlink Checker, Domain Authority Checker, Meta Tags Generator

Why It's Free

The site runs on lightweight ads rather than subscriptions or paywalls, so tools stay free to use without an account for the vast majority of them. New tools get added when they're genuinely useful, not just to pad out a category page.
