What is the best free backlink checker online?
Dev Utility offers a free backlink checker that lets you analyze external and internal links from your page HTML in your browser with no sign-up.
About Backlink Checker Online
Backlink Checker parses HTML you provide (or fetch when supported) to list external and internal links, anchor text, and rel attributes like nofollow.
SEOs use it for quick page-level link audits before publishing or after content migrations.
What is Backlink Checker?
Backlink Checker is a web-based utility in the BackLink Tools category. It is built for people who want reliable backlink results without installing plugins or creating accounts. The workflow matches how you already work: open a tab, paste or upload input, adjust options if needed, and copy or download the output.
On Dev Utility, backlink checker online is maintained alongside 5 other related tools so you can switch tasks without leaving the site. Each tool page includes the same privacy standards, responsive layout, and dark mode support, which makes the experience consistent across the catalog.
Backlink Checker is especially useful when you need a quick, repeatable process: the same steps every time, predictable output, and no learning curve for occasional users. Teams often bookmark individual tool URLs and share them in Slack, email, or documentation because the link always opens the exact utility—not a generic homepage.
Compared with desktop software, a browser-based backlink checker starts instantly, works across operating systems, and avoids license management. Compared with cloud upload services, client-side processing reduces exposure of sensitive documents and can be faster for small and medium files because data never round-trips through a remote datacenter.

Frequently asked questions
Does this crawl my whole site?
This tool analyzes one page HTML at a time. Use sitemap tools for site-wide crawls.

Live URL fetch limits?
Browsers block cross-origin fetches without CORS — paste HTML when fetch fails.
