Free URL and Domain Tools: Parse, Redirect, Generate, and Verify

Master Your Web Addresses with Tools That Take Seconds

TL;DR: URLs and domains are the backbone of your online presence. Free tools for URL parsing, redirect tracing, domain WHOIS lookup, SSL checking, domain generation, and link unshortening help you manage, troubleshoot, and secure your web addresses. I use these daily for client site management and SEO audits.

A client called me in a panic because their website had dropped from page one to page four in Google overnight. No code changes. No content updates. Nothing obvious.

I ran a redirect check and found the problem: a migration script had created redirect loops on their top 15 pages. Page A redirected to Page B, which redirected back to Page A. Google couldn't crawl those pages, so they disappeared from results. The fix took five minutes. Finding the fix took the right tool.

URL Parsing and Analysis

URL Parser

The URL Parser breaks any URL into its components: protocol, hostname, port, path, query parameters, and fragment. I use it to debug tracking links (which parameter is the campaign source?), analyze competitor URLs (what's their content structure?), and troubleshoot API endpoints.

Paste a long URL with 12 query parameters, and the parser shows each one cleanly. No more squinting at a string of ampersands and equals signs.

HTTP Headers Parser

The HTTP Headers Parser shows the response headers from any URL. Headers reveal server type, caching rules, security policies, content type, and cookie settings. When debugging why a page loads slowly or why a CDN isn't caching correctly, headers tell the story.

HTTP Status Code Checker

The HTTP Status Code Checker returns the exact status code from any URL. Is the page returning 200 (OK), 301 (moved permanently), 404 (not found), or 500 (server error)? This is the first diagnostic I run for any page-level issue.

Redirect Management

Redirect Checker

The Redirect Checker traces the full redirect chain from any URL. If a link goes through three redirects before reaching its destination, this tool shows every hop. Redirect chains slow down page loading, confuse search engines, and can create loops.

That client with the redirect loops? This tool identified the problem in seconds.

HTACCESS Redirect Generator

The HTACCESS Redirect Generator creates redirect rules for Apache servers. When restructuring a site or changing URL patterns, proper redirects preserve search rankings and prevent broken links.

I generate HTACCESS rules for every site migration. Broken redirects are the most common SEO disaster after a redesign. More on this in my SEO audit guide.

Domain Intelligence

Domain WHOIS

The Domain WHOIS tool returns registration details: registrar, creation date, expiration date, and name servers. I check WHOIS data when evaluating domain purchases, verifying ownership, and monitoring expiration dates.

Domain Generator

Starting a new project? The Domain Generator suggests available names based on your keywords. Test multiple combinations before someone else registers the perfect name.

SSL Checker

The SSL Checker validates HTTPS certificates. Expired SSL causes browser warnings that terrify visitors and tank trust. I check client certificates monthly as part of my site maintenance routine.

URL Safety and Verification

URL Unshortener

Shortened URLs hide their destination. The URL Unshortener reveals where bit.ly, tinyurl, and other shortened links actually lead. Essential for security: never click an unfamiliar short link without checking first. More on URL safety in my data privacy guide.

URL Encoder and Decoder

The URL Encoder and URL Decoder handle percent-encoding for special characters in URLs. My encoding guide covers when and why you need URL encoding.

Website Health Checks

Website Status

The Website Status Checker confirms whether a site is online and responding. My first check whenever "the site is down" comes up. Half the time, the site is fine and the problem is local.

Source Code Downloader

The Source Code Downloader grabs the HTML source of any public page. I use it for competitive analysis: studying how top-ranking sites structure their markup, meta tags, and schema data.

Broken Link Checker

The Broken Link Checker finds dead links on any page. Broken links hurt SEO and user experience. I check client sites monthly as part of my standard SEO audit.

FAQ

What's the difference between a 301 and 302 redirect? A 301 is permanent. It tells search engines to transfer ranking authority to the new URL. A 302 is temporary, keeping authority on the original URL. Use 301 for permanent URL changes and 302 for temporary situations.

How often should I check for broken links? Monthly for active sites. Immediately after any site redesign, migration, or structural change. The Broken Link Checker focuses on individual pages; start with your highest-traffic pages.

Can I check if a domain is available without registering it? Yes. The Domain Generator and WHOIS lookup show availability. However, be aware that some registrars track lookups and may hold domain names. Research through multiple channels.

Why does my redirect chain have three hops? Common cause: you redirect HTTP to HTTPS, then www to non-www (or vice versa), then to a new page path. Consolidate into a single redirect that goes directly from the original URL to the final destination.

Is WHOIS privacy protection worth it? For personal domains, yes. It hides your name, address, and phone number from public WHOIS databases. For business domains, it depends on whether you want the company details publicly visible.
