Why these tools
We built them for the playbook we ran on Versely, our own product: clean metadata and canonicals, JSON-LD, an honest sitemap, llms.txt and open doors for AI crawlers. Each tool does one of those jobs, so you don't have to do it by hand or pay for a suite to do it once.
The checkers look at the live page the way a crawler does. Our server requests your URL, follows the redirects and reads the HTML and headers that come back. You see what Google and AI crawlers receive, not what your CMS settings say they should.
The AI writers run an open model on Cloudflare. Where a limit matters, like 60 characters for a title tag, we check the output against it before you see it. They write drafts. You still decide what ships.
Nothing needs a signup. Browser tools run on your device, and the rest work without an account or an email. When you're ready to put the site in front of people, launching here is free too.
Questions
Are these tools really free?
Yes. Every tool on this page is free and none asks for an account or an email. Tools that fetch a URL or call the AI model have a per-IP rate limit so one person can't use up the capacity for everyone. If you hit it, wait a moment and try again.
What do the URL checkers actually see?
They request the page from our server with a LaunchRankedBot user agent, follow redirects and read the HTML the server returns, like a crawler's first pass. They don't run JavaScript, so text that only appears after scripts run won't show up. That's worth knowing, because some crawlers don't run it either.
How do the AI tools work?
They run an open model (Meta's Llama 3.3 70B) on Cloudflare Workers AI, and the alt text tool uses a vision model. We check lengths and formats on what comes back, but the output is a draft. Read it and edit it before you publish.
Does what I paste leave my browser?
Not for tools marked In browser: they run on your device, so what you type isn't sent to us. URL checkers and AI tools send your input to our server, which fetches the page or runs the model and sends back the result. None of them needs an account.
Which tool should I start with?
Run the meta tag checker and the AI crawler checker on your homepage, then the sitemap checker on your domain. Those three catch the problems that stop pages being indexed or read by AI search. The workflow above lists the rest in order.
Where does the Domain Rating number come from?
From Ahrefs' free Domain Rating API. It's Ahrefs' metric, credited to them. If the API doesn't answer, the tool says DR is unavailable instead of estimating a number.
How is this different from launching on LaunchRanked?
The tools check and fix your own site. Launching gives you a permanent product page on LaunchRanked, a slot on the weekly leaderboard and a followed link after human review. No badge is required for the link.
