Why these tools
Built for launch SEO, not vanity dashboards
Most SEO suites bury founders in crawl reports. These tools answer the questions you actually hit the week before launch: What’s this directory’s Domain Rating? How does my landing page compare with a competitor’s? Will my meta description be cut off? Can ChatGPT and Perplexity read my site? Which ISO week am I launching in?
Pair them with a launch on ShipX. Every product gets a permanent, indexable page with a dofollow link to your site, in a weekly cohort of makers who, like you, don’t have a big audience yet. The authority you earn there keeps compounding after launch day.
Comparing two sites? Start with SEO Compare. Only need authority? Use the Ahrefs DR checker. For the full playbook, read how to launch a SaaS and the best Product Hunt alternatives.
Questions
Free SEO tools FAQ
What free SEO tools does ShipX offer?
73 tools across authority, branding, on-page and technical SEO, Markdown and content, and launch week, including a GEO / AI citation checker, Ahrefs DR checker (single and bulk), on-page SEO audit, SEO Compare, PageSpeed Insights, WHOIS and domain age, a ten-tool sitemap suite, robots.txt and llms.txt generators, a UTM builder and an interactive SaaS launch checklist.
Are these tools really free?
Yes. Every tool is free with no account. Tools that fetch other websites or call upstream APIs (Domain Rating, PageSpeed, SEO audits, sitemap fetches, link checks) are rate-limited per visitor so they stay fast and fair for everyone.
What's in the sitemap suite?
A finder and checker, validator, link counter, URL extractor, XML sitemap generator, sitemap index generator, split / merge, compare, analytics and a changefreq / priority analyser. Start with the sitemap checker, then add the Sitemap: line to robots.txt.
Where does the Domain Rating data come from?
Live from Ahrefs' free public Domain Rating API, attributed as “Domain Rating by Ahrefs”. Results are cached for 24 hours.
What's the best way to compare two websites?
Use SEO Compare: it audits both pages with the same checks (title, meta, H1, canonical, Open Graph, structured data, indexability, speed) and adds each site's Ahrefs DR side by side.
Do you store the URLs or text I enter?
Browser tools (generators, converters, text analysis) never send your input anywhere. Checkers that need a server fetch the URL you give them, return the result and don't keep it.
Who are these tools for?
Indie makers and small SaaS teams preparing a launch: naming the product, shipping on-page SEO, checking a directory's authority before submitting, and planning launch week, without paying for an enterprise SEO suite.
How should I use them before launch?
Follow the workflow on this page: validate the idea, ship on-page SEO, check authority against competitors and directories, then run the launch checklist. When you're ready, launch on ShipX for a permanent product page with a dofollow link to your site.
Tools done. Launch next.
Launch free on ShipX: a permanent product page with a dofollow link to your site, a weekly leaderboard that resets, and makers who are exactly where you are.
- Free to launch, no audience required
- Dofollow link from your product page
