Why people compare these two platforms

SEO.Domains has been in the expired domain business since 2014. They run what they call the widest domain catching network in the world, accumulating 220,000+ domains in their portfolio. Around 20,000 are listed on their marketplace at any time, with human-written descriptions and niche categorization. They show Ahrefs DR, Majestic TF/CF, and Moz DA for each listing. Prices range from $30 to $60,000.

CatchDoms takes the opposite approach. Instead of buying domains and reselling them, we show you what's available right now on Dynadot, Catched, DropCatch, GoDaddy, and other platforms. You see 370,000+ domains with quality scores, language detection, and Wayback screenshots, then buy directly from the source.

The fundamental question is whether you want to pay a premium for curation or do the research yourself at source prices. SEO.Domains charges a markup because they've already done the work of catching, vetting, and categorizing. CatchDoms gives you the tools to do that work yourself for 468 EUR/year.

SEO.Domains also sells PBN link building services using their domain network, which positions them squarely in the grey-hat SEO space. CatchDoms is domain discovery only, with no link building services attached.

How CatchDoms works differently

CatchDoms is a subscription tool, not a marketplace. For 468 EUR/year you get unlimited access to 370,000+ domains from 7 registrars, each scored 0-100. Language detection covers 30+ languages automatically. Wayback screenshots show you what a domain looked like before it expired. The REST API and MCP integration let you build automations or query domains from AI assistants. You buy domains at source prices with no middleman markup.

Frequently asked questions

Different models entirely. SEO.Domains charges $30 to $60,000 per domain (one-time purchase, markup included). CatchDoms Pro costs 468 EUR/year for unlimited access to 370,000+ domains, and you buy at source prices from the original platforms. One is a marketplace with per-item pricing, the other is a subscription discovery tool.

SEO.Domains shows Ahrefs DR, Majestic TF/CF, and Moz DA per domain. CatchDoms shows Domain Authority, backlinks, referring domains, PageRank, Wayback data, and language, then combines them into a single 0-100 quality score. SEO.Domains shows more raw metrics; CatchDoms gives you an opinionated score so you don't have to evaluate each metric yourself.

They're ICANN-accredited, operating since 2014, and claim 6,400+ clients across 120 countries. That said, their Trustpilot reviews are mixed, with complaints about inflated prices and restrictive refund policies (only for proven spam penalties within 30 days). Do your due diligence on any domain purchase.

Potentially. SEO.Domains buys expired domains from auction platforms and marks them up. CatchDoms shows live listings from those same platforms before they're caught. Not every domain will overlap, but the supply chain is the same. With CatchDoms, you're earlier in the pipeline.
