Karma.Domains is the right tool for SEO professionals and domain investors who need deep archive-based spam analysis baked into their search workflow, not bolted on afterward. Its Karma Score and Wayback Machine content history set it apart from metric-only aggregators, but the API and MCP integrations that make it genuinely automatable cost $57.99 per month, a real jump from the $27.99 Unlimited tier. If your primary need is AI-driven content creation or on-page optimization rather than domain prospecting, every directory competitor here will serve you better.
What is Karma.Domains?
Karma.Domains is a domain intelligence platform for SEO specialists, link builders and domain investors. It aggregates expired, auction, backorder and buy-now domains from more than 40 sources, including GoDaddy, DropCatch, NameJet, Sedo, Dynadot and Namecheap, and adds hundreds of thousands of new domains every day. Each domain's history is analyzed through the Wayback Machine to detect spam, toxic topics, language and topic changes, redirects and server errors. The result is summarized in the proprietary Karma Score. Users can combine this with Ahrefs, Moz, Majestic, Semrush and SimilarWeb metrics in 90+ filters, read AI-generated history summaries, and automate searches through a public REST API, CLI, SDKs and an MCP server for AI assistants. The service also offers free SEO tools.
How we scored Karma.Domains
Capability scores high because the Wayback Machine spam analysis and Karma Score genuinely add a layer that metric-only aggregators like DomCop lack, and the 13M+ domain database with 40+ sources is among the largest in the category. Ease of use takes a hit because 90+ filters with no guided onboarding or preset templates is a real barrier for anyone not already fluent in expired domain research. Value is reasonable: the $27.99 Unlimited plan is competitive against Spamzilla at $37/month, and non-expiring credit packs are a fair model for occasional users, but the more than doubling of price to $57.99 for API access is a friction point that hurts the score for the developer audience. Delivery lands in the mid-range because the core product appears to do what it claims based on third-party reviews, but the proprietary and undocumented Karma Score algorithm is a transparency gap that makes it harder to fully trust the output, and no significant trust or consent issues were found.
Pros and cons
What we liked
- Wayback Machine spam analysis is built into every domain record, not a separate manual step, covering toxic topics, language drift, redirect history, and content category changes.
- Non-expiring credit packs ($14.99 for 99 credits, up to $27.99 for 400) let occasional users pay only for the reports they actually open, with no subscription pressure.
- MCP server and REST API support lets Pro subscribers query the full 13M+ domain database programmatically from AI assistants like Claude or custom scripts, a capability rare among expired domain tools.
Where it falls short
- API and MCP access are locked to the $57.99 Pro tier with no intermediate option; the jump from the $27.99 Unlimited plan to Pro is more than double the price for users who only need automation.
- The Karma Score is proprietary and its exact weighting is not publicly documented, which makes it harder to trust or calibrate against your own domain-quality criteria compared to transparent metric combinations.
- With 13M+ domains across 40+ sources, the filter interface is powerful but steep for newcomers; there is no guided onboarding flow or preset filter templates to help first-time users find a starting point.

Who should use Karma.Domains?
A link builder running a private blog network or building niche authority sites will get the most out of Karma.Domains. The Karma Score and Wayback content analysis answer the question that raw DR and DA numbers cannot: was this domain ever a pharma spam farm or a gambling redirect? Domain investors monitoring GoDaddy and Dynadot auctions daily will also find the Unlimited plan at $27.99 per month a reasonable cost for full database access, and the non-expiring credit packs work well for anyone who only dips into expired domain research a few times a month.
Agencies or developers who want to pipe domain data into their own tools or AI workflows need the Pro tier at $57.99 per month, which is the only plan with API and MCP access. If your work is primarily about optimizing existing content, building topical authority through writing, or tracking how your brand appears in AI search results, Karma.Domains is the wrong category of tool entirely. Surfer SEO covers content optimization and keyword-to-article workflows, and Corank handles AI search visibility, both of which are more directly useful for those jobs.
