# Karma.Domains Review An expired domain aggregator that scores every domain's Wayback Machine history for spam, toxic topics, and content drift across 13M+ ## Editor's Score: 72/100 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 - 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. ## Cons - 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. ## Pricing Freemium. A free tier is available. - Free (signup credits): Free - Credits (99): $14.99 - Credits (200): $19.99 - Credits (400): $27.99 - Unlimited: $27.99/mo - Pro: $57.99/mo Pricing reflects what we saw at the time of review (2026-10).

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. Best for: SEO link builders and domain investors vetting expired domains for spam history Not for: Teams needing AI content optimization or on-page SEO guidance ## Overview Karma.Domains is an expired domain aggregator built around one core idea: that knowing a domain's SEO metrics is not enough if you do not know what the domain was actually used for. Every domain in its database of 13M+ listings gets a proprietary Karma Score derived from Wayback Machine analysis, which checks for spam content, toxic topic categories like gambling or pharmaceuticals, language shifts, redirect chains, and server errors across the domain's full archive history. That is the differentiator. Tools like DomCop or Spamzilla surface backlink counts and authority scores; Karma.Domains adds a content-history layer on top. The platform pulls from 40+ auction sources including GoDaddy, DropCatch, NameJet, Sedo, Dynadot, and Namecheap, and processes 400,000+ new domains every day. Users filter across 90+ parameters combining Ahrefs DR, Moz DA, Majestic TF/CF, SimilarWeb traffic, and Wayback-derived signals like language, domain age, and content category. AI-generated history summaries give a plain-language read of what a domain was before it dropped. The free tier gives new accounts 5 credits to test reports without a card. Beyond that, the model splits into non-expiring credit packs for occasional buyers and monthly subscriptions for active researchers. The catch: the REST API, MCP server, CLI, and SDKs that make Karma.Domains useful inside automated workflows or AI assistants like Claude are gated behind the $57.99 Pro plan. That is a meaningful price step for solo operators who only need the web interface. ## Who should use it 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. ## FAQ Q: Is there a free trial or free plan? A: New accounts receive 5 credits at signup with no credit card required. These credits can enable individual domain reports to test the platform before buying a credit pack or subscription. Q: What is the Karma Score and how is it calculated? A: The Karma Score is a proprietary metric derived from Wayback Machine archive analysis. It penalizes domains for spam content, toxic topic categories, abrupt theme changes, language shifts, and redirect or server error patterns. The exact weighting formula is not publicly documented. Q: Do credits expire? A: Credits purchased in any of the three credit packs ($14.99, $19.99, or $27.99) do not expire. The 2,000 credits included with the Unlimited monthly plan are tied to the 30-day subscription period. Q: Which plan includes API access? A: Only the Pro plan at $57.99 per month includes the Public REST API, MCP server, and CLI. The Unlimited plan at $27.99 per month and all credit packs exclude API and MCP access entirely. Q: How many domains does Karma.Domains cover and how often is it updated? A: The database holds over 13 million domains across 40+ auction sources, with 400,000+ new domains processed every day. Statistics on the homepage are updated daily, with the live count showing over 421,000 domains added in the most recent 24-hour window. Q: Can I use Karma.Domains with AI assistants like Claude? A: Yes, but only on the Pro plan. The MCP server integration lets AI assistants query the domain database directly. Pro also includes SDKs in Python, PHP, JavaScript, Go, and other languages for custom automation.
