Expired domain tools and checkers (free and paid)

Finding a good expired domain without the right tools is like shopping blindfolded. You need to know a domain's age, backlinks, spam history, and whether it's even worth the price. Some tools cost $100+/month. Others are free and surprisingly capable.

Here's a practical breakdown of the tools that actually work for finding, checking, and evaluating expired domains in 2026.

Expired domain search tools

These tools help you find expired domains across multiple registrars and auction platforms.

CatchDoms

Price: Free (limited) / Pro from 39 EUR/mo
Best for: searching across multiple platforms with SEO data

CatchDoms pulls expired domains from 9 sources (GoDaddy, DropCatch, Catched, Dynadot, and more) and enriches every domain with SEO metrics: Domain Authority, Trust Flow, Citation Flow, referring domains, Wayback age, detected language, and a quality score from 0 to 100.

The free tier shows 10 domains with blurred names. Pro unlocks everything: full access to 370k+ domains, CSV exports, saved searches with email alerts, API access, and an MCP server for AI-assisted workflows.

What sets it apart: you search once across all platforms instead of checking each registrar separately. Each domain links directly to the auction or purchase page, so there's no middleman.

ExpiredDomains.net

Price: Free (with ads) / Member area for extra features
Best for: large-scale research, bulk lists

The longest-running expired domain tool. It lists domains from most major registrars and shows basic metrics like Wayback age, backlinks (via Majestic), and domain length. The interface looks like it was designed in 2010, but the data is solid.

Downsides: no quality scoring, limited filtering compared to newer tools, and the data updates can lag by a few hours. You'll need to cross-reference with other tools (Ahrefs, Majestic) for a complete picture. See our detailed CatchDoms vs ExpiredDomains.net comparison.

SpamZilla

Price: from $37/mo
Best for: PBN builders who need spam detection

SpamZilla focuses on filtering out spammy domains. It scores domains on a spam scale and provides Majestic metrics (TF, CF, topical trust flow). Good if your primary concern is avoiding penalized domains.

Limited to domains that have already dropped (no auction listings). The database is smaller than ExpiredDomains.net or CatchDoms. See our detailed CatchDoms vs SpamZilla comparison.

DomCop

Price: from $49/mo
Best for: power users who want Moz, Majestic, and Ahrefs data in one view

DomCop aggregates data from multiple SEO providers and lets you sort by PA, DA, TF, CF, and Ahrefs metrics. Good filtering options. The higher-tier plans include pre-filtered "power lists" of high-quality domains.

Expensive for casual users. The cheaper plan limits how many domains you can view per day. See our detailed CatchDoms vs DomCop comparison.

Domain checker tools (free)

Once you've found a domain you like, use these free tools to verify it before buying.

Wayback Machine (web.archive.org)

Price: Free
Checks: archive history, content over time, age

Non-negotiable for any expired domain purchase. Enter the domain and see every archived snapshot going back to the early 2000s. You're looking for:

• Consistent content over time (same topic, same owner)
• No spam or adult content periods
• First snapshot date (this is the real domain age, not the WHOIS date)
• Gaps in archiving (may indicate the domain changed hands)

Google Search (site: operator)

Price: Free
Checks: Google indexation, possible penalties

Search site:domain.com on Google. For a recently expired domain, some pages might still be indexed. If the domain has strong backlinks but zero indexed pages, it could carry a penalty. Not definitive (Google drops expired domains from the index naturally), but a useful signal.

Ahrefs free backlink checker

Price: Free (limited)
Checks: top backlinks, referring domains, DR

Ahrefs offers a free backlink checker at ahrefs.com/backlink-checker. It shows the top 100 backlinks, total referring domains, and Domain Rating. Enough to get a rough picture without a paid subscription. For deeper analysis, you'll need the full tool.

Majestic (free tier)

Price: Free (limited) / from $49/mo
Checks: Trust Flow, Citation Flow, topical trust flow

Majestic's free lookup gives you Trust Flow and Citation Flow for any domain. The TF/CF ratio is one of the fastest ways to assess link quality: ratio above 0.5 is clean, below 0.3 is suspicious. The paid version adds topical trust flow categories, which tells you what niche the domain's backlinks come from.

WHOIS lookup

Price: Free
Checks: registration dates, registrar history

Any WHOIS tool (whois.domaintools.com, who.is) shows when the domain was first registered, when it last changed hands, and which registrar manages it. Useful for verifying that the domain's registration history matches what you see in the Wayback Machine.

How to use these tools together

Here's the workflow that takes about 5 minutes per domain:

1. Search on an aggregator: use CatchDoms with a quality filter to find candidates. Filter by score 50+, age 5+, and "has backlinks" to remove junk.
2. Quick metrics check: look at DA, TF/CF ratio, and referring domains directly on the listing. Skip anything with TF below 10 or fewer than 20 referring domains (unless it's very cheap).
3. Wayback Machine: check archive history. Look for consistent content and no spam periods. 10+ years of clean history is ideal.
4. Backlink deep dive: for domains that pass the first three checks, run them through Ahrefs or Majestic to inspect anchor text distribution and referring domain quality.
5. Google check: search site:domain.com to verify indexation status.
6. Buy or bid: if everything checks out, click through to the registrar and complete the purchase.

What to look for (cheat sheet)

Free vs paid: is it worth upgrading?

You can find and evaluate expired domains using only free tools. Wayback Machine, Google's site: operator, and free tiers of Ahrefs and Majestic cover the basics. The catch is speed: checking each domain manually across 4-5 tools takes 10-15 minutes. If you're buying one domain, that's fine.

If you're buying regularly (weekly or more), a paid tool like CatchDoms Pro pays for itself by putting all the data in one place. Filter 370k+ domains by score, age, backlinks, and language in seconds. Set up saved searches with alerts so you don't miss deals. Export to CSV for offline analysis. The time savings add up fast.
