Cheap backlink checker tools in 2026

Backlink tools at the top of the market cost $99 to $500 a month. Not everyone needs that. This page lists the free tools, the lifetime options, and the under-$50 subscriptions that are actually usable for real work, and says plainly where each one falls short.

"Cheap" is not one category. There is a free tier, a lifetime tier, and a budget subscription tier. Each trades something different for the lower price. Freshness, depth, and query limits are the usual three. If you know which of those matter for your work, you can pick the right tool in ten minutes.

Free tools

Google Search Console is free and gives you every link Google knows about pointing to domains you own. If you only need your own backlink profile, you do not need a paid tool at all. The limitations are that you only see your own sites and the UI is slow for bulk work.

Ahrefs, Moz, and SEMrush all run free backlink checkers with heavy limits: a few results per query, a handful of queries a day, and no export. Good for checking a single domain, not for real work.

Common Crawl is free and public. It contains the raw material almost every backlink tool is built on. Using it well requires a server, some storage, and comfort with SQL or data-processing tooling. It is technically the cheapest option and also the highest-effort.

Lifetime tier

Microcrawl — $99 once. Unlimited domain-level backlink lookups for a one-time payment. Data comes from the public hyperlink graph of the web, refreshed every quarter. Domain-to-domain only, no anchor text, no URL-level links, no keyword or SERP data. For prospecting, competitor scanning, and research, that is usually enough. For deep audits, it is not.

The trade on lifetime pricing is always freshness and depth. Microcrawl is honest about both. If daily data or per-URL anchor text matters to you, do not buy it. If it does not, $99 once beats a subscription by an enormous margin over five or ten years.

Under $50 a month

Majestic — $49 a month. The cheapest of the established SEO tools. Runs its own crawler, has a long historic index, and offers Trust Flow and Citation Flow metrics. URL-level data and anchor text are both included. Good middle-ground option if you want a real subscription tool and $49 is where you draw the line. See the Microcrawl vs Majestic comparison.

Ubersuggest — $29 a month, or a lifetime option. Bills itself as a budget all-in-one SEO tool. The backlink index is smaller than the big four, but at $29 a month it is priced for solo operators. Quality varies; try the free tier first.

Serpstat, Mangools, and similar budget suites. Each lands in the $30 to $50 a month range and each includes a backlink section. None of them match Ahrefs or Majestic on link index size, but for a solo user they often do enough.

Under $10 one-time or per check

A handful of smaller sites offer one-off backlink reports for a few dollars per domain. If you only ever need one report, these are genuinely the cheapest option. If you need five, Microcrawl is already cheaper in year one.

How to pick

The decision tree is short. If you need your own site's links, use Search Console. If you need a single one-off report, buy a per-report product. If you need ongoing domain-level lookups on any site, Microcrawl at $99 once is the cheapest real answer over any reasonable time horizon. If you need daily freshness, URL-level links, or anchor text, Majestic at $49 a month is the cheapest tool that actually delivers that.

The one warning: do not buy the cheapest subscription tool that meets none of your needs. A $29 tool whose data is three years old and whose index misses half the web is not cheap, it is wasted. Pay for something honest.

Why Microcrawl exists

The premium tools charge what they charge partly because SEO software has followed the rest of SaaS into per-seat, per-month, per-tier pricing. Running the underlying hyperlink-graph query is cheap. One rented server with DuckDB over public data handles a lot of traffic. Microcrawl is what happens when you strip away the sales team, the upsell funnel, and the four pricing tiers and just charge $99.

That is also why it does less. There is one person behind the product. Adding keyword research would require licensing data that costs real money per month. Adding daily freshness would require a much bigger crawl operation. Those features live in the paid suites for honest reasons. If you need them, buy them. If you do not, you should not have to pay for them.

Try before you buy

The free demo on the home page runs real lookups on real domains. It is capped at 20 rows per result and a few queries a day per visitor. That is intentional: enough to see whether the data is useful for your work, not enough to replace the paid product. If it looks right, buy it. If it does not, one of the tools above is a better fit.
