the cheapest option depends on the research and exports you need. a free preview may be sufficient; crawlgraph also offers a lifetime license at $99 paid once and a monthly option to eligible visitors. the seven subscription amounts below are retained assumptions from this article's september 2026 comparison, not verified current quotes. use the arithmetic to compare software costs after checking each vendor's current plan, currency, billing period and feature eligibility.
the question has two honest answers
a subscription amount of $129 a month would cost $1,548 over twelve months of monthly billing, before tax or discounts. if what you open it for is a referring-domain list twice a week, compare the cost of that specific job. the useful question is not which tool is best, it is what the smallest amount of money is that still gets you the link data. if you want the free end of that range first, start with how to find backlinks for free and come back here when you hit the export limits.
using only the retained amounts, spyfu has the lowest subscription figure in this table at $39/mo. crawlgraph's current lifetime offer is $99 once. neither establishes the cheapest eligible option available today. in this illustrative comparison, cost parity occurs in month 1 against ahrefs and month 3 against spyfu, and then it is $0 for as long as you keep using it.
the retained subscription-cost assumptions
the figures used by the original comparison. they are not a current entry-tier audit. the right-hand column calculates how many months of that subscription add up to $99 paid once.
| their subscription | crawlgraph, $99 once | |
|---|---|---|
| Ahrefs | $129/mo, $1,548/yr | cost parity in 1 month |
| Semrush | $140/mo, $1,680/yr | cost parity in 1 month |
| SE Ranking | $103/mo, $1,238/yr | cost parity in 1 month |
| Moz | $99/mo, $1,188/yr | cost parity in 1 month |
| Serpstat | $69/mo, $828/yr | cost parity in 2 months |
| Majestic | $50/mo, $600/yr | cost parity in 2 months |
| SpyFu | $39/mo, $468/yr | cost parity in 3 months |
3 of the seven cost less in a single month than crawlgraph costs in total, and moz costs exactly the same. this compares the retained amounts, not equivalent capabilities or current entry plans. lower tiers, annual billing, discounts, taxes and currency can change the result.
the cheapest option is $0, up to a point
worth saying before any of the paid arithmetic: the floor for this query is free, and it is a real floor rather than a seven-day trial. the backlink gap analysis runs without an account, just an email, and returns your first 5 gaps; free runs are capped per ip address. a free api key gives you 15 backlink lookups a month. any domain returns its top 5 referring domains without an account. no card, no countdown.
paid access expands the available referring-domain result slice instead of the top 5. csv and json exports are capped at 100,000 rows per domain, with the total count reported separately. free api access allows 15 backlink calls and no gap jobs per utc month; paid api access allows 1,000 backlink calls and 50 gap jobs. check current api limits and available plans. if your real usage is one competitor check a month, the honest answer to “what is the cheapest ahrefs alternative” is $0, and you should not pay us either. the lifetime plan is for the point where you want the rows out in bulk.
the break-even arithmetic
break-even is one division: $99 divided by the competitor's monthly price, rounded up to the next whole month.
- semrush, $140/mo - 1 month.
- ahrefs, $129/mo - 1 month.
- se ranking, $103/mo - 1 month.
- moz, $99/mo - 1 month.
- serpstat, $69/mo - 2 months.
- majestic, $50/mo - 2 months.
- spyfu, $39/mo - 3 months.
using the retained assumptions, the longest cost-parity interval on the list is 3 months. twelve months at $129/mo is $1,548 versus $99, a difference of $1,449. year three is $4,644 versus $99. even against spyfu at the assumed $39/mo, three years would be $1,404 versus $99.
the fair objection to any lifetime price is that lifetime means the company's lifetime, not yours. worth saying plainly: crawlgraph is a thin layer over the public common crawl hyperlink graph, the methodology is published rather than proprietary, and paid available result slices export to csv or json. if we disappeared tomorrow the underlying dataset would still be free and public, and your exports would still be on your disk. that is a weaker promise than a company that will obviously outlive you, and a stronger one than a lifetime deal built on data only the vendor can see.
the arithmetic only holds if the cheap tool does the job you bought it for. that is the next section, and it is the part most cheapest-alternative posts skip.
what you give up when you cancel ahrefs
an all-in-one suite can serve several research jobs. crawlgraph's$99 lifetime option focuses on backlink intelligence; it does not replace all the suite's capabilities.
- rank tracking. gone completely. crawlgraph does not track a single keyword position. if you need daily positions, buy a rank tracker.
- site audit. gone. no crawl of your own site, no broken-link report, no technical issue list.
- keyword research. gone. no search volumes, no difficulty scores, no serp history, no content gap by keyword.
- a continuously refreshed index. ahrefs runs its own crawler and re-crawls constantly. crawlgraph reads the common crawl hyperlink graph, roughly 121.1M domains and 3.90B links. new links become queryable after a verified graph is imported; no next-day discovery guarantee applies to either source in this comparison.
- the cleanup layer. de-duplication, anchor normalization, spam filtering, re-validating that links are still live. common crawl publishes the graph as it found it, and we do not add a cleanup pass on top.
who should not switch
stay where you are, or buy a cheaper suite rather than a one-off backlink tool, if any of these describe you:
- you report weekly rank movement to a client or a boss. that is a rank tracker job and nothing on the lifetime-plan side of this page does it.
- keyword research is what you actually open the tool for. compare current suite plans for keyword data and rank tracking; crawlgraph does not provide those features. for ppc and competitor ad intelligence, evaluate the relevant vendor's current capabilities and limits separately.
- you need new-link and lost-link alerts within days of them happening.
- you need a particular vendor's authority metric in client reports. crawlgraph's stored authority percentile is not interchangeable with it.
choose the tool that serves the job before comparing quotes. a lower price does not compensate for missing a feature you require.
who the lifetime plan is for
the profile is narrow and worth stating precisely:
- the thing you open ahrefs for is the list of domains linking to a competitor.
- you look at it monthly, or per campaign, not hourly.
- you want the rows out of the tool: csv or json, into a sheet, a sequencer, or a script.
- the subscription cost exceeds the value of the research you use.
if those describe your workflow, compare a specialist tool with the suite using your actual quotes and target domains. inspect a result before paying, and try the gap-analysis preview if overlap research is the job you need.
one practical note before you cancel anything: export what you cannot get back. check the vendor's retention and export terms for saved projects and tracked history before changing plans. an open-graph snapshot can supply recorded referring domains, but it cannot recreate another vendor's historical observations. inspect the retained seo-tool overlap example and its limits before assuming the datasets are interchangeable.
the verdict
in the retained model, the lowest subscription assumption is $39/mo, or $468 for twelve monthly payments. crawlgraph's current lifetime amount is $99, giving illustrative cost parity in 1 month against the assumed $129/mo and within 3 months against the other retained amounts. this is software-cost arithmetic, not a current cheapest-plan ranking or measured return on investment. verify present quotes, plan eligibility, currency and required features before choosing. further product-fit comparisons sit on the free ahrefs alternative page.
