Free Ahrefs Alternatives (2026): What Actually Replaces It, Honestly
Search “free Ahrefs alternative” and you’ll get a wall of listicles promising a magic tool that does everything Ahrefs does for nothing. That’s not honest, so we won’t pretend. We use Ahrefs every day for client work, and we can tell you plainly: no free tool replaces all of it. What you can do — and what this guide is actually about — is figure out which specific job you were using Ahrefs for, then cover that job with a free or low-cost tool. Do that across a few tools and you get most of the way there for a fraction of the cost.
The trick is to stop thinking of Ahrefs as one thing. It’s really five jobs bundled together, and the free route works well for some of them and poorly for others.
What Ahrefs actually does (so you know what to replace)
Before you shop for an alternative, be clear about which part of Ahrefs you actually rely on. Most people use two or three of these, not all five:
- Keyword research — finding search terms, volumes, and difficulty scores.
- Backlink analysis — seeing who links to a site and how strong those links are. This is Ahrefs’ historical strength; its index is one of the biggest. (If terms like Domain Rating or Authority Score are new to you, it’s worth understanding what those authority metrics actually measure before you lean on them.)
- Competitor research — what a rival ranks for, where their traffic comes from, and where the content gaps are.
- Site audits — crawling a site for technical problems.
- Rank tracking — monitoring your positions over time.
Here’s the honest split: the free route is strong for keyword ideas, your own site’s data, and technical audits. It’s weak for competitor backlink analysis, because that’s exactly the data that costs money to collect and maintain. Keep that in mind as you read.
The honest truth about “free”
Free SEO tools come in three flavors, and the differences matter:
- Genuinely free forever — Google Search Console, Google Analytics 4, Ahrefs Webmaster Tools, Google Keyword Planner. These are the backbone. They’re limited in scope but not in time or credits.
- Free tiers of paid tools — Semrush, Moz, Mangools, Serpstat all let you do a small number of lookups per day before they wall you off. Useful for spot checks, frustrating for real work.
- Free up to a limit — Screaming Frog crawls 500 URLs free, which covers a lot of small sites entirely.
The single most important thing to understand: no free tool has a backlink index the size of Ahrefs’. That index is expensive to build and maintain, and it’s the main thing you’re paying for. Free tools give you a slice of link data — enough for your own site, rarely enough for deep competitor analysis.
The stack at a glance
Here’s how the free and low-cost options compare for replacing Ahrefs, job by job. Prices shift, so treat them as ballpark.
| Tool | Best for | Cost | The catch |
|---|---|---|---|
| Google Search Console | Your own rankings & indexing | Free | Your verified sites only |
| Ahrefs Webmaster Tools | Your own backlinks & site audit | Free | Your verified sites only |
| Google Keyword Planner | Keyword ideas & volume ranges | Free | Needs a Google Ads account; volumes are banded |
| Screaming Frog | Technical site audits | Free to 500 URLs | Desktop app; no backlink data |
| Ubersuggest | Keyword research on a budget | Free tier / low paid | Thin backlink & competitor data |
| Mangools | Friendly all-round research | ~$29/mo, trial | Smaller index than Ahrefs |
| Moz (free tools) | Quick authority & link checks | Free tier | ~10 free queries/mo, then paid |
| Semrush (free account) | All-in-one spot checks | Free tier | ~10 requests/day cap |
Job by job: what to actually use
Keyword research. This is where free works best. Google Keyword Planner is free (you need a Google Ads account, but you don’t have to run ads) and gives you real Google volume ranges. Ubersuggest and the free tiers of Mangools and Semrush add difficulty scores and related-term ideas. For most small sites, this combination covers keyword research completely.
Your own site’s backlinks and health. Sign up for Ahrefs Webmaster Tools — it’s free, and it gives you a genuine slice of Ahrefs’ data for any domain you can verify in Search Console. It’s the closest thing to “free Ahrefs” that exists, precisely because it is Ahrefs, just limited to sites you own. Pair it with Search Console for the ranking and indexing side.
Competitor backlinks. This is the honest weak spot. Free tiers of Moz Link Explorer and Semrush let you check a competitor’s links, but only a handful of times before they cap you. There’s no free tool that gives you deep, repeatable competitor link analysis — that’s the one job where, if it’s central to your work, Ahrefs or Semrush paid genuinely earns its cost.
Technical audits. Screaming Frog’s free version crawls up to 500 URLs and finds broken links, redirect chains, duplicate titles, and missing metadata. For a small business site, that’s often the whole audit, free.
Rank tracking. Search Console shows your average positions for free, which is enough for many small sites. If you need daily, exact, competitor-aware tracking, that’s a dedicated-tool job — we broke down the options in our comparison of the best daily rank tracking software, including which ones are genuinely affordable.
So what should you actually use?
The decisive calls:
- Best free tool overall, and non-negotiable: Google Search Console. Real data straight from Google about your own site.
- Closest thing to “free Ahrefs”: Ahrefs Webmaster Tools — real Ahrefs data for sites you own.
- Best free keyword research: Google Keyword Planner, backed up by Ubersuggest or a free Mangools trial.
- Best free technical audit: Screaming Frog (free to 500 URLs).
- Best cheap all-rounder: Mangools or Ubersuggest if you want one low-cost paid tool instead of juggling free tiers.
- Where free genuinely runs out: deep competitor backlink analysis. If that’s core to your work, budget for a paid tool. When you get there, our Semrush vs Ahrefs comparison walks through which of the two big suites fits which kind of work.
A realistic free stack — Search Console, Ahrefs Webmaster Tools, Google Keyword Planner, and Screaming Frog — will run a competent SEO program for a small site at zero cost. Step up to a paid tool when competitor intelligence and a bigger backlink index start to matter more than the money saved. If you’re weighing a full paid platform for agency-scale work, we compared those in the best SEO software for agencies.

FAQs
Is there a truly free alternative to Ahrefs?
Not one tool that replaces all of it. Ahrefs bundles a huge backlink index, keyword research, competitor analysis, site audits, and rank tracking, and no single free tool matches that whole package. What you can do is cover most of the individual jobs with a stack of free tools: Google Search Console and Ahrefs Webmaster Tools for your own site’s data, Google Keyword Planner for keyword ideas, Screaming Frog for audits, and the capped free tiers of Semrush, Moz, or Mangools for spot checks. It’s more manual, but for a small site it works.
What’s the best free tool for checking backlinks?
For your own site, Ahrefs Webmaster Tools is the best free option — it gives you a real slice of Ahrefs’ backlink index for any domain you can verify in Search Console, at no cost. For checking competitors’ backlinks, the free options are thin: Moz’s Link Explorer and Semrush both allow a small number of free lookups per day, but you hit the cap fast. Serious competitor backlink work is where the free route runs out and a paid tool earns its price.
Can I do SEO without paying for Ahrefs?
Yes, especially on a small site. Google Search Console and Google Analytics 4 are free and give you the most important data — what you actually rank for and what converts. Add Screaming Frog’s free tier for technical audits and Google Keyword Planner for keyword ideas, and you can run a competent SEO program without Ahrefs. The paid tools mainly buy you competitor intelligence, a bigger backlink index, and time saved at scale.
What’s the closest free tool to Ahrefs overall?
The free tiers of Semrush and Mangools give the closest all-in-one feel — keyword research, some backlink data, and site audits under one login — but both are heavily capped (Semrush allows only a handful of free requests a day). For your own site specifically, Ahrefs Webmaster Tools is the closest thing to real Ahrefs data because it is Ahrefs data, just limited to domains you own.
Is Ubersuggest a good cheap alternative to Ahrefs?
For keyword ideas and basic site audits on a budget, yes — Ubersuggest is inexpensive (and has a limited free daily allowance), with a friendly interface aimed at beginners and small businesses. Where it’s weaker is backlink data and competitor depth, which is exactly where Ahrefs is strongest. If your main need is keyword research and content planning rather than deep link analysis, Ubersuggest is a reasonable, cheaper pick.
