MozBar Alternative: 5 SEO Extensions to Install Instead in 2026
Paul VengeonsCo-Founder & SEO ConsultantIn short
MozBar is still free, but it is rated 1.4 out of 5 by 2.5K users and Domain Authority needs a Moz account. For a free replacement, install the Ahrefs SEO Toolbar or SEOquake; keep a Moz Community account only if you need DA itself.
An extension tells you what is on a page. ChatSEO tells you which page to work on first, from your Search Console and live SERPs.

Which MozBar alternative is for you?
Answer 3 questions to find your SEO extension
π¬ How I compared the MozBar alternatives
I opened the Chrome Web Store listing of MozBar and of every extension below on November 13, 2026, and noted what each one gives without paying, what needs an account and what needs a subscription. I scored them on four things: what is free, the data you see on Google results, the on-page checks, and how much you can trust the numbers. ChatSEO is the company I co-founded, and its free extension is in this list: I rank it third, and I say what it does not do.
My take after years of SEO for clients: nobody needs Domain Authority on every page they visit. What you need is to see in one click why a page does not rank, and to check a competitor without opening a paid tool.
π§ Why people look for a MozBar alternative
MozBar is still free, but it has two problems in 2026:
- Its rating: 1.4 out of 5 from 2.5K ratings on the Chrome Web Store, for 900,000 users.
- Its tiers: a guest sees on-page elements and links only. Domain Authority and Page Authority need a free Moz Community account, and Spam Score, Page Optimization and keyword data need Moz Pro.
Moz rebuilt it from scratch as MozBar 5 in 2026, with 48 hours of caching to save your Moz Pro queries. If you only want DA, a free Moz account still does it. If you want an SEO toolbar that does more, read on.
π The 5 best MozBar alternatives (ranked)
| Rank | Extension | Price | Rating | Best for |
|---|---|---|---|---|
| 1 | Ahrefs SEO Toolbar | Free; Ahrefs metrics need a paid Ahrefs plan | 4.7 / 5 | On-page and link checks |
| 2 | SEOquake | Free; a free Semrush account adds Authority Score | 3.6 / 5 | Metrics on Google results |
| 3 | ChatSEO SEO Checker | Free | New, no rating yet | Why a page cannot be indexed |
| 4 | Detailed SEO Extension | Free | 4.8 / 5 | A fast look at the source |
| 5 | Keywords Everywhere | From $7 a month, billed yearly | 3.3 / 5 | Search volume everywhere |
1. Ahrefs SEO Toolbar: the best free MozBar replacement
The toolbar is free and covers what most people opened MozBar for: titles, meta descriptions, headings, canonical and indexing directives, link highlighting, redirect tracing and broken links, with CSV export. It also lets you switch Google's country and language without a VPN. Ahrefs metrics (keyword counts, traffic, referring domains) appear only for paid Ahrefs users. 400,000 users, 4.7 out of 5, updated on November 10, 2026.
2. SEOquake: metrics under every Google result
SEOquake is Semrush's free extension, used by 1,000,000 people. Its SERP Overlay puts position numbers and Semrush metrics under each organic result, and it now shows which pages Google's AI Overviews cite. A free Semrush account adds Authority Score, visits and engagement. It also has a page audit, a keyword density report and a side-by-side comparison of domains. Its rating is lower, at 3.6 out of 5.
3. 
ChatSEO SEO Checker: why a page cannot be indexed
Our free extension, published on November 11, 2026. It reads the page you are on and tells you whether Google can index it, with the reason when it cannot: status code, redirect chain, meta robots, X-Robots-Tag, robots.txt and canonical. It shows the title and meta description in characters and in pixels against Google's cut-off, the heading outline, links with their rel, images without alt and structured data. The analysis runs in your browser. It shows no Domain Authority and no backlink metrics: if that is why you used MozBar, pick option 1 or 2.

4. Detailed SEO Extension: the quickest look at a page
Free, 600,000 users and 4.8 out of 5. One click shows the title, meta description, meta robots, headings, schema and hreflang of the page you are on. It is made by Ahrefs too, and it does less than the toolbar, which is its point: it opens instantly.
5. Keywords Everywhere: search volume in Google and elsewhere
It shows search volume, cost per click and competition on Google and more than 15 other websites. It is paid with credits and billed yearly: Bronze is $7 a month ($84 a year) for 100,000 credits, and Silver is $14 a month for 400,000. Choose it for keyword data while you browse, not for on-page checks.

β Frequently asked questions
What is the best alternative to MozBar?
The Ahrefs SEO Toolbar for most people: its on-page, link and redirect tools are free, it is rated 4.7 out of 5, and it is available in 15 languages. SEOquake is the pick if you want metrics on every Google result.
Is MozBar still free?
Yes. Guest mode is free with on-page data, and a free Moz Community account adds Domain Authority and Page Authority. Spam Score, Page Optimization and keyword data need Moz Pro.
Why is MozBar rated so low?
Its Chrome Web Store rating was 1.4 out of 5 from 2.5K ratings on November 13, 2026. Moz rebuilt it as version 5 in 2026, and the store does not say which version the reviews are about.
Which extension shows Domain Authority for free?
Only MozBar, with a free Moz Community account, because DA is Moz's own metric. Ahrefs shows Domain Rating only to paid Ahrefs users, and SEOquake shows Semrush's Authority Score with a free Semrush account.
Can a free extension replace Moz Pro?
No. An extension reads one page at a time. For keyword research, backlinks across a whole site or rank tracking, you need a full tool, or Google Search Console for your own site.
Is ChatSEO free?
No. ChatSEO offers a 7-day trial with 30 credits, then plans start at β¬29 a month, or β¬23 a month billed annually. Its SEO Checker extension is free.
