Best MozBar Alternatives 2026: 7 Free SEO Toolbars Compared

Published on September 4, 2026 by Steven Jones

The best MozBar alternative depends on which part of MozBar you are actually replacing. Some SEOs use it to inspect titles, headings, canonicals and links. Others mainly want Domain Authority and backlink context. A third group keeps it installed for the Google SERP overlay.

Those are three different jobs, and no free extension is automatically best at all of them. We checked the current public feature sets of the leading SEO browser extensions on 4 September 2026, separating genuinely free functions from features that require an account, credits, or a paid subscription. Detailed SEO Extension is our best overall free replacement for fast page inspection, Ahrefs SEO Toolbar is stronger for authority and backlink-led research, and SEOquake remains the better choice for a free SERP overlay.

One current detail is worth clearing up first: MozBar itself is not an abandoned legacy extension. Moz rebuilt MozBar V5 in 2026, adding a faster framework, new caching, a configurable interface and expanded technical checks. The case for replacing it is therefore about workflow fit, data preferences and paid-feature dependency rather than MozBar simply being obsolete.

MozBar is really three tools in one

Replacing MozBar starts by identifying the job that would be missing if you uninstalled it. MozBar currently combines three useful layers:

• Page inspection: titles, descriptions, headings, canonicals, robots directives, schema and link highlighting.
• Authority and link data: Domain Authority, Page Authority and other Moz metrics, with more data available through Moz Pro.
• SERP research: authority and link metrics placed beside Google results, with export options for comparison work.

MozBar itself also has access tiers worth separating. Guest mode covers basic on-page elements and internal-link information; a free Moz Community account adds DA and PA; and Moz Pro opens the full set of metrics, such as Spam Score, page optimisation, domain analysis, and keyword-ranking queries.

A lightweight inspector can replace the first job without paying for a large SEO database. It cannot calculate Domain Authority or Domain Rating locally because those scores depend on an external link index. Likewise, a keyword-data extension can make Google results far more useful while still being weak at canonicals, HTTP headers, or redirect chains.

This explains why the strongest setup is often two small tools rather than one supposed all-in-one replacement. Practitioner discussions repeatedly converge on the same pattern: keep one fast inspector for page checks and add one data-heavy extension only when you need authority, backlinks or query metrics.

How we compared the seven alternatives

We compared the current documented capabilities rather than treating installation alone as proof that a tool is free. The checks covered metadata, headings, canonical and robots handling, schema, hreflang, redirects, broken links, nofollow highlighting, backlink and authority metrics, estimated traffic, keyword data, SERP overlays, export options, account requirements and browser support.

We did not invent browser-speed benchmarks. A proper performance comparison would need the same browser profile, extension versions, pages and network conditions. Our comments on clutter refer to how much persistent toolbar or SERP UI each extension adds, not a claimed millisecond load-time result.

Page and technical inspection

Tool	Metadata and headings	Canonical / robots	Schema / hreflang	Redirects / broken links	Nofollow checks	Export
Detailed SEO Extension	Strong	Robots and X-Robots checks; canonical is not a headline feature in current documentation	Strong	Limited compared with a redirect tracer	Yes	Links and images
Ahrefs SEO Toolbar	Strong	Strong	Strong	Strong, including full redirect chains and broken outgoing links	Yes	Links and SERP data
SEOquake	Strong	Robots and site checks are included; not our first choice for canonical debugging	Limited specialist depth	Link analysis, but not our first choice for redirect tracing	Link-type analysis	Yes
Keywords Everywhere	On-page keyword analysis rather than full technical inspection	Not a core feature	Not a core feature	Not a core feature	Not a core feature	Paid bulk and research workflows
Mangools SEO Extension	Strong on-page layer	On-page checks included, but not positioned as a canonical or robots specialist	Structured data included	Not a redirect specialist	Yes	Not the main strength
SEO Meta in 1 Click	Strong	Strong basic checks	External rich-result tooling rather than deep built-in validation	No dedicated chain tracer	Limited	Limited
SEO Pro Extension	Strong	Strong	Schema included	Strong redirect-chain checks	Yes	Headings, links, images and page copy

Authority, keyword and SERP data

Tool	Authority / backlink metrics	Traffic estimates	Keyword metrics	SERP layer	Account needed for useful free functions?	Browser support	UI footprint
Detailed SEO Extension	No proprietary metrics	No	No query-volume database	PAA extraction, not a full authority overlay	No	Chrome, Firefox	Low – mainly click-to-inspect
Ahrefs SEO Toolbar	DR/UR with free sign-in; fuller backlink metrics on paid access	Paid metric layer	Free ideas; deeper metrics on paid access	Yes	No for technical checks; sign-in for DR/UR	Chrome, Firefox, Safari	Medium – metrics bar and SERP tools can be toggled
SEOquake	Page, domain and backlink panels	Data-source dependent	Strong on-page keyword analysis	Strong	No	Chrome, Firefox, Edge, Opera	High by default – configurable toolbar and SERP overlay
Keywords Everywhere	Free Moz DA and backlink data	Free website traffic metrics	Free difficulty and ideas; paid volume, CPC and trends	Strong query widgets	No free features	Chrome, Firefox, Edge	High in SERPs – multiple widgets add visible data
Mangools SEO Extension	DA, PA, CF, TF and backlink data with an account	Not its main browser-extension advantage	Account-backed keyword data	Strong	No for on-page checks; yes for richer metrics	Chrome, Firefox	Medium – compact extension with optional SERP enhancements
SEO Meta in 1 Click	No	No	No	No	No	Chrome	Low – compact inspector
SEO Pro Extension	No	No	No	No	No	Chrome	Low – click-to-inspect rather than persistent SERP overlay

1. Detailed SEO Extension – best overall free MozBar alternative

Detailed is the easiest recommendation for an SEO who opens MozBar mainly to inspect the page in front of them. It is fully free and exposes headings, X-Robots information, schema, hreflang, links, image URLs and other page-level details without requiring a subscription.

The workflow is particularly good for editorial and technical spot checks. You can copy headings, inspect structured data, review hreflang references and status codes, highlight nofollow links, export links or image URLs, and switch the user agent to see a page as Googlebot. It can also extract People Also Ask results from Google.

The limitation is fundamental rather than fixable: Detailed does not operate its own large backlink or keyword database. It can send the page into external tools, but it does not replace Moz DA, Ahrefs DR or a true SERP authority layer by itself.

Choose Detailed if: you want the cleanest free replacement for MozBar’s on-page and technical inspection functions and do not need proprietary link metrics on every page.

2. Ahrefs SEO Toolbar – best MozBar alternative for authority and backlink research

Ahrefs SEO Toolbar is the closest alternative for users who treat MozBar as a research layer rather than a metadata viewer. Its free technical features are unusually broad: title and heading inspection, canonicals, robots directives, hreflang, structured data, image alt text, outgoing link checks, local SERP simulation, user-agent switching, and full redirect chains, including JavaScript redirects.

Ahrefs also improved the free data proposition. Its current product page states that a free sign-in can reveal a site’s Domain Rating and URL Rating. Paid access unlocks the full metric layer, including backlinks, referring domains, estimated organic traffic, ranking keyword counts, and richer SERP metrics.

The hidden cost is usage accounting. On paid accounts, requesting page or SERP metrics can consume Ahrefs export rows. A conventional ten-result SERP can consume ten rows when result metrics are loaded, and keyword metrics can consume another row. Anyone leaving the overlay switched on during heavy research should understand that before treating the toolbar as a passive unlimited dashboard.

Ahrefs is also available across Chrome, Firefox and Safari, giving it the broadest desktop-browser support in this shortlist. If you are trying to replace the wider Ahrefs platform rather than only MozBar, use our full Ahrefs alternatives comparison instead.

Choose Ahrefs SEO Toolbar if: authority, backlink context, redirects and SERP research all matter, and you are comfortable signing in or paying when you need the deeper data layer.

3. SEOquake – best free MozBar alternative for SERP overlays

SEOquake makes the strongest case when the feature you miss is MozBar’s SERP overlay. It can add SEO data to search results, run a page audit, examine internal and external links, compare domains or URLs and export results to CSV without requiring a paid subscription.

That breadth is useful for quick competitive scans. The trade-off is interface density. SEOquake exposes far more controls and data than a minimalist page inspector, so it is better as an extension you configure around a research task than one you allow to fill every search page indiscriminately.

There is another reason not to follow its audit output mechanically. SEOquake’s current diagnosis documentation still references checks such as meta keywords and AMP alongside more useful technical checks. Treat the raw information as evidence and set priorities yourself, rather than assuming every flagged item has equal SEO value.

Choose SEOquake if you want a genuinely free SERP overlay, CSV exports, and fast domain or URL comparisons without buying a complete SEO suite.

4. Keywords Everywhere – best for keyword and Moz metrics inside Google

Keywords Everywhere has become a more credible alternative to MozBar than its name suggests. Its free extension now includes website traffic metrics, Moz link metrics such as Domain Authority and backlink data, SEO difficulty, related keyword ideas and on-page keyword analysis. You do not need an API key just to use those free functions.

Paid plans add the data people still most strongly associate with Keywords Everywhere: search volume, CPC, competition and historical trend information. That makes the extension particularly useful for someone who uses Google itself as the centre of the keyword-research workflow.

It is not a substitute for a proper technical inspector. Canonical debugging, HTTP headers, redirect chains and hreflang validation are better handled by Detailed, Ahrefs or SEO Pro. It also places more information directly into search interfaces, which can become visual noise if your main goal is simply to inspect the current page.

Choose Keywords Everywhere if: your MozBar habit is mostly about checking authority alongside Google results and you also want keyword or traffic context in the same browser workflow.

5. Mangools SEO Extension – best simple extension linked to a wider SEO suite

Mangools sits between a lightweight inspector and a full data toolbar. Its extension covers on-page SEO, structured data, outbound links, PageSpeed checks and enhanced SERP research. It can also connect the current page or search result to Mangools tools for keyword, backlink and profile analysis.

The account boundary is the part worth understanding. Without a Mangools account, the extension still provides unlimited on-page checks, PageSpeed checks, context-menu integrations and advanced SERP tools. With an account, it adds richer domain and URL data, including DA, PA, CF, TF, keywords, backlinks and rank-tracking functions. Mangools offers a free account, though its limits are naturally lower than those of paid plans.

This makes Mangools attractive to users who want a single approachable interface that can grow into a broader suite. It is less compelling for someone whose only job is to inspect metadata, because Detailed or SEO Meta in 1 Click provides that information with less account and product overhead.

Choose Mangools if: you want a simple bridge from browser-level checks into keyword, SERP and backlink research rather than a standalone technical extension.

6. SEO Meta in 1 Click – best lightweight MozBar alternative for metadata

SEO Meta in 1 Click is deliberately narrower. It surfaces the title, description, canonical URL, meta robots directives, heading hierarchy, image alt coverage, internal links, Open Graph data, Twitter card data, robots.txt and sitemap information from a compact Chrome extension.

That is enough for editors, developers and site owners who mainly open MozBar to answer simple questions such as: Is the canonical correct? Is there more than one H1? Is the page noindexed? Are image alt attributes missing? It avoids pulling a full backlink or keyword product into a task that does not need one.

The trade-off is maintenance pace and depth. The Chrome Web Store currently shows its last update as August 2024. The extension still covers the basics well, but users who want active technical development, redirect tracing, or SERP research should choose another option.

Choose SEO Meta in 1 Click if: you want a quick, low-clutter Chrome inspector for metadata and page structure, not a replacement for Moz’s data products.

7. SEO Pro Extension – best free specialist for redirects and technical checks

SEO Pro Extension ranks seventh because it fills a technical gap left by many free MozBar alternatives. It shows titles, descriptions, canonicals, robots directives, and heading structure, and also adds Core Web Vitals field data, status codes, redirect chains, link and anchor-text analysis, nofollow highlighting, image alt checks, and schema inspection.

Its export options are unusually practical for a free extension. Headings, links, images, and page copy can be exported to CSV or copied out for further review. That makes it useful for technical QA and competitor-page teardown where the objective is to collect page evidence rather than see an authority score.

The limitation is scope. It does not provide its own backlink index, authority score, keyword-volume data or rich SERP overlay, and its current Chrome Web Store version is Chrome-focused. It is therefore a specialist replacement for MozBar’s inspection layer rather than the full MozBar experience.

Choose SEO Pro Extension if: redirects, indexability, Core Web Vitals, and exportable technical checks matter more than DA, backlinks or keyword data.

You may not need a MozBar replacement at all

The weakest setup is often the one with the most extensions. Installing Detailed, Ahrefs, SEOquake, Keywords Everywhere, and Mangools together can duplicate page checks, add multiple SERP widgets, and make it harder to remember which metric came from which database.

A better workflow gives each extension one clear job:

Workflow	Extension 1	Extension 2	Why it works
Fast page inspection plus authority research	Detailed	Ahrefs SEO Toolbar	Use Detailed for instant page checks, then enable Ahrefs metrics only when link or authority context is needed
SERP-heavy keyword research	SEOquake	Keywords Everywhere	SEOquake handles result-level comparison while Keywords Everywhere adds query demand and Moz-linked context
Editorial QA	SEO Meta in 1 Click	None	A second extension adds little if the job is simply checking metadata, headings, robots and images
Technical spot checks	SEO Pro Extension	None or Ahrefs on demand	SEO Pro covers redirects, canonicals, schema and Core Web Vitals without turning every SERP into a dashboard

This small-stack approach also makes browser problems easier to diagnose. If Google search results suddenly look broken or a page behaves differently, two focused extensions are simpler to disable and test than a toolbar collection with overlapping content scripts.

For a wider look at which SEO products practitioners keep in their working stack, our guide to SEO tools practitioners actually recommend covers comprehensive research, crawling and optimisation tools separately. This page focuses on browser extension replacements for MozBar.

Free extensions are cheap because page inspection and SEO data have different costs

There is a simple economic reason no free MozBar alternative dominates every category. Reading the HTML, headings, canonicals, schema and links on the current page can be done inside the browser. Maintaining a fresh backlink graph, keyword database, traffic model or authority score requires crawling, storage and repeated processing outside your browser.

That is why the strongest free inspectors tend to stop short of proprietary metrics, while the data-heavy extensions introduce accounts, credits, row limits, or paid plans. Treat those limits as part of the product, not an inconvenient footnote. If you only need a backlink metric twice a week, a free account tier may be enough. If an agency loads metrics across hundreds of SERPs every day, the usage model becomes a buying criterion.

Extension permissions deserve the same attention as the feature list

SEO extensions need access to page information to inspect titles, links, structured data and network behaviour. That access is not automatically suspicious, but the permission scope should make sense for the feature being delivered. Chrome’s extension permission guidance explains that host permissions allow an extension to interact with matching pages, inspect tab information, inject scripts, or monitor requests, depending on the APIs used.

Check the current store listing before installation because permissions can change between versions. Detailed states that it uses zero tracking. SEO Meta in 1 Click and SEO Pro currently declare that they do not collect data in their Chrome Web Store privacy sections. Keywords Everywhere says keyword queries are sent to its server when metrics are fetched but are not stored. Extensions that return proprietary backlink, traffic or keyword data necessarily have to communicate with a provider service at some point.

For client work, a sensible policy is to install only the extensions the team actually uses, restrict site access where the browser allows it, and review permissions after major updates. A browser stuffed with abandoned extensions creates more risk and more debugging work than a short, deliberate toolkit.

Common mistakes when replacing MozBar

• Treating DA, DR, PA, CF and TF as interchangeable. They come from different providers, link indexes and scoring systems. Compare like with like over time rather than converting one score into another.
• Choosing by the longest feature list. A metadata editor does not need a permanent SERP overlay, while a link prospector gains little from a minimalist title-tag viewer.
• Leaving every data overlay enabled. Persistent SERP metrics create clutter and can also consume account allowances on tools that meter data requests.
• Trusting an audit score more than the underlying issue. Extensions are good triage tools. They are not substitutes for crawling a site, checking rendered output or deciding whether a flagged item can affect search performance.
• Ignoring maintenance and browser support. A free extension that has not kept pace with changes in browser platforms can become a liability, even if its original feature list looks excellent.
• Using a toolbar as a crawler. Page-by-page inspection is ideal for spot checks. Site-wide canonicals, redirect patterns, orphan pages and large-scale indexability problems need a crawler or platform built for the job.

Which MozBar alternative should you choose?

Start with the function you would miss tomorrow, not the brand name you are replacing.

• Choose the Detailed SEO Extension if page inspection is your main task and you want a genuinely free, low-friction tool.
• Choose Ahrefs SEO Toolbar if authority, backlinks, redirects and SERP research need to live in the same workflow.
• Choose SEOquake if the SERP overlay and exportable result comparison are the main reasons you use MozBar.
• Choose Keywords Everywhere if you want Moz-linked authority information, plus keyword and traffic context, within Google.
• Choose Mangools if you prefer a simpler extension that connects directly into a broader keyword, SERP and backlink suite.
• Choose SEO Meta in 1 Click if your checks rarely go beyond metadata, headings, robots, canonicals and images.
• Choose SEO Pro Extension if redirect chains, Core Web Vitals, and technical exports matter more than authority scores.

For most people, Detailed is the best free MozBar alternative to install first. Add a second data layer only if you can name the metric or SERP task that Detailed cannot supply. That keeps the browser fast to work in, makes the data source obvious and avoids paying for a full SEO suite simply to recreate one toolbar feature.

Frequently asked questions

What is the best free alternative to MozBar?

Detailed SEO Extension is the best free MozBar alternative for page inspection because it covers headings, robots information, schema, hreflang, links, images, nofollow highlighting and useful exports without a paid plan. If you mainly use MozBar for authority or backlink data, Ahrefs SEO Toolbar or Keywords Everywhere is a closer match.

Which free MozBar alternative shows Domain Authority?

Keywords Everywhere currently includes Moz link metrics such as Domain Authority and backlink data in its free feature set. Mangools can also show DA and PA when connected to an account. Remember that Moz DA, Ahrefs DR, and Majestic metrics are different scoring systems and should not be compared as if they were the same.

Can I see Ahrefs DR without paying for Ahrefs?

Ahrefs’ current SEO Toolbar page says users can sign in for free to access Domain Rating and URL Rating for a site. The fuller metrics layer, including broader backlink, traffic, keyword, and SERP data, still requires paid access.

Is SEOquake still free in 2026?

Yes. SEOquake still offers a free browser extension with page audits, internal and external link analysis, SERP overlays, domain or URL comparisons and data export.

Is MozBar still worth using in 2026?

Yes, if you want Moz’s own DA and PA metrics, its SERP overlay and its page-inspection workflow. MozBar V5 was rebuilt in 2026, so switching away should be based on the metrics, browser workflow, or account model you prefer, rather than on the assumption that MozBar is no longer maintained.

Can one free extension completely replace MozBar?

Not perfectly. Free extensions can reproduce most page-inspection features, but proprietary authority, backlink, traffic and keyword data depend on external databases. A two-tool setup, such as Detailed plus Ahrefs or SEOquake plus Keywords Everywhere, is often a cleaner replacement than searching for a single extension that does everything.
