These tools have different discovery inputs and coverage, so their results are not interchangeable.
Which kind of broken-link check do you need?
Before choosing a tool, decide what you want it to discover. A check of one URL, a crawl of your own site, and a search-engine report each answer a different question.

| Method | Discovery input | Best suited to | Important boundary |
|---|---|---|---|
| Browser-based checker | A URL or domain entered into a public tool | A quick inspection of a page or site | Coverage depends on what the service scans; it is not proof that every URL or resource was checked. |
| Verified-site audit | A website whose ownership you verify with the service | Owners auditing their own site, including recurring checks | Access is conditioned on site verification and is not the same as an unrestricted third-party crawl. |
| Desktop crawler | A seed URL crawled by software on your computer | Auditing a site you control and examining crawl results | Crawl limits and advanced features depend on the software’s licensing terms. |
| Google Search Console | URLs Google has encountered | Reviewing Google-reported crawl, fetch, and indexing issues | It is not a complete audit of outbound links across a site. |
Browser-based checking: Ahrefs Broken Link Checker
Ahrefs describes its public Broken Link Checker as a way to check broken inbound and outbound links. Its listed views include dead pages with backlinks and internal links pointing to broken pages. The product page also describes a browser extension that highlights links and checks redirects or 404 responses, with extensions for Firefox and Safari.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For ongoing monitoring, Ahrefs says the public tool can schedule discovery daily, weekly, or monthly, compare crawls, and export reports. These are features described by Ahrefs, not independently measured findings about detection accuracy or speed. Choose this route when convenience and a quick starting point matter more than configuring a desktop crawl.

Auditing a site you own: Ahrefs Webmaster Tools
Ahrefs Webmaster Tools gives verified website owners free access to Site Audit, according to Ahrefs. The company lists broken-link data for internal and external links among its capabilities. Verification is required, so this is a practical option for checking a site you control—not a substitute for a public checker when you need to inspect an unrelated site.
Desktop crawling: Screaming Frog SEO Spider
Screaming Frog SEO Spider is a desktop crawler whose feature list includes finding broken links, errors, and redirects. Screaming Frog’s pricing page states that the free version is limited to 500 URLs; a license is required to crawl more than 500 URLs and access advanced features. Confirm the current limit and licensing terms on the vendor’s page before planning a large crawl or purchase.
A crawler is useful when you want to start from a site URL and examine the links it discovers. Its output still reflects the crawl’s scope and configuration: do not assume it has checked every possible URL, asset, or page variant.

What Google Search Console can—and cannot—tell you
Google Search Console reports issues involving URLs Google has encountered, including crawl, fetch, and indexing problems. A 2026 guide to finding broken links distinguishes those reports from a full outbound-link audit: Search Console does not show every broken link a site owner might want to find on other websites. Use it as a view of Google’s experience with your pages, not as your only link-checking method. The guide also notes that the online W3C checker has recursive-check limits and paces requests to reduce load; those details are reported by the guide, not established here as an independent comparison.
How to choose and act on results
For one page or a quick check
Start with a browser-based checker when you have a URL and want a low-setup inspection. If you need recurring reports, check whether the service offers scheduling and crawl comparisons, and review exactly what the report says it checked.
For a site you control
Use a verified-site audit when you want hosted Site Audit access tied to your ownership, or a desktop crawler when you want a local crawl workflow. For a small crawl, Screaming Frog’s free 500-URL limit may be enough under its current stated terms; larger crawls require a license.
Rank #4
For Google-specific problems
Use Search Console to investigate URLs Google encountered and its reported crawl or indexing problems. Pair it with a site crawl or link checker if the goal is to find outbound links that lead away from your site to dead destinations.
Before changing a link
A reported error is a reason to inspect a destination, not automatic proof that a link should be removed. Open the target and check its response, any redirect, and the page context. Depending on what you find, update the link, point it to a suitable replacement, restore the intended page, or remove it if it is no longer useful. A checker identifies candidates; it cannot make that editorial decision for you.

The descriptions above reflect vendor feature and limit statements and a 2026 secondary guide, accessed October 4, 2026. They are not the result of a controlled benchmark. No comparative detection-rate, speed, or accuracy test is established here, so there is no defensible universal winner: match the tool to the discovery source and coverage you actually need.
