7 Screaming Frog Alternatives (Free and Paid)

September 30, 20267 min read

The best Screaming Frog alternatives are Sitebulb (the closest desktop equivalent, with better visual reports), LibreCrawl (free and open source), and Ahrefs Webmaster Tools (a free cloud site audit for sites you own). Which one fits depends on why you're leaving Screaming Frog: the 500-URL free limit, the price, the learning curve, or the need for a cloud tool. Below is how each alternative compares, with honest trade-offs.

Quick picks

  • Closest replacement: Sitebulb. Same desktop crawler model, with clearer prioritized "hints" and crawl maps.
  • Free with no URL cap: LibreCrawl (open source) or Ahrefs Webmaster Tools (free for verified sites).
  • Enterprise and cloud scheduling: Lumar (formerly Deepcrawl).
  • You actually want to find what looks broken to customers: a visual scanner like BugSense, not another SEO crawler.

The alternatives in detail

1

Sitebulb

Closest replacement
Sitebulb is the alternative most Screaming Frog users try first. It crawls the same way (a desktop app, with a cloud version for teams), but instead of handing you raw data tables it groups issues into prioritized "hints" that explain what's wrong and why it matters. The crawl maps and PDF reports are much easier to hand to a client. The trade-off: it's less flexible than Screaming Frog for custom extraction and very large crawls. There's a 14-day free trial with no card required (current pricing).
2

LibreCrawl

Free
LibreCrawl is a free, open-source (MIT-licensed) SEO crawler that runs on Mac, Windows, Linux, or Docker. It crawls pages, analyzes links, extracts SEO data, and exports results, with no subscription and no 500-URL cap. It's younger and less polished than the paid tools, and there's no vendor support, but for broken links, redirects, and missing tags on a budget it's the most direct free swap.
3

Ahrefs Webmaster Tools

Free
Ahrefs Webmaster Tools gives you Ahrefs' cloud Site Audit free for any website you can verify ownership of. It runs in the cloud on a schedule, so there's nothing to leave running on your laptop, and it flags broken links, redirect problems, and on-page issues. The catch: it only works on sites you own. It's no use for auditing a competitor or a prospect's site before a pitch.
4

Semrush Site Audit

If you already pay for Semrush, its Site Audit covers most of what Screaming Frog does for day-to-day SEO health checks, with a site health score and issue tracking over time. A free account can run a limited audit, and full-size audits need a paid plan. It's a good choice when you want audits, keyword research, and rank tracking in one tool. It's poor value if you only need a crawler.
5

Lumar (formerly Deepcrawl)

Lumar is an enterprise cloud crawler built for sites with hundreds of thousands or millions of URLs, with scheduled crawls, team workflows, and integrations into development pipelines. Pricing is on request. It's overkill for small sites, but it's the usual step up when a desktop crawler runs out of memory.
6

Google Search Console

Free
Not a crawler, but often the thing people actually need. Search Console's Pages report shows the URLs Google found broken (404s, server errors), redirected, or excluded, and why. For many small sites, checking it weekly catches most crawl problems without any extra tool.
7

BugSense (for a different kind of problem)

Worth saying plainly: BugSense is not an SEO crawler and won't audit meta tags or redirect chains. But many people searching for a Screaming Frog alternative are really asking "what's broken on my site?", and a crawler reads HTML without ever rendering the page. BugSense loads your pages in a real browser at mobile, tablet, and desktop sizes and finds broken images, layout failures, covered buttons, and JavaScript errors customers actually hit. Most sites benefit from a crawler and a visual scanner. See our detailed BugSense vs Screaming Frog comparison.

Is there a free version of Screaming Frog?

Yes. The free version of Screaming Frog SEO Spider crawls up to 500 URLs per crawl and covers the core audits (broken links, redirects, titles and meta descriptions, duplicate pages). For small sites under 500 pages, the free version is often all you need. The paid licence removes the limit and adds scheduling, JavaScript rendering, and integrations with Google Analytics and Search Console.

Sitebulb vs Screaming Frog: the key differences

Both are desktop crawlers that find the same core issues. The difference is presentation and workflow. Screaming Frog gives you raw, highly configurable data and assumes you know what to look for. It's the power tool. Sitebulb interprets the crawl for you, ranks issues by importance, and explains each one, which suits people who audit occasionally or report to clients. Screaming Frog is cheaper for a single user. Sitebulb is faster to act on.

How to choose

Leaving because of the 500-URL limit

Try LibreCrawl (free) or Ahrefs Webmaster Tools (free for your own sites) before paying for anything.

Leaving because it's hard to use

Sitebulb. Its prioritized hints are the biggest usability upgrade over Screaming Frog.

Need scheduled cloud crawls for a team

Semrush if you want a full SEO suite, Lumar if the site is very large.

Customers report things "look broken" but your SEO audit is clean

That's a rendering problem a crawler can't see. Run a visual scan across devices.
