What is a good free alternative to Screaming Frog?

It depends on what you need it for — a browser-based full-site audit tool covers on-page and technical checks with zero install for occasional use, while open-source crawlers like LibreCrawl suit anyone comfortable running their own tooling for larger, more frequent crawls.

Does Screaming Frog have a free version?

Yes — the free tier crawls up to 500 URLs, which fully covers many small sites. The limit only becomes a factor on larger sites or for agencies crawling many client sites regularly.

Is there a browser-based alternative to Screaming Frog?

Yes — a full-site audit tool run entirely from a URL bar covers the same category of on-page and technical checks (titles, headings, status codes, canonicals) without installing a desktop app or a Java runtime.

What does Screaming Frog do that a lighter tool can't?

Finding patterns that only show up across dozens or hundreds of pages at once — every page on one template missing the same tag, or a redirect loop several levels deep. A full-site crawler is the right tool for that; a lighter, single-page tool is better for checking one page right now.

Can I use Google Search Console instead of a crawler?

For your own site's indexing status specifically, yes — Search Console's coverage reports already show which pages are indexed, excluded, or flagged with errors, at zero cost. It doesn't crawl competitors or replace on-page checks a crawler runs directly against the HTML.

Screaming Frog Alternatives: Free & Browser-Based Options

What Screaming Frog actually does

Screaming Frog SEO Spider is a desktop crawler — you point it at a site, it follows every internal link like a search engine would, and reports back on titles, headings, status codes, redirects, canonical tags, and a long list of other on-page and technical details, page by page, across the entire site at once. It's genuinely good software and the free version handles up to 500 URLs, which covers plenty of small sites completely. Where people start looking for alternatives is past that limit, or when a full desktop install and a Java runtime feels like overkill for checking one site occasionally rather than crawling dozens of client sites every week.

What to actually compare before switching

Crawl limit — how many URLs a free tier actually covers before hitting a paywall or a hard cutoff.
Install versus browser-based — a desktop app needs installing (and, for Screaming Frog specifically, a Java runtime) versus a tool that runs entirely from a URL bar.
What gets checked — some alternatives focus narrowly on one thing (broken links only, say) rather than the full spread of titles, headings, status codes, and canonicals together.
Export and reporting — whether results come back as a usable report or just an on-screen list you have to manually transcribe.
JavaScript rendering — sites built on React, Vue, or similar need a crawler that actually executes JavaScript to see the real content, not just the raw server response.

CheckSEO's Full Site Audit runs the same category of checks — titles, headings, status codes, canonicals, and more — against a URL in one pass, right in your browser, no install and no signup.

Run a Full Site Audit

The realistic alternatives, by what they're actually good for

A browser-based full-site audit tool

For anyone who wants a snapshot of on-page and technical health without installing anything — titles, headings, alt text, canonical issues, and crawl problems in one pass, run entirely in the browser. The tradeoff versus Screaming Frog: less granular control over crawl depth and custom extraction, in exchange for zero setup.

Sitebulb

A genuine desktop competitor with a more visual, guided interface than Screaming Frog's dense data tables — a reasonable pick for teams that want the same depth of crawling but find Screaming Frog's UI intimidating. Still a paid product past its trial, and still a desktop install.

LibreCrawl and other open-source crawlers

Free, source-available crawlers exist specifically as a no-cost Screaming Frog alternative for people comfortable running their own tooling. The tradeoff is exactly what you'd expect from open-source infrastructure software — less polish, smaller community for troubleshooting, and features that lag behind a mature commercial product.

Google Search Console's own coverage reports

Not a crawler at all, but worth remembering: Search Console already tells you which of your own pages Google has indexed, excluded, or flagged errors on — for your own site specifically (not competitors), this sometimes answers the question a full third-party crawl was about to be used for anyway, at zero cost and with no setup.

Netpeak Spider and other niche desktop crawlers

Smaller, less widely known desktop crawlers exist with their own pricing and feature tradeoffs — worth a look if a specific gap (a particular export format, a specific extraction feature) isn't covered by the bigger names, but generally covering the same ground as Screaming Frog and Sitebulb rather than doing something meaningfully different.

Where a full-site crawl actually beats a single-page checker

It's worth being honest about what a browser-based, single-URL-at-a-time tool genuinely can't replace: finding a pattern that only shows up across dozens or hundreds of pages at once — every product page on one template missing the same tag, a specific redirect loop three levels deep in the site architecture, or a cluster of orphaned pages with no internal links pointing to them at all. A desktop crawler that walks the entire site graph is the right tool for that specific job. What a lighter tool is genuinely better at: checking one page right now, with no setup, when you already know or suspect where the problem is — most day-to-day SEO troubleshooting is exactly this second case far more often than the first.

A realistic way to combine both

For a small-to-mid-size site, a workable pattern is to run a full crawl (Screaming Frog's free tier, or any of the alternatives above) quarterly or after any major site change to catch the systemic, template-level issues, and use a lighter browser-based checker for everything in between — a one-off page check before publishing, confirming a specific fix landed, or a quick health check when something feels off. Neither tool replaces the other; they cover different frequencies of the same underlying work.

CheckSEO's Full Site Audit covers the on-page and technical checks most people reach for Screaming Frog to answer on a single page — no install, no Java runtime, and nothing to configure before you get a result.
