Free Screaming Frog Alternative: The 7 Best Free Audit Tools in 2026
Paul VengeonsCo-Founder & SEO ConsultantIn short
Under 500 URLs, Screaming Frog itself is free. Above that, Ahrefs Webmaster Tools audits your verified sites for free (5,000 crawl credits per month per project) and Bing Site Scan covers up to 10,000 pages a month. Search Console shows what Google really indexes, PageSpeed Insights covers speed.
A free crawl lists hundreds of issues and fixes none of them. ChatSEO finds the pages losing traffic in your Search Console and fixes them.

Answer 5 questions to find your ideal tool
π¬ How I picked these free Screaming Frog alternatives
I only kept tools that audit a site for $0, with no card and no time limit. ChatSEO is the one exception: it is a free trial, and I flag it because I co-founded it.
Every free limit and price below was checked on the vendors' official pages on October 9, 2026. I scored each tool on four things: how free it really is, how many pages it can audit for free, the depth of its technical checks, and how clearly it tells you what to fix first.
My take after auditing client sites for years: most people looking for a free Screaming Frog do not need a desktop crawler at all. If your site has under 500 URLs, Screaming Frog itself is free. Above that, the free cloud audits from Ahrefs and Bing go further than most people expect.
π Free Screaming Frog alternatives compared
| Tool | What is free | Free audit size | Type | Best for |
|---|---|---|---|---|
| Screaming Frog (free version) | Full crawler, no time limit | 500 URLs per crawl | Desktop crawler | Sites under 500 URLs |
| Ahrefs Webmaster Tools | Site Audit, 170+ checks | 5,000 crawl credits/month per project | Cloud crawler | Sites you own |
| Bing Webmaster Tools Site Scan | On-demand technical scan | Up to 10,000 pages/month | Cloud crawler | Larger sites for $0 |
| Google Search Console | Indexing, Core Web Vitals | Your whole site, from Google's data | Google reports | What Google actually sees |
| Seobility (free plan) | 1 project, limited audit | 100 pages per crawl | Cloud crawler | Small sites, beginners |
| PageSpeed Insights | Lighthouse + field data | One URL at a time | Page tester | Speed and Core Web Vitals |
| ChatSEO | 5 free prompts, no card | URLs you ask about | AI agent on Search Console | Deciding what to fix first |
π The 7 best free Screaming Frog alternatives
1. Screaming Frog free version: the best choice under 500 URLs
The free Screaming Frog SEO Spider is the first alternative to try, because it is the same tool with one limit: 500 URLs per crawl. Broken links, redirects, duplicate titles, meta data, canonicals and XML sitemap generation all work in the free version.
If your site stays under 500 URLs, you never need to pay. Above that, the licence costs β¬245 per year per user, and that is when the free cloud tools below become interesting.
2. Ahrefs Webmaster Tools: the best free cloud audit
Ahrefs Webmaster Tools, now sold as Ahrefs Free, is the strongest free alternative for sites you own. Its Site Audit runs 170+ technical and on-page checks in the cloud, with 5,000 crawl credits per month per project.
Credits are only spent on HTML pages returning a 200, so redirects and broken links do not eat your quota. The limit is ownership: you must verify each site, so it does not work on prospects or competitors. Our free Ahrefs alternative guide covers the rest of the Ahrefs free stack.
3. Bing Webmaster Tools Site Scan: the biggest free crawl
Bing's Site Scan is the free audit with the highest page allowance: up to 10,000 pages a month. You launch a scan from Bing Webmaster Tools and get errors and warnings on titles, meta descriptions, broken links, redirects and blocked pages.
Most of what it flags hurts you on Google too, so do not dismiss it as a Bing-only tool. Sign-in is quick if your site is already in Google Search Console, because Bing can import your verified sites from it.
4. Google Search Console: the free source of truth for indexing
Google Search Console does not crawl like Screaming Frog, but it tells you what Google actually did with your pages, which no crawler can. The Pages report lists every URL excluded from the index and why: noindex, canonical chosen by Google, crawled but not indexed, redirect, 404.
Use it to check that a crawler's findings actually matter. A missing meta description on a page Google never indexes is noise; a canonical issue on your best category page is urgent.
5. Seobility free plan: a small cloud audit for beginners
Seobility's free Basic plan is a free-forever cloud audit, limited to 1 project and 100 pages per crawl. It also tracks 10 keywords and gives 5 daily tool credits, with no card required.
100 pages is less than Screaming Frog's free 500, so it only wins if you prefer a guided web interface to a desktop app. The first paid plan costs β¬59.90/month for 25,000 pages per crawl.
6. PageSpeed Insights: the free speed and Core Web Vitals check
PageSpeed Insights is Google's free page tester, and it covers the performance side Screaming Frog only reaches through an API key. Enter a URL and you get real-user Core Web Vitals (LCP, INP, CLS) plus a Lighthouse audit with what to fix.
It tests one URL at a time, so test one template per page type, not every page. A slow product template slows every product page built on it.

ChatSEO: best for deciding which technical fix comes first
ChatSEO is the tool I co-founded, and it is a free trial of 5 prompts with no card, not a free crawler. It connects to Google Search Console and answers the question a crawl export leaves open: which technical problems are costing traffic right now.
Ask it about a URL and it checks indexation, noindex tags, canonicals, robots.txt blocks and sitemap membership, then writes the JSON-LD your page is missing. After the trial, plans start at β¬29/month, or β¬23.20/month billed annually. Do not pick it to find every broken link on a 50,000-page site: that is a crawler's job.

πΈ What free crawlers leave you with
A free crawl gives you a list of issues, often hundreds, with no idea which ones cost traffic. A 404 on a page nobody visits and a canonical error on your top landing page land in the same spreadsheet, with the same color.
Sorting that list by impact is the real work, and it is the part no free tool does. That is where you either spend an afternoon cross-checking Search Console, or let an agent do it.

βοΈ Which free Screaming Frog alternative should you choose?
Pick from the size of your site and whether you own it.
- β Your site has under 500 URLs β keep the free Screaming Frog
- β You own the site and it is bigger β Ahrefs Webmaster Tools
- β You need the largest free crawl β Bing Webmaster Tools Site Scan
- β You want to know what Google actually indexes β Google Search Console
- β You care about speed and Core Web Vitals β PageSpeed Insights
- β You want the fixes ranked by traffic impact β ChatSEO trial
Never fix a crawl report top to bottom. Check each issue against Search Console first: an error on a page with no impressions can wait, one on a page that brings traffic cannot.
β Frequently asked questions
What is the best free alternative to Screaming Frog?
For sites you own, Ahrefs Webmaster Tools is the best free alternative: 170+ checks and 5,000 crawl credits per month per project. For the largest free crawl, Bing Webmaster Tools Site Scan goes up to 10,000 pages a month.
Is Screaming Frog free?
Yes, up to 500 URLs per crawl, with no time limit. The paid licence removes that cap and costs β¬245 per user per year.
Is there a free online alternative to Screaming Frog?
Yes: Ahrefs Webmaster Tools, Bing Site Scan and Seobility's free plan all crawl in the cloud, with nothing to install. All three need you to add or verify the site first.
Can Google Search Console replace Screaming Frog?
Not entirely: it reports what Google indexed and why, but it does not crawl your links like Screaming Frog. Use both: the crawler finds issues, Search Console tells you which ones matter.
Is ChatSEO free?
No, ChatSEO is a free trial of 5 prompts with no card, then from β¬29/month or β¬23.20/month billed annually. It is the option for ranking technical fixes by their impact on traffic.
π Final verdict
For a $0 technical audit, use the free Screaming Frog under 500 URLs, then Ahrefs Webmaster Tools or Bing Site Scan for bigger sites, with Search Console to confirm what matters. That stack covers most audits a freelancer or small business ever runs.
Who should just buy the Screaming Frog licence: agencies auditing sites they do not own, every week, at 10,000+ URLs. β¬245 a year is cheap for that job. When the problem is no longer finding issues but choosing which to fix first, the ChatSEO trial is the shortcut.
