Summarize this article with AI
Looking for a Screaming Frog alternative usually means you've run into one of three walls. Maybe it's the free version's URL cap, maybe a laptop that can't get through a big crawl overnight, or maybe a license bill that grows each time someone joins the team. Some of those justify a switch. Others go away once you know what the paid SEO Spider already does.
This guide starts with that check, then compares free crawlers you may already have and hosted tools for teams by the problems they solve. It also covers running Screaming Frog on a cloud VM and includes a migration checklist. Every price and limit comes from the vendors' own pages (US prices, October 2026).
Which Screaming Frog alternative fits the problem you actually have?
For prioritized reports it's Sitebulb Pro; hosted collaboration points to Sitebulb Cloud, and monitoring alerts to Sitechecker. Can you verify the site? Then Ahrefs Free is a decent free check, and LibreCrawl is there if you'd rather run something open-source yourself. But first, figure out if the thing bugging you is the free Screaming Frog SEO Spider or the paid one. It's not the same conversation.
| What you need to change | Shortlist | Check first |
|---|---|---|
| Too much time explaining technical SEO findings | Sitebulb Pro | Test its Hints and PDF reports against an issue you already understand. |
| Overnight crawling without keeping your laptop awake | Sitebulb Cloud, or SEO Spider on a cloud VM | Paid SEO Spider already schedules crawls; decide who will manage the machine. |
| Browser access and change alerts for a team | Sitechecker | Confirm project coverage and the reports your team will use. |
| No separate subscription for technical SEO checks | Your existing Semrush, Ahrefs, or Moz plan | Check rendering, per-audit limits, and repeat-crawl allowances. |
| Free checks for sites you own | Ahrefs Free | Confirm ownership and monthly crawl credits. |
| A free, open-source Screaming Frog alternative | LibreCrawl | Test the setup, rendered output, and exports on your own machine. |
| Crawl findings alongside server logs | JetOctopus | Bring a real crawl-and-log question to the demo. |
Key takeaways: switching makes sense for a different interface, shared hosted projects, or less machine babysitting. If it's only scheduling, Search Console metrics or site-structure diagrams you're after, look at the license you already have.
Check what Screaming Frog already does before switching
With the free SEO Spider, 500 URLs is the ceiling. The free version stops there, and the paid license costs £199 ($279, €245) per year, per seat.1 Paying also adds configuration, saved crawls, JavaScript rendering, integrations, and scheduling.2
| Complaint | What the paid SEO Spider already supports | What to check |
|---|---|---|
| “I need an automated schedule.” | One-off or recurring scheduling, headless runs, exports, and email notifications | Open File > Scheduling and keep the machine on and awake. |
| “The site is too large.” | Database storage; capacity depends on allocated memory and storage | Check storage mode, SSD capacity, and memory allocation before switching tools. |
| “I need search performance beside the crawl.” | Search Console clicks, impressions, CTR, and position per URL | Connect the property and choose the relevant date range. |
| “I need Google's indexing details.” | URL Inspection API data, including index status, canonicals, and last crawl | Account for its allowance of up to 2,000 URLs per property per day. |
| “I need to show site structure.” | Force-directed diagrams, crawl trees, directory trees, and semantic content clusters | Try the relevant visualization before paying for another interface. |
| “I need automated change comparisons.” | Auto Compare Crawls for scheduled and command-line crawls | Review change notifications from successive runs in a project. |
Database storage is the default. Screaming Frog recommends a 1TB SSD and 16GB RAM setup, with 4GB allocated for crawls up to 2 million URLs.1 A laptop can run out of memory in the older memory storage mode, where (per Screaming Frog's FAQ) 8GB allocated to the SEO Spider generally covers about 200,000 URLs. Big crawls failing again and again? Look at the storage mode before you look at other tools.
A scheduled crawl can drop exports into local files or Google Sheets, email you, and append crawl-overview data so Data Studio can chart it over time. Auto Compare Crawls compares the last two crawls in a project.3 So if automating a report is the whole reason to buy something new, try a scheduled export first (machine awake).
Version 24 (2026) also includes the Screaming Frog SEO Spider MCP server for Claude and other AI assistants.3 Through it, an assistant can run the crawler and then analyze, export and manipulate the data. Check this route before switching solely for an assistant connection.
Free Screaming Frog alternatives and their real limits
Got a verified site? Ahrefs Free is the first stop, as long as the credit allowance stretches far enough for your crawl. LibreCrawl is for the crowd that would rather own the hosting (and the open-source code) than use a ready-made service. Rendering pages, saving results and repeating the checks are the bar any free Screaming Frog alternative has to clear.
| Free option | Allowance or restriction | Why consider it? |
|---|---|---|
| Ahrefs Free Site Audit | 5,000 crawl credits per verified project per month; unlimited verified websites | JavaScript execution and checks for 170+ SEO issues |
| Semrush Free Site Audit | Without the SEO Toolkit: 100 pages per month and per audit | Small-site auditing without a paid plan or credit card |
| Bing Webmaster Tools Site Scan | Free technical SEO audit | Broken links, duplicate tags, and missing metadata |
| SEO PowerSuite WebSite Auditor Free | 500 URLs, one project, no saving | A Windows, macOS, or Linux desktop option |
| LibreCrawl | Free MIT-licensed software; run locally or self-host | Playwright JavaScript rendering and CSV, XLSX, JSON, or XML exports |
| Xenu's Link Sleuth | Free; Windows only; current version dates to 2010 | A broken-link checker, not a modern site audit |
Ahrefs Free uses crawl credits for HTML pages that return 200.4 Don't assume those credits count the same thing as another tool's page limit. And since the free Site Audit only works on sites you've verified, a prospect's site is off limits unless they let you verify it.
LibreCrawl is a Python Flask web app with separate sessions for concurrent users.5 Run it on your own machine or host it with Docker; either way, settings are stored in browser localStorage. Write your settings down somewhere, and plan time for looking after the install and the machine.
LibreCrawl's crawler settings go up to 5 million URLs.5 That's a lot, so time a representative section and check the exports before you plan a full-site run. Scheduled reporting or Search Console integration on your must-have list? Test those specifically before an open-source replacement gets the job.
Sitebulb's 14-day trial is another way to test a replacement, but it isn't an ongoing free plan.6 We compare whole free suites in the free Ahrefs alternatives and free Semrush alternatives guides.
Prices and limits side by side (US, October 2026)
Look at how each one bills, and what it counts, before you line up prices. A per-audit limit, a monthly credit pool and a weekly allowance all measure something different. Monitoring changes means reruns, so check what's left for those and not just the initial crawl.
| Product and plan | USD price | Crawl allowance or purchase check |
|---|---|---|
| Screaming Frog SEO Spider paid | $279/year per user | No fixed paid URL cap; allocated memory and storage determine capacity |
| Sitebulb Lite | $18/month or $180/year | 10,000 URLs per audit; one user; no Scheduled Audits |
| Sitebulb Pro | $42/month or $425/year | 500,000 URLs per audit by default; can be raised to 2 million, subject to machine capacity |
| Sitebulb Cloud | From $125/month or $1,500/year | Up to 10 million URLs per audit; two or more users; no project limits |
| Sitechecker Basic | $99/month or $83/month billed yearly | Unlimited users and recrawls; confirm the required project coverage |
| Ahrefs Lite | $129/month | 100,000 crawl credits per month; maximum 25,000 pages per project |
| Semrush SEO | $139/month or $117.33/month billed yearly | Includes Site Audit; confirm which SEO Toolkit tier and rendering allowance your purchase includes |
| Moz Pro Starter | $49/month | One campaign; 5,000 pages crawled per week; no On-Demand Crawls |
| Moz Pro Standard | $99/month or $79/month billed yearly | Three campaigns; 100,000 pages per week; five On-Demand Crawls |
| Netpeak Spider | From $20/month | Confirm the plan's crawl and reporting details before choosing it. |
| SEO PowerSuite Professional | $349/year for the bundle | WebSite Auditor can crawl entire sites; Windows, macOS, and Linux |
| JetOctopus | Request pricing | Monthly crawled-URL tiers: 500,000, 2 million, 5 million, or custom; unlimited projects and seats |
| Lumar, Botify, Oncrawl | Request pricing or a demo | Ask for a quote against your actual crawl and team requirements. |
Compare users as well as URLs
Screaming Frog licenses are assigned per user, rather than shared across a team. Each teammate who needs access needs their own license.2 A single user can use their license on multiple devices.1
| Number of SEO Spider licenses | Annual USD price per license |
|---|---|
| One to four | $279 |
| Five to nine | $265 |
| 10 to 19 | $249 |
| 20 or more | $235 |
Sitebulb Pro sells extra users as a monthly add-on.6 Sitechecker includes unlimited users on all plans, while JetOctopus includes unlimited seats and projects. For teams, compare costs based on the seats you need, then check the crawl allowance separately.
Paid Screaming Frog alternatives by workflow
Sitebulb: prioritized Hints and a choice of setup
Sitebulb Pro includes 300+ Hints with issue prioritization, audit comparisons, customized PDF reports, and Scheduled Audits.6 Every Sitebulb plan, even the cheapest, comes with JavaScript crawling, Google Analytics, Search Console and Google Sheets integrations, Crawl Maps and MCP access. Lite is missing a few things, though: hreflang checks, structured data checks and scheduling. The entry price doesn't buy the full feature set.
Here's a good trial test: hand a teammate a report and see if they can turn it into a fix ticket. That tells you how clearly Sitebulb explains its prioritized Hints. Site-structure diagrams exist in both Sitebulb and Screaming Frog. Pick the diagram that answers the structure question you're actually asking.
Sitebulb Cloud lives in the browser, runs recurring crawls on its own and still ties into the desktop app natively. The desktop trial lasts 14 days, is equivalent to Pro, and requires no credit card.6
Sitechecker: monitoring and shared reports
Sitechecker runs in the browser as a monitoring platform and folds in Search Console and Google Analytics 4 insights. Its Site Monitoring tracks content changes, and a page going broken or non-indexable triggers an email or Slack alert. It also offers white-label reporting for agencies.7
Sitechecker also includes a rank tracker and AI search visibility tracking on all plans.8 Work out the alert flow before you pay. Who gets the alert, who checks the page, and what does the PDF or spreadsheet need to show? And ask them to show you a report that actually names the affected pages and what changed.
Semrush, Ahrefs and Moz: start with the subscription you have
Semrush Site Audit covers 140+ on-page and technical SEO checks, including duplicate content and hreflang.9 Recrawls can run on a daily or weekly schedule. JavaScript rendering, though, only comes with the Guru or Business SEO Toolkit tiers. Check which toolkit your account includes separately from the advertised SEO plan price.
| Semrush SEO Toolkit tier | Pages per month | Pages per audit | JavaScript rendering |
|---|---|---|---|
| Pro | 100,000 | 20,000 | No |
| Guru | 300,000 | 20,000 | Yes |
| Business | 1,000,000 | 100,000 | Yes |
Ahrefs Site Audit checks 170+ issues and executes JavaScript.10 Lite includes 100,000 crawl credits a month and caps each project at 25,000 pages, so a bigger site needs a higher plan or a narrower crawl.11 Before you buy anything else, push your biggest section through the subscription you already have.
Moz Pro users should look at how their plan divides weekly campaign crawls and On-Demand Crawls. That split decides whether it can handle one-off audits.
Screaming Frog versus Semrush? Test the jobs Screaming Frog does for you right now. Throw in technical SEO issues you already know about (duplicate content, broken links) and ask for the reports you'd actually hand off. Look at the rendered output, title tags and meta tags as well. A lower error count doesn't prove the site is healthier. For a broader suite decision, see our guide to Moz alternatives by budget and workflow.
Lumar and JetOctopus: enterprise QA or crawl-plus-log analysis
Lumar, formerly DeepCrawl, is an enterprise web platform with 350+ reports and Protect for automated QA tests. Lumar says its 450 URLs per second figure applies to non-rendered pages; its stated speed for rendered pages is up to 350 URLs per second.12 Request a demo of the QA tests your team will run, rather than using the speed figure to predict completion time.
JetOctopus combines a cloud crawler with a log analyzer, Search Console and Google Analytics 4 integrations, and MCP integration. Its plans meter crawled URLs per month and include unlimited projects and seats.13 Start here if the requirement is crawl-plus-log analysis, and use our log file analysis SEO workflow to prepare the questions you want the demo to answer.
Click Botify's pricing link and you land on a demo request. Oncrawl's site sends you to a demo as well. Take the same rendered sample and the same team and reporting requirements into each of those calls. Then you're comparing something concrete instead of sales presentations.
Keeping Screaming Frog, but on a cloud VM
Is the laptop the real problem? If you'd like to keep your configurations, rent a cloud machine and run Screaming Frog there. Screaming Frog supports local computers, dedicated servers, and cloud VMs on Windows, macOS, or Linux.1 The machine and its updates are still yours to manage. And every person who uses the instance needs their own license.
Screaming Frog's Google Cloud tutorial reports crawling 3.1 million URLs in database storage mode in about two days.14 That run used eight vCPUs, 32GB of memory and a 200GB SSD, and the Google Cloud bill came to less than £20. Remember it's the vendor's own example. Your site's rendering and crawl needs could cost something else entirely.
It only works if somebody owns uptime, storage, exports and the usage bill. For a one-off crawl, terminate the VM afterward; keeping it running for scheduled crawls adds cost.14 Maybe the team really wants a hosted dashboard in the browser. Then shortlist a hosted platform.
Pair the crawl snapshot with Search Console trends
Crawled URLs in paid Screaming Frog already come with Search Console clicks, impressions, CTR and position attached. The range is the last 30 days unless you change it. Use that snapshot to check whether a flagged page gets search clicks before writing the ticket.
Trends over time are where SEO Heatmap comes in: each page's clicks by month for 16 months, or by week for 16 weeks. Pages that are gaining or losing clicks surface through its growing and falling filters and the AI insights. Queries get their own Keywords tab, with clicks, impressions and average position for each.
Take a page the crawl flagged and find the point where its clicks started to fall. Does that line up with the crawl finding? Put those dates in the ticket. A match is a clue, though, not proof the technical issue caused the drop. Once the fix ships, look at the trend again. Google Search Central lists seasonality and changing search interests among the causes to investigate when traffic drops.15
SEO Heatmap is free for one Search Console property and connects through Google sign-in. It also supports Claude and ChatGPT through MCP. To choose how an assistant accesses search-performance data, see our Google Search Console MCP guide.
Before you switch: save your work and test a real crawl
Save readable exports before your Screaming Frog license expires. After expiry, the SEO Spider returns to the restricted free version, and opening saved crawls requires a license.1 Keep the database or .seospider file too, not just the reports.
- Baseline crawl saved, configurations and custom extraction rules written down, all before expiry.
- List scheduled tasks, API connections, output destinations, and email notifications to rebuild.
- Confirm someone can authorize the replacement's Search Console and Analytics connections.
- Does the subscription cover every person who'll review results?
- Ask for the white-label report your clients would see, and look at it before choosing a plan.
- Crawl a representative section with identical rendering and scope settings, and chase down any differences before the old setup goes.
One pilot record should hold both the buying decision and the migration notes. Your test set needs a page with a known issue, another that needs rendering, and a clean page. Misses matter as much as finds, and this is how you'll spot them.

Frequently asked questions
Is there a free version of Screaming Frog?
Yes. The SEO Spider has a free version, and it stops at 500 URLs. You won't get saving, configuration, JavaScript rendering, integrations or scheduling on it. If your audit fits under that URL limit, the free version is fine to start.
What is the best free Screaming Frog alternative for my crawl?
Ahrefs Free is the easy pick for a site you can verify, and LibreCrawl makes sense if you want open source you control. You get 5,000 crawl credits per verified project each month on Ahrefs Free, and it executes JavaScript. LibreCrawl has Playwright rendering and several export formats, but the installation and the machine are on you. Test your required output on a representative section before choosing.
Should I use Semrush instead of Screaming Frog?
Worth a try if you already pay for Semrush and its Site Audit allowances cover your audit. Recrawls run daily or weekly. For JavaScript rendering, though, you need a Guru or Business SEO Toolkit tier. Give both tools a problem you already know about, such as duplicate content, and compare the reports before you drop Screaming Frog.
How is Sitebulb different from Screaming Frog?
Sitebulb Pro leans on prioritized Hints and customized PDF reports. Sitebulb Cloud adds browser access and recurring crawls. Site-structure visualizations? Both tools have them. The 14-day desktop trial is the place to find out if a teammate can turn a Sitebulb finding into a fix ticket.
Why does my Screaming Frog crawl fail overnight?
The computer going to sleep mid-crawl is enough to kill it. Scheduling works on the paid version, one-off or recurring, but only while the computer is on and awake. Test a scheduled crawl and export under exactly those conditions. If the laptop can't stay awake, a cloud VM you run or a hosted platform solves it.
Does a failed large crawl mean I need a replacement?
No, check storage mode, SSD capacity, and memory allocation before switching. There's no fixed URL cap on the paid version. How far it gets depends on the memory and storage you give it. By default it uses database storage. Screaming Frog says 4GB allocated is enough for up to 2 million URLs, provided you're on an SSD. That's guidance for setup. Whether a crawl finishes on your machine is something you have to test.
What should I save before my Screaming Frog license expires?
Before it expires, export readable reports and keep the crawl file, configurations and custom extraction rules. Scheduled tasks, API connections and export destinations all need rebuilding later, so write them down. After expiry it drops back to the restricted free version, and saved crawls won't open without a license.
How does SEO Heatmap complement a crawl?
Screaming Frog attaches a snapshot of search performance to each crawl. SEO Heatmap adds the page-click trend behind it. That snapshot covers 30 days by default (adjustable). SEO Heatmap, by contrast, shows 16 months of monthly clicks or 16 weeks of weekly ones. Use it to see when a flagged page started slipping, then check again once the fix is live. Just don't assume the issue caused the drop.
Picking a crawl tool gets simpler once you know which pages are worth the attention. Connect a Search Console property to SEO Heatmap and the page-click trends will tell you which findings to fix before the rest. It's free for one Search Console property.
