JetOctopus vs Screaming Frog SEO Spider in 2026: cloud log intelligence vs the £199 desktop standard
One is a modular cloud platform priced by crawl and log volume, built for sites where crawl budget is a live problem. The other is a desktop crawler that has run on local machines since 2010 and still undercuts almost everything else in the category on price.
JetOctopus
Screaming Frog SEO Spider- Screaming Frog costs £199 per year for a single license with unlimited URLs. JetOctopus starts at 293 EUR per month for its base 500K-page plan, a roughly 15x to 20x difference in annual cost at the entry tier.
- Both tools include server log analysis, but JetOctopus tracks more than 40 bots including GPTBot, ClaudeBot, and PerplexityBot, while Screaming Frog's log analysis is described around mapping Googlebot crawl frequency specifically.
- Screaming Frog runs as a desktop app, so crawl speed depends on local machine specs and there are no scheduled cloud crawls without extra tooling. JetOctopus crawls from the cloud at up to 250 pages per second with zero load on the target server.
- JetOctopus has no user or project limits on any plan. Screaming Frog licenses are sold per machine, with volume discounts starting at 5 licenses (£189 each) down to £169 each at 20 or more.
- Screaming Frog supports custom data extraction via XPath, CSS selectors, and regex, plus an API for building custom reporting pipelines. JetOctopus does not document an equivalent custom extraction feature.
- JetOctopus includes 16+ months of Google Search Console history via bulk API and a GA4 integration. Screaming Frog connects to Google Analytics, Search Console, and PageSpeed Insights but does not extend GSC data retention beyond what Google provides.
- Screaming Frog offers a free version capped at 500 URLs to evaluate before buying. JetOctopus has no self-serve free trial; access requires direct contact or purchase.
JetOctopus and Screaming Frog SEO Spider both crawl sites and both analyze server logs, which makes them look more similar on paper than they feel in practice. Screaming Frog runs locally, caps nothing on the paid license, includes log analysis at no extra cost, and costs £199 a year total. JetOctopus runs in the cloud, prices by crawl and log volume with EUR-denominated add-ons, and starts at 293 EUR a month for its base plan, before add-ons. The real difference is not features so much as where the diagnostic work happens and who is paying for scale: JetOctopus's cloud crawler runs at up to 250 pages per second regardless of your hardware, while Screaming Frog's crawl speed depends on the machine it's installed on. For a freelancer auditing a handful of client sites, Screaming Frog's flat annual license is close to unbeatable value. For an enterprise team drowning in millions of URLs and unclear AI bot access, JetOctopus's cloud-native, no-seat-limit model earns its much higher price.
The tools at a glance
JetOctopus
SEO crawler and log analyzer for large sites that combines crawl data, server logs, GSC, and GA4 into one platform with no seat or project limits
JetOctopus is built for the scale at which a desktop crawler starts to strain: sites with millions of URLs, where crawl budget waste and AI bot access are ongoing operational concerns rather than a once-a-quarter audit question. The log analyzer ingests server logs directly and tracks more than 40 bots, including GPTBot, ClaudeBot, and PerplexityBot, so a technical SEO team can see exactly which pages each type of bot actually visits and how often, not just what a simulated crawl predicts.
The cloud architecture means crawl performance does not depend on the machine running it. The JS crawler processes up to 250 pages per second with no load placed on the target server, and 16+ months of GSC history is pulled via bulk API alongside GA4 data. An AI internal linker rounds out the platform, using crawl data to recommend link structure changes that JetOctopus says can improve crawl efficiency by up to 30%.
The cost of that scale is real. Pricing is EUR-based and modular, starting at 293 EUR per month for the base 500K plan with crawl, log, and GSC add-ons priced separately, and there is no free trial. Unlimited users and unlimited projects on every tier make the model genuinely cost-effective for agencies with many large clients, but a small site with a handful of pages gets none of the benefit of that pricing structure.

Screaming Frog SEO Spider
The industry-standard desktop crawler for technical SEO audits.
Screaming Frog has been the default technical SEO crawler since 2010, and the paid license still costs less per year than a single month of most enterprise platforms. It runs locally on Windows, macOS, or Linux, which means the crawl data never leaves your machine and there is no per-seat SaaS pricing to negotiate. The free version caps crawls at 500 URLs; £199 a year removes that limit entirely with no cap on site size.
What earns Screaming Frog its reputation is depth at that price: server log analysis included in the standard license (most competitors charge separately or skip it entirely), JavaScript rendering via Chromium, structured data and hreflang validation, and custom extraction via XPath, CSS selectors, or regex for pulling any data point out of page source. Combined with the API, that extraction capability turns the Spider into a flexible data pipeline rather than a fixed report generator.
The trade-off is entirely architectural: because it is a desktop app, crawl speed depends on the specs of the machine running it, and there are no collaborative dashboards or scheduled cloud crawls without bolting on separate tooling. For agencies running audits across dozens of sites or in-house teams with hundreds of thousands of URLs, that can mean a slower, more manual workflow than a cloud-native platform offers, even if the raw diagnostic output is just as deep.

Which should you choose?
Screaming Frog SEO SpiderJetOctopusJetOctopusScreaming Frog SEO SpiderJetOctopusScreaming Frog SEO SpiderJetOctopusThe honest framing is that these tools serve different budgets and different scales more than they serve genuinely different use cases. Screaming Frog's £199 a year buys nearly everything a technical SEO needs for sites up to a few hundred thousand pages, including log analysis most competitors charge extra for. JetOctopus starts to justify its much higher, EUR-modular pricing once a site is large enough that cloud-scale crawling, no-seat-limit collaboration, and AI-bot-specific log tracking stop being nice-to-haves and start being the actual job.
Bottom line
If your largest client site is under a few hundred thousand pages and you are comfortable running crawls locally, buy the Screaming Frog license, at £199 a year it will pay for itself on the first engagement and there is little reason to pay JetOctopus's enterprise pricing for capability you will not use. Move to JetOctopus once crawl budget on a genuinely large site becomes a recurring diagnostic problem, or once distinguishing GPTBot and ClaudeBot behavior from Googlebot specifically becomes part of the job, at which point the 293 EUR per month baseline buys real cloud-scale visibility that a desktop app cannot match.
Frequently asked questions
Is JetOctopus worth it over Screaming Frog for a small agency with a few clients?
Probably not for a small agency with modest-sized client sites. Screaming Frog's £199 per year single license covers unlimited URLs and includes log analysis at no extra cost, which is close to unbeatable value for audits under a few hundred thousand pages. JetOctopus's 293 EUR per month baseline only pays off once crawl volume, log line volume, or the number of large clients pushes past what a desktop crawler can comfortably handle.
Does Screaming Frog track AI bots like GPTBot the way JetOctopus does?
Not to the same degree. Screaming Frog's server log analysis is built around mapping Googlebot crawl frequency against site structure, without a documented feature for tracking AI-specific bots individually. JetOctopus tracks more than 40 bots by name, including GPTBot, ClaudeBot, and PerplexityBot, and has a dedicated AI Search Visibility module comparing AI crawler behavior against Googlebot.
Can Screaming Frog run scheduled crawls in the cloud like JetOctopus?
No, Screaming Frog is a desktop application, so crawls run locally on the machine it is installed on and depend on that machine's resources. There are no native scheduled cloud crawls or collaborative dashboards. JetOctopus runs entirely in the cloud and crawls at up to 250 pages per second regardless of your own hardware.
Why is JetOctopus so much more expensive than Screaming Frog?
The two tools are built for different scales. Screaming Frog is a flat-fee desktop license priced for individual practitioners and agencies running periodic audits, at £199 per year with unlimited URLs. JetOctopus is a cloud platform priced by crawl and log volume with unlimited users and projects included, aimed at enterprise sites and agencies where crawl budget and AI bot access are ongoing operational concerns rather than a one-off audit.
Does Screaming Frog have an API like JetOctopus?
Screaming Frog supports custom data extraction via XPath, CSS selectors, and regex, and this pairs with an API for building custom reporting pipelines from crawl data. JetOctopus's own tool data does not document an equivalent public API; its integrations are focused on pulling data in from Google Search Console and Ahrefs rather than exposing crawl data out.
Which tool is better for auditing a site with millions of URLs?
JetOctopus is the better fit at that scale. Its cloud crawler runs at up to 250 pages per second independent of local hardware, and unlimited crawl volume is available through add-on modules rather than being capped by what a desktop machine can process. Screaming Frog can technically crawl unlimited URLs on the paid license, but crawl speed and memory usage become dependent on the local machine, which can turn multi-million-URL sites into a slow, resource-heavy process.
