Oncrawl vs Screaming Frog SEO Spider in 2026: enterprise cloud platform vs £199/year desktop crawler
Both do server log analysis, which makes this a closer fight than most enterprise-vs-desktop matchups. Oncrawl automates it in the cloud with AI bot tracking built in. Screaming Frog does it locally, manually, at a fraction of the price, and out-scores Oncrawl in our own review.
Oncrawl
Screaming Frog SEO Spider- Screaming Frog scored 9.1 overall in our review against Oncrawl's 8.0, driven by a value-for-money score of 9.5 versus Oncrawl's 7.2.
- Both tools include server log analysis: Oncrawl as an always-on, scheduled cloud feature, Screaming Frog as a manual upload you run yourself, included in the standard £199/year license at no extra cost.
- Oncrawl tracks AI bot crawl activity from GPTBot, ClaudeBot, and PerplexityBot specifically, and separately monitors whether pages are cited in AI-generated answers. Screaming Frog's log analysis maps generic search bot crawl frequency; it does not identify or track named AI bots.
- Screaming Frog is a desktop app (Windows, macOS, Linux) with no per-seat SaaS pricing, £199/year for a single unlimited-URL license. Oncrawl is cloud-hosted with enterprise-only, contact-for-pricing access.
- Screaming Frog includes custom data extraction via XPath, CSS selectors, and regex on every paid license. Oncrawl's public feature set does not describe an equivalent custom extraction capability.
- Oncrawl runs scheduled, automated crawls with regression alerting built in. Screaming Frog crawls are run on demand from the desktop app; scheduling cloud crawls is not part of the core product.
- Screaming Frog offers a free version capped at 500 URLs to test the tool before buying. Oncrawl has no free tier or self-serve trial of any kind.
Oncrawl and Screaming Frog SEO Spider are an unusually direct comparison for this category because they overlap on a feature most competitors do not touch: server log analysis. Oncrawl treats log ingestion as a core, always-on part of a hosted cloud platform, with scheduled crawls, automated alerting, and a dedicated AI bot tracking layer that watches GPTBot, ClaudeBot, and PerplexityBot crawl activity. Screaming Frog includes log analysis in its standard desktop license too, at £199/year with no crawl limit, but it is a manual upload-and-analyze workflow rather than a continuously running one, and it has no equivalent AI bot or AI-answer citation tracking. The price gap is the real story: Screaming Frog scored 9.1 in our review against Oncrawl's 8.0, and costs a fraction of an enterprise contract that requires a sales demo to even see a number.
The tools at a glance
Oncrawl
Cloud-based technical SEO platform combining crawl data, log analysis, and AI bot tracking.
Oncrawl runs as a hosted platform rather than software you install. Scheduled crawls execute automatically on whatever cadence a site's update frequency justifies, and server log ingestion is a core, always-on part of the product, showing exactly which URLs search engines are visiting and where crawl budget is being wasted, without anyone needing to manually upload a log file.
The AI-specific layer goes further than Screaming Frog's log analysis: Oncrawl identifies and tracks crawl requests from named AI bots, GPTBot, ClaudeBot, and PerplexityBot, and a separate feature checks whether pages are actually showing up as citations in AI-generated answers. Automated alerts flag regressions, a spike in 404s, a drop in indexed URLs, as they happen rather than at the next manual review.
What Oncrawl does not offer is Screaming Frog's price point or its custom extraction flexibility. There is no free tier, no published pricing, and no self-serve signup, access requires a sales demo. For a solo consultant or small agency, that alone rules Oncrawl out regardless of feature depth.

Screaming Frog SEO Spider
The industry-standard desktop crawler for technical SEO audits.
Screaming Frog SEO Spider runs locally on your machine rather than in the cloud, which means data stays on your own hardware and crawl performance scales with your own specs rather than a subscription tier. The paid license removes the free version's 500 URL cap entirely for £199 a year, covering redirects, canonicals, hreflang, structured data, and JavaScript rendering via Chromium.
Log analysis is included in the standard license at no extra charge, which most competitors either omit or charge separately for. Upload Apache, Nginx, or IIS logs and the Spider maps crawl frequency against your site structure to surface where budget is being wasted. It is a manual, on-demand process rather than Oncrawl's always-on ingestion, and it tracks generic search bot activity rather than identifying specific named AI bots.
What the Spider does not do is anything Oncrawl automates in the cloud: no scheduled crawls, no alerting, no dedicated AI bot identification, and no AI-generated answer citation tracking. In exchange, custom extraction via XPath, CSS selectors, and regex ships on every paid license, letting advanced users pull any data point from page source, a flexibility layer Oncrawl's public feature set does not describe.

Oncrawl tracks named AI bots and answer citations. Screaming Frog's log analysis does not identify AI crawlers specifically.
Oncrawl's AI bot tracking identifies GPTBot, ClaudeBot, and PerplexityBot crawl activity by name and separately monitors whether pages are cited in AI-generated answers, but that capability sits inside a full enterprise platform with no published price. Screaming Frog's log analysis is genuinely strong for the price, £199/year with no extra charge, but it maps generic search bot crawl frequency and does not identify or separate AI bot traffic, let alone track AI citations. AI Peekaboo covers the citation side directly as a self-serve product, tracking brand mentions across ChatGPT, Gemini, Perplexity, and Google AI Overviews from $50/month with a read and write API on every plan, without needing either an enterprise contract or a desktop log upload workflow.

Screaming Frog SEO SpiderOncrawlOncrawlScreaming Frog SEO SpiderScreaming Frog SEO SpiderOncrawlScreaming Frog SEO SpiderThis is the rare comparison in this category where the cheaper tool also scores higher in our review, 9.1 for Screaming Frog against 8.0 for Oncrawl, and it is not close on value for money, 9.5 versus 7.2. The gap Oncrawl actually closes is automation and AI-bot specificity: scheduled crawls that run without anyone remembering to trigger them, log ingestion that happens continuously instead of on manual upload, and AI bot tracking that names GPTBot and ClaudeBot rather than lumping all crawler traffic together. For a large enterprise site where crawl budget waste has real dollar impact, that automation can justify the sales conversation. For nearly everyone else, Screaming Frog does more of the same core job at roughly 1% of what an enterprise contract typically costs.
Bottom line
Buy the Screaming Frog license. At £199/year with unlimited URLs, JavaScript rendering, and server log analysis included, it beats Oncrawl on our own scoring and on price by a wide margin, and the free version is good enough to confirm that before paying anything. Book the Oncrawl demo only if the specific requirement is scheduled, automated crawling at enterprise scale with named AI bot tracking and AI-generated answer citation monitoring, capabilities Screaming Frog genuinely does not have. Most agencies and in-house teams outside the largest enterprise sites will get more real value per pound from Screaming Frog.
Frequently asked questions
Does Screaming Frog do server log analysis like Oncrawl?
Yes, and it is included in the standard £199/year license at no extra cost, which most competitors either omit entirely or charge separately for. The difference is automation: Screaming Frog's log analysis is a manual upload you run yourself, while Oncrawl ingests logs continuously as an always-on cloud feature.
Is Oncrawl worth the enterprise price over Screaming Frog in 2026?
Only if the specific need is scheduled, automated crawling and log ingestion with named AI bot tracking (GPTBot, ClaudeBot, PerplexityBot) and AI-generated answer citation monitoring. Screaming Frog scored higher in our own review, 9.1 versus 8.0, and costs a fraction of an enterprise contract, so for most technical SEO work outside large-scale automation, it delivers more value per pound.
Can Screaming Frog track AI bots like GPTBot the way Oncrawl does?
No, Screaming Frog cannot identify named AI bots: its log analysis maps crawl frequency against your site structure using standard log files, but it does not separate GPTBot or ClaudeBot traffic from other crawlers. Oncrawl tracks GPTBot, ClaudeBot, and PerplexityBot specifically and separately monitors whether pages are cited in AI-generated answers.
Is Screaming Frog a cloud tool or does it require installation?
Screaming Frog SEO Spider is a desktop application for Windows, macOS, and Linux, installed and run locally on your own machine. Oncrawl works the opposite way, as a fully cloud-hosted platform with scheduled crawls and no software to install.
How many URLs can Screaming Frog crawl compared to Oncrawl?
The Screaming Frog free version caps at 500 URLs; the paid license at £199/year removes that limit entirely, constrained only by your local machine's resources. Oncrawl is built as a cloud platform specifically to handle very large crawls without local hardware constraints, though it discloses no specific URL limits publicly.
Is there a cheaper way to track AI answer citations than Oncrawl's enterprise platform?
AI Peekaboo tracks brand mentions across ChatGPT, Gemini, Perplexity, and Google AI Overviews as a self-serve product starting at $50/month with a read and write API on every plan. Oncrawl's AI-generated answer visibility covers similar ground but only inside a full enterprise crawl platform with contact-only pricing, and Screaming Frog has no AI citation tracking at all.
