Oncrawl vs Sitebulb in 2026: enterprise log analysis vs a self-serve crawler built for hints, not sales calls
One is a demo-gated platform pairing crawl data with server logs and AI bot tracking. The other is an $18-a-month desktop and cloud crawler built around 300+ prioritized hints and free JavaScript rendering.
Oncrawl
Sitebulb- Sitebulb publishes pricing from $18/month and includes a 14-day free trial on every tier. Oncrawl publishes no pricing at all and requires a sales demo before you see a number.
- Oncrawl tracks AI bot crawl activity from GPTBot, ClaudeBot, and PerplexityBot and monitors whether content is cited in AI-generated answers. Sitebulb has no AI-answer visibility tracking; its only AI-related feature is a waitlisted MCP server for querying audit data.
- JavaScript crawling costs nothing extra on any Sitebulb plan, including Lite. Oncrawl doesn't break out JS rendering as a line item since it sells a single custom Enterprise package.
- Server log analysis is a core part of Oncrawl, built into the base product. Sitebulb doesn't offer log file analysis at all; it is a pure site crawler.
- Sitebulb Cloud scales to 10 million URLs per audit. Sitebulb Desktop Pro caps at 500,000, and Oncrawl doesn't publish a URL ceiling for its Enterprise plan.
- Sitebulb's 300+ prioritized Hints come with built-in educational context explaining why each issue matters, useful for onboarding junior staff. Oncrawl assumes a practitioner who already knows how to read crawl and log data.
- Oncrawl's REST API is a genuine strength for feeding crawl, log, and AI bot data into Looker Studio, BigQuery, or Tableau. Sitebulb's integrations run through GA, GSC, Google Sheets, and Data Studio rather than a documented open API.
Oncrawl and Sitebulb both run technical SEO crawls, but they are built for different buyers entirely. Oncrawl bundles crawl data with server log analysis and tracks AI bot activity from GPTBot, ClaudeBot, and PerplexityBot, plus whether content actually gets cited in AI-generated answers, and all of it sits behind a single Enterprise tier with no published price and a required demo. Sitebulb skips the sales call: Lite starts at $18 a month, JavaScript rendering is included on every plan instead of sold as an upgrade, and the 300+ prioritized Hints system explains why each issue matters rather than just listing errors. If the actual problem is crawl budget waste or AI crawler behavior at enterprise scale, Oncrawl does something Sitebulb has no answer for. If the goal is running an audit this afternoon without talking to sales, Sitebulb is built for exactly that.
The tools at a glance
Oncrawl
Cloud-based technical SEO platform combining crawl data, log analysis, and AI bot tracking.
Oncrawl is a cloud technical SEO platform built around three data sources: crawl data, server log data, and performance data. Most crawlers describe what is on a site; Oncrawl adds what search engines and AI crawlers are actually visiting and how often, and log analysis is built into the core product rather than sold as an add-on, which is what separates it from a standard crawler at a similar price tier.
Oncrawl has kept pace with the shift toward AI search on two fronts: it tracks AI bot crawl activity from GPTBot, ClaudeBot, and PerplexityBot at the URL level, and it includes AI-generated answer visibility monitoring, tracking whether content is actually cited in AI responses. That second piece is a real citation-tracking capability, not just a crawl-access log, and it sits alongside scheduled crawls, redirect and canonical checks, and automated regression alerts.
None of it is available without a sales conversation. Oncrawl sells a single custom Enterprise tier with no published price and no self-serve signup, and the platform requires real configuration to get value from, which teams without dedicated technical SEO staff may not use to its potential. For large sites where log analysis and AI bot tracking are genuine requirements, the REST API, which integrates with Looker Studio, BigQuery, and Tableau, is the payoff for going through that process.

Sitebulb
Website crawler for technical SEO audits with prioritized hints and visual reporting
Sitebulb is built around telling SEOs what to do with crawl data, not just collecting it. The tool ships with over 300 prioritized Hints across technical categories, each ranked by severity with in-built educational context, so teams can go straight to the issues most likely to move rankings instead of interpreting a raw spreadsheet of errors themselves.
The product ships in two modes. Sitebulb Desktop runs locally, which suits agencies and freelancers who want full control over crawl settings without a cloud dependency. Sitebulb Cloud adds team collaboration, automated recurring crawls, unlimited projects, and crawl capacity up to 10 million URLs per audit, targeting agencies working large enterprise accounts, and the two products sync natively so teams can trigger cloud crawls from the desktop interface.
JavaScript rendering is included on every plan, including the $18/month Lite tier, at no extra cost, which stands out since several competitors charge separately for it or gate it behind a pricier plan. What Sitebulb does not offer is server log analysis or any form of AI-answer citation tracking; its only AI-related feature is a Model Context Protocol server, still on a waitlist, that would let AI tools query existing audit data rather than track AI search visibility.

Considering AI Peekaboo alongside Oncrawl and Sitebulb?
Oncrawl does track whether content is cited in AI-generated answers, but that capability sits inside a single Enterprise tier with no published price and a mandatory sales demo. Sitebulb has no AI-answer visibility tracking at all, only a waitlisted MCP server for querying audit data. AI Peekaboo is a dedicated AI visibility platform with a read and write API on every plan from $50/month, tracking ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode, with no sales call required to get started.

OncrawlSitebulbOncrawlSitebulbOncrawlSitebulbOncrawlThese two aren't really competing for the same budget. Sitebulb is a crawler you buy the way you'd buy most SaaS tools: pick a tier, pay by card, start crawling in the same session. Oncrawl is a data platform you get introduced to by a salesperson, and the payoff for that friction is server log analysis and AI bot and citation tracking that Sitebulb simply doesn't build. For the large majority of freelancers, small agencies, and in-house teams running an ordinary technical SEO practice, Sitebulb's $18-to-$42 range covers the job well and throws in JS rendering that some competitors charge extra for. Oncrawl only earns its keep once log analysis or AI crawler visibility becomes a real requirement rather than a nice-to-have, and the site is large enough that enterprise pricing is a rounding error next to the cost of an unaddressed crawl budget problem.
Bottom line
Buy Sitebulb if you want a capable technical SEO crawler you can be running audits with before lunch, especially at the Pro tier's $42/month for sites under 500,000 URLs. Book the Oncrawl demo if server log analysis or AI bot and citation tracking are must-haves and you're prepared to negotiate enterprise pricing to get them. Teams that want AI-answer visibility without an enterprise sales process are better served pairing either crawler with a dedicated AI visibility tool.
Frequently asked questions
Does Sitebulb have server log analysis like Oncrawl?
Sitebulb does not offer server log analysis on any plan; it is built purely as a site crawler. Oncrawl treats log analysis as a core feature, mapping exactly which URLs search engines and AI crawlers visit and how crawl budget is allocated, which is the main reason enterprise technical SEO teams pick it over a standard crawler.
Can Sitebulb track whether my content is cited in AI-generated answers?
Sitebulb has no AI-answer citation tracking of any kind. Its only AI-related feature is a Model Context Protocol server, still on a waitlist, that would let AI tools query your existing audit data, which is a different thing from monitoring whether ChatGPT or Perplexity actually cite your pages. Oncrawl does track AI-generated answer visibility alongside AI bot crawl activity from GPTBot, ClaudeBot, and PerplexityBot.
Why does Oncrawl not publish pricing while Sitebulb does?
Oncrawl sells a single Enterprise tier through a demo-first sales process aimed at large sites with complex log-analysis needs, so pricing is negotiated rather than listed. Sitebulb is built for self-serve signup, with Lite at $18/month, Pro at $42/month, and Cloud starting at $125/month, all backed by a 14-day free trial with no credit card required.
Is Sitebulb's free JavaScript crawling actually comparable to what enterprise tools offer?
Sitebulb includes JavaScript rendering on every plan, including the $18/month Lite tier, at no additional charge, which is unusual since several competing tools gate JS crawling behind a pricier plan or a separate add-on. Oncrawl does not publish JS-rendering details as a distinct feature since it sells one custom Enterprise package rather than tiered plans.
Which tool handles very large sites better, Oncrawl or Sitebulb?
Sitebulb Cloud crawls up to 10 million URLs per audit, well beyond the 500,000-URL cap on Sitebulb Desktop Pro. Oncrawl is also built as a cloud platform for large-scale crawls and pairs that with server log analysis, but it does not publish a specific URL ceiling for its Enterprise tier, so limits need confirming during the sales process.
Do I need Oncrawl if I already use Sitebulb for client audits?
Only if log file analysis or AI bot and citation tracking become a real requirement for a specific client, since Sitebulb offers neither. Most agencies running standard technical audits across mid-sized client sites will find Sitebulb's Pro or Cloud tier sufficient without adding a second, enterprise-priced tool.
