Sitebulb and Sitemap Generator both crawl websites and produce sitemap files. That's where the similarity ends. Sitebulb is a professional-grade technical SEO auditing platform with award-winning visualizations, client-ready PDF reports, and 300+ audit checks. Sitemap Generator is a focused cloud tool built for non-technical site owners who need a valid XML sitemap and URL health monitoring — nothing more, nothing less.
Neither tool is objectively "better." They serve different users. The question is which one matches your actual workflow.
The short answer
Choose Sitebulb if you're an SEO professional or agency needing deep technical audits, JS rendering, and client-ready visual reports. Choose Sitemap Generator if you're a site owner or marketer who needs a working XML sitemap, 404 monitoring, and scheduled auto-refresh — without the complexity or cost of a professional crawler.

What Makes Sitebulb Different
Sitebulb was founded in 2017 by the creators of URL Profiler and has won Best Search Software Tool and Best Software Innovation at the UK and US Search Awards. Its standout features are the prioritized "Hints" system — every audit finding is ranked by severity with plain-English fix guidance — and the Crawl Maps, which use force-directed graph visualization to reveal site architecture problems at a glance. It also runs 50+ WCAG-level accessibility checks, something virtually no other sitemap or crawl tool offers.
The flagship JavaScript feature is "Response vs Render" — a side-by-side comparison of what the server sends vs. what Googlebot actually sees after JavaScript executes. For agencies auditing React or Angular sites, this is indispensable.
Where Sitebulb Is Clearly Better
- Technical audit depth. 300+ prioritized Hints with severity ratings and step-by-step fix documentation. Used by team leads to train junior SEOs.
- JavaScript rendering. Chromium-based Chrome Crawler with Response vs Render — the clearest view of how Googlebot sees a JS-heavy page.
- Crawl Maps. Force-directed visualizations that reveal orphan pages, crawl budget waste, and disconnected site clusters at a glance.
- Client-ready PDFs. Audit reports that non-technical stakeholders immediately understand without explanation — "Sitebulb basically writes the client presentation for you."
- Accessibility auditing. 50+ WCAG-level checks via Deque axe Rules — a capability no pure sitemap tool provides.
- Team collaboration (Cloud). Shared workspaces, simultaneous multi-user access, and Looker Studio dashboards for enterprise reporting.
Where Sitemap Generator Is the Better Choice
- No free tier for Sitebulb. Sitebulb offers a 14-day trial only. Sitemap Generator has a permanent free plan for users who need occasional sitemap generation.
- Price gap for non-agency users. Sitebulb Desktop starts at ~$13.50/month; Cloud starts at ~$120/month. Sitemap Generator is priced for individuals and small businesses, not for agency cost structures.
- Zero-install for non-technical users. Sitebulb Desktop requires installation. Even Sitebulb Cloud involves a setup layer that is more complex than a pure web app. Sitemap Generator requires nothing beyond a browser.
- Simpler scheduling. Sitebulb Desktop scheduling requires the machine to stay on — not a true cloud scheduler. Sitebulb Cloud solves this but at ~$120/month. Sitemap Generator's auto-refresh is server-side at all tiers.
- Plain-language health reports. Sitemap Generator's 404 and redirect reports are designed to be self-explanatory without SEO background. Sitebulb's Hints are excellent but still assume some familiarity with technical SEO concepts.

Frequently Asked Questions
Does Sitebulb have a free plan?
No — Sitebulb offers only a 14-day free trial (no credit card required, no auto-renewal). After the trial, a paid subscription is required. This is a key difference from tools like Screaming Frog (500-URL free tier) and Sitemap Generator (permanent free plan).
Does Sitebulb's desktop scheduling work automatically?
No — Desktop scheduling requires the machine to be powered on and Sitebulb running at the scheduled time. True server-side scheduling (where crawls run without your machine) requires Sitebulb Cloud, which starts at ~$120/month.
Can Sitebulb generate an XML sitemap?
Yes — Sitebulb generates XML sitemaps (including image and video sitemaps) as part of its crawl output. Sitemap configuration is detailed: you can set priority, crawl frequency, and include data from Google Search Console or GA. XML sitemap generation is a secondary feature, however — the primary product is the full technical SEO audit.
Is Sitebulb suitable for non-technical site owners?
Not primarily. While the Hints system makes findings more approachable than Screaming Frog, concepts like crawl budget, JS rendering, and canonical tags still assume SEO familiarity. Sitebulb is designed for SEO professionals. Non-technical site owners will get more value from a tool purpose-built for their use case.
