SEOnaut vs Sitebulb (2026): which should you pick?

Pick SEOnaut if

• Fits if your site fits in 500 URLs and you want a free hosted crawler
• Works for teams that want to run their SEO crawler on their own server

Look elsewhere if

• Tight if you outgrow Growth's 5 projects of 10,000 URLs, as more means emailing the developer
• Watch out: self-hosting needs Docker or Go plus MySQL, and HTTPS through a reverse proxy
• Not for you if you want support beyond email, as self-hosted copies go through GitHub Issues
• Skip it if you want free audits on a schedule, as only the paid Growth plan lists recurring audits

Pick Sitebulb if

• Fits if you want each audit finding ranked by priority with an explanation of what to do
• Works for freelancers auditing sites under 10,000 URLs, from $180 a year on Lite

Look elsewhere if

• Tight if your site is big, as Lite stops at 10,000 URLs per audit and lacks scheduling, comparisons and several reports
• Pricey if you want it in the browser, as Sitebulb Cloud starts at $125 a month and needs at least 2 users
• Skip it if you need keyword research or rank tracking, as it only audits
• Watch out: desktop crawls depend on your computer; Pro's default cap is 500,000 URLs, and more users are from $11 a month each
• Watch out: there's no free plan after the 14-day trial, and paying by invoice or purchase order is for yearly plans only

SEOnaut

• The hosted Growth plan stops at 5 projects and 10,000 URLs each; larger needs are handled by emailing the developer.
• Self-hosting needs Docker or Go plus a MySQL database, and the project recommends adding HTTPS through a reverse proxy.
• Support is by email for the hosted service and through GitHub Issues for self-hosted copies; there is no forum.
• Of the hosted plans, only the paid Growth plan lists recurring audits; Lite crawls run on demand.

Sitebulb

• Lite caps each audit at 10,000 URLs and lacks scheduling, comparisons and several report types.
• Desktop crawls are limited by the computer: Pro's default cap is 500,000 URLs, raisable to 2 million.
• Sitebulb Cloud is priced separately, from $125 a month, and needs at least 2 users.
• Purchase order and invoice payment is only for yearly plans.

SEOnaut

Issues ranked by severity

Each crawl produces a report that groups problems as critical, high or low, from broken links and redirect loops to duplicate titles and descriptions.

On-page and content checks

Audits titles, descriptions, heading order, hreflang tags, image alt text and file size, thin or duplicated content, canonicals and HTTP pages.

Crawl settings

The crawler can ignore robots.txt, follow nofollow links, include sitemaps and subdomains, check external links and log in to staging sites with HTTP Basic Auth.

Site structure and dashboard

Spots orphan and dead-end pages, checks response time and timeouts, and charts site health over time on a visual dashboard.

WACZ archives

Saves a crawled site as a WACZ web archive, keeping pages and assets for offline review or record-keeping.

Self-hosting with Docker

Written in Go with a MySQL database; the project publishes a Docker image and a Docker Compose file, and the interface can be translated.

Sitebulb

Prioritized hints

Each audit flags issues against 100+ hints on Lite or 300+ on Pro, ranked by priority and explained in plain terms.

JavaScript crawling

Render JavaScript-heavy sites during a crawl on every plan, at no extra cost.

Audit comparison and scheduling

On Pro, compare audits to see what changed and schedule audits to run automatically, with auto-export to Google Sheets.

Crawl maps and reports

See site structure as visual crawl maps, and on Pro produce customized PDF reports for clients.

Pro-only checks

Pro adds performance and mobile, structured data, hreflang, spelling, accessibility and AMP reports.
