Beam Us Up vs Sitebulb (2026): which should you pick?

Pick Beam Us Up if

• Fits if you want a site crawler without a subscription
• Works for developers who want to run crawls from the command line or a server

Look elsewhere if

• Not for you if you need support you can count on, as it's one developer's project answered through site comments
• Too light for very big audits, since crawls use up to half your computer's memory and Excel exports stop at 65,536 rows
• Skip it if you want crawls run in the cloud, as it only runs on your own computer
• Watch out: its own site says paid crawlers such as Screaming Frog and Netpeak do more

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
