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

Pick Checkbot if

• Fits if you check a site of under 100 URLs for broken links and bad markup before launch
• Works for developers testing a staging or localhost site, on the paid plan

Look elsewhere if

• Tight if your site runs past 100 URLs, as the free plan stops there and shows ads
• Watch out: it doesn't run JavaScript, so content added by scripts isn't checked
• Watch out: CSV and PDF exports, localhost and password-protected crawls all need Professional
• Pricey if you pay month to month, at $15 against $10 billed yearly, and a plan covers one person
• Not for you if you're not on Chrome, as the FAQ says there's no other browser version

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

Checkbot

• It runs only in Google Chrome; the FAQ says there is no Firefox or other browser version.
• The free plan stops at 100 URLs per crawl and shows ads; localhost crawls and exports need Professional.
• It does not execute JavaScript while crawling, so content added by scripts is not tested.
• A subscription covers one person; new customers can get a full refund within 14 days.

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.

Checkbot

Site-wide crawl

Crawls hundreds of pages at once from a start URL and scores them against 50+ rules drawn from Google, Mozilla and W3C guidance.

SEO checks

Finds broken links, missing or long titles and descriptions, duplicate content, canonical problems, missing image alt text, temporary redirects and sitemap issues.

Speed and security checks

Flags redirect chains, unminified or render-blocking CSS and JavaScript and missing caching or compression, plus HTTPS, mixed content and security header gaps.

Staging and localhost sites

Crawling runs on your own machine, so the paid plan can test localhost, private-network and HTTP Auth password-protected sites.

Crawl filters and quick rechecks

Limit a crawl by subdomain, folder, depth, pattern or file type, and recrawl a single page to confirm a fix.

PDF reports and CSV export

The Professional plan exports problem lists to CSV in bulk and produces PDF summary reports for clients or teammates.

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.
