Deep Dive: Switching from Sitebulb to SiteOne Crawler
Trade-offs, installation & data architecture
What you trade away
Its fix-first scoring is useful, but its prioritization and guided evidence are less polished than Sitebulb's.

Download a prebuilt desktop or CLI binary for Windows, macOS or Linux
What it takes to run
None for ordinary crawling; JavaScript rendering needs Chrome or Chromium, or the one-time headless-shell download
Where your data lives

Why fork SiteOne Crawler instead of vibe-coding a Sitebulb clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Sitebulb, crawl an owned site and turn technical findings into prioritized, evidenced hints. The hard boundary is rule depth, visualization, reporting, javascript crawling, and agency workflow, plus crawl scale, rule depth, and operational polish.
