The best free Sitebulb alternative
Crawly is a free, native macOS SEO crawler. No monthly subscription. No page cap. And it includes features Sitebulb does not have.
Why choose Crawly over Sitebulb?
Sitebulb is a respected SEO crawler with strong visualisations and a loyal user base. But at £13.50 per month (or more for agency plans), it adds up quickly - especially for freelancers, smaller agencies, or in-house teams that only need auditing capability occasionally.
Crawly is free. No subscription, no per-seat pricing, no features locked behind a paywall. It is a universal Mac build - no Java runtime, no browser tab to manage - and runs on both Apple Silicon and Intel Macs without Rosetta.
It also includes something neither Sitebulb nor any other paid crawler offers: a built-in Claude Code MCP integration. Connect Crawly to your AI coding tool and query your crawl data in plain English from your terminal. Ask what the top issues are, which pages are non-indexable, or what changed between two crawls - without touching a spreadsheet.
