The cloud alternative to Netpeak Spider
Netpeak Spider is a fast, configurable desktop crawler with a one-time licence. CrawlX runs the same depth of technical audit in the cloud — no install, no memory ceiling — then ranks every issue by impact and ships the fix as a pull request.
Netpeak Spider is a capable desktop SEO crawler with a loyal following — it's fast, highly configurable, and its one-time lifetime licence is genuinely good value. CrawlX takes a cloud-native path: no install, no memory ceiling on big sites, issues ranked by estimated impact, and fixes drafted as GitHub pull requests. Here's an honest, side-by-side look at where each one fits.
