Overview

Horseman is a configurable web crawling tool automating site analysis through custom JavaScript snippets, letting users interact with websites to extract and manipulate data across entire domains rather than one page at a time.

Horseman targets frontend developers, performance analysts, digital agencies, accessibility experts, SEO specialists, and JavaScript engineers. Pricing runs through GitHub Sponsors: Sponsor, $5/month, 1 device. Sponsor++, $10/month, 3 devices. Sponsor+++, custom pricing. All tiers include a GitHub sponsor badge and early access to other development tools.
