What Serposcope is

Serposcope is a free rank-tracking application for monitoring website positions in search engines and supporting SEO work. It provides rank tracking and API access across Linux, macOS, Windows, web, API, and self-hosted setups. The installed application runs a web service, normally available at http://127.0.0.1:6333/. Serposcope 3 uses SQLite, and its API is available but not yet documented; MySQL support was removed in version 3. SERP scraping integrations include Scraping Ant and Space Serp, while captcha integrations include capmonster.cloud, Anti-Captcha, 2captcha, and imagetyperz. Third-party scraping APIs are described as faster and more reliable, but they are not free. The download page warns that Serposcope is no longer supported and may not work, with version 3.5 listed as latest. Security guidance recommends HTTPS and reverse-proxy authentication. The macOS package lacks an official Apple developer certificate.
