Comment System Detector

Detect comment systems and determine whether visitors can currently comment on a website.

Overview

Analyzes supplied websites and eligible internal pages to identify comment systems and their current state. Results include the detected provider, commenting state, form availability, confidence score, and supporting evidence.

Problem

Comment functionality can appear on article pages rather than homepages and may use different providers, custom widgets, login requirements, or disabled states.

Solution

Uses bounded internal crawling to locate relevant pages, detect comment systems, determine their state, and produce one structured result per website with confidence and supporting evidence.

How it works

- Comment provider detection - Commenting state detection - Comment form availability detection - Login requirement detection - Confidence scoring - Supporting detection evidence - Bounded internal-link crawling - Article-like link prioritization - robots.txt-aware crawling - Stops crawling a site after successful detection - One final structured result per unique site
