OG Watchdog

Monitor your site's OG/social preview tags automatically and alert when they break

Problem

When a site's OG tags (title, description, image, Twitter card, dimensions) break or go missing, social link previews look bad—but nobody checks proactively, so issues go unnoticed for a long time. A SaaS founder floated exactly this: paste a URL to check all OG tags, with a paid tier scanning daily and alerting when something breaks.

Solution

A lightweight monitoring service: add your key URLs, it periodically fetches and parses OG/Twitter tags, renders share previews for major platforms, and alerts via email/Slack when titles, descriptions, images, or dimensions go wrong. Historical snapshots help pinpoint when it broke.

Users

Indie developers, small-team growth/marketing folks, content sites and e-commerce operators

MVP

Paste URL for instant OG audit; add monitored URL list; daily scheduled scans; email alerts on anomalies; rendered share preview screenshots

Revenue

Free for 3 URLs; subscription unlocks more URLs, Slack/Webhook alerts, history diffs, team seats

Why now

Social sharing remains a key traffic source but OG issues are hidden and intermittent—a classic small-pain, high-automation niche a solo dev can ship in weeks and easily promote through the product itself
