Postsnag

PostSnag is a Chrome extension with a dashboard for marketers, agencies, and creators who need real Facebook post performance, not just follower counts. It captures posts as they appear while you scroll, then organizes them so you can spot patterns, bookmark what works, and export data for further analysis.

• Auto-capture while you scroll collects posts and metrics from profiles, pages, and groups
• Save to boards/dashboard bookmark individual posts or entire profiles for later review
• Organize by group keep captures separated by the Facebook groups they came from
• Rank by performance sort posts by likes, comments, shares, or video plays
• Discovery feed (outliers) surfaces viral outliers across the profiles you track
• Built-in analytics shows post-type breakdowns and engagement composition for each profile
• AI-ready exports download captured post data as JSON, Markdown, or Excel-ready formats

It’s built for competitive research and content planning workflows where you want to study what’s getting engagement right now. If you’re tracking specific creators, competitor pages, or niche communities, you can capture their posts, then revisit the saved items when you need reference or inspiration.

PostSnag’s approach is based on reading what’s already visible in your browser session. It doesn’t require proxies or automated scraping requests, and the captured fields include post type, likes, comments, shares, video plays, full captions, and the exact date and time posted.
