Reddit Subreddit Users Scraper

Extract all unique users from a subreddit — including post authors and comment authors — with optional full profile enrichment (karma, bio, account age, Gold/Mod status, and more).

Ideal for audience research, community analysis, influencer identification, and building contact lists from Reddit communities.

Features

• Post authors — Collects every post author from the scanned posts
• Comment authors — Optionally scans each post's comments to collect all comment authors (finds significantly more unique users)
• Deduplication — Each unique username appears only once, with a count of how many posts/comments were found
• Profile enrichment — Optionally fetches full profile data for each unique user: karma, bio, account age, Gold/Mod/Employee status
• Two-phase architecture — Phase 1 collects users from subreddit; Phase 2 (optional) enriches with profile API data
• Configurable depth — Control how many posts to scan with maxPosts
• Stealth mode — Random user agents and fingerprinting to avoid rate limits
