Reddit Community Finder

What does it do?

Reddit Community Finder discovers and extracts metadata about Reddit subreddits based on keyword searches. It uses both Reddit's public JSON API and HTML search to collect subreddit names, subscriber counts, active user counts, descriptions, titles, NSFW flags, creation dates, and community types. The scraper deduplicates results, filters by minimum subscriber count, and handles pagination across both data sources to build comprehensive subreddit databases.

Why use this scraper?

Reddit hosts over 100,000 active communities spanning every topic imaginable, from technology and science to hobbies and local communities. This scraper enables audience research, niche community discovery, competitor monitoring, and marketing opportunity identification at scale. Whether you are finding subreddits for product promotion, researching community sizes and engagement levels for content strategy, identifying niche audiences for targeted advertising, or mapping the Reddit community landscape for a specific industry, this tool provides structured data efficiently.

1. Navigate to the Reddit Community Finder on Apify.
2. Enter search keywords for the types of subreddits you want to find.
3. Set the minimum subscriber count to filter small communities.
