Reddit Subreddit Scraper - Community Info, Rules, Similar Subs & Comments

Overview

The Reddit Subreddit Scraper extracts rich community metadata for one or more subreddits: about/info, moderation rules, similar communities, and optionally recent comments. Use it to understand community size, positioning, guidelines, and adjacency before you engage or scrape posts at scale.

Built for community strategists, brand safety teams, researchers, and growth operators evaluating where to participate. Returns clean, structured JSON with type-tagged rows (info, rule, similar, comment, error) so you can filter datasets easily.

Pair it with the Subreddit Posts Scraper when you need both community context and feed content.

Features

• Batch multiple subreddits per run
• Core community info: title, description, subscribers, active users, NSFW, icons, banners
• Optional rules export (includeRules)
• Optional similar/related communities (includeSimilar)
• Optional comments listing (includeComments) with maxResults cap
• Absolute Reddit URLs for community pages
• Concurrent processing with per-subreddit error isolation
• Premium structured JSON for BI and research workflows

Input

Parameter	Type	Required	Default	Description
subreddits	array of strings	Yes	—	Subreddit names (askreddit or r/askreddit).
includeRules	boolean	No	true	Fetch community rules.
includeSimilar	boolean	No	true	Fetch similar/recommended subreddits.
includeComments	boolean	No	false	Fetch comments from the community.
maxResults	integer	No	50	Max comments when includeComments is true (1–500).

How parameters affect the run: Disabling rules/similar reduces API calls. Enabling comments adds listing pagination up to maxResults. Info is always collected for each valid subreddit.

  "subreddits": ["marketing", "r/PPC"],
