Reddit Comments Scraper: Whole Threads & Replies

What does Reddit Comments Scraper do?

Paste Reddit post links and it exports each post's comment thread: every comment and reply with its text, author, score, date, depth, parent, root comment and reply count, right after the post itself: Reddit's first answer in its own order, then (on big threads) the rest as they're read. Up to 1,000 comments per post by default (more if you raise it), many posts per run, first rows in seconds. No login, no browser, no cookies.

These are real rows from the prefilled run (2 threads, 49 comments each: r/gamedev "Anyone else still uses little to no AI to code?" and r/technology's self-checkout thread):

What do you get from a Reddit thread?

• Every comment and reply, up to Max comments per post: Reddit hides long threads behind "more replies" links; the Actor opens them for you.
• The thread's shape: depth, parentId and rootCommentId on every comment, and numberOfReplies when the comment's replies were read, so you can rebuild the tree or keep only top-level comments.
• The post itself first: title, text, score, upvote ratio, comment count, subreddit, author, flair, media.
• Any sort: Best, Top, New, Controversial, Old or Q&A, as on Reddit, and a reply depth from 1 (top-level only) to 10.
• One comment's thread: a link to a single comment reads that comment with its replies.
• Subreddit or search links: their top posts, each with its comments.

Use cases

• Customer and product research: what people actually think, in their own words, under a post about your product or a competitor.
• Sentiment and topic analysis: whole discussions with scores, ready for an LLM or a spreadsheet.
• AI training and RAG datasets: conversations with parent/child links intact.
• Content and community work: the best-voted answers to a question, replies included.

How much does it cost to scrape Reddit comments?

You pay per result in your dataset: a comment or a post, both at the same price.

Apify plan	Price per 1,000 results
Free	$0.59
Starter	$0.49
Scale	$0.45
Business	$0.39

Each comment and post is charged once per run. There's no start fee, and the run stops at your spending limit, so set Max comments per post to what you need.

Input

The prefill reads 2 threads with 49 comments each. To change it:

• Post URLs: one post link per row: reddit.com/r/.../comments/..., old.reddit.com, redd.it short links, or a link to one comment.
• Max comments per post: 1,000 by default; Reddit's biggest threads have tens of thousands, and the field goes to 100,000. Measured on 2026-10-22: 1,000 comments of a 3,141-comment r/technology thread took an 18 s run (191 Reddit calls) and cost $0.49 at the Starter price; very large asks take longer.
• Comment sort and Reply depth: as on Reddit.
• Below the first screen: how many posts to read from a subreddit or search link, Filters (posted after or before a date, NSFW) and Advanced (a total cap for the run, proxy).

{
  "startUrls": [
    { "url": "https://www.reddit.com/r/AskReddit/comments/<post id>/<title>/" },
    { "url": "https://redd.it/<post id>" }
  ],
  "maxCommentsPerPost": 5000,
  "commentSort": "top"
}

Output

Every row goes to one dataset, where dataType says what it is: post or comment. Each post is followed by its comments in thread order. The Output tab shows a comments table, a posts table and both together. Download as JSON, CSV, Excel or HTML, or read it through the Apify API.

A reply from the prefilled run (shortened):

Is it legal to scrape Reddit comments?

The Actor reads only public Reddit threads that anyone can open without an account. It never logs in and skips private and quarantined communities. If your results include personal data, you're responsible for handling it lawfully (for example under GDPR).

FAQ

Why fewer comments than the post's comment count? Reddit's count includes comments that were removed since, and the run stops at Max comments per post and Reply depth. Deleted comments that still have replies come as [deleted] rows, so the tree stays whole.

What if Reddit fails in the middle of a thread? Each thread page is tried up to 4 times, each time from a new IP. If one still fails, the comments read so far stay, and the run's status and OUTPUT (commentsIncomplete) name the posts whose threads stopped early.

Is it fast? The prefilled run (2 posts, 98 comments) took 6 and 27 seconds on Apify in two runs, the first row 2.7 and 5.4 seconds after the start (256 MB, datacenter proxy, October 22, 2026). Big threads come in batches as Reddit's thread pages and their "more replies" parts load: 1,000 comments took 191 calls.

Does my Apify plan matter? Only for very large runs. Reddit allows 100 requests per IP every 10 minutes and the run uses your plan's datacenter proxy IPs (5 on Free, more on paid plans). If they are all used up, the run waits for Reddit's window to reset and says so in its status.
