Reddit Scraper & API: Posts, Comment Trees, Search, Monitoring

Reddit Scraper collects Reddit posts and complete comment threads without login, cookies or API key. Give it subreddits, search queries, post URLs or usernames, and get posts, every comment with its exact parent and depth, user profiles and post or comment history, as JSON, CSV or Excel, or through the Apify API. It works as a Reddit API alternative for anyone who needs the whole conversation and wants to know when something went wrong.

Errors, duplicates and filtered posts are not charged, and a run that collects nothing costs only the start ($0.005 per GB of memory, 1 GB by default).

What you get

• Complete comment trees: on a 1,650-comment thread, 263 of 263 recent comments down to depth 12, each with parentId, depth and rootCommentId, so the thread can be rebuilt in a spreadsheet.
• Whole threads as Markdown for LLMs (outputFormat: threadMarkdown): one record per post with its comment tree, 7.2 times fewer characters than the same thread as JSON records, at the same price.
• Only what is new (onlyNew): schedule the Actor and each run returns and charges only posts and comments that earlier runs did not return.
• Search that contains your words: strict search keeps only posts with every word of your query, as whole words; rejected posts are not charged. Comment search finds comments anywhere on Reddit or in one subreddit.
• Media decoded on posts and comments: gallery images in order, MP4/HLS/DASH video URLs, polls, flair, edited and deleted status.

How to scrape Reddit

1. Add subreddits (technology, r/LocalLLaMA), search queries, post URLs or usernames.
2. Choose a sort and a time range, and whether to include comments.
3. Optionally filter by date, flair, post type, keywords to exclude, or turn on strict search.
4. Run, then export the dataset, or call it from the API, Make, Zapier, n8n or an AI agent through MCP.
5. To monitor, turn on "Only new since the last run" and add a schedule in Apify Console.

Input examples

The 50 best posts of a subreddit this week, each with its discussion as Markdown, for an LLM:

{
  "subreddits": ["LocalLLaMA"],
  "sort": "top",
  "timeFilter": "week",
  "maxPostsPerSource": 50,
  "includeComments": true,
  "maxCommentsPerPost": 200,
  "outputFormat": "threadMarkdown"
}

Latest posts of two subreddits from the past 7 days, questions only, without giveaways:

{
  "subreddits": ["selfhosted", "homelab"],
  "sort": "new",
  "postedAfter": "7 days",
  "maxPostsPerSource": 500,
  "flairs": ["Need Help"],
  "excludeKeywords": ["giveaway", "\"discount code\""]
}

Output example

A real comment from our benchmark thread, with the author replaced (some fields left out):

{
  "type": "comment",
  "id": "pd0smho",
  "url": "https://www.reddit.com/r/technology/comments/1wu4lnz/palantir_ceo_alex_karp_quietly_purchased_37000/pd0smho/",
  "postId": "1wu4lnz",
  "postTitle": "Palantir CEO Alex Karp quietly purchased 37,000 acres of forests in Sweden—and locals found out when hunters lost leases to use the property",
  "parentId": "t1_pd02xdu",
  "parentType": "comment",
  "rootCommentId": "pczzr78",
  "depth": 3,
  "subreddit": "technology",
  "author": "example_user",
  "body": "Not a Swede, but don’t want him there either. ",
  "createdAt": "2026-09-30T15:31:09Z",
  "score": 920,
  "scorePerHour": 8.72,
  "isDeletedOrRemoved": false,
  "scrapedAt": "2026-10-05T00:58:22Z"
}

The same kind of data as one Markdown record (threadMarkdown, the 2012 Obama AMA, shortened, commenters replaced):

{
  "type": "thread",
  "id": "z1c9z",
  "title": "I am Barack Obama, President of the United States -- AMA",
  "numComments": 22719,
  "commentsIncluded": 300,
  "threadComplete": false,
  "markdown": "# I am Barack Obama, President of the United States -- AMA\nr/IAmA · u/PresidentObama · 216183 points · 22719 comments · 2012-08-29\n[…]\n- u/example1 (2025, 2012-08-30): > By the way, if you want to know what I think about this whole reddit experience - NOT BAD!\n  - u/example2 (154, 2012-08-31): He's the president, he knows everything... Like Jesus.\n[…]"
}

Field names stay the same between runs: a value Reddit does not provide is null, not missing. Each failed input gets a free error record with its reason in plain English.

Compared with two of the most used Reddit scrapers

Measured on Apify on October 5, 2026 on real threads; Free plan prices from each Store page and features as described in each Actor's README on October 9, 2026. Both are good tools; other scrapers update often, so these figures are dated.

	This Actor	Alternative A	Alternative B
Recent comments of a 1,650-comment thread	263/263, depth 0 to 12	245/263, depth 9 max	224/263, depth 9 max
Full thread, price	about $1.57	about $2.33	about $3.14
Price per 1,000 comments, Free plan	$1.00	$1.49	$2.00
Price per 1,000 posts, Free plan	$1.50	$1.49	$2.00
Run start (1 GB, the default)	$0.005	none	$0.02
Whole thread as one Markdown record	yes	not described	not described
Built-in "only new since last run"	yes	deduplicate on stable keys yourself	deduplicate on stable keys yourself
Comment search by keyword	yes	not described	yes

On a real thread, comments are nearly all of the bill, which is why the gap grows with discussion size.

How much does it cost to scrape Reddit?

You pay per result. Platform costs are included.

Apify plan	Posts	Comments	User or community profiles
Free	$1.50 / 1,000	$1.00 / 1,000	$1.50 / 1,000
Starter (Bronze)	$1.39 / 1,000	$0.93 / 1,000	$1.39 / 1,000
Scale (Silver)	$1.29 / 1,000	$0.87 / 1,000	$1.29 / 1,000
Business (Gold) and above	$1.19 / 1,000	$0.80 / 1,000	$1.19 / 1,000

Plus the start: $0.005 per GB of run memory ($0.005 at the default 1 GB). The Markdown format is charged the same way (one post, plus one comment per comment in the record). In monitoring mode you only pay for what is new. 1,000 posts with all their comments (about 50,000 comments) come to about $51.50 on the Free plan and $41.20 on Business. You can set a maximum charge per run; the Actor stops at that cap and keeps what it collected.

Use cases

• Brand and product monitoring: posts and comments that name your product, on a schedule, only what is new.
• LLM and AI agent input: whole threads as compact Markdown, with a typed output schema an agent can read first.
• Market and audience research: what a community asks about, complains about and recommends.
• AI and NLP datasets with the reply structure intact, for sentiment analysis, topic modeling or summarization.
• Finding the people who matter in a niche, with their history, karma and activity.
• Academic work that needs a reproducible collection and a record of what could not be retrieved.

Limits

• Reddit lists about 1,000 posts per subreddit sort and about 250 per search. The "Go beyond Reddit's listing cap" option combines sorts and time ranges (3,000 unique posts from one subreddit in our tests), but a subreddit's full history since its creation is not reachable.
• Reddit does not serve deleted comments that have no replies; they are counted in the run summary, not returned.
• Quarantined communities are visible to logged-in accounts only. The Actor reports them and does not log in.
• Strict search checks words, not relevance; quotes around a phrase fix most false matches.

FAQ

Is there a free Reddit API?

Reddit's official Data API requires an approved app, and commercial use is paid. On September 30, 2026, Reddit announced that it stops accepting new API access requests on October 31, 2026 and closes the remaining public access in March 2027, asking apps to move to its Developer Platform. This Actor reads what anyone can see on Reddit without logging in: no app, no key, no account.

Is scraping Reddit legal?

The Actor collects what anyone can see on Reddit without logging in. In hiQ v. LinkedIn, the Ninth Circuit held that scraping publicly accessible pages likely does not violate the US anti-hacking law (CFAA). The results can still contain personal data (usernames, posts) covered by the GDPR and similar laws. Reddit's terms and privacy law apply to how you use the data. Collect what you need for a legitimate purpose, and ask a lawyer if you are unsure.

How do I get only new posts every day?

Turn on "Only new since the last run", then create a schedule in Apify Console (daily or hourly). Add an integration (e-mail, Slack, webhook) to be told when a run returns something.

Which output format should I give an AI agent?

threadMarkdown when it has to read discussions, the default when it has to compute on fields (scores, dates, authors).

How fast is it?

50 posts of a subreddit in 4.7 to 6.0 seconds of run time on Apify, start included. A 1,650-comment thread in under a minute.

Can I get more than 1,000 posts from a subreddit?

Yes. Turn on "Go beyond Reddit's listing cap", and add date filters if you need a precise window.

Why did my run return nothing?

The status message, the free error records and the OUTPUT record give the reason for each input: not found, banned, private, quarantined, nothing in your date window, nothing matching strict search. Such a run ends as Succeeded and costs only the start ($0.005 at the default 1 GB of memory).
