Reddit Comment Scraper

Reddit Comment Scraper collects public comments from Reddit posts and turns them into structured data for sentiment analysis, market research, and content monitoring. Provide post IDs or URLs, run the Actor, and export comment text, author, score, reply depth, and post metadata to JSON, CSV, Excel, or your preferred integration. Use it to analyze community sentiment, monitor brand mentions, and build comment datasets — no Reddit account required. Pricing starts at $3.00 per 1,000 comments, with post metadata included at no extra charge.

What can you automate with Reddit Comment Scraper?

• Collect full comment threads — pull public comments and nested replies from any Reddit post, with parentId and depth preserved so you can rebuild the conversation.
• Analyze sentiment and product feedback — export comment text, scores, and timestamps to see what communities praise or criticize.
• Monitor brand and topic mentions — schedule recurring runs on the same posts and watch how discussions evolve.
• Build research and training datasets — gather structured comment corpora for analytics, journalism, or model work.
• Sort and cap each thread — choose Best, Top, New, Controversial, Old, Q&A, or Live, and limit comments per post.
• Feed downstream workflows — send results to Google Sheets, a webhook, or your own API pipeline after each run.

Brand and reputation teams	Monitor mention threads and high-score replies without watching Reddit all day.
Content and social teams	Study which comments resonate and how original posters respond.
Data and research teams	Build structured comment datasets for sentiment analysis or model training.

What data can you collect from Reddit?

Data group	Example fields	How it helps
Comment content	body, id, name, createdAt, editedAt	Read the text and order comments in time.
Author and role	author, isSubmitter, distinguished	See who wrote it and whether they are the original poster or a moderator.
Thread structure	parentId, depth, postId	Rebuild reply trees and keep comments attached to the right post.
Engagement	score, ups, gilded, controversiality	Rank comments by traction and controversy.
Post context	postTitle, postUrl, subreddit, subredditNamePrefixed	Know which community and thread each comment came from — included at no extra charge.
Links and state	permalink, fullUrl, stickied, locked, archived, collapsed	Open the comment on Reddit and filter locked or archived threads.

Fields such as editedAt, distinguished, and gilded are only populated when Reddit provides a value. The Actor collects publicly visible comments only.

How to use Reddit Comment Scraper

1. Open the Reddit Comment Scraper on Apify.
2. Enter Reddit post IDs or URLs in searchQueries — for example 1vcvjb9 or https://www.reddit.com/r/AI_Agents/comments/1vcvjb9/.
3. Set maxComments per post (prefill 100; 0 means unlimited) and choose a sortBy order.
4. Run the Actor — it collects public comments from each post you provided.
5. Export the dataset or connect it to your workflow.

{
    "searchQueries": [
        "1vcvjb9"
    ],
    "maxComments": 100,
    "sortBy": "confidence",
    "proxyConfiguration": {
        "useApifyProxy": true,
        "apifyProxyGroups": ["RESIDENTIAL"]
    }
}

Example workflow

Monitor sentiment on a product-launch thread

1. Paste the launch-post URL or ID into searchQueries and set sortBy to top so high-score comments come first.
2. Keep maxComments at 100 for a weekly snapshot, or 0 when you need the full thread.
3. After each run, send new records to Google Sheets or a Slack channel through a webhook.
4. Deduplicate user-side against the stable comment id so you only review comments that appeared since the last run.

The Actor does not filter, score sentiment, or merge runs for you — those steps happen in your own workflow.

Automate and integrate your results

• Schedules — Reddit threads grow quickly. Run hourly or daily on fast-moving posts, and weekly on evergreen discussions. Create a separate scheduled task per post or campaign so each job keeps its own searchQueries and dataset.
• Webhooks — Enable a webhook on run completion to push fresh comments into Google Sheets, Slack, a CRM, or a database.
• Exports and API — Download results as JSON, CSV, Excel, or HTML from the Apify Console, or call the Actor from the API. One cURL example:

curl "https://api.apify.com/v2/acts/scraptivo~reddit-comment-scraper/runs?token=YOUR-APIFY-TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "searchQueries": ["1vcvjb9"],
    "maxComments": 100,
    "sortBy": "confidence",
    "proxyConfiguration": {
      "useApifyProxy": true,
      "apifyProxyGroups": ["RESIDENTIAL"]
    }
  }'

• Deduplication — Within a single run, the same post supplied in searchQueries, postIds, and startUrls is collected once. Across runs, the Actor appends every comment again. Use id as the stable key when merging results.

Input reference

Field	Type	Required	Default	What it controls
searchQueries	Array of strings	No*	—	Reddit post IDs or post URLs (e.g. 1vcvjb9 or https://www.reddit.com/r/AI_Agents/comments/1vcvjb9/). Preferred input — both formats are resolved automatically.
postIds	Array of strings	No*	—	Bare Reddit post IDs only (e.g. 1vcvjb9). Post URLs are built automatically.
startUrls	Array of URLs	No*	—	Full Reddit post URLs, including redd.it short links.
maxComments	Integer	No	0	Maximum comments per post (0 = unlimited). Prefill is 100. Three posts with maxComments: 10 return up to 30 comments.
maxItems	Integer	No	0	Alias for maxComments (per post). Used only when maxComments is omitted.
sortBy	String	No	confidence	Comment order: confidence (Best), top, new, controversial, old, qa, live.
proxyConfiguration	Proxy object	No	Apify proxy, RESIDENTIAL	Proxy settings. Residential proxies are recommended because datacenter IPs are often blocked.

* Provide at least one of searchQueries, postIds, or startUrls. You can combine them; duplicate post IDs are ignored within the run.

What is the difference between searchQueries, postIds, and startUrls?

All three point at the same thing: a Reddit post. searchQueries accepts both bare IDs and full URLs. postIds accepts IDs only. startUrls accepts full URLs, including https://redd.it/1vcvjb9. Use whichever format you already have.

How do maxComments and maxItems work?

maxComments is a per-post cap, not a global run total. 0 means unlimited comments on each post. maxItems is an alias for agent compatibility and is applied only when maxComments is omitted from the input.

Output example

Each dataset item is one comment. Post title, URL, and subreddit are included on every record at no extra charge:

{
    "id": "l8c2m3",
    "name": "t1_l8c2m3",
    "author": "reddit_user_123",
    "body": "This is a really underrated workflow. I've been using agents like this for weeks and the difference is night and day.",
    "score": 214,
    "ups": 214,
    "depth": 0,
    "parentId": "t3_1vcvjb9",
    "postId": "1vcvjb9",
    "postTitle": "I think people seriously underestimate how easy...",
    "postUrl": "https://www.reddit.com/r/AI_Agents/comments/1vcvjb9/i_think_people_seriously_underestimate_how_easy/",
    "subreddit": "AI_Agents",
    "subredditNamePrefixed": "r/AI_Agents",
    "createdAt": "2026-08-07T14:32:10+00:00",
    "editedAt": null,
    "permalink": "/r/AI_Agents/comments/1vcvjb9/i_think_people_seriously_underestimate_how_easy/l8c2m3/",
    "fullUrl": "https://www.reddit.com/r/AI_Agents/comments/1vcvjb9/i_think_people_seriously_underestimate_how_easy/l8c2m3/",
    "isSubmitter": false,
    "stickied": false,
    "distinguished": "",
    "gilded": 0
}

How much does it cost to scrape Reddit?

The Actor uses pay-per-event pricing with two chargeable events:

• $3.00 / 1,000 comments — a dataset-item event for every comment pushed to the dataset ($0.003 per comment).
• $0.00005 per run — an Actor-start event charged once when the run begins.

Post metadata (postTitle, postUrl, subreddit, and related fields) is included with each comment at no extra charge. A 100-comment snapshot costs about $0.30; 1,000 comments cost $3.00; 10,000 comments cost $30.00, plus the $0.00005 start fee. Paid Apify plans discount the per-1,000 comment rate to $2.90 (Bronze), $2.80 (Silver), and $2.70 (Gold). Compute units consumed are deducted from your Apify plan, and residential proxy traffic is billed separately by Apify according to your plan. When your event spending limit is reached, the run stops — you will see that status in the run log.

Reliability and responsible use

• Proxy requirement — The Actor defaults to the Apify proxy with the RESIDENTIAL group. Residential proxies are recommended because datacenter IPs are often blocked by Reddit.
• Public comments only — The Actor collects publicly visible comments. No Reddit account is required.
• Per-post limits — maxComments applies independently to each post. Nested replies are included and tagged with depth and parentId.
• Conditional fields — editedAt is null when a comment was never edited; distinguished is empty when the author is not a moderator or admin; other flags follow what Reddit exposes.
• Responsible use — Only use the data in ways that comply with Reddit's terms of service and applicable law.

Frequently asked questions

Can I scrape comments from Reddit without an account?

Yes. Paste public post IDs or URLs and run the Actor — no Reddit login is required. Only publicly visible comments are collected.

Can I scrape nested replies and full threads?

Yes. Set maxComments to 0 to collect the full public thread on each post. Replies keep parentId and depth, so you can reconstruct the conversation tree instead of a flat list of top-level comments.

Can I schedule Reddit Comment Scraper to run automatically?

Yes. Open the Scheduler tab in Apify Console and set a recurring schedule. Hourly or daily suits fast-moving threads; weekly suits evergreen posts. Create a separate schedule per post or campaign so each job has its own searchQueries.

What counts as one result?

Each comment pushed to the dataset is one dataset-item event at $3.00 per 1,000 comments (Bronze $2.90, Silver $2.80, Gold $2.70). Post metadata on that comment is not billed separately. The Actor-start event is $0.00005 per run.

What is the difference between searchQueries, postIds, and startUrls?

searchQueries accepts post IDs or URLs. postIds accepts bare IDs only. startUrls accepts full post URLs, including redd.it links. Provide at least one source; if none contain a recognizable post, the run fails with "No valid Reddit posts found." A subreddit URL is not a post URL.

How do I avoid duplicate records?

The Actor appends comments on every run and does not deduplicate across runs. Use the stable id field as the key when merging a fresh run into existing data. Within one run, the same post listed in more than one input field is collected once. Setting maxComments caps the size of each post in a run.

Do I need a proxy?

Residential proxies are recommended because datacenter IPs are often blocked by Reddit. The default input already uses the Apify RESIDENTIAL group. If a run returns no comments, confirm that proxy configuration is still set to residential.
