Pricing

This Actor uses pay-per-event pricing:

• Run started: charged once when a run starts to cover fixed startup work.
• Comment extracted: charged for each public Facebook comment row saved to the dataset.

Current rates and account-tier discounts are shown on the live Apify Pricing tab. Check that tab before running large jobs.

Tips for best results

• Use public Facebook post URLs that load without being logged in.
• Start with a low maxCommentsPerPost value, review the dataset, then scale scheduled runs.
• Split very large monitoring jobs into smaller batches so one blocked or private post does not delay unrelated posts.
• Keep source post URLs in your downstream database so repeat exports can be deduplicated by commentId and sourcePostUrl.

API usage

Node.js:

import { ApifyClient } from "apify-client";

const client = new ApifyClient({ token: process.env.APIFY_TOKEN });
const run = await client.actor("fetch_cat/facebook-comments-scraper").call({
  startUrls: [
    { url: "https://www.facebook.com/humansofnewyork/posts/pfbid0BbKbkisExKGSKuhee9a7i86RwRuMKFC8NSkKStB7CsM3uXJuAAfZLrkcJMXxhH4Yl" }
  ],
  maxCommentsPerPost: 20
});
console.log(run.defaultDatasetId);

Python:

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("fetch_cat/facebook-comments-scraper").call(run_input={
    "startUrls": [
        {"url": "https://www.facebook.com/humansofnewyork/posts/pfbid0BbKbkisExKGSKuhee9a7i86RwRuMKFC8NSkKStB7CsM3uXJuAAfZLrkcJMXxhH4Yl"}
    ],
    "maxCommentsPerPost": 20,
})
print(run["defaultDatasetId"])

Limits and caveats

• The Actor runs against public, visible Facebook post pages. It does not log in, bypass privacy settings, or return private comments.
• Facebook can hide, reorder, or limit comments in public views; the dataset reflects what was visible during the run.
• Some optional fields, especially author URLs and comment permalinks, are only saved when Facebook exposes them publicly.
• Relative dates are captured as displayed by Facebook. Use scrapedAt with relativeDate for freshness analysis.
• Process only public data you are allowed to access, and follow applicable terms and laws.

FAQ

What data can I export with Facebook Comments Scraper?

You can export visible public comment text, author names, source post URLs, relative dates, likes when shown, reply labels when shown, raw visible text, and scrape timestamps.

Can I run Facebook Comments Scraper through an API, schedule, or MCP client?

Yes. You can call the Actor through the Apify API, schedule repeat monitoring runs, connect webhooks, or use the Apify MCP Server from compatible AI tools.

How much does it cost to use Facebook Comments Scraper?

The Actor charges a small run-start event and a per-comment event for each saved dataset row. Check the live Apify Pricing tab for current tier prices before running large jobs.

How do I export Facebook comments data to CSV or Excel?

Run the Actor with public post URLs, open the default dataset, and choose CSV, Excel, JSON, XML, RSS, or API export from Apify.

Why are some author URLs or comment links empty?

Facebook does not always expose profile links or comment permalinks in logged-out public views. The Actor leaves unavailable optional fields empty instead of guessing.

Can it scrape private groups or comments behind login?

No. The first version is limited to visible public post comments and does not use user accounts or private permissions.
