Facebook Comments Scraper ⚡ — Full Comment Threads with Nested Replies

Facebook Comments Scraper extracts public Facebook comments and their replies from any direct Facebook post, video, photo, or share URL. Each row returned by this Facebook Comments Scraper represents one top-level comment, with all replies nested inside the same row under all_replies — giving you the complete conversation thread in a single structured object.

💡 Want to scrape comments from ALL posts on a Facebook profile or page? This Facebook Comments Scraper only accepts direct post URLs. To collect comments and replies from every post published on a profile or page, use the Facebook Posts Scraper — it accepts profile/page URLs directly and returns all posts with full comment and reply data in one run.

🤔 Why Use This Facebook Comments Scraper?

When you need detailed comment threads from specific post URLs, this Facebook Comments Scraper gives you the fastest and most structured path. Unlike flat-row exporters, this Facebook Comments Scraper preserves the natural thread structure: each comment row contains its own replies nested under all_replies, along with full author info, engagement counts, reaction breakdowns, attachments, and timestamps.

⚙️ How This Facebook Comments Scraper Works

1️⃣ Provide input — paste direct Facebook post, video, photo, or share URLs into this Facebook Comments Scraper. 2️⃣ URL resolution — the Facebook Comments Scraper normalizes and validates each URL. 3️⃣ Comment extraction — top-level comments are fetched with full reply threads and engagement data. 4️⃣ Nested output — one dataset row per top-level comment, with all_replies nested inside as a sub-level field. 5️⃣ Billing — you are charged per top-level comment row pushed by this Facebook Comments Scraper.

💡 To scrape comments in bulk from all posts on a profile, use Facebook Posts Scraper instead of this Facebook Comments Scraper.

⚠️ Important — Comment Filter affects how many comments and replies you get: Facebook actively hides a large number of comments and replies when most_relevant or newest filters are selected. If you want to get the maximum number of comments and replies available on a post, always set Comment Ordering to All comments. With other filters, you may receive far fewer results than what is publicly visible on the post.

💡 Tips & Best Practices

• ✅ Replies are nested, not separate rows — this Facebook Comments Scraper stores each comment's replies inside all_replies, keeping the conversation structure intact.
• 🚨 Always use comment_filter: all_comments for maximum results — most_relevant and newest filters cause Facebook to hide a large portion of publicly available comments and replies. When you use these filters, you may get only 1–3 replies for a comment that has 20+ replies publicly visible. The actor will log a warning every time a non-all_comments filter is used.
• 💰 Top-level comments are billed — nested replies in all_replies are fetched and bundled for Extra.
• 📌 Need comments from all posts on a profile? Use Facebook Posts Scraper which accepts a profile URL and returns all posts with their comments — no need to collect individual links before using this Facebook Comments Scraper.
• ⏱️ Combine with Reactions Scraper — pair this Facebook Comments Scraper output with the Reactions Scraper for a complete post engagement + conversation dataset.

❓ Frequently Asked Questions

Q: Can I use a Facebook profile or page URL with this Facebook Comments Scraper? A: No. This Facebook Comments Scraper only accepts direct post URLs. To scrape comments from all posts on a profile or page automatically, use Facebook Posts Scraper.

Q: Where are replies stored in this Facebook Comments Scraper? A: All replies are nested inside the parent comment row under the all_replies field as a structured array. There are no separate reply rows in this Facebook Comments Scraper.
