Reddit Post Comments Scraper

Reddit Post Comments Scraper is a reusable BrowserAct template for extracting a complete structured comment thread from a known public Reddit post. It is designed for post-URL workflows and differs from templates that search Reddit by keyword before collecting posts and comments. The Bot only reads public Reddit pages and does not require login.

What Does BrowserAct Reddit Post Comments Scraper Do?

The Bot validates the Reddit post URL, loads its public comment data, applies the selected comment sort, and returns top-level comments plus nested replies when enabled. It preserves the reply hierarchy with parent IDs and depth, and it marks deleted or removed comments without inventing missing authors.

Extracts complete public comment text and nested replies.

How to Build a New Scraper Bot with Agent Built

Step 1: Describe the Data You Need

Open BrowserAct and start Agent Built from the Home prompt box or from Create -> Build with Agent. Describe the public website, records, reusable inputs, output fields, and result limit.

Start Agent Built

Step 2: Let BrowserAct Build and Test the Bot

BrowserAct explores the live website, determines the navigation and extraction path, and validates the structured result. Add missing constraints in the same build conversation when needed.

Step 3: Run the Bot and Review the Result
