Scrapling vs Agent Browser: A Quantitative Comparison for Web Scraping in 2026

Executive Summary

In this article, I compare two popular web scraping approaches: Scrapling (traditional scraper) and Agent Browser (headless browser automation). Based on real-world testing with 6 data sources and 59 daily articles, here are the key findings:

Introduction

Web scraping has become essential for data aggregation, market research, and competitive analysis. However, the landscape has evolved significantly. Modern websites increasingly use JavaScript rendering, making traditional scrapers less effective.

I tested both approaches on a real-world project: building a daily news aggregator that collects articles from 6 sources. This article presents quantitative data from 30 days of production testing.

Methodology

Test Setup

2. GitHub Trending - Mostly static
3. CSS-Tricks - Static with some JS
4. Smashing Magazine - Static with some JS
5. Medium - Heavy JS rendering
6. Dev.to - Heavy JS rendering

Metrics Measured

• Execution Time: Total time to scrape all sources
• Success Rate: Percentage of successful requests
• Memory Usage: Peak RAM consumption
