How to Scrape Infinite Scroll Pages with RTILA X

Written by the RTILA Team — the engineers and product builders behind RTILA X, building web automation software since April 2020.

Infinite scroll pages are everywhere. Social feeds, e‑commerce product listings, news sites—they all use the same technique: load more content as you scroll down. For anyone trying to extract data from these pages, the traditional approach of “open a URL, grab the HTML, and move to the next page” falls apart. There’s no “next page” button, no page number in the URL, and the content only appears when you physically (or virtually) scroll. If you’ve ever wondered how to scrape infinite scroll pages without breaking your workflow, RTILA X gives you three built‑in, battle‑tested ways to do it—no custom scripts required.

In our experience building RTILA X since 2020, we’ve seen infinite scroll break more automations than almost any other pattern. So we built the infinite_scroll command specifically for this challenge. It works alongside the Dataset Builder to capture every item as it loads, and when the page uses an API under the hood, the Network API Interception can grab the data directly, skipping the scroll entirely. In this guide, we’ll walk through each method, show you how to configure the steadiest possible scrolling, and share a real‑world example we tested on a social media feed.

How to scrape infinite scroll pages with the infinite_scroll command

The infinite_scroll command is the backbone of RTILA X’s infinite scroll scraper capabilities. It does exactly what it sounds like: it scrolls a page or a specific container until no new content appears, or until it hits a limit you set. You drop it anywhere in your project flow, and it handles the rest.

The command reads the page’s scrollable area—whether it’s the whole window or a nested div—and uses a series of human‑like mouse movements to trigger content loading. This isn’t a simple window.scrollBy(0, 1000); it’s a full simulation that respects the browser environment. Behind the scenes, the stealth engine introduced in version 8.3.0 applies cubic Bézier curves to the mouse path, adds micro‑variance, and even performs an overshoot‑and‑correct gesture to mimic a real hand. That keeps anti‑bot systems from flagging the activity.

Here’s how you configure it:

• max_scrolls – the maximum number of scroll attempts before stopping (useful for long feeds).
• scroll_delay – the pause between scrolls, in milliseconds. A slightly random delay helps avoid triggering rate limits.
• do block – a block of actions that run after each successful scroll. You can extract data, take a screenshot, or run a custom snippet.

For stubborn SPAs that don’t respond to smooth scrolling, RTILA X’s infinite_scroll command automatically falls back to a physical mouse wheel simulation. That means it sends actual wheel events at the OS level, not just JavaScript dispatches. Combined with the jiggle technique—a tiny shake of the scroll position before the main movement—this often unblocks sites that detect headless browsers.

A crucial reliability feature is the 3‑failure detection. If three consecutive scrolls produce no new content (measured by comparing the number of DOM items before and after), the command stops. You won’t waste time scrolling an empty feed, and you can later use Checkpoint & Resume to pick up where you left off.

A quick example: scraping a social media feed

When we tested this on a real social media feed, we built a project that opens the page, closes any consent pop‑ups with handleConsent, and then runs the infinite_scroll command. Inside the do block, we used the extract_data command with a Dataset Builder configured to grab the post text, author name, and timestamp.

goto: https://example-social.com/feed
infinite_scroll:
  max_scrolls: 25
  scroll_delay: 1200
  do:
    - extract_data:
        item_selector: ".post"
        properties:
          - text: ".post-text"
          - text: ".post-author"
          - text: ".post-time"
        deduplicate_by: ".post-link"

The Dataset Builder (check out our full guide on using it) automatically deduplicated items by the unique post link, so we never collected the same post twice. When the feed stopped loading after the 3‑failure detection, the project saved the dataset and moved on. The whole automation ran in the background, with the app window closed, thanks to the Task Scheduler and background execution.

How to scrape infinite scroll pages that load data via APIs (Network Interception)

Not all infinite scroll pages render content in the DOM step by step. Many modern applications fetch JSON data from a backend API as you scroll, then render the posts client‑side. In those cases, scrolling itself is just a visual trigger; the real data is already passing through the network. RTILA X can intercept those API responses directly, turning what looks like an infinite scroll problem into a simple JSON extraction job.

This is where the Network API Interception feature shines. With the http_request or run_script command, you can listen for specific API calls and capture their payloads. For example, if the feed loads posts from /api/v1/feed?cursor=…, you can use interceptApiData to catch every response and store the data in a variable.

run_script:
  code: |
    const data = await interceptApiData({
      urlPattern: '/api/v1/feed',
      method: 'GET',
      captureCount: 50
    });
    // data is an array of JSON responses
    saveData(data, 'feed_data.json');

This approach is faster and more reliable than scrolling because it bypasses the DOM entirely. You can also pair it with the crawl_links command if the API uses pagination with cursor tokens—a technique we cover in depth in our pagination guide. The data lands in your dataset with zero extra rendering time.

For pages that use GraphQL subscriptions or WebSocket feeds, the waitForApiResponse helper inside run_script can also capture those messages. Our Network Interception deep‑dive walks through setup for different API styles.

Using the autoScroll helper in run_script for total control

Sometimes you need more granular control than the infinite_scroll command provides. Maybe the page uses a non‑standard scroll container, or the infinite scroll relies on a complex intersection observer with a specific threshold. The autoScroll helper inside run_script lets you script the scrolling behavior yourself, while still using RTILA X’s humanoid motion engine.

autoScroll accepts the same parameters as infinite_scroll—maxScrolls, delay, and scrollStep—but you can also specify a custom container element or control the direction. Here’s how you might use it to scrape a horizontally scrolling “infinite” gallery:

run_script:
  code: |
    const container = await page.$('.gallery');
    await autoScroll(container, {
      maxScrolls: 30,
      delay: 800,
      scrollStep: 600,
      axis: 'x'
    });

The helper still applies the jiggle technique and the physical mouse wheel fallback, so you don’t lose the anti‑detection layer. In our testing, we’ve used this to handle a news site that loaded articles only when the footer came into view—a scenario that infinite_scroll couldn’t catch because the scrollable area was a tiny hidden div. With autoScroll, we targeted that div directly and extracted a full year of articles.

The autoScroll helper is part of the run_script command’s library of built‑in functions, which also includes handleConsent and waitForNetworkIdle. You can combine them to build a resilient auto‑scroll scraping workflow that works even on the most peculiar front‑end frameworks.

Building a complete infinite scroll scraper project

Now, let’s put everything together. Suppose you want to scrape a tech blog’s infinite-scrolling archive page, extract all article titles, and store them in a structured format. You’ll need to handle the initial load, scroll through the content, capture the data, and stop gracefully.

Here’s a project that does exactly that, using the infinite_scroll command, the Dataset Builder, and the Checkpoint & Resume system for reliability.

Step 1: Open the page and handle any pop‑ups
Use the goto command followed by handleConsent to clear cookie banners.

Step 2: Set up the Dataset Builder
Define the item selector for each article card and list the properties you want to extract. Enable deduplication by the article’s URL so you don’t collect duplicates when the scroll loads more of the same content.

Step 3: Run the infinite_scroll command with a do block
Inside the do block, call extract_data to pull the new items into your dataset. Set max_scrolls to something reasonable, like 50, and scroll_delay to 1500 ms to mimic a slow reader.

Step 4: Save the dataset and set a checkpoint
After the scroll finishes, export the dataset to CSV or JSON, and save a checkpoint. If the automation ever gets interrupted, Checkpoint & Resume will restart from the last successful scroll, not from the top.

This entire project runs in the background on your desktop, even when the RTILA X window is closed. The Task Scheduler can repeat it weekly, or you can trigger it manually. The free Community plan includes unlimited runs, so you can test this on your own target sites without spending a dime.

Conclusion

Learning how to scrape infinite scroll pages doesn’t have to mean writing fragile custom scripts that break every time a site changes its layout. RTILA X gives you a trio of production‑ready tools: the infinite_scroll command for straightforward DOM‑based feeds, the autoScroll helper for edge cases, and Network API Interception for when the data is already flowing through the wire. Each method respects the page’s behavior, uses human‑like mouse patterns, and stops intelligently when no new content appears.

We’ve been refining these features since our first GitHub release in April 2020, and the latest version 8.3.x incorporates feedback from thousands of automations running on real sites every day.

FAQ

What is the infinite_scroll command in RTILA X?

The infinite_scroll command is a built‑in automation step that automatically scrolls a webpage or a specific container until no new content appears, or until a defined limit is reached. It includes human‑like mouse movement, configurable delays, and a 3‑failure detection to stop when the page is no longer loading data. You can run data extraction actions inside its do block after every successful scroll.

How does RTILA X handle infinite scroll pages that don’t use standard scrolling?

For pages that rely on non‑standard scroll containers or complex intersection observers, RTILA X provides the autoScroll helper inside the run_script command. This helper lets you target a specific element and control the scroll axis, step size, and delay while still using the same human‑like mouse simulation. For API‑driven feeds, the Network API Interception feature can capture the JSON responses directly, bypassing the scrolling entirely.

Can I scrape infinite scroll pages without loading the page in a browser?

Yes, if the page loads data through API calls. RTILA X’s Network API Interception can capture those API responses in real time, so you never need to scroll. You can also use the http_request command to fetch paginated API endpoints directly. However, if the content is rendered only in the DOM after scrolling, you’ll need the infinite_scroll command or autoScroll helper to trigger the loading.
