About BuiltWith (Bulk URLs)

Ever need to know what tech stack a competitor's site is running, or verify a list of client websites? I use this BuiltWith scraper for that. It's my go-to for pulling the technology profiles from a bunch of URLs at once—think CMS platforms, analytics tools, payment processors, and server software. You just feed it your list, and it gets to work. The speed is great; you're not waiting around forever for results, which is perfect when you're researching leads, doing a competitive analysis, or auditing a portfolio. And honestly, for what it does, the cost is really reasonable. It saves me the headache of manual checking or writing my own scripts. If you're in SEO, sales, or development and regularly need to batch-check what websites are built with, this actor makes it straightforward and efficient.

Documentation

BuiltWith (Bulk URLs) Actor

This Apify actor analyzes one or more websites using the BuiltWith API to identify the technologies they use. It's designed for bulk processing and is categorized under Developer Tools, Lead Generation, and SEO Tools.

Important Note: The BuiltWith API does not support URL paths. Provide only the base domain (e.g., https://www.linkedin.com, not https://www.linkedin.com/br/abc).

Key Features

The actor provides three main processing modes:
* Get Technology Profile: Returns the main technology products found on a site.
* Get Technology Profile (Full): Returns both main products and their sub-products for a more detailed breakdown.
* Get Company Profile: Retrieves company information associated with the domain.

How to Use

  1. Input: Provide a list of website URLs to analyze in the actor's input. Use the base domain format.
  2. Select Mode: Choose your desired processing mode (e.g., Get Technology Profile).
  3. Run: Start the actor. The results will be available in the dataset upon completion.

Input & Output

Input: A list of website URLs (e.g., apify.com). The actor will handle the protocol.

Output: The dataset contains structured data (typically in JSON format) based on the selected mode, listing the detected technologies or company profile for each input URL.

Configuration & Performance

Control the actor's speed and avoid rate limits using these key parameters:

  • Maximum Concurrent Requests: Sets how many requests are sent to BuiltWith in parallel.
  • Concurrency Coefficient: Works with the max requests to define a per-minute limit. For example, with a max of 5 and a coefficient of 5, the actor will pause if it reaches 25 requests within a minute for the remainder of that minute.

Warning: Higher concurrency settings increase the chance of being blocked by the target service.

Support & Best Practices

  • Proxy: Always use a high-quality or custom proxy when running this actor against a large number of websites. This is critical to avoid getting blocked.
  • Pacing: Set reasonable concurrency and wait times to mimic human behavior and prevent bans.
  • Issues: For bug reports, please open a new issue and include your Run URL for debugging.
