Best BuiltWith Alternatives in 2025

BuiltWith is a popular tool for website technology analysis that uncovers the tech stack behind any website. As a result, businesses, marketers, and developers rely on it for competitor research, market trends, and lead generation. 

However, BuiltWith isn’t perfect: its high pricing, limited free plan, and data depth issues often push people to seek alternatives.

If you’re looking for a BuiltWith alternative, several other tools offer similar or even better functionality—some for free and others with paid options. 

If you need a full-scale technology tracker or a niche tool for specific insights, this guide explores the top BuiltWith alternatives for 2025: 

Why Look for a BuiltWith Alternative?

Before exploring alternatives, you must understand BuiltWith’s strengths and limitations.Let’s break them down: 

BuiltWith Capabilities

1. Website Technology Stacks

BuiltWith offers detailed identification of a website’s tech stack, which includes a broad range of tools and technologies that power a site. This covers the Content Management System, hosting providers, and the programming frameworks. 

Additionally, it identifies analytics tools, ad networks, and third-party plugins or integrations, such as payment processors, live chat services, and marketing automation tools.

2. Competitor Analysis

BuiltWith is especially valuable for competitive intelligence. It tracks the technologies competitors are using, and provides a clear view of what’s trending in a particular industry or market segment. 

BuiltWith’s analysis also shows adoption trends thatidentify whether technology is gaining traction within their industry. 

3. Lead Generation

BuiltWith also excels in lead generation by helping businesses segment potential clients based on their technology stack. 

For example, a company offering a new plugin or service for a specific platform like Shopify can use BuiltWith to identify all Shopify stores and reach out to them directly, maximizing the chances of converting those leads. 

The Limitations of BuiltWith

Despite its powerful features, many users look for an alternative to BuiltWith due to:

1. Pricing

One of the main deterrents for many users is BuiltWith’s premium pricing, which can cost hundreds of dollars per month depending on the plan you select. Although BuiltWith’s advanced features offer valuable insights, these features come at a significant financial cost. 

This pricing structure can be prohibitive, especially for small businesses or startups with limited marketing budgets. For companies that don’t need the full suite of advanced features, the cost may outweigh the benefits. 

2. Data Depth Issues

Another limitation of BuiltWith is that, while it offers a broad array of technology detection, it may not always provide comprehensive insights into certain technology stacks. Some niche tools or newly emerging technologies may not be fully detected or may be listed only in broad categories. 

Additionally, some data points might be missing or outdated, which can impact the overall accuracy and reliability of the analysis. These limitations can be frustrating for conducting detailed research or target emerging trends in the tech landscape.

3. Ease of Use

Despite being a powerful tool, BuiltWith’s interface is often described as complex and unintuitive compared to some of its competitors. Although the tool is packed with features, the learning curve can be steep—especially for users who aren’t familiar with the technical aspects of website technology. 

In contrast, many BuiltWith alternatives are designed with simpler, more intuitive interfaces, allowing users to quickly access and understand their website technology insights without extensive training.

4. Limited Free Plan

While BuiltWith does offer a free plan, the data it provides can be highly limited. Users on the free plan are restricted to basic insights—often seeing a snapshot of a website’s technology stack without the depth required for strategic decision-making. 

The limited scope of the free version makes it less effective for anyone who requires in-depth analysis or detailed competitor tracking. For businesses wanting to go beyond the surface-level data and gain actionable insights, the free plan likely falls short. 

How to Choose the Best BuiltWith Alternative

Not all BuiltWith alternatives offer the same features. Before picking one, consider these key factors:

1. Full Scale vs. Specific Use Case

Do you need a complete website technology analysis, or are you looking for something specific, such as:

• Security-focused scanning (e.g., Netcraft)
• Competitor research for eCommerce (e.g., Koala Inspector)
• Lead generation through technology tracking (e.g., SimilarTech)

2. Pricing (Free vs. Paid Options)

If you need a BuiltWith com alternative, tools like WhatRuns or Wappalyzer provide free insights. However, paid tools offer more advanced tracking, historical data, and automation features.

3. Integration with Other Tools

Some alternatives integrate with CRM systems, sales tools, and marketing platforms for better workflow automation. If you need seamless integration, prioritize tools with API access.

4. Ease of Use & Data Accuracy

A user-friendly interface is critical, especially if you’re not a technical user. Data accuracy varies between tools—some detect more in-depth details than others.

Now, let’s explore the top BuiltWith alternatives available in 2025:
