In B2B sales prospecting, collecting relevant data is crucial for success. However, this process can be tedious, mainly when you must track information independently. Imagine getting a list of prospects and sifting through each company’s website individually to discover their technology. Not only can it be time-consuming, but it can also lead to inaccurate results since the data can change frequently. This is where tools like Wappalyzer come in. Wappalyzer provides detailed tech stack information on individual websites to help you understand how they operate and what solutions might be a fit for your offering. However, there are alternatives to Wappalyzer that can help you achieve your goals.
This article will discuss some of the top Wappalyzer alternatives for competitor tech stack analysis. Aomni’s website technology checker is one of the top tools for getting accurate tech stack data to improve your B2B sales prospecting efforts.

The Not-So-Good Stuff: Cons of Using Wappalyzer

Wappalyzer isn’t without its drawbacks. Here are the main cons of using the tool for sales prospecting.

Failure to keep the tool current can lead to occasional inaccuracies.

Browser-Specific Adaptations

Each browser requires its own adapted version of the extension, which may lead to compatibility issues or uneven performance across different platforms.

Pricey

Resource Consumption

Running the extension in the background may affect browser performance, particularly on devices with limited resources or when analyzing multiple websites simultaneously.

2. SimilarWeb: Spy on Your Competitors’ Tech Stack

notion image

Key Features
  • Comprehensive technology analysis of websites.
  • Lead generation with technology filters.
  • Competitor analysis and tracking.

3. Rescan: A Simple and Easy Tech Lookup Tool

Rescan is a stripped-down tech lookup tool that gets the job done quickly. This tech profiling tool was previously known as Allora. Still, a rebrand has done a much better job of relating to their target audience of those looking for a WhatRuns alternative that’s more modern and up-to-date.
Main Features of Rescan
  • Tech stack shortcut: Rescan shows a curated list of technology shortcuts for users to jump in quickly. The most popular are eCommerce technologies.
  • Easy to use: Rescan doesn’t come with extra bells and whistles. Instead, it focuses on providing a simple and easy user experience.
  • Works as a website and technology lookup tool: Rescan allows you to check technology trends and market share with great visuals and simultaneously observe a website’s tech stack.

4. Hunter TechLookup: One of the Best Alternatives on the Market

notion image
Hunter TechLookup is one of the best alternatives on the market today. It’s powered by Hunter, an industry-leading email lookup and outreach tool I’ve used for many years, so I was excited when they launched this new profiling tool.
Main Features of Hunter TechLookup
  • Easy to use: Hunter TechLookup uses a sleek and minimalist UI that’s easy to navigate. You can pick your technology from the listed categories and quickly check the websites, categories, and languages.
  • Create your list: Hunter TechLookup lets you build a list you can export and use later. You can narrow down searches to the granular level, tweak the website categories and languages, and use the unique popularity metric to include websites based on their popularity.
  • Free tool: TechLookup allows you to search for technology and gain insights for free, one of its most attractive features. You’ll see the first 5,000 websites for free in your custom list. But with a premium plan, you can go as high as 50,000 websites! I’ve found the free plan to be adequate for most use cases.
  • Part of Hunter ecosystem: Hunter scrapes the internet to find email addresses and guess secret ones with great accuracy. I use Hunter to find prospects’ emails and verify my email list.
Hunter’s scraping DNA has given TechLookup a decisive edge over competitors. The company has also expanded the Hunter suite of products with:
  • CRM integrations
  • Chrome
  • Firefox
  • Google Sheet add-ons

5. W3Techs: A Tech Survey and Research Company

notion image
W3Techs is a web technology survey and research company. They maintain a database of information on the specific technology tools used on websites. This includes:
  • Which CMS is used
  • Which programming languages are used
  • Frontend technology, and so on
W3Techs provides technology information to help website owners make informed decisions about the web technologies they use and to help website developers track trends in web technology usage.
Why Use W3Techs? W3Techs also offers a paid service called W3Techs Insights, which provides, all of which can benefit your sales team, detailed data on:
  • Website technology usage data
  • Tech stack
  • Technology shortcuts

W3Techs: A Comprehensive Tool for In-Depth Website Technology and Usage Analysis

It covers:
  • Website technologies
  • Mobile apps
  • Programming languages
This makes it a more comprehensive resource for research purposes. W3Techs provides data on the percentage of websites using that technology and the top 10 users of technology stacks.
This level of detail regarding technology stacks can be beneficial when understanding how popular a particular technology is and tracking technology trends.
W3Techs is updated more frequently. This is important because the world of website technologies is constantly changing. Without real-time data, you need access to at least the most up-to-date data to make decisions based on technology profiling.

6. Competera: A New Website Shaking Things Up

notion image
A new website on the block is shaking things up in web development. It's called Competera, and it's one of the best alternatives to track live websites. Competera is a technology lookup website that allows you to find out which website builder a site is using and other information about the technology behind it.
Why Use Competera? The answer to this question is simple: Competera is a better version of Builtwith in every single way. Competera offers more comprehensive features, including:
  • Data on all major hosting providers
  • Operating systems
This profiling tool includes everything from web development to marketing to e-commerce, while builtwith.com only offers web development.

Competera: Up-to-date traffic Insights and User-Friendly Website Analysis for Sales and Marketing

Competera includes website traffic data from Alexa and SimilarWeb. This can be helpful if you are trying to gauge the popularity of a particular website and empower your sales and marketing teams. Their team of expert web crawlers constantly analyzes the internet to gather data, so you can be sure that the information in the database is always up-to-date and accurate. This platform is more user-friendly and easier to navigate than builtwith.com.

7. SimilarTech: A Powerful Website Profiling Platform

notion image
SimilarTech is a powerful website profiling platform that provides similar information about website technology. If you’re looking for alternatives, SimilarTech is an excellent option. SimilarTech provides similar website data and insights but offers a few key advantages.
SimilarTech focuses on technology adoption, spanning 30 billion scanned pages per month. Their historical website traffic data goes much further to 2007, so if you're interested in trends, SimilarTech is the better choice. SimilarTech’s user interface is more intuitive and easy to use than BuiltWith. Simply enter a website URL into the search bar and get information about that website in seconds.

8. WhatCMS: Discover What CMS a Website is Using

notion image
WhatCMS.org is a website that allows users to input a URL and get information about the content management system (CMS) with which the site is built. It also provides CMS detection for over 1,000+ different systems. WhatCMS is an excellent tool for developers who want to learn more about how different CMSs work or for businesses who wish to determine which CMS their competitors use.
Either way, WhatCMS can be a valuable resource. WhatCMS is available as a web app and as a downloadable PHP script. The web app is the easiest way to start, but the PHP script offers more features and flexibility.

9. Netcraft: One of the Oldest Names on This List

notion image
Netcraft is one of the oldest names on this list. Over the years, they’ve churned out quality security tools, including a website profiler called “What’s the site running?” Netcraft Site Report uses data mining to find a website’s backend infrastructure and security protocols.
Main Features of Netcraft
  • Detailed report: Netcraft offers one of the most thorough security reports ever. Since their domain is security and compliance, you’ll be hard-pressed to find a better option.
  • IP Geolocation: Many tech lookup tools don’t share IP Geolocation, which can be used to track servers. At the same time, this is a pretty noble decision; Netcraft shares Geolocation.
  • Hosting history: Netcraft tracks the Netblock owner and the hosting records of a website.

10. BuiltWith: A Technology Lookup Service

notion image
BuiltWith is a technology lookup service that lets you see what tools power a competitor's website.
By plugging a website into BuiltWith's search bar, you can discover insights that include:
  • Content management systems and frameworks used to build the site
  • Connected analytics and tracking tools
  • WordPress plugins used to enhance the site
  • Connected enterprise software platforms like Salesforce
  • Registered street addresses for the site's owner
  • Related telephone numbers and company contacts
  • Financial and stock information for the company that owns the site
  • Estimated total corporate technology spend

BuiltWith vs. Similarweb: Deep Tech Stack Insights and Cost-Effective Competitor Analysis

You can also quickly see all associated domains related to the site you search, which is helpful if you're interested in seeing how a competitor handles serving an international audience. And if you're in the tech business yourself, you can use BuiltWith to search for competing technologies and see how many websites use a tool or service.
While Similarweb provides some detail about a competitor’s tech stack, BuiltWith goes deeper. It is also a more cost-effective solution if you’re primarily interested in tech insights.

11. WhatRuns: A Free Chrome Extension

notion image
WhatRuns is a free Google Chrome extension that lets you discover what technologies are used on any website you visit. From server software and analytics tools to programming languages and content management systems, WhatRuns provides a wealth of information at your fingertips.
How to Use WhatRuns Installation:
  • You’ll need to install the WhatRuns extension. To do so, go to the Google Chrome Web Store, search for “WhatRuns,” and click “Add to Chrome.”
  • Exploring a Website: Once installed, visit any website you're curious about. Click the WhatRuns icon on your browser toolbar (it will turn blue when you visit a website).
  • Understanding the Results: A sidebar will appear on the right side of your browser, revealing all the technologies used on the website. These are typically categorized into different sections, and clicking on any technology will give you a more detailed explanation, such as:
    • ‘Frameworks’
    • ‘Programming Languages’
    • ‘CMS’
    • ‘Web Servers’
    • ‘CDN’ and more
WhatRuns also provides a unique feature allowing you to follow websites. If the site updates its technology stack, you will get a notification. This can be especially useful for web developers and tech enthusiasts looking to stay updated with their favorite sites' technology trends.
Remember, while WhatRuns provides an excellent starting point in understanding a website's architecture, it may not capture every detail, as some technologies could be hidden or customized. Nevertheless, it's a handy tool for anyone interested in exploring the world of web technology.

Choosing The Best Tool For Competitor Tech Stack Analysis

Accuracy: The Foundation of Good Website Analysis Tools

Accuracy serves as the foundation of any good website analysis tool. It defeats its purpose if the tool frequently misidentifies technologies or overlooks key components. Whether you’re scouting a competitor’s site or planning a similar project, you need reliable information you can trust. After all, guessing doesn’t help when precision is the goal.

Coverage: The Broader, the Better

Websites today are built with a mix of popular tools, like WordPress or Shopify, and more niche frameworks or custom scripts. A robust tool should cover this entire spectrum. The more technologies it can detect, the more comprehensive your analysis will be. You don’t want to miss out because the tool has a limited library of recognized tech.

Ease of Use: Keep It Simple

Not everyone diving into website tech is a seasoned developer. That’s why ease of use matters. A good tool should have an intuitive interface that works whether you’re a tech pro or a curious user. If you have to spend hours figuring out how the tool works, it’s probably not worth your time.

Real-Time Updates: The Digital World Moves Fast

The digital world evolves fast—new frameworks emerge, plugins get updated, and old tools fade away. A website analysis tool that keeps up with these changes will always be more valuable. The tool risks becoming obsolete without regular updates, leaving you in the dark about the latest technologies.

Depth of Analysis: What Do You Need?

Here’s where you decide what you need. Are you looking for a quick snapshot, like “Oh, this site uses WordPress”? Or do you want a deep dive into server configurations, APIs, and analytics setups? The level of detail you’re after should guide your choice of tool. Some tools give you a surface-level overview, while others are built for serious tech sleuthing.
