Choosing a tech stack is a crucial step in building any company since it forms the foundation on which you'll scale. A tech stack refers to the collection of tools a company uses to run its application, ranging from the programming language to third-party tools like payment processors. Ideally, you should choose a tech stack that can easily adapt to new technology, features, and customer needs.
Accessing your competitor's tech stack provides insight into their technical capabilities and potential blockers. Additionally, if you're building a solution that competes with a particular tool, many of these websites offer lead lists. Instead of searching by a competitor, you can look up a tool and use the list to reach out to potential customers. Knowing your competitor's tech stack will enable you to develop a compelling pitch highlighting how your tool can fit in and what sets your product apart from their current solution.
Let’s take a look at 10 websites and browser extensions you can use to find your competitor's tech stack.
Wappalyzer is a competitor analysis tool with a technology look-up feature. It allows for 50 free lookups per month and is easy to use. Simply, input your competitor's URL, or upload a list of websites to analyze multiple competitors at once. The tool generates a tech stack that is organized into categories, such as Issue Tracker, Payment Processors, Security, and Analytics. Clicking on each tool provides pricing, a brief explanation of its use case, and a link to the website.
With a paid account, you can generate a lead list of other companies based on the technologies they use. Adding details such as keywords, domains, and company information will tailor the list further. Wappalyzer also allows you to set up notifications to know whenever a company adds or removes a tool.
