Top 10 Tools to Find Your Competitors Tech Stack

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.
