The fintech industry is evolving and growing at a rapid pace with many fintech startups launching and becoming unicorns in recent times. Choosing the right tech stack can be a challenging process while developing your Fintech application, and thus to make that process easier for you, we have compiled a list of the best 15+ tech stacks that you can use and launch your Fintech startup. 

How To Choose A Tech Stack For Fintech?

Choosing the right fintech tech stack depends on several factors such as the project size, security requirements, budget, and more. Let’s discuss the top 3 factors that you should consider while developing your fintech app. 

Security Standards

If your fintech startup involves storing the personal data of your users such as their information, banking details, and more, then you should choose a tech stack that is cyber secure such as Angular to protect your data. 

Costing

Your budget also plays a major role in deciding which tech stack to consider. A tech stack with advanced features such as AI, ML, etc will cost more. Moreover, you should also consider developing your app using cross-app development platforms such as Flutter, FlutterFlow, React Native, and more instead of native app development. 

Scalability 

If the market size that you are planning to tap is massive, your software must have easy-to-scale capabilities. It should support a growing user base and support high-volume transaction processing. 

What All Are Included In A Tech Stack?

The tech stack comprises the following parts:

Front-end (Client Side)

Used to create user interfaces, the front-end tech stack comprises of frameworks such as Angular, React, Next.js, and more. It’s responsible for the look and feel that your software will have and the way your customers will view it. 

Back-end (Server Side)

This part of the tech stack is not visible to the users and it consists of server-side processing and data management, The Backend usually comprises Java, Python, Ruby, and more. 

Moreover, a backend comprises a server, a database, and an application logic. 

APIs And Middleware

  • APIs allow your software to interact with other software, for example, if there is a login option on your software, then you can integrate a Google login API through which users can directly login using their Gmail. 
  • Middleware software like Express.js helps in connecting the front-end and back-end handling data requests, authentication, and more. 

More such tech stacks can be used while developing a fintech application which we will be discussing below:
