In determining the best SaaS tech stack for companies, entrepreneurs, CEOs, CTOs, and IT professionals often get charged with such a task. This decision will, in the end, determine the success of your application.

You could have a terrific concept, marketing strategy, and sales team. However, if your SaaS tech stack does not adapt, evolve, and transform over time, you may find yourself redesigning your entire SaaS web application more than necessary. This strategy almost always ends up being a waste of time, resources, and money.

When you go around SaaS groups and communities, you will see that people always ask what the ideal SaaS technology stack is. A short solution to this question would include language and tools that help you get the job done. However, some languages and technologies will make your developers’ jobs easier and save you money on web development.

Read on to know the best technology stacks for your SaaS Product.

How to Choose the Best SaaS Technology Stack

The following are some of the most common criteria for choosing the best and the finest SaaS tech stack:

●      The prevalent, current language used by your company’s developers;

●      The size of the Software language and platform communities;

●      The tech stack that requires the least amount of training;

●      The critical task of getting developers to match your SaaS tech stack is simple; and

●      The future and long-term possibility of support or assistance.

Furthermore, your SaaS tech stack must allow you to maintain agility, simplify development maintenance, and reduce costs.

Types of Technology Stacks for SaaS Products

For this article, SaaS products’ types of technology stacks will be divided based on two categories: the front-end and the back-end.

For the Front-End

In your product, the user interacts with the front-end — the client-side of your application. Thus, it is critical to do it right the first time, with careful UX writing and UI design.

With that, the following are some of the most often used front-end technologies:


HTML is a markup language used to organize written content, web pages, and other on-site elements.

Moreover, the Cascading Style Sheets, or CSS, is an HTML management toolset that allows you to control and alter views and themes for several pages at once, saving you time from having to create each page separately in HTML.


Javascript allows all of a website’s scripts to do numerous jobs. It allows a website to be “live” because you can view new content without refreshing the page.

Many organizations utilize Bootstrap for CSS and AngularJs for Javascript-based user interfaces when used together. Here are some other alternatives:

●      Backbone.js

●      Coffeescript

●      LessCSS

●      Middleware

●      ReactJS

Furthermore, this includes all web servers, application servers, content management systems, and other tools to host, create, and deliver your product or service to end-users.

Additionally, it connects the backend with the frontend, and JVM languages (Java, Scala, Clojure, etc.), Node.js, or Ruby on Rails get used frequently in this function.

For the Back-End

All of the functions, logic and real programming gears are contained in the back-end or business-facing side of your software. Moreover, it receives the user’s queries and responds to them. Additionally, databases, content production, updating, and much more get handled by the backend.

Python, MongoDB, PostgreSQL, Redis, and other prominent back-end technologies are just a few examples.

Tech Stacks of Popular Companies

For reference, here is a comprehensive list of the tech stacks that prominent companies implement:

●      Airbnb: PHP, Python, JavaScript, Java, Ruby

●      Facebook: PHP, React, Cassandra, Jest

●      Letgo: PHP, Symfony, MySQL, Python

●      Slack: PHP, Python, JavaScript, Java, Go,Ruby, C/C++, Kotlin, Objective-C

●      SpaceX: PHP, Python, JavaScript, Java, Ruby,C/C++

As you can see, Python gets used by practically every company on this list. The majority of them make use of JavaScript and PHP in some form. Please keep in mind that JavaScript can also become frontend JS or a backend Node.js. It is also worth noting that only Slack develops native apps in Objective-C and Kotlin.

Which Tech Stack Should You Use?

In light of the preceding, here is the optimal technology stack for a startup in 2021.


React: React, which was invented by Facebook, made UI creation much  easier. By separating all development pieces into components, attributes, and  states, React made it incredibly simple to start building complex sites.


AWS: AWS is the world’s largest massive cloud, with the highest number  of customers. Although Azure is closing the gap, the majority of people still  utilize AWS. When it comes to cloud services, AWS should be your first  choice.


React-Native: React-Native was, and still is, the most popular cross-platform  development option. React-Native, which Facebook created, makes it easier to  develop mobile apps.


Native (Kotlin for Android  and Swift for IOS): Those that want the finest  performance and the most cutting-edge features should write their apps in  native code, such as Kotlin for Android and Swift for iOS.


Node.js with Express: Node.js is an intriguing concept for building server-side APIs and  answers, and it will be one of the most popular frameworks in 2021. It allows  you to develop APIs in pure JavaScript, including database calls and  sophisticated calculations. Node.js uses Chrome’s V8 engine to run JavaScript  at breakneck speed.

The Express framework simplifies the creation of routes, HTTP  requests, and responses.

PHP with Symfony: PHP is a well-established framework that has weathered the test of  time. PHP, created by Rasmus Lerdorf 26 years ago, has excellent performance,  stability, and flexibility for startups. Your company will benefit from  Symfony’s standard MVC development model and the ability to prototype new  APIs quickly.

Python with Django: Python is a relatively young web programming language. It is,  however, a powerful one with Django. Python gets used by many of the world’s  top software organizations because of its ease of use and speed of  development. Django is a feature-rich web framework that allows developers to  create websites quickly.


While deciding on the optimal startup tech stack for your company may appear difficult initially, it can be easy with research. Ultimately, choosing the proper technology entails selecting the languages, cloud technologies, and frameworks that will assist you in achieving your objectives as rapidly as feasible.
