A lot of factors are considered before and during a SaaS development.
One important decision you will have to make is selecting the right technology stack to use for your project. This decision is not just a minor detail; it plays a big role in many parts of how your SaaS will work in the future.
The technology stack you choose will affect the performance and efficiency of your software in various ways.
Why does this matter so much?
Well, the software development industry is not just vast but also incredibly competitive. The market is expected to hit $698.80 billion this year with projections climbing to $858.10 billion by 2028. The SaaS sector, in particular, is seeing even more impressive growth, with estimates predicting it will reach around $1,251.35 billion by 2034, according to the recent Precedence Research.
Given this competitiveness, it’s essential to deliver top-class SaaS applications. What you choose as your tech stack plays a major role in this. It affects everything from your app’s responsiveness to its user-friendliness and data management.
The programming languages and frameworks will dictate how well your app performs, while the database management system (DBMS) impacts data efficiency.
Keeping this in mind, you may begin to wonder what a tech stack is and what SaaS tech stack you need, to launch your software service to the forefront of 2024. This blog will help you answer these questions.
What is a SaaS Tech Stack?
We all know a stack as just a collection of things piled together in everyday language.
However, the term “stack” means something else in technology – it refers to a set of tools and technologies that work together. It includes everything from programming languages to frameworks and libraries. Choosing the right combination is important as it impacts how well your software is built and maintained.
A well-chosen SaaS stack helps ensure your software functions smoothly and remains dependable over time. Getting it right can prevent many future issues.
Key components of the SaaS tech stack
Let’s face the facts. Before the days of widespread SaaS products, SaaS technology stacks were simpler. Common setups included LAMP (Linux, Apache, MySQL, PHP) for PHP-based web apps and WAMP for Windows users.
Today, there are many tools available for product teams and engineers to build and maintain products.
So many that, newbies in the tech space are usually confused as to which tool to choose. Early-stage companies may usually choose low-cost, flexible options. This way, they can always change later.
Others might pick scalable technology to meet enterprise demands.
Here’s a breakdown of the basic key components of a SaaS tech stack:
Front-end
Let’s begin with the front-end technologies. The front end is the part you see, touch, and interact with on a website or app. It includes everything you see and use on a website or app, such as buttons, images, text, and navigation menus.
- Languages: HTML, CSS, JavaScript
- Frameworks: React, Angular, Vue.js
Purpose:
- HTML provides the basic framework for websites. It’s the skeleton of the web pages. Consider headings, paragraphs, links, images, and other types of content. It basically tells the web browser how to display the content of a webpage.
- CSS styles everything. It controls the appearance of HTML elements, including their colors, fonts, sizes, spacing, and positioning.
- JavaScript brings life, creating animations and special effects. JavaScript checks if a form is filled out correctly before it’s submitted.
Backend
The backend is the part of a website or app we (users) don’t see. There is a joke about frontend guys getting more credit than they deserve because we can see and admire beautiful webpages whereas the backend guy does so much to keep a webpage running but they hardly get any praise. You get the drift.
The back end in tech is everything that happens behind the scenes of a website or app. It includes:
- Servers: Computers that provide data to your device.
- Databases: Where information is stored and managed.
- Application Logic: Code that processes data and handles tasks like logging in or processing payments.
Together, they make sure the website or app works properly by storing data, processing user requests, and sending information to the front end for you to see and interact with.
- Languages: Python, Ruby, Node.js, Java
- Frameworks: Django, Ruby on Rails, Express
Purpose:
- Processes requests from users.
- Manages the business logic.
- Deals with the database.
- Ensures everything on the front end works properly.
Databases
Database stores and organizes information for apps and websites. Websites and apps can keep track of data, including user accounts, posts, or products to find and use this information quickly when needed.
Types:
- SQL Databases: PostgreSQL, MySQL
- NoSQL Databases: MongoDB, Redis
Purpose:
- Store Information: Keeps data in one place for easy access.
- Organize Data: Arranges information so it can be quickly found.
- Manage Data: Allows for updates, deletions, and additions to the data.
Retrieve Information: Provides quick access to the data when needed.
Key Considerations While Choosing Your SaaS Tech Stack
1. Feature Deployment
For a smooth process, you can use tools for Continuous Delivery, which allow you to introduce updates with minimal human effort and fewer errors. Set up systems that automatically adjust resources and handle administrative tasks, to improve efficiency and reduce the need for manual intervention.
2. Evaluate Technology Longevity
Check if the technology you choose has a stable future. Ensure that the technology has a reliable track record and a clear path for future development. If it doesn’t, you might need to switch languages or frameworks later on when support ends.
3. Consider IT Outsourcing Consultants
Consider hiring IT outsourcing consultants to help analyze your project needs and select the best solution for you. These experts with their experience, will provide valuable insights into the best technologies for you.
Front End Tech Stack
Selecting the right front-end tech stack is really important for making a software look good and work well. Let’s go through some popular options when it comes to front end technologies:
HTML (HyperText Markup Language)
- Purpose: HTML is what makes the basic structure of web pages. It tells the browser where to place headings, paragraphs, images, links, and other content.
- Considerations: The latest version, HTML5, brings in new features like better support for multimedia and improved performance. It’s quite handy.
CSS (Cascading Style Sheets)
- Purpose: CSS is used to style web pages. It controls how things look, such as colors, fonts, spacing, and making sure the design works on different devices.
- Considerations: There are modern tools like Sass and Less that can make writing CSS easier and more powerful. They are worth looking into.
JavaScript
- Purpose: JavaScript adds interactivity to web pages. It makes things happen when you click buttons or scroll the page, making the user experience more engaging.
- Considerations: ES6+ (ECMAScript 6 and beyond) introduces new features that make JavaScript more powerful and easier to work with. These updates are helpful for developers.
Frameworks and Libraries
React:
- Purpose: React is a JavaScript library used to build user interfaces, especially for single-page applications. It lets developers create reusable UI components.
- Considerations: Made by Facebook, it has a big community and lots of tools like Redux for managing state. It’s very popular.
Angular:
- Purpose: Angular is a comprehensive framework developed by Google for building dynamic web applications. It has a lot of tools for things like data binding and dependency injection.
- Considerations: It’s great for large-scale applications but can be harder to learn compared to other options.
Vue.js:
- Purpose: Vue.js is a progressive framework for building user interfaces. You can use as much or as little of Vue as you need, making it very flexible.
- Considerations: Vue is known for being simple and easy to learn, making it a good choice for both small and big projects. It’s user-friendly.
Back End Tech Stack
To build and maintain a reliable, scalable, and efficient SaaS application, you need a solid backend tech stack. This means using the right tools and technologies to ensure everything runs smoothly. Here’s a closer look at the key components and some popular choices:
