The perfect tech stack for startups in 2021

Three main characteristics make the best tech startups. Firstly, they have a talented and skilled team. Secondly, they have wonderful ideas. Besides that, they also have the necessary startup tech stack to put it into action . The world’s best ideas will face significant challenges if the founders choose to use complicated, burdensome, or out-of-date technology. So, as a founder, how do you choose the right stack in 2021? Therefore, to help you make the smart decision, in this blog, ArrowHiTech will bring to you The perfect tech stack for startups in 2021. Thus, don’t miss any part in our article. Let’s explore right now. 

What are Tech stacks?

For storing and processing the technologies used to build a product, tech stacks are commonly referred to as the data ecosystem. Web apps, mobile apps, and enterprises all have different tech stacks. Moreover, factors such as launch time and hiring a dedicated staff have an impact on the tech stacks. 

Furthermore, tech stacks are a combination of 2 aspects of software development: the frontend and the backend. The frontend is the actual ecosystem with which your users will interact. Whereas the backend includes the server, the web app, server, database, and the programming language. So, if you want to choose the best tech stacks for your entrepreneur, you should be aware of the factors that influence your decision and help you make the best choice.

Why is Startup Technology Stacks important for teams?

  • The technology stack you choose now is regularly difficult to change later. It is not an easy task to rewrite an entire system from Python to PHP. It would be difficult to migrate all of your databases and connectors from MySQL to NoSQL.
  • Migrating from one cloud or hosting supplier to another can be difficult as well. 
  • Changing the stack is expensive for a variety of reasons. It may require the hiring of new developers or the retraining of existing ones.

The tech stack for startups you select now will support you through the most critical stages of your startup’s funding process. Therefore, the stack you choose must be robust, adaptable, and scalable.

What are the most important factors to consider when choosing a Tech stack for startups?


The cost of the language or platform should be your main consideration. However, founders should not consider these costs solely in terms of upfront licensing costs. Rather, what are the initial costs, as well as the ongoing maintenance costs, associated with a specific tech stack? Is there a cost for security or liability? For example,  CentOS Linux is free. Whereas Red Hat costs a minimum of $350 per year for one server. However, Red Hat commonly receives security patches for major issues within days or hours. CentOS may not receive them for several weeks or months. If you store customer data on your server, the $350 fee may be worth it to ensure it is as secure as possible!

Furthermore, Developer wages also play a role in this as well. Common, well-known technologies, such as HTML, Swift, JavaScript, PHP, and C#, all have a large number of developers available. This helps drive down costs. Because obscure technologies, such as assembly language, have fewer developers. So they can charge higher prices.

In general, it’s best to choose a basic, well-known, open-source technology that provides the features you require. Therefore, your continuing maintenance and labor costs will be kept to a minimum.


The longer your project reaches the market, it will be more difficult to succeed. Because your competitor may get their idea out first.  Or, you may run out of money battling a technology that is incredibly slow to use.

Therefore, you should choose technology solutions. Because it will help your startup achieve more. Selecting technologies which will be a burden to your team and company is not a good idea. Thus, choose technology that is simple to integrate and has third-party controls and support. These functions will make it simple for you to use.


Your startup will not last long if there are only ten people using your app or service. So consider scalability from the beginning. Choose a technology that will allow your startup to scale as it grows. Even large corporations are vulnerable to this, as evidenced by Disney+, which crashed on launch day due to unexpected demand. Therefore, you should prepare for your app’s success by choosing a server-side technology, such as PHP, Ruby, or Python, and cloud infrastructure, such as AWS or Azure, which can scale with it!

Benefits of selecting the right Tech stack for startups.

Choosing the right Tech stack for startups is critical. Because it will be used for the period of your startup. Moreover, it will support your business. The right Tech stack for startups will help your business in three ways:

  • Firstly, thanks to the right technology stack, you can create a minimum viable product (MVP) easily. This term refers to the basic features that must be available in your product in order for it to function. For example, the MVP of a file uploading site allows the user to select a file, successfully post it to your server, as well as download it again. It doesn’t require all of the fancy UI bells and whistles, or other features like pausing and restarting an upload. The MVP is the first version of your project. Therefore, you can send it to your investors. Because the process of from idea to MVP is so time-consuming. Therefore, selecting the best full tech stack is critical to getting everything to run quickly.
  • Thanks to the fantastic technology stack, developers are able to add new features easier. Therefore, developers can quickly add customer-requested features. If you’re stuck in seeking someone who knows an obscure language, you’ll struggle to iterate quickly enough to retain and catch customers’ interest.
  • Finally, a good stack is simply enjoyable for developers to use! It comes with documentation and plenty of examples, and it works well. As a result, you’ll have a cleaner, more robust codebase with fewer bugs. In addition, if there are bugs, your developers will be able to fix them faster. This leads to higher customer satisfaction. Therefore, choosing the right stack encourages good software practices. These practices will make your developers’ lives easier. As a result, it allows them to create better software for their customers.

Results of selecting the wrong Startup Technology Stacks.

There are typically two issues with selecting the incorrect stack for your new startup:

  • Firstly, you can use a legacy stack that fewer and fewer developers want to use. This will make it more difficult to find qualified developers. Therefore, bug fixes for this stack can be slower. This will lead to risk exposing your company to legal liability. Moreover, it does not scale well. All of these will have a negative impact on your customers’ and developers’ lives.
  • The other issue with a bad stack is that the only way to fix it may be a complete rewrite. It will be expensive and endanger your entire startup. Assume that you choose technology X for your startup company. After six months of working with X, you notice that it appears flaky to about 10,000 users. Perhaps it won’t work across multiple machines, and the largest VM available from AWS can only handle 10,000 users. Thus, you have to rewrite the entire codebase in a scalable language such as Ruby or PHP. But that’s not a simple task. Because you’ll need PHP developers who can ensure there are no regressions. Besides that, I t could take a long time, during which time your competitor can steal some of your customers.

How can select the Best Startup Technology Stacks?

Selecting the perfect tech stack for startups is not an easy task. It takes careful thought to ensure that you’re making the right decision. 

  • Firstly, you have to make the decision where your software will run. Is this a mobile application? Do you want it to be available on Android and iOS? Is this a web app, or both mobile app and web app? The stack you select is dependent on the platform where your code will run.
  • Secondly, you need to decide what kind of product you want to create. Are you creating a client-side application? After that do  you want to use one of the native frameworks like Swift and Kotlin. Are you developing a sophisticated AI algorithm? So  C and CUDA are a good fit for you. The majority of the tech stack discussion will relate to what you’re building and where it will run.
  • Thirdly, you should plan for the number of users you want in the first few months of your startup. Although you should choose a stack with scalability, you don’t need to implement advanced caching in PHP if your website receives five visitors per day. Knowing what frameworks to use is simple when you’ve defined your expected load.
  • Finally, are you looking for technologies that provide rapid prototyping? Or you’re seeking an MVP. So you can use a framework that is robust and scalable, even if it takes longer to code.

Which Startup Technology Stacks do big companies use?

Let’s take a look at what five well-known tech companies are using:

  • Facebook are using PHP, React, Cassandra, Jes
  • Airbnb are using PHP, Python, JavaScript, Java, Ruby
  • Letgo are supported by PHP, Symfony, MySQL, Python
  • SpaceX: PHP, Python, JavaScript, Java, Ruby, C/C++
  • Slack: PHP, Python, JavaScript, Java, Go, Ruby, C/C++, Kotlin, Objective-C

  • It is not immediately accessible after implementing Visual Studio Migration of applications from.
  • Expensive.
  • Managing code can be more time consuming than native code.

Some of these Tech stack for startups provide significantly more features than others. The simplicity of use and extensive libraries in Python enhance developer productivity more than any other language. It is also the best option for AI and ML- based development. Moreover,  Java has an impressive identifier. Because it defines and confirms bytecode before it is executed. Furthermore, it provides maximum flexibility to store and recover information because it follows the LIFO principle. For these reasons, Java and Python are the best technology stacks on the market.

Mobile app development Technology stack

In iOS and Android, there are different frameworks to use for Mobile app development services 

For Android

Kotlin is a programming language which is designed specifically for use with Java. Kotlin is supported by Google for Android development. Besides that, it is available as an alternative to the Java compiler in Android Studio. More importantly,  Kotlin lessens the programming time needed for app development.
