Why Do You Need a Next.js SaaS Boilerplate?

SaaS boilerplates definitely make your development cycle easier. That’s why boilerplates and starter kits have been in higher demand over the last few years. Below are the solid reasons why you should choose one.

Saves Time on Setup: Building everything from scratch takes a lot of time. With a SaaS boilerplate, you get the foundation ready to go, so you can start building your actual product faster. Time saved here is time gained for growth, marketing, and customer acquisition.
Focus on Business Goals, Not Infrastructure: Developers don’t have to reinvent the wheel when it comes to user management, payment systems, or security. The boilerplate takes care of these technical complexities, allowing you to focus on building what makes your product unique.
Fast Prototyping for Validation: A SaaS boilerplate helps you launch faster, so you can validate your product idea and market fit sooner. This is crucial for SaaS startups where speed and adaptability are key.
Faster Time-to-Market: The sooner you launch, the sooner you start getting feedback, adjusting, and iterating to improve the product. In a competitive market, speed is often the difference between success and failure.
Smart Work Over Hard Work: Why build things that have already been done? A boilerplate takes care of the basics, so you can focus on the important stuff. It’s all about working smarter, not harder.
Reduced Development Costs: With a pre-configured boilerplate, you lower your development costs. You’re not paying to build basic infrastructure, but rather focusing your budget on improving your product’s value and user experience.

With Next.js, a developer-loved framework, and an excellent boilerplate, you have the tools to build an amazing SaaS!

Here is our comprehensive blog on the benefits of using a SaaS boilerplate. Reading this will provide you with valuable insights and key points to consider.

How to Choose the Right SaaS Boilerplate for Your Product?

There are many SaaS boilerplates on the market, but it’s important to choose one that fits your project’s needs, is easy for you to work with, and offers flexibility for customisation. Here’s a guide to help you decide:

What framework are you comfortable with?

Think about the technology you’re most comfortable with and prefer. Are you a fan of React? If so, Next.js is probably the best choice for you.

You don’t want to waste time learning a new framework just because it’s trendy. Stick with what you know, or go with something you're excited to learn, as it’ll make development faster and smoother.

Do you have a preferred styling solution?

Styling is a big part of building a SaaS product. Look for a boilerplate that fits your design needs. Does it come with a CSS framework like Tailwind CSS? If you prefer a particular styling tool, make sure it’s integrated or easily adaptable. This saves you from having to rebuild the front end from scratch.

Do you need specific app functionalities?

Consider the features that you use in almost every SaaS application. For example, authentication and user management are common in most apps. Does the boilerplate include them?

Make sure it has the key functionality you need without extra bloat. It should give you the foundation for things like user sign-ups, payments, and profile management.

What tech/tools are you confident with?

Think about your strengths as a developer or what you’re already familiar with. For example, if you're confident working with Supabase for databases or prefer Stripe for payments, choose a boilerplate that uses those tools. You won’t want to switch tech stacks or tools every time you start a new project, so pick one that aligns with your expertise.

Is your SaaS boilerplate flexible enough?

You want a boilerplate that gives you room to grow but isn’t too rigid. If you need flexibility, make sure the boilerplate allows easy customisation. Check if the structure is clean, modular, and easy to tweak as your app evolves. The more flexible the boilerplate, the less time you’ll spend refactoring code down the line.

Customisation and Tech Stack Customisation

This is a very important factor to consider for a SaaS product, especially as your business grows. The boilerplate should allow you to add features and update tech stacks as needed. Ensure it’s built with a modern and scalable tech stack that’s easy to maintain. Whether it’s Next.js, Supabase, or Stripe, make sure the tech aligns with your long-term goals.

Licensing and Legal Considerations

When choosing a boilerplate, check its licensing. Some boilerplates are open-source and free to use, while others require a commercial license. Make sure the licensing terms fit your business model, whether you’re bootstrapping or scaling. You don’t want any surprises down the line.

Reviews and Feedback from Past Users

At last, take a look at what other developers have said about the SaaS boilerplate. If possible, check reviews, testimonials, or GitHub issues for feedback from past users. This will give you an idea of how reliable and useful it is in real-world projects.

Don’t just trust the marketing material—explore community discussions or support forums to understand common pain points.

In the end, it’s important to choose the right SaaS boilerplate that fits your needs, preferences, and future plans. But remember, no boilerplate is perfect from the start—you’ll need to customize and adjust it to fit your specific needs.
