10 Open Source SaaS Boilerplates for your next side project

What is SaaS?

Software as a Service, or SaaS, is software available online. Since they are hosted in the cloud and used in a browser instead of downloaded to your device, SaaS applications such as Gmail, Salesforce, and Twitter are technically SaaS services.

SaaS is frequently used in business to refer specifically to a subscription-based billing model. This includes everything with a monthly subscription fee, from JIRA to ChatGPT pro. The most common type of SaaS companies (and arguably startups in general) are business-to-business (B2B) SaaS applications, which bill other businesses a monthly subscription fee.

Most SaaS apps have a lot of similar functionality in terms of technology. They all require, among other things, the ability to be deployed and hosted on cloud infrastructure, user accounts, a front end, a billing system, and more. Boilerplates come into play at this point.

What Are SaaS Boilerplates?

What if you discovered that a template could handle all the tedious, challenging tasks by beginning with a boilerplate that contains everything required, and you no longer had to do them yourself? The answer is yes, and a SaaS boilerplate is exactly what you need. Boilerplates for SaaS contain features that would otherwise take a lot of time and money to develop by business owners.

All SaaS apps share specific characteristics. Whatever you are building, your SaaS will probably require the following:

• The authentication feature manages all login, logout, and forgotten password situations.
• Integration with payments, a method of billing the client, and control over plans and subscriptions.
• Features for managing repeat payments, cancelling subscriptions, and charging credit cards.
• Pre-build permissions and roles management are used to grant and restrict user permissions based on roles with complete end-user control.
• Your users' dashboard
• User profiles
• Integrated component library
  

Boilerplates come in a wide variety of styles, each with its own capabilities and features that can be found on the market. Depending on your preferred programming language and the architecture you believe your SaaS platform will require, you can select one boilerplate or a starter kit that could serve as the foundation for your future projects.
