Software as a Service (SaaS) is a cloud computing model that provides customers with software applications and services over the internet without the clients necessarily installing the software on their local machines on a pay-on-demand basis. Instead, SaaS provides customers with all the necessary resources and carries out all the maintenance tasks on the application. SaaS providers offer clients a complete product that the service providers manage. The clients, after that, focus most on how to use the particular application. Some basic examples of SaaS applications include Customer Relationship Management (CRM), such as Zoho and Salesforce application, and Human resource management application, such as BambooHR, Gusto, and Zenefits.

On the other hand, SaaS frameworks are a collection of software applications for building or developing cloud-based applications that the users need. The frameworks entail libraries, tools, and infrastructure components used for creating and developing software as a service.

Best Framework for SaasS Applications

Some of the common SaaS frameworks used by developers includes:

• Symfony
• Ruby on Rails
• Django
• React
• Angular
• VueJs
• ASP.NET Core
• ExpressJs
• Angular
• Spring

While choosing a SaaS framework for use in the development of SaaS applications, some factors must be considered on which best framework to use depending on the need to be solved by the application to be developed. Therefore, this article presents some factors to consider when choosing the best SaaS framework. Some of the popular SaaS frameworks that are best to be used in SaaS application development are listed as follows:

• Symfony: 

This web PHP framework for developing web applications and web services. Symfony has reusable components and a modular structure that helps developers build robust and scalable applications. It also provides clean code, well organized in a design that makes SaaS application development more efficient and effective. Listed below are some of the features of the symphony that makes it the best SaaS framework:

• Modular architecture: Symfony is made of a collection of reusable components that can be used in any PHP projects
• Dependency injection: Symfony uses a dependency injection pattern which makes it easy to manage dependencies between its components,
• Debugging: Symfony provides an efficient debugging system that makes it easy to identify and fix bugs in an application being developed.
• Templating: Symfony includes a flexible templating system that makes it easy to separate the presentation logic from the application logic.
• Routing: symphony provides a standard routing system that enables developers to define URL patterns easily and maps them to specific controllers and actions.

Some of the best use cases for Symfony frameworks include:

1. E-commerce websites: Symfony is used to build large, scalable, and custom web-based e-commerce applications that handle a wide range of products and meet every client’s unique features.
2. Content management system (CMS): Symfony is designed to handle an extensive dynamic range. Its build architecture supports caching and security, making it ideal for building scalable, performance content management systems.
3. Financial applications: Symfony can be used to build financial applications that require handling sensitive information and transacting securely. This is to the needs of its specific features and compliance requirements.

Symfony is used in many large companies and a wider community. This makes it more reliable for SaaS application development due to its proper maintenance and updates from the larger community of users. It has also been used to develop custom applications such as e-commerce sites, content management systems, and web applications, making it best suit the SaaS framework.

• Ruby on Rails: 

Also known as Rails, It’s a popular and versatile framework for developing web applications. Its large and active community of developers provides it with a wide range of tools and plugins for building, testing, and deploying applications. Rails are known for their emphasis on convention rather than configuration, making developers focus most on writing codes rather than configuration work. Rails are based on the Model-View-Control (MVC) architecture that provides an easy-to-use interface for building robust and scalable applications. Some of the essential features that make it an efficient SaaS framework for application development include the following:

• Model view controls: Rails architecture separates an application into three main components, making it easy to manage and build different parts.
• Convention rather than configuration: Rails provides a set of default conventions for building applications, thus reducing the arrangements required.
• Community and plugins: rails has a vast community of developers that provides a wide range of plugins for adding additional functionality to the applications. This makes development more easy and fast.
• Build-in tools: rails provides a wide range of tools for everyday tasks such as routing, database migrations, and task scheduling, making application development easy and fast.

Best use cases for Rails include:

1. E-commerce applications
2. Project management
3. content management systems

• Django: 

This is a high-level Python framework for the development of web applications. It provides a clean and pragmatic design that makes it suitable for developing complex and data-intensive applications. In addition, Django has a robust Object-Relational Mapping (ORM) system making it easy to interact with the databases and manage complex data models. Django is also known for its wide range of tools for security, user authentication, and other common task such as routing, making it a popular choice for secure and scalable applications.

Common features of Django

1. Model-View-Template Architecture: this architecture separates the system application into three significant components producing clean codes that are easy to manage and debug.
2. Object-Relational Mapping: Django is an in-build object-relational layer making it easy to interact with databases and complex data models.
3. The Admin Interface: Django provides an in-built admin interface making it easy t perform basic tasks such as editing, adding, and deleting data.

Everyday use cases for Django include:

1. E-commerce websites
2. Web portals
3. Analytical dashboards
4. CRM (Customer Relationship Management) systems

• React

React is a half-fledged SaaS framework but a JavaScript library for building user interfaces. It was developed by Facebook and adopted a large community of users for front-end web applications. It is well known for its simplicity, versatility, and speed. React libraries allow the building of complex and dynamic user interfaces by breaking them into smaller reusable components that are easy to maintain.

While React is primarily used for front-end development, it can be combined with other SaaS tech stack to build a complete SaaS application using APIs and server-side technologies.

• Angular

Angular is a JavaScript-based framework developed by Google for building web applications. It creates single-page applications (SPA) and progressive web apps. In addition, it provides a set of features for creating complex and reusable front-end applications.

Some key features include data-binding, modular architecture, component-based structure, and reactive programming using RxJS. Angular and React have been widely used by many organizations and businesses for developing user interfaces for SaaS applications.

In conclusion, choosing the best SaaS framework for developing an application system depends on the specific needs and requirements of the project and the team using it. One needs to focus on the kind of application required. This is a result of different frameworks’ capabilities. Some can handle large and data-intensive applications, and others can be fast in developing applications due to comprehensive plugins and the library of use. It is essential to carefully evaluate each option on the project requirement, team skills, and documentation available.
