What is SaaS? Exploring cloud-based software and its key characteristics

How do SaaS applications work

How do SaaS applications work?

SaaS (Software as a Service) is a software delivery model according to which applications are hosted by a service provider and are available to users over the Internet. Instead of buying and installing software on individual devices, users can access and use it through a subscription-based model via a browser. SaaS web applications eliminate the need for upfront investment in infrastructure and provide users with flexibility, scalability, and automatic updates. 

SaaS operates on a client-server architecture, where users access the application through web browsers or dedicated client software. The application is hosted on servers in the cloud, allowing for scalability. Data is stored securely, and multi-tenancy enables multiple customers to share the same instance while maintaining data isolation. SaaS platforms often provide APIs for integration with other systems, and updates are deployed automatically to ensure users have the latest features and fixes.

In recent years, we have seen impressive growth of SaaS in popularity; for example, the SaaS market was estimated at $197 billion in 2023 and is expected to reach $232 billion by 2024.

Key features and characteristics

Let’s explore the core features that define the SaaS approach and contribute to its widespread adoption. By delving into these characteristics, we can uncover the fundamental aspects that set SaaS apart from traditional web apps.

Centralized hosting

The software application is hosted on servers managed by the SaaS provider. These servers process and store data, allowing users to access the application from anywhere with an Internet connection.


SaaS based applications are designed to serve multiple customers simultaneously using a multi-tenant architecture. Both the software program and the database are shared by every customer. Data for each renter is separated and inaccessible to other users.

Subscription model

SaaS operates on a subscription-based pricing model. Users pay a recurring fee to access and use the software, often monthly or annually. This subscription fee usually covers software updates, maintenance, and support services. For example, the SaaS platform Dropbox is quite popular, which is not surprising because the platform offers cloud storage, tools for collaboration, security, and a subscription-based pricing model. Such a payment system allows customers to access the service for a monthly or annual fee.

Customization and configuration

SaaS platforms often offer customization options that allow users to adapt the software to their specific needs. This can include customizing settings, configuring workflows, and adjusting the user interface to the organization’s requirements. Among the popular custom SaaS platforms, we can highlight Editor X. With this platform, users can develop complex websites with cutting-edge design, using various layout capabilities as well as website builders where users do not need to have technical knowledge to create a web page for their needs.

Integration capabilities

SaaS-based applications often provide integration capabilities to connect to other software systems and services. This enables users to optimize workflows by sharing data between different applications and automating processes. One prime example of a SaaS application with integration capability is Freshdesk. It is a customer communication management platform that allows companies to start supporting clients as quickly as possible without requiring a costly adaptation plan or excessive manual work. The platform’s integration capabilities allow teams to integrate with a variety of cutting-edge applications to enhance the support approach.

So, having explored how the SaaS model works and its main characteristics, let’s move toward the pros and cons of SaaS for a deeper understanding of what you can expect from developing such a product.

The good and bad of SaaS: exploring the pros and cons of cloud software

Pros and cons of SaaS

Pros and cons of SaaS

The pros of SaaS


SaaS web application development often requires fewer resources compared to traditional software creation. By utilizing cloud computing models and pre-built components, companies can avoid substantial upfront hardware costs and reduce the need for extensive infrastructure setup and maintenance. This leads to significant cost savings during the development phase. Companies that provide SaaS based applications reduce maintenance costs by 16.1% with the public cloud, as opposed to supporting traditional applications.

Subscription-based pricing model

SaaS solutions offer a subscription pricing model that provides predictable recurring revenue for companies. This model improves financial planning and stability by delivering a consistent revenue stream over time. It is also possible to provide short free or discounted trial periods so that customers can explore the features of the app before making a decision. This helps to build a solid customer base of users who really need the application.

Scalability and flexibility

SaaS web applications are built to be highly scalable and flexible. Developers can easily accommodate a growing user base and handle fluctuating demands by leveraging cloud-based infrastructure. Scaling resources up or down can be done seamlessly, ensuring optimal performance and user experience during periods of high demand or growth. It is known that 37% of companies use cloud services because of their high level of flexibility.

Simple to use

SaaS products are easily used because best practices and code samples are already integrated. Users can evaluate software functionality or a new version in advance by running trial versions. In addition, your customers can seamlessly migrate to using multiple instances of different versions, all of which items do not require technical skills. Such ease of use provides the best user experience and increases customer loyalty.

Minimal upfront cost

SaaS development services have the advantage of exceptionally low upfront fees, making it easier for businesses to partner and invest in a SaaS plan. The pay-as-you-go model allows companies to commit to purchasing a SaaS solution only when they expect business growth, eliminating the risk of significant financial loss. Reduced customer commitment allows you to partner and provide subscriptions without significant upfront investment. This lowers the barrier to entry, increases the potential customer base, and improves the overall profitability and sustainability of the SaaS business model for providers. 

Drawbacks of SaaS

Despite its numerous advantages, web application SaaS also presents certain drawbacks that should be considered when evaluating its suitability for specific business needs.

Dependence on the service provider 

With SaaS, businesses depend on the application service provider vs SaaS for the application’s availability, performance, and functionality. For example, if users of the application are uncomfortable with any features or if any functionality is lacking for ease of use, you will need to contact the provider to implement any changes. This dependency can affect delays in updates, which can lead to user churn or a reduction in customer loyalty.

Potential for distrust from clients

Though web application SaaS usually provide robust security measures, there is a risk that customers may have concerns about data security and privacy. This distrust can arise from data breaches, unauthorized access, or vulnerabilities in the SaaS provider’s infrastructure. Application service provider vs SaaS need to prioritize robust security practices, implement encryption protocols, conduct regular security audits, and provide transparent information about their security measures to build trust and address customer concerns.

Nothing in this world is perfect, and neither is the SaaS model, but in this case, the pros really do outweigh the cons. Since we have explored SaaS key characteristics, its advantages, and disadvantages, let’s now focus on studying another prominent category: web applications. 

Web applications: detailed overview

This section will examine a web application, its distinctive features, its benefits and drawbacks. We’ll uncover the realm of web applications and identify the unique advantages they offer in the ever-evolving software development landscape.

Web applications workflow

Web applications workflow

While web SaaS has gained significant popularity in recent years, web applications have been a staple in the digital landscape for quite some time. And as we can see from the statistics, such applications have not lost their popularity in recent years, and it is expected that the market for web applications will reach $10.44 billion by 2027. 

In general, web applications are software programs accessed through web browsers that allow users to perform various tasks or access specific functionalities over the Internet. They are typically built using web technologies such as HTML, CSS, and JavaScript stack and can offer various features that can help automate tasks, improve performance, and streamline workflows. Web applications can usually be accessed from any device with an internet connection and are often hosted on a web server.

It is important to realize that web applications are a broader term covering different types of applications accessed through web browsers, and the difference between web applications and website is quite blurred. On the other hand, SaaS is a specific category of web applications that operate under a subscription-based model. Comparing SaaS and web applications directly is inaccurate as SaaS is a subset of web applications with distinct features and deployment models. Instead, we can explore their characteristics, benefits, and considerations to make informed decisions based on specific business needs and goals.

Key features and characteristics

Understanding key characteristics that define web applications will shed light on the unique aspects of such apps and help you understand their nature compared to SaaS model.

Platform independence

Web applications are built using web technologies such as HTML, CSS, and JavaScript stack, making them platform-independent. They can run on various web browsers, such as Chrome, Firefox, Safari, and Edge, without requiring any specific installation or configuration for different operating systems.

Collaboration and sharing

Web applications facilitate collaboration and sharing of information among users. Multiple users can access and interact with the same web application simultaneously, allowing for real-time collaboration, data sharing, and concurrent editing.

Social integration

Integrating social features into web applications can increase user engagement and build community. Using social media, users can easily share their wish lists, leave reviews, and even place orders, thereby increasing their interaction with your brand. 

So, after exploring what web applications are and their main characteristics, let’s explore the pros and cons of this type of application. In the next section, we will delve into the pros and cons of web applications, providing a comprehensive understanding of their benefits and potential drawbacks.

Factors to consider when choosing between SaaS and a traditional web application

In this part, we’ll look at the factors that need careful consideration when choosing between developing a SaaS or web application. By examining them, you can confidently navigate your decision-making process, ensuring your choice aligns with your goals.

Important factors before making a decision

Important factors before making a decision

1. The business goal

One of the most important factors to consider when choosing between a SaaS application and a regular web application is the business purpose. The SaaS model is primarily a business model. SaaS is worth choosing if your goal is to sell your application on a subscription basis to other companies or make the platform available to a wide range of customers. The SaaS approach can even be compared to the B2B model since you are offering your platform to other businesses in most cases. 

Web-based applications can also be designed to serve multiple customers or organizations in the same way as SaaS applications. But while SaaS applications are usually offered as a centralized, multi-tenant solution to various customers, web applications can be designed and deployed for a specific client or organization, providing a more tailored and specialized experience. A clear definition of your business objective will be the starting point in the decision between regular web applications and SaaS solutions.

2. Customization requirements

Assess the level of customization your application requires. SaaS applications often offer standardized features and limited customization options to cater to a wide range of users. If your business demands unique workflows or specific functionalities, a web application provides greater flexibility for customization.

3. Focus on company size and business specifics

For start-ups and small companies, off-the-shelf SaaS systems may seem advantageous due to their cost-effectiveness and speed of implementation. However, as a company grows, the limitations of SaaS functionality may need to be improved, resulting in a custom web application to meet specific requirements and provide scalability. Custom web applications offer greater flexibility to customize features to meet the company’s changing needs, ensure optimal performance and cater to unique business requirements. 

4. Cost сonsiderations

Evaluating costs from a company’s perspective is critical to making an informed decision that fits its budget and long-term financial goals. By choosing a SaaS model, companies can take advantage of subscription-based pricing, which often eliminates the need for upfront investment in infrastructure. It’s also much more expensive to write a product from scratch. This allows companies to manage costs more efficiently and direct resources to other areas of activity. In contrast, web-based applications may require more upfront development costs, but provide greater control over ongoing maintenance and infrastructure costs.

By considering these factors, enterprises can make an informed decision as to whether SaaS or web-based applications are appropriate for their specific needs. Each factor is weighted differently depending on the organization’s requirements, budget, scalability goals, customization needs, and data security considerations.

Are there any drawbacks to using SaaS?

One drawback is the dependency on the service provider, as businesses rely on their infrastructure, updates, and support. Additionally, security and data privacy concerns may arise, especially when sensitive information is stored or accessed through a third-party provider. Limited customization options may also be a drawback for businesses requiring highly tailored solutions.

Can I switch from SaaS to a web application or vice versa?

Switching from SaaS to a web application or vice versa is possible but may involve challenges. You may encounter problems such as complex and time-consuming data migration, integration changes, and adaptation to different infrastructure and deployment models. This requires careful analysis, planning, and possible adjustments to ensure a smooth transition. But before moving as a business owner, you must ask yourself why you need it and what it will bring to your business. It all depends on the specific case. For example, if SaaS provides you with the necessary minimum, then there is no point. 

Can web applications be hosted on cloud platforms?

Yes, web applications can be hosted on cloud platforms, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP). Cloud hosting offers scalability and flexibility for web applications.

Can SaaS and web applications be used offline?

Whether SaaS and web applications can be used offline depends on the specific product’s features and design. It is essential to consider the specific needs and requirements of your application when determining its offline usability.

What are the typical pricing models for web applications?

Typical pricing models for web applications include several options. One-off payment models involve a one-off upfront payment for the perpetual use of the application. Subscription-based models offer recurring payments at regular intervals, often monthly or annually, providing access to the application and its updates. These pricing models offer flexibility, allowing companies to choose the approach that best suits their revenue goals and customer needs.
