The Comprehensive Guide to Low-Code

Low-code is changing the way companies optimize their processes as business and customer demands change.

Without the need for extensive coding, low-code applications can be created quickly to improve data management, production efficiency, and much more.

This guide covers all there is to know about low-code and its impact on modern application development. Enjoy the read!

What is low-code?

Low-code is a development approach that uses visual user interfaces for building applications, moving away from traditional hand-coded programming often associated with application development. This method requires little programming knowledge, relying on visual elements that can be dragged and dropped to create applications relatively quickly and easily.

Think of flowchart web applications like Miro or Lucidchart. Now imagine each shape is a reusable component of code that can be pieced together to create a process model: the visual representation of the steps and processes that an application will automate, along with the business processes it can support.

Code terminology
What does it all mean?

Low-code refers to an application development approach that employs visual tools and pre-built components to simplify application creation. This approach reduces the need for extensive hand-coding, making application development more accessible to a broader range of users, i.e., non-developers.

Low-code platforms 

A low-code platform, like Mendix, is a software environment that provides the necessary tools and frameworks for low-code development. These platforms enable users to build, test, and deploy applications through intuitive visual interfaces and built-in integration capabilities. 

Low-code applications

Low-code applications are pieces of software created using low-code platforms. They can range from simple tools for smaller businesses to complex enterprise systems that keep manufacturing companies and other industries on top of their assets and processes. These applications are developed with minimal manual coding and often with significant involvement from non-technical professionals. 


No-code platforms help users build applications entirely through visual interfaces and pre-configured components without writing code. These platforms are designed for non-developers, allowing them to quickly create and deploy simple applications to solve specific business problems without any intervention from IT. While no-code has an even lower barrier to entry than low-code, it doesn’t offer the same flexibility for developers, who can easily add custom code while developing applications on a low-code platform. 


High-code development refers to traditional software development methods that involve extensive manual coding by professional developers. It often relies on JavaScript frameworks like React or Angular, or those specifically designed for mobile or native applications. While it provides maximum control over the application, it requires significant time, specialized programming skills, and resources to build, maintain, and scale complex applications. Using only high-code makes businesses rely on developers, taking time away from creating new features and improvements.

The benefits of low-code
How can low-code help?

Low-code has several functionalities that make it an easy choice for companies looking to digitize their existing processes, upgrade legacy systems, and establish protocols that avoid messy data silos with no ownership or transparency.

Low-code visual development

Low-code development relies heavily on visual interfaces to help teams create applications. This includes using pre-built templates that can be dragged and dropped into certain positions to develop a process model.

Rapid application development

Without the need for extensive hand-coding, low-code allows businesses to quickly develop applications and make iterations. This is also helped by the low-code platforms’ visual interfaces, allowing non-technical personnel to easily see, understand, and comment on an application’s process model. The more precise the feedback, the quicker an application can be adjusted.

Accessibility and collaboration 

As described above, low-code platforms make software development accessible to non-technical individuals. Sometimes referred to as “citizen developers,” these individuals often don’t have extensive programming knowledge, if any. Fortunately, low-code platforms use visual interfaces with visual components, allowing those from different professional backgrounds to understand the how and why of an application through a process model.

Low-code integrations

Low-code platforms often come with pre-built integrations, meaning that the applications you build using low-code development can be linked to existing systems and data sources. This could mean connecting to inputs such as physical sensors on the factory floor or outputs like a customized data dashboard that gives an overview of production rates and machine statuses. This also means that low-code applications can be integrated with Siemens Xcelerator, SAP, Salesforce, IBM, and SIG.


Low-code platforms aim to minimize coding, lowering the barrier to entry for non-technical personnel to provide helpful input during the creation of an application efficiently. However, if there are specific requirements, low-code platforms allow developers to step in, so to speak, and add custom code and integrations.  


Applications built on low-code platforms allow businesses to scale without needing to be completely redeveloped. This is because low-code component templates can be added or expanded as needs evolve without disrupting the entire process model.  
Low-code platforms also support horizontal and vertical scaling. This could include adding more copies of an existing component to distribute an increasing workload or simply enhancing the capacity of a single resource by upgrading its memory, CPU, or storage.

Cost efficiency

Low-code platforms reduce the time required and specialized skills needed for application development. Extensive training is unnecessary as low-code interfaces are more intuitive than Python, Java, and PHP coding environments. Maintenance for low-code platforms is also more straightforward, as platforms are cloud-based with integrated security protocols. In short, fewer resources are required to keep a low-code platform securely up and running.
