Top 3 Low-Code development platforms in 2021

Low-Code is not really new, but the scarcity of developers and skyrocketing demand from businesses for digital transformation have contributed to a renewed and sustained interest. Low-code is here to stay, so here’s the essentials of what you need to know!

What is a Low-Code Platform?

A Low-Code development platform is a Graphical User Interface for creating applications with less code, or no code at all. These tools can help minimize manual coding as well as offering quick setup, deployment, scaling and security. Low-Code platforms do not seek to replace developers but to free them up for more value-added tasks. For example, by using a Low-Code platform a non-technical user can create a user interface and connect it to third party services integrated in the tool, or even to a custom backend or cloud functions created by developers.

Benefits of Low-Code Tools

Good enterprise-level Low-Code platforms offer:

  • Up to 10X faster than traditional development cycle
  • Cheaper to produce and maintain
  • No-Ops, fully managed and scalable in the cloud
  • Less margin for error, safer, provides audit trail

Low-Code tools allow more people to contribute to the application development process, including non-technical people.
The main reasons why businesses are interested in Low-Code platforms are to:

  • Accelerate digital innovation and transformation
  • Focus on business logic instead of infrastructure, security, maintenance
  • Reduce the IT backlog and increase responsiveness
  • Reduce dependency on hard-to-hire technical skills
  • Protect against technology churn
  • Standardize app development processes

Limits of low-code and how to overcome them

People think about Low-Code is just for simple use cases because they see them mainly as UI tools with few pre-made integrations. The most agile companies extend the capabilities of those tools by leveraging microservices created by developers to unlock the true potential of Low-Code and address much more complex use cases.

A few concerns

Low-code isn’t the perfect least not yet. Users cite several concerns:

  • Lack of customization
  • Limited integrations
  • Locked-in with the platform

Those concerns are real!

Citizen developers will get projects started with low-code, but quickly hit limitations. That’s the right time to ask for developer assistance. The developer will be able to create customer components, plugins and APIs that the end user can consume to achieve custom complex tasks with the low-code editor.

Some low-code platforms have the capability to export the code and run it on-premise. One we really like is AppDrag. Another option might be to not store any data in the platform and use it only as a frontend to access your on-premise database. This approach is interesting but a lot harder than using the integrated tools to create and manage the database. It isn’t a one-size-fits-all.

So that’s the essentials. Now for the top 3 of 2021!
