Why you should opt for a no-code / low-code platform

In addition to the fact that low-code development is much simpler than manual coding, there’s a range of other benefits this approach brings. 

  • Higher speed. You have no more need to spend weeks or months on developing an internal tool or a web app. Such low-code platforms as UI Bakery, Retool, and other internal tools allow you to build the needed app in days or even hours.
  • Reduced costs. Low-code internal software allows you to save development costs. You don’t have to hire new developers and pay to them or distract your own development team from their core critical tasks. 
  • Simplicity in use. You don’t need any front-end development and design skills to create a functional internal tool with a no-code / low-code development platform. Even a non-techie can handle it. However, some tools are a bit more complex than others (e.g., Retool and its alternatives). To utilize them to the full, you need to have some basic understanding of how apps are developed.
  • Debugging and maintenance. Modern internal tool builders allow you to fully control the apps you create. They have unit testing and visual debugging capabilities. You regularly receive audit logs that you can investigate to track your application usage and debug issues. Version control is also provided, and it allows you to roll back changes when needed.
  • Third-party integration capabilities. There’s always the need to connect an internal tool or a web app you’re building to third-party APIs, business apps, or legacy systems. The integration process involving data mapping, filtering, etc. is rather simple in such tools as UI Bakery. 

To sum up: how to choose the right low-code tool

The variety of low-code and no-code tools is rich. The 4 most powerful apps and internal tools builders we’ve covered above can provide you with a range of benefits. However, the number of all the available low-code platforms that can compete with Retool is much bigger. 

When opting for a particular development platform, keep in mind that all these tools aren’t meant to become an alternative to coding. Their aim is to help you save hours and days spent on development and allow your teams to focus on the tasks that are critical for your product or services.

Pay attention to the feature set each low-code platform offers, the pricing plans, their integration opportunities, app deployment options, the number of predefined building blocks you can work with, etc. Your choice should depend on a number of factors. Eventually, a no-code / low-code tool you choose can become the most cost-effective solution that will allow you to automate a range of processes and ship the needed apps to your teams or clients much faster.
