This is our curated list of open-source, no-code platforms to cut some of your developer-centric expenses.

Admittedly, software developers are amongst the highest-paid professionals. According to Forbes, product development is the number one expense for creating any application.

This proves a major bottleneck, especially if you’re a startup.

Catering to this specific use case, there are aplenty no-code or low-code platforms to build your product.

Low-Code vs No-Code

First things first, there is nothing such as No-code in application development. There will always be code running in the background handled by software professionals.

But with No-code software, you don’t write a single line of code. A simple drag-and-drop interface and your application will be up and running.

Conclusively, this also means limited customizations. No-code platforms are aimed at non-coding tech-savvy users.

However, if you can include a few scripts to enhance the overall user experience and functionality, that would become a low-code development platform like Tooljet. So, a low-code doesn’t mean code as an essential requirement; that’s optional but is used to add custom flavors in any application.

So, low-code software are assistive tools aimed at coding professionals to speed up software development.

And finally, a low-code platform can function like a no-code, but the opposite isn’t true.

While you can start with any, this article is about open-source low-code platforms.

Trusting open-source applications always proves best. First, the code is publicly available and audited most of the time, so you can rest assured about any malicious code or vulnerabilities.

And then you can always fork out once you grow in numbers.

So, without any ado, let’s start with the list of some of the best open-source low-code platforms.
