Mendix is one of the low-code platform leaders, according to Gartner & Forrester. Founded in 2005 in The Netherlands, they were acquired by Siemens in 2018. They currently have a global presence to deliver their platform.
Their Mendix platform is a generic low-code platform, although they are fairly strong when it comes to building process driven applications. Their visual modelling toolset helps engineers in creating software at a fraction of the time compared to traditional development. But some coding is still needed.
Like many of its competitors they offer a free version of their platform, with limited capabilities.
