WEM is one of the first true no-code platforms that was available. Very easy to use, and quick to build applications. They offer a PaaS solution, but also a private cloud/on-premise options.
WEM has been around for some 20 years. But only the last 4 years they have turned into a product company, with their flagship product WEM. WEM is one of the very first no-code platforms that came into existence. The software runs in the cloud, although it can also be installed on-premise or in a private cloud. The WEM Modeler is the visual tool that is used to create applications, deal with the DevOps activities, etc.
WEM is based in Amsterdam, The Netherlands, and has a global network of distributors and partners.
