Coming from Enterprise and having used Retool ~3 years, I am also buffled… low code biz apps is one of those product categories that seems good initally, especially if you never worked for a Corporation, but it is really not. These tools normally don’t do governance, testing, security, users management, that well, which puts them in direct competition with MS Access. If you think MS Access is old and not web based, just use it’s evolution: MS Power Apps. Can you compete in this area? Sure, but at 100$ per seat prices, about 3-5 times less these low code tools demand. By the way, I have been quite pleased with Flask Appbuilder, which has a clean approach to crud apps, has good governance, and it is truly open source.
