I can talk about one of the low code/no code product: Power Platform. It is a Microsoft’s low-code/no-code platform that let users create apps, develop workflows, develop chat and desktop bots and also use commoditized AI models. The platform is now in business since 4+ years and I know many Fortune 100 companies who have got 5000+ apps - both for internal org and for business with external partners, subcontractors etc. It is a massive thing. A simple license gets you a storage space in cloud, works with Teams, Office 365, Sharepoint etc and also apps thus developed (all using no code/low code approach) can scale (without rewriting using code) to talk to Microsoft’s business apps aka Dynamics 365 and 400+ other systems (inc Oracle etc)
I feel the view of ‘no code / low code’ is a bit primitive here. It used to be like that but last 3/4 years, the entire thing paradigm has changed fundamentally.
