Yes, you can. Tools like Bubble, WordPress, Shopify, Wix and similar platforms make it possible to build simple web applications or websites without writing code. They’re useful for basic use cases, quick validations or content-driven projects. However, as the application grows in complexity, the building and maintaining of custom features, advanced workflows, integrations, performance requirements or scalability becomes more challenging. At that point, engineering skills are needed to ensure the application remains flexible, reliable and sustainable over time. Many businesses start on their own and later move to a custom-built solution when their needs outgrow simpler tools.
