One of the most interesting options is Noodl, an open-source low-code platform that's boosted by AI. It's got a visual interface for development, customization and reuse of modules, and it can save you a lot of coding time. Noodl's AI generates building blocks, database queries and UI elements, so it's good for prototyping and then scaling web apps even if you don't know how to write a lot of code.
Another interesting option is GPT Engineer, which uses natural language processing and AI to speed up development. It's got an interactive prototyping interface and a natural language editor that turns plain text into code so you can build and deploy web apps. It's designed to bring software creation to people who don't know how to code.
For a no-code option, Dream is a good option. It lets you build and deploy full-fledged web apps with no code at all. Dream has integration with services like OpenAI and Stripe, one-click deployment and automated bug fixing. It's a general-purpose tool that can be used to build a lot of different types of web apps, from chatbots to landing pages.
