Question: I'm looking for a solution that allows me to create and host web apps for free, without any coding knowledge.

If you want a tool to build and host web apps for free with no programming skills, Dream is the top contender. Dream is an AI-powered no-code web application development tool that lets you build and deploy full-fledged web apps as fast as you can type. It can integrate with services like OpenAI and Stripe, deploy with a click, and has features like bug fixing and database integration, making it good for a broad range of web apps.

Another top contender is Pico. Pico uses a text-to-app interface with ChatGPT and other AI models so you can build web apps by typing what you want your app to do. It offers instant deployment, easy embedding and built-in analytics, with several pricing tiers, including a free option for one app and unlimited users.

If you prefer a more direct approach, Bricabrac lets you generate web apps from text prompts and then customize them with a no-code editor. It offers free web app hosting and exportable code, so it's good for generating responsive, fully featured web-based tools and games.

Last, Glide is a no-code app builder that connects to existing business data in spreadsheets or databases and deploys apps on all devices with self-designing layouts. It includes data integration, powerful workflow development, and a range of customizable templates and resources to help you build professional-grade apps quickly.
