Build a Website Application for Free in 2 Hours with Vibe Coding

AI has really changed the game when it comes to building apps. Tasks that once felt like a grind are now automated or way simpler, and things that seemed impossible have turned into fun challenges. I’m a huge fan of Telegram for keeping notes because it’s super quick and easy to use. That habit sparked a cool idea: why not build my own note-taking app? It was also a great chance to mess around with some new tech. So, on a lazy rainy weekend, I kicked off a personal hackathon. After some brainstorming, I picked a stack that felt both powerful and easy to use. For hosting the frontend app, I went with Cloudflare Pages running React Native — super straightforward. For the backend, I used Cloudflare Workers with the Hono framework, which made spinning up the API really fast. To handle data, Cloudflare D1, a simple SQL database, was my choice. And for storing user images and canvas drawings, I set up Cloudflare R2 for object storage. The biggest help throughout was Claude Code from Anthropic, acting like my AI sidekick and helping build the app. Cloudflare’s infrastructure was a lifesaver. Their free tier is incredibly generous, which made the whole project cost basically zero, except for a small $10 expense on the domain name. Plus, built-in DDOS and bot protection gave me peace of mind from the start. I created a clear workflow with my AI agents to keep things on track. First, I’d ask the frontend AI agent to draft a design based on my system guidelines. After a quick review, I’d have Claude produce the full design along with an API spec in Markdown. That spec went into my knowledge base repo, where the backend AI agent took over and built the APIs. Once complete, the AI generated detailed API docs with endpoint examples. Then the frontend AI agent used those docs to integrate everything seamlessly. My role was mostly to review the final product once the loop wrapped up. The result? From nothing to a test-ready app in just 2 hours, at zero development cost apart from the domain fee. It really showed how combining AI with cloud services can turn rapid prototyping into a smooth, almost effortless process. This experience not only proved the power of cloud-based tools but also sparked ideas for future projects. It’s crazy how much you can build now without breaking the bank or needing a huge team.
