Build Real App with Base44 & Claude Code - Build a working web and mobile app from one shared backend

by•
I built a working web and mobile inventory app using Base44 and Claude Code, starting with the web version, shared backend, database, and authentication, then extending the same product into a React Native and Expo mobile app. This webinar shows the full beginner-friendly workflow, including prompt structure, VS Code setup, step-by-step testing, receipt uploads, and web-to-mobile sync so you can reuse the same process for your own app ideas.

Hi Product Hunt 👋 This webinar is a practical beginner-friendly guide to building a working app with Base44 and Claude Code. The main question is simple: how can you go from an app idea to a working web and mobile product without building everything from scratch? We start by using Base44 to create the web app, backend, database, and authentication. Then we keep that same backend and use Claude Code to build a custom mobile frontend with React Native and Expo. Inside the webinar, I cover: - How to turn an app idea into a working Base44 web app - How frontend, backend, database, and authentication fit together - How to move from Base44 web to a Claude Code mobile project - How to build with small prompts, checkpoints, and testing - How to connect web and mobile through the same shared backend The goal is to give beginners a simple mental model for AI-assisted app building: keep what already works, build one feature at a time, test it, and then continue. We also include the prompts, VS Code commands, setup steps, and testing checkpoints used throughout the workshop so you can recreate the workflow for your own app. Curious to hear from you: what kind of app would you build first with Base44 and Claude Code?
