Hi Friends, my name is Callum aka wanderloots. In today's video, I walk through how I use Firebase Studio To Build & Deploy A Full Stack App (for free) 🚀💡 This video gives my step-by-step process & strategy how to build a complete app from scratch with Firebase Studio, including backend & authentication with AI coding (vibe coding) Update: Firebase is a Google Developer tool that helps you add complex features to your apps, including backend with database, pricing, & authentication. Firebase Studio has a prototyping agent that helps you build the frontend and wire it all into your Firebase Projects. I walk through how you can set up Firebase Projects, Firebase Studio, and a suite of Google features that help you get your app from a basic prototype into a fully functioning application, along with some tips & strategy for prompting, context engineering, and security considerations. Whether you're a complete beginner or have experience coding with AI, this video will help you piece together your full stack application and prepare for adding a wide range of complex features. My previous videos on app-building give more context on how to use AI to strategically build apps. Build - Deploy - If you have any questions about Firebase, Firebase Studio, Google AI Studio, or vibe coding in general, please let me know in the comments! It's honestly amazing how much I've learned and built in such a short time, leveraging Gemini 2.5 Pro as one of the most powerful LLMs out there, especially for coding (and it's free!). With Obsidian being my favourite non-linear note-taking app, I thought it would be cool to build a custom, personal app for myself: an idea inbox. A dedicated mobile app that lets me drop thoughts & ideas in one place and have them appear in Obsidian for analysis later. Whether you are interested in Obsidian or not, the concept of ideating, roadmapping, planning, and developing an MVP app for yourself remains the same. Prompt engineering & context engineering are becoming more important than ever as AI tools continue to improve. We need to consider how to scale our apps from MVP to production, leveraging AI for coding along the way. I hope you enjoy! ✨ To learn more about how the AI tools I use, check out my AI Learning Playlist: P.S.
