Google Antigravity + Claude Code 🚀 AI Coding Tips (Adding App Auth)

Hi Friends, my name is Callum aka wanderloots & welcome to Claude Code +Antigravity + Testsprite! (https://www.testsprite.com/?via=wanderloots) Google Antigravity takes AI Coding to the next level in a full IDE, letting you build apps & vibe code/AI-code assist on your desktop, Claude Code brings heavy coding power to keep you building & Testsprite makes sure the code actually works! ✨ UPDATE: https://www.youtube.com/watch?v=Jqypr_h4keg This video walks through a practical example of adding an authentication system to an RSS reader app (that I built in this video: https://youtu.be/MAUpppfg9Go), using a hybrid workflow of: 1) Gemini 3 Pro (for planning) 2) Claude Code (for building) 3) Testsprite (for testing) By using three separate AI coding tools, usage limits in each can be conserved, letting each tool do what it does best so you can keep building. If you want to check out Testsprite: https://www.testsprite.com/?via=wanderloots If you have questions on how to use AI testing tools, check out their discord here: https://discord.com/invite/QQB9tJ973e Antigravity has 3 major features I find sets it apart from other tools: 1) Agent Manger & Editor Shared Workflows 2) Agentic inbox for tracking parallel agent tasks 3) Browser agent for automated testing & debugging It's honestly amazing how much I've learned and built in such a short time, leveraging Gemini 3 Pro is one of the most powerful LLMs out there, especially for coding (and it's free!). Combining the context & planning power of Gemini 3 with the coding power of Claude (Sonnet 4.5 & Opus 4.5) in Claude Code really does streamline your building process in Antigravity. Adding Testsprite helps ensure that what you're building with Gemini & Claude actually works, so you can keep building without worrying about your app breaking. I hope you enjoy! ✨ To learn more about the AI tools I use, check out my AI Learning Playlist: https://www.youtube.com/playlist?list=PLWhMzDKA7vJ7k0CCHAhCNGXH1BKKEo_we P.S.
