I’ve been building apps & SaaS products for a long time now. Most of my work was client-focused, and in that setup I always kept reusable kits/code snippets around as stubs to move fast.

Recently, I finally started diving into the B2C app market. After shipping my first app, I settled on a stack that felt right: completely serverless, using a mix of Firebase + Supabase.

Over time, I plugged in everything I usually need as a solid starting point:

• Auth
• Push notifications
• Lightweight admin
• Cloud Function definitions
• Supabase migrations & CRON jobs
• Firebase & Supabase CRUD helpers

I also kept the frontend intentionally lightweight and AI-friendly. I like designing my own UI/UX, so instead of using component-heavy libraries like React Native Paper or Kitten, I went with NativeWind. It works perfectly with AI workflows, basically Tailwind for React Native.

At this point, I’ve been using this setup internally for myself, and I decided to make it available publicly as Simple Expo Kit.

I plan to actively maintain it because I already rely on it for my own projects. Whenever I need to bootstrap a new app, it now takes me just a few minutes to get moving.

I also wrote detailed guides on how to use everything properly. If anyone is interested or wants to learn more, I’d be happy to help.
