Simple Expo Kit (SEK) is a battle-tested React Native boilerplate built for vibecoders, indie founders, and teams shipping with AI-first workflows. Instead of wasting weeks wiring infrastructure, fixing config issues, and debugging SDK conflicts, SEK compresses the entire setup experience into roughly 15 minutes so you can focus on product velocity and agentic coding workflows.
It ships with a production-grade stack out of the box, combining Expo, Firebase, Supabase, RevenueCat, and NativeWind into a clean starter architecture that’s deployment-ready from day one. Core capabilities include:
Authentication & Access Control
Built-in support for both Firebase Auth and Supabase Auth with ready-made flows for Google, Email, Apple, GitHub, X, and Instagram sign-in. Supabase projects also include preconfigured Row-Level Security (RLS) policies to simplify secure multi-user data access.
Subscriptions & Monetization
RevenueCat integration is already wired for handling subscriptions, in-app purchases, and paywalls across iOS, Android, and Stripe-powered web billing. Includes starter paywall screens and subscription tier handling so monetization doesn’t become an afterthought.
Flexible Database Layer
Choose between Firebase Firestore for realtime NoSQL workflows or Supabase Postgres for relational SQL architecture with migrations, RLS, cron jobs, and scheduled functions.
Serverless Backend Support
Launch backend logic instantly using Firebase Cloud Functions or Supabase Edge Functions for APIs, automations, and scalable server-side workflows.
Push Notifications Without the Pain
Comes with a streamlined Firebase Cloud Messaging (FCM) setup that avoids the usual configuration headaches and enables reliable cross-device push delivery.
Modern UI System
Uses NativeWind (Tailwind for React Native) with prebuilt light/dark theme support, giving developers full UI flexibility without depending on bloated component frameworks.
Developer Experience Optimized
Includes strict TypeScript typing, Expo Router file-based navigation, environment configuration, and starter screens like onboarding, dashboard, CRUD flows, and subscription pages to accelerate iteration.
Supabase CLI & Migration Workflow
Supabase projects include local database tooling, structured SQL migrations, and a scalable schema workflow designed for long-term maintainability.
Built for AI Coding Agents
SEK is intentionally structured for agentic development and AI-assisted coding. The architecture includes strict typing, predictable patterns, and an Agents.md guide tailored for tools like Claude, Cursor, Gemini, and Grok. This allows AI copilots to safely generate features, refactor components, and extend the codebase while preserving architectural consistency — making vibecoding dramatically more effective.
Extensive Documentation
Step-by-step setup and deployment docs cover everything from authentication setup to common edge-case debugging like SHA mismatches, OAuth issues, and Google Sign-In failures.
Simple Expo Kit is a strong fit for solo builders, startups, agencies, and AI-native development teams that want to move fast without sacrificing production readiness. It provides a stable, preconfigured mobile foundation so developers can spend less time fighting setup and more time shipping features.
