The problem AppLighter solves

AI coding agents have changed what's hard about shipping a mobile app. A year ago the bottleneck was writing the code — Claude Code, Codex, Cursor, and Windsurf collapsed that overnight. The new bottleneck is what the agent is writing on top of. Vibe-code an app from scratch and you get the agent's confident best guess at architecture, design, and security: leaking API keys, hallucinated schemas, generic AI-shaped UI, RLS policies that don't exist, and a codebase that fights you the second it grows past the first feature.

AppLighter is the foundation that fixes this. Eighteen full-stack React Native + Expo templates, each one designed as a foundation your agent can extend without breaking.

What's in the catalog

Eighteen production-shaped templates covering taxi booking, fitness, e-learning, food delivery, real estate, AI travel planner, AI calorie counter, period tracker, chat and messaging, short video social, multi-vendor ecommerce, all-in-one marketplace, restaurant reservation, fashion store, grocery delivery, bus ticket booking, pet care and tracker, and weather. Free template available for evaluation. Paid templates from $49 to $149.

How each template is built

Senior React Native engineers architected each template — typed contracts, semantic file paths, isolated domain layers. Senior product designers pixel-perfected every screen with design tokens, motion curves, typographic hierarchy, and full light and dark themes. Security review happened before release: RLS policies on every table reviewed line by line, every secret wrapped in an edge function, zero API keys in client bundles, auth flows penetration-tested, edge endpoints rate-limited.

Why your agent works better here

Every template ships agent-readable. Each repo has CLAUDE.md, AGENTS.md, and .cursorrules pre-committed, plus a documented architecture map and typed contracts at every API boundary. On top of that, six slash commands handle the work agents do over and over: /add-screen scaffolds new screens with design tokens wired up, /add-provider plugs in a new auth or payment provider behind the existing abstraction, /swap-backend migrates from Supabase to Drizzle or Neon without touching app code, /audit-security runs the security checklist locally, /rebrand walks the agent through tokens, logos, splash, and app icon, and /ship builds and submits to the App Store and Play Store with the right env and metadata.

The stack

React Native, Expo SDK 54, TypeScript, NativeWind, Reanimated, Expo Router. Backend on Vibecode DB — Supabase by default, with adapters for Drizzle and Neon. AI layer is bring-your-own-key, provider-agnostic, with streaming and tool use built in. Works first-class with Claude Code, Codex, OpenCode, Cursor, and Windsurf.

Who built it

Architected by Sanket Sahu — creator of NativeBase (~25k GitHub stars), gluestack, and founder of GeekyAnts. Roughly fourteen years of React Native delivery behind every decision in the codebase. Every architecture choice in AppLighter comes from patterns that survived production. The ones that didn't became the things we deliberately avoid.

About AppLighter

What is AppLighter?

AppLighter is a collection of 18 production-ready React Native + Expo templates designed specifically for the AI agent era. Instead of forcing AI coding agents to build apps from scratch—which often results in leaking API keys, hallucinated schemas, and fragile codebases—AppLighter provides hand-crafted foundations that agents can extend without breaking. Each template ships with pre-installed slash commands, agent configuration files, and security-reviewed code so your AI assistant works with a solid architecture from the start.

Who it's for

Indie founders who want to ship a mobile app fast using AI agents but need a reliable foundation that won't collapse after the first feature
Agency teams building multiple client apps who need consistent, secure templates their agents can extend without manual rework
Senior developers who know React Native but want to skip the weeks of architecture, design, and security setup so their AI can focus on the unique business logic

Key features

Agent-ready configuration files

Every AppLighter template ships with CLAUDE.md, AGENTS.md, and .cursorrules pre-committed, plus a documented architecture map and typed contracts at every API boundary. Your AI agent understands the codebase structure immediately, eliminating the guesswork that slows down vibe-coding sessions.

Six slash commands for common workflows

Six built-in slash commands handle repetitive agent tasks: /add-screen scaffolds new screens with design tokens wired up, /add-provider plugs in auth or payment providers behind existing abstractions, /swap-backend migrates from Supabase to Drizzle or Neon without touching app code, /audit-security runs the security checklist locally, /rebrand walks the agent through tokens and app icons, and /ship builds and submits to app stores with correct environment variables.

Security-reviewed architecture

Senior engineers architected each template with typed contracts, semantic file paths, and isolated domain layers. Security review happened before release: RLS policies on every table reviewed line by line, every secret wrapped in an edge function, zero API keys in client bundles, auth flows penetration-tested, and edge endpoints rate-limited.

Designer-vetted UI with full theming

Senior product designers pixel-perfected every screen with consistent design tokens, motion curves using Reanimated, typographic hierarchy, and complete light and dark themes. Your agent inherits taste—not generic AI-shaped UI or Tailwind soup.

What stands out

"Code generation is the cheap part. Architecture, design, and security are still measured in weeks. We made those decisions. Your agent does the rest."

This captures AppLighter's core insight: AI coding agents have collapsed the cost of writing code, but they still struggle with architecture, design, and security. AppLighter solves this by providing battle-tested foundations where those hard decisions are already made. Your agent extends a production-ready structure instead of hallucinating one from scratch.

Worth checking out if…

You're building a mobile app with AI coding agents and want to skip the weeks of architecture, design, and security setup. AppLighter is especially valuable if you're tired of agents generating leaking API keys, broken RLS policies, or codebases that fight you after the first feature. With one-time pricing from $49 to $149, lifetime updates, and a seven-day refund, it's a low-risk way to give your agent a foundation that actually ships.
