The verdict: can you vibe code Lensa?
Build a web-based proof-of-concept wrapper around an open-source image generation API, but keep paying for the mobile app if you want native performance and polished camera pipelines.
Replicating Lensa's core value as a personal tool means building a cross-platform mobile app that interfaces with a GPU backend to run Stable Diffusion fine-tuning and image segmentation models. While you can stitch together React Native, fal.ai, and Expo in a few weeks, handling the asynchronous queue for Magic Avatars, mobile touch-gesture performance, and managing API costs requires real engineering grit. It's a serious undertaking that will consume weeks of frustrating debugging.
Estimated effort: 4-6 weeks of part-time development
What you can't replicate
- Lensa's viral user acquisition loops and celebrity endorsements
- The massive proprietary dataset of fine-tuned portrait models and specialized weights
- App Store featured placement and frictionless mobile billing integration

Build guide
01Project Scaffolding & Mobile Shell
Initialize a React Native app using Expo Router with file-based navigation, setting up standard tabs for editing, magic avatars, and user account management.
Initialize a new Expo React Native project using TypeScript and Expo Router. Set up a bottom tab navigation bar with three primary tabs: 'Editor', 'Magic Avatars', and 'Profile'. Configure safe area views, a dark-mode theme by default, and install lucide-react-native for icons. Ensure the folder structure separates components, hooks, services, and app screens cleanly. Write a smoke test or basic screen render test to verify the setup.02Photo Picker & Basic Local Editor UI
Implement image picking from the device library, canvas preview area, and filter parameter sliders for contrast, saturation, and blur effects.
Implement an image picker screen using expo-image-picker that allows users to select a photo from their camera roll. Display the selected image inside a scrollable, zoomable canvas component using react-native-reanimated and gesture-handler. Add a bottom drawer with horizontal sliders for adjustment parameters: brightness, contrast, saturation, and background blur intensity. Store the adjustment state locally in React context and display immediate feedback on the canvas state.03Backend API & Cloud Storage Integration
Build an Express backend service connected to Turso and Cloudflare R2 to handle image uploads and store editing sessions.
Create a Node.js and Express backend service connected to Turso (SQLite) via libSQL. Set up an endpoint for uploading user photos via multipart/form-data directly to Cloudflare R2 using AWS SDK S3 compatibility. Store image metadata, user IDs, and timestamps in a 'photos' table. Implement proper error handling, upload size limits (10MB), and return signed URLs for frontend display.04AI Magic Avatars Pipeline Integration
Integrate fal.ai APIs on the backend to accept a batch of selfie uploads, trigger generation tasks, and manage asynchronous status updates.
Build an asynchronous backend job queue using Express and Redis (or Upstash) that accepts a batch of 10-20 user selfies from the mobile app, uploads them to secure storage, and initiates an avatar generation pipeline via fal.ai. Create database tables for 'avatar_jobs' tracking status ('pending', 'processing', 'completed', 'failed'). Implement webhook endpoints to receive completion callbacks from fal.ai, update job status, and notify the user when their custom digital avatars are ready for download.05Avatar Gallery & Result Display Screen
Build a masonry grid view in the mobile app to display generated avatars with download and share actions.
Create a React Native screen for the 'Magic Avatars' feature that polls the backend or listens to job statuses. When a job is completed, fetch and render the generated avatar images in a responsive grid layout using a masonry list component. Add a detail modal when tapping an individual avatar with options to save to the device photo library using expo-media-library or share via the native share sheet.06Subscription & In-App Purchase Stubbing
Integrate RevenueCat SDK into the mobile app to handle subscription checks, feature gating, and paywall popups.
Integrate RevenueCat into the Expo React Native app to manage subscription entitlements for Pro features and Magic Avatar packs. Create a reusable Paywall modal component that displays subscription tiers, feature comparison lists, and purchase action buttons. Gate advanced filters and avatar creation behind active entitlement checks, gracefully falling back to free-tier restrictions when entitlements are missing.
