- Verdict: **Solid side project** (68/100 vibecodeable)
- Estimated effort: 2-3 weeks part-time

## Verdict

Build a responsive web-app clone with a Next.js frontend and an LLM scraping pipeline, though building native wrappers for all four desktop and mobile platforms will test your patience.

Replicating Paprika's native macOS, Windows, iOS, and Android apps as a solo builder is an exercise in multi-platform fatigue. Instead, build a single responsive web application (PWA) using Next.js that handles offline caching via local IndexedDB. The hardest part isn't the UI — it's writing robust parsing logic that turns chaotic recipe blogs into clean JSON ingredients. Using an LLM extraction pipeline bypasses endless custom CSS scrapers, but handling unit conversions (`1/2 cup` to grams) and ingredient merging logic requires meticulous string manipulation and testing.

### What you can't replicate

- Over a decade of custom parsing rules for thousands of weird recipe blog layouts
- The massive existing user base and 16-year operational trust

## What it does

A cross-platform recipe manager that extracts recipes from the web, scales servings, detects cooking timers, and syncs data across devices.

### Core features

- Web importing and LLM-based structured recipe parsing from arbitrary URLs
- Interactive cooking mode with screen-awake lock and ingredient check-off
- Automatic cooking timer detection in recipe directions
- Smart grocery lists with aisle sorting and ingredient merging (e.g. 1 egg + 2 eggs = 3 eggs)
- Dynamic serving size scaling and metric/imperial measurement conversion
- Monthly and weekly calendar meal planning
- Local-first database with optional cross-device cloud sync

## The business

### Pricing

- iOS App: $4.99 — One-time in-app purchase for full version
- Mac App: $19.99 — One-time desktop license
- Windows App: $29.99 — One-time desktop license

Founded 2010.
Team size: Micro-studio.

## The hard parts

- Parsing unpredictable HTML DOM layouts from thousands of distinct recipe blogs into clean structured fields
- Reliable natural language parsing of fractional units, quantities, and density conversions
- Building a local-first offline storage engine with conflict-free multi-device synchronization

## How to vibe code Paprika Recipe Manager

### Prerequisites

- Node.js (free): Required runtime for building and running the full-stack Next.js application.
- GitHub (free): Source code repository and deployment pipeline integration.
- Gemini API Key (free tier available): Provides low-cost, high-context LLM calls for parsing unstructured recipe web pages.

### Recommended AI tools

- Claude Code: Best-in-class terminal coding agent for scaffolding multi-file full-stack apps and writing complex parsing algorithms.
- Cursor: Ideal AI-native editor for refining UI components, interactive cooking mode screens, and grocery list sorting logic.

### Stack

- Frontend: Next.js with Tailwind CSS and shadcn/ui components
- Backend: Next.js Server Actions / API Routes
- Database: Turso (SQLite at the edge for local-first sync)
- Auth: better-auth
- Payments: None (personal use clone)
- Other: Gemini API for web recipe parsing, Vercel AI SDK for structured JSON extraction, PWA capabilities for offline mobile/tablet use

### Hosting

- Cloudflare (Hosting the Next.js frontend and edge API routes): $0/mo
- Turso (Serverless SQLite database for recipes, meal plans, and grocery items): $0/mo

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js project with Tailwind CSS, configure Turso SQLite connection, and define database schemas for recipes, ingredients, grocery lists, and meal plans.

```
Create a new Next.js project using App Router and Tailwind CSS. Configure Turso (libSQL) database client in lib/db.ts. Write migration scripts to create tables: 'recipes' (id, title, description, prep_time, cook_time, servings, image_url, instructions JSON, source_url), 'ingredients' (id, recipe_id, name, amount, unit, category), 'meal_plans' (id, date, meal_type, recipe_id), and 'grocery_items' (id, name, amount, unit, aisle, completed). Ensure proper foreign keys and indexes for fast retrieval.
```

2. **Authentication & Local-First Setup** — Integrate better-auth for secure single-user access and set up offline client caching so recipes remain accessible without an active internet connection.

```
Set up better-auth in the Next.js app with email/password credentials and session management. Implement a client-side IndexedDB caching layer using Dexie.js that mirrors the Turso SQLite tables, enabling offline recipe browsing and local grocery list modifications when disconnected from the network.
```

3. **Web Recipe Importer & LLM Extraction Pipeline** — Build a URL scraper endpoint that fetches target web pages, extracts raw text or JSON-LD schema, and calls the Gemini API to parse clean ingredients, steps, and metadata.

```
Implement a server-side route POST /api/recipes/import that accepts a recipe URL. Fetch the HTML using native fetch, strip out extraneous tags, and send the cleaned text to the Gemini API using Vercel AI SDK's generateObject. Define a strict Zod schema enforcing structured extraction for title, prepTime, cookTime, servings, ingredients (array of name, amount, unit, category), and instructions (array of step strings). Store the parsed result in the Turso database and return the created recipe ID.
```

4. **Interactive Cooking Mode & Timer Detection** — Create a dedicated cooking view with screen-awake persistence (NoSleep.js or Wake Lock API), interactive ingredient check-offs, step highlighting, and regex timer detection.

```
Build a responsive cooking view component at /recipes/[id]/cook. Implement the browser Wake Lock API to prevent the screen from sleeping while active. Render ingredients as interactive checklist items that strike through when clicked. Render instruction steps with click-to-highlight functionality. Write a utility function using regular expressions to scan instruction text for time patterns (e.g., 'bake for 35 minutes', 'simmer for 10-15 mins'), rendering them as clickable timer badges that launch an interactive countdown timer when tapped.
```

5. **Smart Grocery Lists & Aisle Sorting** — Implement grocery list generation from recipes, automatic unit-aware ingredient merging (e.g., 1 egg + 2 eggs = 3 eggs), and supermarket aisle categorization.

```
Build a grocery list management module. Implement an aggregation algorithm that takes selected recipes, extracts their ingredients, matches similar ingredient names and units, and automatically sums quantities (e.g., combining '1 large egg' and '2 eggs' into '3 eggs'). Automatically assign items to supermarket aisles (Produce, Dairy, Pantry, Meat) based on a categorized ingredient dictionary, and allow users to manually reorder or check off items.
```

6. **Serving Scaling, Measurement Conversion & Meal Planner** — Add dynamic scaling for ingredient quantities, metric/imperial unit conversion toggles, and a calendar view for daily/weekly meal planning.

```
Add scaling and unit conversion controls to the recipe detail view. Implement a multiplier function that recalculates ingredient amounts proportionally when the user changes the target serving size. Add a toggle to convert volume and weight measurements between metric (grams, ml) and imperial (cups, ounces). Finally, build a monthly/weekly calendar view at /meal-planner that allows dragging or assigning recipes to specific calendar days and meal slots.
```
