PETINDER is a playful prototype that reimagines civic engagement by turning Luxembourg’s public petition platform into a swipeable, mobile-friendly experience.
Built during a hackathon, this project was also an experiment in coding with AI agents to evaluate how far we can go with minimal manual intervention.

♻️ Published re-use on data.public.lu.

• Fetches and displays live petitions from the Chambre des Députés via a reverse-engineered API
• Presents petitions in a Tinder-like UI for quick discovery
• Enables users to swipe through and engage with active petitions
• Uses localStorage to track interactions
• Parses and serves cleaned JSON data via Edge Functions

Public petitions are powerful civic tools—but let’s be honest, they’re buried in clunky interfaces, feel a bit stark, and struggle to reach younger audiences. I wanted to test if a Tinder-style interface, built fast and mostly by AI, could make democratic engagement feel natural, quick… even fun.

• 💅 Frontend Framework: Lovable.dev
  • Vite
  • TypeScript
  • React
  • shadcn-ui
  • Tailwind CSS
• 🧠 AI-driven development: 99% of the code was written by ChatGPT & GitHub Copilot
• ✍️ Manual edits: A few quick fixes made in the IDE
• 🌐 Data source: Unofficial API of the Chambre des Députés
• 🧾 Edge function: Parses raw JSON and serves cleaned petition data
• 💾 LocalStorage: Used to store swipe state without accounts or sessions

This wasn’t just about building a cool civic tech tool.
It was about testing what AI coding agents can accomplish in a high-pressure, short-timeframe environment like a hackathon — versus the more structured, collaborative pace of traditional dev work.

• ⏱️ ~2 hours to MVP
• 🤖 AI wrote almost everything
• 🧪 Experiment in AI-assisted software delivery

👉 Live Demo

• Swipe through petitions like you’re browsing a dating app
• Simple UI optimized for mobile
• Real-time(ish) data from the parliamentary site
• Easy way to “engage on impulse” — no account required

# Step 1: Clone the repository using the project's Git URL.
git clone https://github.com/clawfire/peti-swipe-lu.git

# Step 2: Navigate to the project directory.
cd peti-swipe-lu

# Step 3: Install the necessary dependencies.
npm i

# Step 4: Start the development server with auto-reloading and an instant preview.
npm run dev

• Some fields missing (e.g., petition deadline) from the open dataset, so JSON is taken from the website unofficial API, cleaned and stored manually via an edge function

All code is public. Fork it, remix it, or use it to build civic tech in your own country.

public money = public code
