I jumped into Railway Hackathon 2025 and built "rundown" — an AI-powered RSS reader that keeps an eye on your feeds, auto-summarizes new content, and pings you when something fresh drops. Here’s a quick tour of what it does, how it’s built, and what it was like to make it all happen on Railway.
The app is live on Railway at https://rundown.sbox.studio (not sure how long I’ll keep it up after the hackathon 🥴).

✨ Key Features
📚 1. RSS Feed Registration & Management
Add as many RSS feeds as you like and manage them all in one place.
🔍 2. Update Detection + AI Summarization
Every 15 minutes, it scans your feeds, finds the new stuff, and summarizes it using gpt-5-nano. Multi-language & adjustable length support included.
🗓 3. Timeline View
See all your summarized articles in chronological order, with easy browsing of past updates.
🔔 4. Discord Webhook Notifications
Get instant updates in your Discord channels — perfect for teams or communities.
🔗 5. MCP Integration
Hook it into your own tools and grab feed/article data programmatically.
You can connect to the MCP server running at rundown.sbox.studio/mcp using an API key generated from the settings page.
The MCP server is built with Vercel’s mcp-handler

💡 Takeaways
Railway made the whole multi-service setup ridiculously smooth — from creating services to managing env vars and logs. It’s a great fit for hackathons where you want to focus on building, not fighting your infrastructure.
Next steps? More notification channels and fancier diff analysis.
