DevPulse

The problem

Keeping up with developer news means checking Hacker News, Dev.to, Lobsters, GitHub Trending and AI news one site at a time, then reading long articles to find out whether they matter.

What I built

DevPulse puts those sources into one reader. Any story can get an instant AI summary, and the app can turn top stories into short generated articles.

• One feed across five sources, with source filters.
• On-demand AI summaries and trend analysis.
• A scheduled job that runs every six hours, finds top stories that have not been covered yet, and generates articles for them.
• Installable as a web app, with a service worker.

How it works

• No framework on the front end. Plain HTML, CSS and JavaScript talk to /api/* routes that Netlify maps to serverless functions, one per source plus summarise, generate, articles and status.
• An AI router built for free tiers. The summarise function rotates across Gemini models and several API keys, tracks a per-key request budget with a cooldown after rate-limit errors, and falls back to Groq-hosted Llama models. Responses are cached for an hour.
• Storage without a database. Generated articles live in Netlify Blobs, which keeps the backend serverless.
