AI early warning system for developers. Free, open source, runs entirely on GitHub.

The Problem

Developers building on AI APIs depend on providers that change pricing, deprecate models, modify rate limits, and shift terms — often without clear notice. Staying informed means manually checking 10+ sites daily. Most devs miss critical changes until something breaks in production.

The Solution

An automated monitoring tool that scrapes official AI sources daily, uses an LLM to filter and extract structured metadata, detects changes in critical provider pages, and serves this dashboard + an RSS feed. Zero cost. Runs entirely on GitHub infrastructure with one free API key.

How It Works

A GitHub Actions cron job runs this pipeline daily at 8:00 UTC. Data is committed back to the repo, and the dashboard is deployed to GitHub Pages automatically.

What It Monitors

News feeds (8 sources):

Provider pages (diff detection for changes):

Two Layers of Value

• Alerts — what you need: deprecations, pricing changes, breaking API changes. Shown with red accents and high impact badges.
• Updates — what you want: new models, tools, releases, features. The news that keeps you ahead.

Quick Start (Your Own Instance)

1. Fork the repo on GitHub
2. Add your GOOGLE_API_KEY in Settings → Secrets (free from Google AI Studio)
3. Enable workflows in the Actions tab
4. Enable GitHub Pages from the gh-pages branch
5. Done — your dashboard appears at https://<user>.github.io/modelsentry/
