Products
Eight products, all digital, all delivered by email. Every listing names the runtime it was tested on and the free tier it deploys to. Nothing here needs a subscription to keep running.
Monitoring and alert kits
A scheduled job that runs on a free tier and messages you when something changes.
Page Change Monitor
Watches a list of URLs on a schedule and alerts you when the content changes. Fingerprints the body, ignores whitespace and timestamps, keeps a history so you can see what changed.
- Runs on a free scheduled-worker tier
- Change fingerprint stored in KV
- Alert by email or chat webhook
- Source: JavaScript, single file
Price and Stock Watcher
Tracks a product page for a price drop or a return to stock. Parses the value you point it at, compares against the last reading, and only alerts on a real move.
- Numeric threshold and percentage rules
- Per-target cooldown so it cannot spam
- History kept for 30 days
- Source: JavaScript, single file

- Source: JavaScript, single file
