price-tracker: price and stock monitoring for any online store

[](https://github.com/OfficialSpicrawl/price-tracker/actions/workflows/test.yml) [Live demo](https://price-tracker.spicrawl.com) · [Demo video (MP4)](videos/out/price-tracker/v1/price-tracker.mp4) · Apache-2.0


Open-source **price tracker** and **stock monitor**: point it at product pages on Shopify and most e-commerce stores, read the price from the page's JSON-LD / OpenGraph data (no selectors needed), and get **Discord or Slack alerts** on price drops, target prices and restocks. Run it from cron or **GitHub Actions**, or as a **Claude Code / Codex agent skill** for AI agents.

**Install as an agent skill** (Claude Code, Codex, Cursor and more): `npx skills add OfficialSpicrawl/price-tracker`, then run `npm install` in the installed folder. Or clone it and run it yourself:

Watches product pages and tells you when a price drops, falls to your target, or an item comes back in stock. It uses the [Spicrawl](https://docs.spicrawl.com) web scraping API through [`@spicrawl/sdk`](https://github.com/OfficialSpicrawl/sdk), in one file (`track.mjs`) with no build step.

It alerts when:

• the price is lower than the last check,
• the price is at or below the target you set (once, when it first gets there),
• an item goes from out of stock to in stock.

The first check of a product is the baseline: no drop or stock alerts. A target alert still fires if the price is already at or below it.
