The free multi-store price tracker with price drop alerts
Track one product across several online stores. PriceSentinel checks the prices on a schedule, keeps the price history and alerts you on Discord, Slack, Telegram, ntfy or a webhook when the price drops or another store becomes the cheapest.
How it works
From a product link to a price drop alert in four steps
Add a product
Paste its links from up to 3 stores, or press Research with AI from the Add button and pick the stores it finds.
Get a base price
The first price captured becomes the base price. Every later price is compared with it, and the cheapest in-stock store becomes the best price.
Prices are checked on schedule
As often as every 6 hours, with retries, back-off and polite delays per store. The history is kept for every link.
You get the alert
When a store becomes the cheapest, a price reaches your target or falls below the base price, the alert reaches your channels.
Features
Everything you need to watch a price
One place for the products you want to buy, the stores that sell them and the moment the price is right.
Multi-store tracking
Attach links from several shops to one product. The cheapest in-stock store is always shown as the best price.
Price drop alerts
Get notified when a store becomes the cheapest, a price hits your target or drops a set percentage below the base price.
Price history charts
A chart for every store, the 30-day average and low, the all-time low and how much you save against the base price.
Smart price extraction
Store adapters, schema.org data and price heuristics read the real price and stock, not the crossed-out one.
AI link research
Type a product name and the AI finds stores that sell the exact same product, with the price read from each page.
Multi-currency
Prices from stores in other currencies are converted into your product’s currency with daily ECB exchange rates.
AI link research
Find every store that sells it
Type the product you want. The AI plans search queries, PriceSentinel opens every result, reads the real price and checks that it is the exact same product, not a lookalike. You tick the stores to track.
Then ask the AI assistant things like what dropped this week?

FAQ
Common questions
Is the hosted price tracker really free?
Yes. There is no paid plan, no credit card and no ads. To keep the shared server fair for everyone, free accounts have limits: 25 products, up to 3 store links per product and price checks at most every 6 hours. AI features use your own API key, so their cost is billed by your AI provider, not by PriceSentinel.
Do I need an AI API key?
No. Tracking, price extraction and alerts work without AI. A key is only needed for AI link research, the AI assistant and the AI fallback that reads prices from difficult pages. Supported providers are Anthropic, OpenAI, OpenRouter, Groq, Google Gemini (through its OpenAI-compatible endpoint), Mistral, DeepSeek and any other OpenAI-compatible endpoint.
Which online stores are supported?
Any store with a public product page. Built-in adapters cover Amazon, eMAG, eBay, Altex/Media Galaxy, cel.ro, PC Garage, evoMAG and a few others. Every other shop goes through a generic pipeline that reads schema.org data, product meta tags and price heuristics. If a page still cannot be read, an AI model with your own key can extract the price as a last resort. Some shops block automated requests; those may not work.
Can I run PriceSentinel on my own server instead?
Yes. It is open source under the MIT license and runs with Docker Compose, from source with Node.js or as a desktop app. Self-hosted installs have no limits and add email alerts, Gotify, the MCP server and local AI models. See the self-hosting guide.
