Track prices from the stores you actually use. Run it yourself. Keep the data. Know when a deal is real.
PriceBuddy is an open source, self-hostable price tracker for people who would rather watch products than browser tabs. Paste in a product URL, let PriceBuddy check it on a schedule, and get notified when the price or availability moves in your favour.
It works across different stores, keeps price history, compares listings, handles stock status, and can use your own AI provider when a page is awkward to scrape. The web app is the main control room; the API and CLI make it scriptable.

Most price trackers work only where someone has already built an integration. PriceBuddy is built for the messy web: normal product pages, changing markup, multiple listings for the same item, stores that go in and out of stock, and the usual "sale" prices that are not really sales.
Use it for everyday shopping, household wishlists, hobby gear, computer parts, baby stuff, subscriptions, marketplace listings, or anything else where timing matters.
Paste a product URL and PriceBuddy will try to read the product title, image, price and availability. Many stores work straight away. For trickier sites, you can tune the scrape strategy without changing code.
Track the same product across multiple stores, or multiple listings on the same marketplace, and see the current best option in one place.
PriceBuddy records prices over time so you can see highs, lows and trends. That makes it easier to spot fake discounts and decide whether today's price is actually good.
Set a target price or percentage drop and let PriceBuddy watch for it. Notifications can go through the app, email, Pushover, Gotify, Apprise, Telegram, Discord or ntfy.
A cheap listing is useless if it is out of stock. PriceBuddy tracks in stock, pre-order, back order, special order, out of stock and discontinued states.
PriceBuddy can calculate price per unit, so a 10-pack and a 3-pack can be compared fairly.
Bring your own OpenAI, Anthropic, Gemini or local Ollama provider. PriceBuddy can use AI to recover missing data from a page or help repair scraping rules. It is optional and off by default.
Connect a SearXNG instance and search for products from inside PriceBuddy.
Use tags, filters and multi-user accounts so each person can track their own products, targets and notification preferences.
Run PriceBuddy on your own server with Docker. Your watchlist, price history and notification settings stay under your control.
PriceBuddy is designed to be useful from more than the web UI. The tool ecosystem is small for now, with more planned.
| Tool | What it is for |
|---|---|
| PriceBuddy CLI | Command-line access for humans and agents. Sync a local mirror, search products, inspect price history, run deal/drop reports, call the REST API, and expose PriceBuddy through MCP. |
A browser extension is planned.

All you need is Docker.
Download docker-compose.yml, adjust it for your environment, then start PriceBuddy:
touch .env
docker compose up -dWith the defaults, the app runs at http://localhost:8080.
Default login:
admin@example.com / admin
Change that password immediately.
See the installation guide for the full setup and configuration options.
Docker is the recommended install path. If you want to run it another way,
docker/php.dockerfileanddocker-compose.ymlare the best references for the required services and PHP extensions.
The Docker image includes the scheduler needed for background work: checking prices, updating history and sending notifications. You do not need to run a separate cron container.
Most settings live in the app. Advanced options can be set in .env.
See the settings docs for details.
PriceBuddy adds affiliate codes for a small number of stores to help support development.
If you do not want that, set this in .env or docker-compose.yml:
AFFILIATE_ENABLED=falseIf you disable affiliate support and still want to help, see supporting the project.
PriceBuddy was inspired by Discount Bandit. PriceBuddy's main difference is flexibility: it aims to track products from arbitrary stores without requiring a code change for each retailer.
Contributions are welcome. Open an issue or pull request if you have a bug fix, store compatibility improvement, documentation change or feature idea.
