What is Pricely?

Pricely is a price comparison tool that gathers product data from various companies. Its purpose is to show you the most accurate prices, free from ads and tracking. Pricely is fair and independent of specific companies.

How to search in Pricely.dk?

You will need to input your own API or a public one hosted by someone else. I am not responsible for what data you send to Pricely and I am not hosting the PricelyAPI Project found on this repository anywhere on the web.

What does it do?

No Tracking

Pricely retrieves product data without trackers, allowing search freely without being tracked. All data is fetched on the server and passed to the client, meaning no tracking from services like Klarna, Google, Adform, Facebook, TikTok, etc.

Environment Variables
