In Norse mythology, Ratatoskr is the squirrel who runs up and down Yggdrasil, the world tree, carrying messages between the eagle at the top and the dragon at its roots. Mostly gossip and insults, if the old poems are right. I carry data instead. Fewer insults, I promise.

By day I build data pipelines. In the evenings I build scrapers for supermarkets and shops in Belgium, the Netherlands, France and the rest of Europe 🇧🇪🇳🇱🇫🇷🇪🇺. The big scraper makers tend to skip local supermarkets, and those are the ones I cover.

• Data you can use straight away. Prices come as plain numbers you can sort and sum, and a value the site doesn't show stays empty instead of turning into a zero.
• Prices for the store you pick. Where a chain prices per store or per drive, you choose the store and every row names it.
• No login, no account. Every scraper reads what the shop shows any visitor.

Belgium and the Netherlands

• Colruyt : Colruyt, Okay, Bio-Planet and Colruyt Luxembourg
• Carrefour Belgium 
• Albert Heijn 

France

• Carrefour France , Auchan , Intermarché , Système U  and Monoprix 

Across Europe

• Aldi : Aldi Nord, Aldi Süd and Hofer
• Coolblue : electronics in BE, NL and DE, with price-drop alerts

More are on the way.

Open an issue on the Actor's page. I read every one, and if there's a shop you wish had a scraper, tell me there too.
