About

What this is

Two sites, one database. The pipeline visits all tracked shops daily, records every price and stock change, and notices what appears and what disappears. AllTinned is the reference built on top: brands, species, regions, preparations, guides, every page open and indexable. MrTinned is the market layer: live prices with history behind them, restocks, deals, and a weekly report on what the data actually shows.

Who makes it

I'm Alex. I started this in 2026, standing in front of tins and wondering whether the price was fair, with nothing to tell me. The database runs the only way one person can run something this size, heavily automated. The pipeline collects. I direct software and AI to do much of the checking and drafting, then verify it myself, so I can answer for it. Nothing publishes that I haven't read. Every claim traces back to the database. When something is wrong, there's a person who fixes it, that's me. This project is not finished and never quite will be. The record gets corrected, refined, and expanded every week.

How the data works

Prices and stock come from the retailers' own product pages, collected daily. Every change is kept as history, which is what makes the price verdicts and the weekly rulings possible. Records are reconciled before they are believed: a listing that vanishes gets checked before it is declared gone, duplicates get merged, and a certification only stands if the source page supports it. Automated collection still produces errors, gaps, and stale entries; the report errors link on every page reaches a person, and fixes happen quickly.

Independence

No retailer or brand owns any part of this. Coverage is never for sale, entries are never for sale. Clearly labeled placements help fund the free reference; they buy position, not opinion.
