Collection management that feels like magic.
Most trackers know what you own. Upkeep knows where it is — this binder, that box, sleeved into a deck — and that’s the difference between a number and an answer.
Filed.
Find anything
Know where everything is
Ask, and it answers: in Binder A, or sleeved into a deck, or that every copy you own is already spoken for.
Put a card on your want list and it goes further — it names which of your friends has a spare, and how many.
One honest rule
Sleeve it, and it's spoken for
A card filed in a deck stops counting as available everywhere else in the app — not because Upkeep hides it, but because it’s true. That one rule is what keeps every other number honest.

Wish list
Your friends already have what you're missing
Put a card on your want list and Upkeep checks your whole circle’s tradable binders for it — not just whether someone has it, but how many, and where.

Playtest
Know your odds before you shuffle up
Playtest simulates thousands of opening hands and mulligans against your actual decklist — not a hypothetical one — so you know your real keep rate before you ever draw a card at the table.
Keep rate, on the play
82%
1,000 simulated opening hands against this exact decklist, not a hypothetical one.
What it’s worth, honestly
Prices come from Scryfall’s daily export, TCGplayer-derived, and priced per finish — so a foil is never quietly valued as a non-foil.
A card with no price shows as unpriced, never zero — and the total says how many.
What it isn’t
Not a marketplace. Nothing to list, nothing to sell, no fees, no strangers. When you do want to buy a card, it hands you to TCGplayer and gets out of the way.
I’m building this for my own playgroup first, while Project Upkeep finds its feet.
