What shipped, when it shipped, and what broke.

Slabbist is in closed beta with a handful of stores. Here is everything that has gone out — what is working, what got fixed, and what is still in flight.

2026-06-07·v0.10.0Closed beta

Pre-grade, movers, and grade gains

  • Pre-grade: estimate the PSA-equivalent grade on-device with centering, corners, edges, and surface sub-grades.
  • Centering tool with snap-to-edge guides and live left/right and top/bottom ratios.
  • Movers: top gainers and losers by set and price tier, English or Japanese.
  • Grade gains: see how much profit you could make grading a raw card to PSA 10, with a live grading-fee stepper.
  • There is also something hidden in here. We are not going to tell you where.

Lots, offers, and the transaction ledger

  • Group scans into a lot, present an offer, and mark it paid with a payment method and reference number.
  • Paid lots lock and move into a permanent transaction ledger. You can void one with a reason if you need to.
  • Vendor registry with contact details and notes, attachable to any lot.

TAG grading support

  • The camera now reads cert numbers on TAG-graded slabs alongside PSA, BGS, CGC, and SGC.
  • Confidence scoring now accounts for comp volume and price spread per grade.
  • Fixed a sync stall when a queued scan had no cert number.

Margin ladder

  • Set a buy percentage for each price tier. Each slab prices against its comp at the highest tier it clears.
