Listings for this item
⚠ Delist Queue
These listings are still live on other platforms for items that already sold. A live duplicate can sell twice. Take each one down on its platform, then confirm it here.
Data
Import
Bring in a Lister backup (restores everything) or an items file (adds items). Files are integrity-checked before anything is touched; a file that fails its check is refused and your data is left exactly as it was.
Export
Your whole dataset, in one sealed JSON file you own.
About
Lister is a cross-platform listing manager: one product, every platform it's listed on, what state each listing is in — and a delist guard so nothing sells twice.
Your data lives on this device. There is no account, no subscription, and no upload — and it leaves only in a file you export.
Lister never contacts a marketplace: no sign-ins, no fetching, no scraping. You post; it prepares, tracks, and guards. Listings on closed platforms are always posted by you, by hand.
Surfaces
Where Lister makes sense, where it doesn't, and what's queued — the Meta surfaces matrix (SURFACES.md, sweep 2026-10-22), rendered from the app's own data. A row claims only what the sweep graded.
Danger zone
Erase everything stored in this app on this device. Export a backup first if you want it back.
⚠ Saved data failed its integrity check
The data stored on this device does not match its checksum, so Lister will not open or overwrite it — it may be damaged, or something changed it. Nothing has been altered.
You can download the stored data exactly as found (for inspection), or erase it and start empty.
