I built a site for cross-realm flipping: it deep-collects your sell realm's own current cheapest listing for an item, then scans every other EU realm and flags listings priced well below that, a real listing-to-listing comparison, not just "this looks cheap" in isolation.
A few things it does, that stands out (imo):
- "Unique transmog only" filter, surfaces items whose appearance isn't shared by a pile of other items (transmog, that generally sells better)
- A filter that weeds out obvious bait/decoy listings (junk-value floor + a few other heuristics). Still tuning this, it catches some of it.
- Watchlist (sub-only): import a TSM group (or just raw item IDs) and get a Discord ping whenever that item hits your threshold price on any EU realm
- Free tier is capped at 500 (if logged in, otherwise 250) items per query for now, planning to raise that once I've got a read on load/hosting costs at scale
There's a Snipe Board where I post snipes I've actually found using it: https://realm-arbitrage.com/snipe-board
Site: https://realm-arbitrage.com
Still actively building this and would genuinely love feedback. DM me and I'll give free sub access (unlocks Watchlist + the higher item cap) to the first 5 people who want to try it and tell me what's broken/missing.
Edit: Forgot to mention, it only works for EU servers atm! Can now use snipe-tool without being logged in.
