Sub-200ms auction house monitoring for Hypixel Skyblock and DonutSMP. Catch underpriced BINs the instant they list — no manual scanning, no missed flips.
Polls the Hypixel API and DonutSMP AH on the fastest available cycle. New listings are scored against rolling median prices within milliseconds.
Every listing shows net profit after the 1% Hypixel AH fee. No mental math — just the number that actually lands in your purse.
Target specific items or categories. Set a minimum profit floor. Filter by server, rarity, or discount depth — only see the flips worth taking.
Full DonutSMP economy tracking in the same feed as Hypixel. DonutSMP's smaller player count means listings sit longer — easier to snipe.
Webhook and browser push when a watched item drops below your threshold. Set filters once, get pinged when the flip is ready.
Rolling median, low, and high for every tracked item. Know whether a listing is a genuine undercut or a price that's been crashing.
Star any item to pin it, then flip to the Watched view. Filters, sort order, and layout preferences persist between sessions.
Audible ping on new listings, compact rows for cramming more on screen, pause switch when the feed gets loud, and a configurable profit floor.
Found a Hyperion listed 34% under median at 2:14am and had it before the listing ticked over. +612M on one flip. I've been manually refreshing the AH for two years like an idiot.
DonutSMP listings sit for 10–30 seconds and this catches all of them. Went from 3M/hr to 28M/hr in the first week just running the 20M+ filter. Small server, big edge.
The tax maths is the part nobody else does right. Every other tracker shows gross profit and you find out about the 1% after you've already clicked. This one shows what actually lands.
One feed for both servers is the whole sell. I keep Hypixel on a second monitor and DonutSMP on the main, one Discord webhook fires for the good ones. Zero setup beyond the installer.
Runs for six hours straight without eating my frames — my old tool turned a 240fps client into a slideshow. Only knocking a star because I'd like mobile alerts when I'm away from the PC.
Started with the 5M+ filter because my purse was a joke. Three days later the threshold paid for itself twice over. The watchlist is what keeps me on it — pin the books, ignore the rest.
AH sniping is buying items listed significantly below market value before anyone else sees them. The Hypixel AH refreshes every 60 seconds — an underpriced legendary pet gets bought in under 3 seconds of going live at peak hours. AHSniper.net keeps you on that window with sub-200ms detection.
DonutSMP has a thriving AH economy with less competition than Hypixel's massive player base. Underpriced listings sit longer — 10–30 seconds instead of 2–3. Our DonutSMP AH tracker flags items listed 20%+ below the rolling median and surfaces them in the same feed as Hypixel.
High-margin flip targets: Necron armour pieces (Leggings, Chestplate, Boots), Hyperion, Juju Shortbow, Legendary pets (Ender Dragon, Griffon, Black Cat), enchanted books (Ferocity, Ultimate Wise, Giant Killer), Divan armour. Beginners: enchanted books and Rare pets for consistent 2–8M margins with low risk.
Know your median. Set a minimum profit filter (20M+ for experienced flippers, 5M+ for beginners). Act within 2 seconds of an alert — the best flips are gone in under 5. Always factor the 1% AH tax. On DonutSMP, 10–30M/hr is achievable with active flipping on a healthy economy cycle.
