Skyblock Companion

Highlights

• Premium market feed. The server-collected market feed (fresh Auction House sales, flip stability, daily price history and the selling advice built on them) is now available to invited players. Everyone else gets market data from SkyCofl automatically, with no setup needed. Premium players see Market Planner+ in the planner title.
• Premium screen. Tools → Premium (or mod settings → Credits → Premium) shows whether your account is premium, has a Check again button, and explains how to reach me about access.
• Advanced trading tools for everyone. The session planner, strategy lab, inventory crafts, item costs and execution tools no longer need a launch flag. You can remove -Dsbc.advancedMarket=true from your launch arguments.

Fixes

• The planner no longer shows a "SkyCofl fallback" status label.

Notes

• Requires Minecraft 26.2 and Java 25, with Fabric API, Dandelion, YACL, Hypixel Mod API, Skyblocker and SkyHanni (unchanged from the previous beta).
• Only the server feed is premium. Recipes, unlock checks, the planner's logic and all tools work for everyone.
• Premium is checked with Minecraft's own sign-in handshake, the same one servers use. Your access token is only sent to Mojang, never to the SkyBlock Companion server.
