Pen Tracker

PEN Tracker

A client-side Fabric mod built specifically for The PEN Server — rebuilt from the ground up for Season 3, with rank, prestige and rebirth progression, custom fishing, baking, drugs, sewers and vaults. PEN Tracker sits quietly in the corner of your screen and keeps track of everything that matters. It follows your progress, prices everything you're carrying to the cent, tracks your quests live, and never sends a command on its own.

Only useful on The PEN. Some prices come from an online service — see Data & online service below.

What it does

Progress tracking — your rank, prestige and rebirth are read automatically from the tab list. See the cost of your next rank, every rank left to Z, your next prestige and its token reward, and exactly how far your balance is from it. Prestige and rebirth tokens, cigs and tool power are all on screen too.

Exact sell values — fish, cookies, blocks and drugs are priced the way the server prices them, boosts included. If the server changes a price, your next sale corrects it automatically.

Mining overlay — see the sell value of everything in your inventory at Commissary prices, plus what's sitting in your vaults and backpack.

Money tracking — a rolling hourly total from every kind of sale: the sellall trader, AutoSell, fish, cookies, sewer kills and Auction House sales, plus cigs/hr from drug sales.

Fishing mode — counts and values the fish in your inventory, vaults and backpack, flags fish that aren't yours, and shows keys earned this session.

Cookie mode — tracks Baking Wheat, Baking Cocoa, Cookies and Super Cookies, shows how many batches you can make, and prices them for your hoe and progression.

Drug lab — shows the drugs you're holding and their value in cigs (raw and processed), your level on every lab upgrade with the next cost, and the cheapest upgrade to buy next.

Sewers — kills and money per hour while you grind, and exactly what the server pays per kill.

Quests — every NPC's quest, your progress and the reward. Run /quests once and it updates live as you bake, fish, mine, process drugs, chop, duel, level mcMMO, sit in the AFK room or carry hand-in items.

Vault & backpack browser — press V to open a full-size preview of all your vaults (or your backpack pages) without sending a single command. Browse freely, hover to inspect items, and use the pencil to open one on the server when you're ready. Contents are cached to disk and survive relogs. Bare /v and /bp reopen the last one you used.

PEN Tracker users in tab — players using PEN Tracker show with a gold name and ⛏ in your tab list while they're playing with it. You can opt out any time.

Vote opener — typing /vote opens all the voting sites in your browser with a short stagger between tabs.

Chat filtering — optional toggles to hide fish sell confirmations, vault open/close messages and server restriction messages, plus a Discord ignore list for relayed messages (staff can't be ignored).

Keybinds — assign keys to /d, /condense, /arm gui, /prestige, /bake, /minetop and /wb (Welcome Back). All unbound by default and visible in both the Controls screen and the ModMenu settings panel.

Data & online service

Some prices (fish, cookies, sewer pay and prestige costs) come from the PEN Tracker price service instead of being built into the mod. To use it, the mod signs in with your Minecraft account's chat-signing key — no password is ever sent. It sends:

• your Minecraft UUID
• the fish it needs priced (species and size)
• what your cookie and sewer prices depend on: rebirth, prestige, tool power, hoe enchants, mining and rebirth upgrades, and active money boost
• when you join and leave, so other PEN Tracker users can see the gold tab marker (turn off Show Me In Tab to opt out)

Nothing else is collected, and nothing is shared with anyone. If the service can't be reached, the mod keeps working with whatever it can still price.

Built for The PEN

Every price, every formula, every chat pattern is tuned specifically to The PEN's Season 3 economy. This isn't a general-purpose prison mod — it's built around one server and does that one job well.

Requires Fabric for 1.21.10 or 1.21.11 + Fabric API — Client-side only. Mod Menu recommended.
