Furnace Helper
by Ragek34
Furnace Helper is a client-side Fabric mod for 1.21.1 that tracks furnaces, blast furnaces and smokers and reports when their items are ready.
What it does
Opening a furnace or smoker shows a prediction of how many items will be finished, using a calculation that accounts for the current smelting progress. Players can check a status readout without staring at the block, so they can leave the station, go gather resources or build, and come back when the batch is done.
The mod is aimed at players running several smelting stations at once, such as furnaces for ores, blast furnaces for metal and smokers for food. It is also meant to work alongside Furnaces Classic, Smokers Chefs and Blast Furnaces Grinders, so the setup covers all three station types.
Furnace Helper has no server component, so only the client needs it. It requires Fabric to load and is published for 1.21.1 under the MIT License, which is not an open source license.
Key features
Furnace Math Helper
A calculation estimates the exact number of items each furnace or smoker will finish, updated as smelting proceeds.
Real-time prediction
The predicted count of finished items updates while the station is working, rather than only when it is opened.
Status check
A quick status view shows which stations are still running and which have finished their batches.
Low resource use
The code is tuned to keep the frame rate steady while many furnaces are smelting at the same time.

Use cases
Long smelting runs
A player starts a large batch of ores or steak and leaves the base, then checks the predicted counts on return.
Multi-station bases
Players with rows of furnaces, smokers and blast furnaces can keep track of every station from one view.
Who it’s for: Players who run many smelting stations in survival or creative worlds and want to see progress without opening each block. It suits single-player and multiplayer clients alike, since only the client side is involved.
How it compares
Hotbar Helper is a client-side Fabric mod for 1.21 – 1.21.11, released under the CC0 1.0 Universal license and open source. Route Helper is also client-side and Fabric-only but targets 1.21.11 alone and is released under the MIT License, not as open source. Smelter The Hedgehog works on Fabric for 1.20 – 26.3, is server-side only and uses a custom license, so it runs on the server while Furnace Helper runs on the player's client.
