Aillio Bullet software: RoasTime, Artisan, and Rostoc.
Aillio Bullet owners usually compare three software paths: RoasTime, Artisan, and a roastery operations tool such as Rostoc. The right choice depends on whether you need native Bullet operation, configurable technical logging, or inventory-connected production records.

Direct Answer
RoasTime is the native Aillio Bullet software and should remain the starting point for Bullet-specific operation and Aillio ecosystem workflows. Artisan is a flexible roast logger for users who want detailed setup control. Rostoc is a fit when the Bullet roast should connect to green inventory, plans, batches, notes, and production history.
For Rostoc, treat Aillio support as experimental read-only USB logging until you validate readings and saved records on your exact Bullet model.
Quick comparison
The search question behind Aillio Bullet software is usually not just which app can draw a curve. It is which app should own the roast, the machine-specific workflow, and the operational record after the roast ends.
| Software | Best fit | Rostoc note |
|---|---|---|
| RoasTime | Native Bullet operation, recipes, logging, analysis, automation, and Roast.World workflows. | Keep it as the native reference while validating Rostoc. |
| Artisan | Configurable technical logging for users comfortable with machine setup details. | Useful as setup evidence, especially when a team already has Artisan files. |
| Rostoc | Inventory-connected roast records, plans, batches, green lots, and production history. | Experimental read-only USB support for selected Bullet entries. |
When Rostoc is the right addition
Rostoc is strongest when the roast record needs to answer operational questions after the curve is drawn. Which green lot did this roast consume? Which plan was used? Which batch did the team produce? Which notes and quality decisions should be available next time?
That is why Rostoc can be useful even when RoasTime is already working. The point is not to replace every Bullet-specific workflow; the point is to keep production context in the same workspace as the roast record.
- Use Rostoc when a Bullet roast should deduct from or reference green inventory.
- Use Rostoc when the roast should be tied to plans, batches, notes, and team records.
- Use Rostoc when future production needs a searchable history instead of isolated curve files.
- Keep native Bullet software available until Rostoc readings are validated on the exact machine.
When to stay with RoasTime or Artisan
Stay with RoasTime for native Bullet operation, machine-specific behavior, automation, and Roast.World ecosystem workflows. Stay with Artisan when the main need is highly configurable local logging and the operator is comfortable maintaining the technical setup.
Rostoc should not be positioned as the universal replacement for those tools. It is better described as the roastery record layer that can receive validated Bullet roast data.
Validation workflow before production use
A short validation roast is better than a long debugging session during production. Add the exact Bullet catalog entry, close other software that may own the USB device, record a short run, compare live values, and reopen the saved batch.
- Confirm the exact Bullet generation: R1, R1 IBTS, or R2.
- Use the Rostoc Aillio catalog entry instead of a generic serial device.
- Compare bean temperature and environment, drum, or IBTS readings with a trusted reference.
- Check that heater, fan, drum, and power-related streams appear as feedback rather than temperatures.
- Reopen the saved batch and confirm labels, values, and chart routing still make sense.

FAQ
What is the best Aillio Bullet software?
RoasTime is the native Bullet software, Artisan is a configurable logger, and Rostoc is useful when roast data should connect to green inventory, plans, batches, and production records.
Is Rostoc an alternative to RoasTime?
Rostoc can complement RoasTime for inventory-connected records, but it should not be treated as a replacement for native Bullet operation or control workflows.
Is Rostoc an alternative to Artisan for Aillio Bullet logging?
It depends on the job. Artisan is stronger for deep configurable logging. Rostoc is stronger when the roast record needs operational context and team production history.
Does Rostoc support Aillio Bullet R2?
Rostoc has experimental read-only USB logging support for the Aillio Bullet R2 catalog entry. Validate readings on the exact machine before production use.
