Coffee roasting software
Live software for the Croaster.
Bridge reads your Croaster over WiFi and streams every degree to your First Crack library at 1 Hz. Auto phase detection, event keyboard, cloud sync, community sharing.
Supported models
Croaster (WiFi)
TestedConnects over local WiFi. Live read of BT, ET, and computed RoR. Monitor-only (see below). Seeking our first real-hardware validator: request beta access and get priority review.
How it connects
WiFi (local network)
Bridge joins the Croaster on your local network and starts reading temperature data the moment it sees a signal. No USB cable required; no pairing flow.
- Croaster and your laptop on the same WiFi network
- macOS 26+ or Windows 10 build 19041+ / Windows 11
- No additional drivers required
Monitor-only today. Bridge reads the Croaster's temperature feed but does not drive heater, fan, or drum controls. You keep using the roaster's own panel for that. Live logging, phase detection, event keyboard, RoR, and cloud sync all work; the only thing missing is software-driven adjustment of the roaster itself. Recipes still run in guided mode, and the control strip records the moves you make by hand.
What you get
Recipes on a roaster we can't control
Bridge never pretends to command this rig, but your recipe still works: each step cues you at its trigger ("305°F: fan to 45%"), and one tap logs the move you made on the machine. The steppers in the control strip do the same for manual moves, marked Monitor · logs only. The result is something monitor rigs never get: a roast record with a full control history, not just a temperature curve.
Live BT + ET + RoR over WiFi
Bean and environment temps arrive from the Croaster over your local WiFi at 1 Hz, no cable in the loop. RoR is computed inline on a 30-second linear-regression window, the same math the rest of First Crack uses.
Automatic phase detection
Drying, Maillard, and development annotate themselves as bean temp crosses each boundary, turning the WiFi feed into a fully marked curve with nothing to tag by hand.
Event keyboard
Tap CHARGE, Turning Point, Dry End, First Crack, and Drop from the numpad while you work the Croaster's own panel. Bridge timestamps each one to the exact second.
Cloud sync from the first session
Each Croaster roast syncs to your account in real time over the same network it reads from. Open it on any device, with beans, cupping, and recipes together.
Community comparison
Publish your Croaster curves and see what other roasters pull from the same origins. Filter the community feed by origin, process, or roast level.
