Let's be straight: Artisan is excellent, free, and open source. If your whole workflow is live curve control, keep it. RoastSource is for everything Artisan doesn't do — and it will read your .alog files, with import coming soon.

.alog and CSV roastsRoast with Artisan driving the probe, as always. Then RoastSource holds everything around it: which green you used and how much is left, how the cup scored, what blend it went into, and what to change next batch. When import arrives, you can bring your .alog files in. And if you’d rather log temps in one place, Home reads a USB (Mastech) or WiFi (BounceBuster) probe live, with real-time Rate of Rise.
Nothing to install, nothing to configure, nothing to cancel.
