Overview¶

Cropster is a cloud-based coffee roasting software platform used by commercial and specialty roasters worldwide to log, analyse, and replicate roast profiles. Founded in Austria in 2008, Cropster integrates with thermocouples and data loggers connected to drum and fluid-bed roasters to provide real-time curve visualisation — displaying bean temperature, environmental temperature, and Rate of Rise — alongside post-roast analysis tools, inventory management, production scheduling, and quality control workflows. It is the most widely adopted professional roast logging platform in the specialty coffee industry and has become a de facto data standard for roast profile exchange and reproducibility.

Core Functions¶

Cropster's primary value is real-time roast monitoring and post-roast analysis:

Real-time roast logging: - Displays bean temperature and drum/environmental temperature curves during roasting - Calculates and displays Rate of Rise (RoR) in real time - Shows elapsed time, current temperature, and phase markers (charge, turning point, first crack, drop) - Allows roasters to overlay a reference profile (guide curve) from a previous roast so the current roast can track against it

Post-roast analysis: - Records and stores every roast log with searchable metadata (green coffee lot, batch size, operator, roast target) - Calculates Development Time Ratio, total roast time, turning point temperature and time, charge temperature, drop temperature - Enables comparison between batches on the same green coffee to diagnose consistency variation - Generates production reports and batch quality summaries

Inventory and production: - Tracks green coffee inventory with lot-level traceability - Links roast logs to specific green coffee lots for full batch traceability - Production scheduling tools for multi-roaster commercial environments

Quality control integration: - Cupping score records can be linked to roast profiles - Colour measurement integration (Agtron, ColorTrack) for roast colour tracking

Connectivity¶

Cropster connects to roasters through USB or Ethernet-connected data loggers or through direct manufacturer integrations with roasters that have digital communication protocols. Compatible roasters include Probat, Loring, Giesen, Diedrich, Mill City, and many others. Thermocouples are typically K-type and positioned in the bean mass (for bean probe temperature) and drum environment (for environmental temperature). The software runs on desktop (Windows/macOS) with cloud sync to the Cropster Roasting Intelligence platform.

Artisan Comparison¶

Cropster's principal competitor as a roast logging platform is Artisan Software — an open-source, free-to-use alternative with comparable real-time logging and profile overlay features. Artisan is widely used by small-batch and home roasters and by professionals who prefer local data control. Cropster offers cloud-based multi-user access, inventory management, and production scheduling that extend beyond what Artisan provides, making it better suited to commercial-scale operations. The choice between platforms typically reflects scale: Artisan for single-roaster specialty operations; Cropster for multi-roaster commercial or production environments.
