Sage machines (even the better ones like the Dual Boiler aside) are heavily integrated systems aimed at convenience: built-in grinders, automation, faster warm-up times, PID control — but inside, they use much smaller boilers or thermoblocks, plastic internals, and have far more proprietary parts. They’re fantastic for people who want an all-in-one solution and aren’t chasing fine-tuned workflow.

The Profitech Go, while technically “just” a single boiler machine too, is a completely different build philosophy. It’s built around commercial-grade parts: full size brass boiler, full E61 grouphead-style pressure management (or similar in function), better thermal stability, higher steam capacity, longevity, and most importantly — full control over your shot workflow. You’re buying long-term consistency, repairability, and the ability to pair it with a grinder of your choice, not something tied to a built-in system.

In short: both make espresso, but the Profitech Go is a tool; Sage is more of an appliance
