ZSA makes two of the most popular premium split keyboards on the market: the ErgoDox EZ and the Moonlander. Both offer radically different typing experiences than standard staggered keyboards, utilizing columnar layouts, total split designs, and highly customizable firmware via Oryx. However, choosing between the older, bulkier ErgoDox EZ and the sleeker, highly portable Moonlander Mark I comes down to more than just aesthetics. We tested both to compare their thumb clusters, tenting capabilities, portability, and overall ergonomics to see which ortholinear board truly justifies its premium price tag.
The ErgoDox EZ is designed for users with larger hands who want maximum key availability. Its classic 76-key layout includes a massive thumb cluster that, while powerful, requires significant stretching. Conversely, the ZSA Moonlander targets a broader audience with a modernized, floating-key design, integrated wrist rests, and an adjustable thumb module. At $365 for the Moonlander and around $354 for a fully equipped ErgoDox EZ, the investment is nearly identical. Your decision will hinge entirely on your hand size, travel needs, and preference for thumb cluster ergonomics.
The ZSA Moonlander is the clear winner for most users due to its adjustable thumb cluster, integrated wrist rests, and superior portability. However, the ErgoDox EZ remains the better choice for users with very large hands or those who explicitly need 76 keys for complex macro setups.

Thumb Cluster Ergonomics and Reach
The thumb cluster is the most significant differentiator here. The ErgoDox EZ features a flat, six-key thumb block on each half. Unless you have exceptionally large hands, reaching the outer thumb keys requires awkward wrist movement, largely defeating the ergonomic purpose. The Moonlander solves this with a 4-key hinged thumb module that tilts upward. This brings the keys closer to your natural resting thumb position, dramatically reducing fatigue. For the vast majority of hand sizes, the Moonlander’s adjustable cluster provides a vastly superior, strain-free typing experience.
Tenting and Tilt Capabilities
Tenting allows you to elevate the center of the keyboard to reduce forearm pronation. The ErgoDox EZ uses a robust six-leg system that offers limitless, incredibly stable tenting and tilting angles. The Moonlander relies on a built-in leg and the folding thumb cluster to create its tenting base. While the Moonlander is easier to set up initially, using the thumb cluster as a tenting leg forces it to point downward, which ruins thumb ergonomics. For aggressive, customized tenting angles without compromise, the ErgoDox EZ easily wins.
Portability and Desk Footprint
The ErgoDox EZ features thick plastic bezels, a chunky profile, and detached silicone wrist rests. It claims a massive footprint on your desk and requires a dedicated, bulky carrying case to move safely. ZSA engineered the Moonlander specifically for mobility. It features a modern floating-key design, minimal bezels, and wing-like wrist rests that fold perfectly flat against the bottom of the board. The Moonlander easily slips into a laptop bag without adding bulk. If you commute to a hybrid office, the Moonlander is undeniably the better choice.
Layout and Keycap Customization
Both keyboards run on QMK firmware, customized via ZSA’s intuitive Oryx web configurator. The software experience is identically flawless. However, the ErgoDox EZ offers 76 keys versus the Moonlander’s 72. Furthermore, the EZ uses standard 1u, 1.5u, and 2u keycaps, making it incredibly easy to find custom aftermarket keycap sets. The Moonlander uses proprietary piano-style and triangular keys on its thumb cluster, effectively locking you into ZSA’s default thumb keycaps. If visual customization and keycap swapping are your top priorities, the ErgoDox EZ takes the lead.
Build Quality and Aesthetics
The hardware differences between the two are visually stark. The ErgoDox EZ looks like a piece of retro industrial equipment. It is incredibly durable, but the thick, injection-molded plastic feels slightly dated for a $350 device. The Moonlander feels like a premium, modern piece of tech. It utilizes a slimmer profile, a sleek matte finish, and floating keys that allow the per-key RGB lighting to spill out beautifully across your desk. The Moonlander easily justifies its premium price tag through superior modern design and materials.

Our Verdict
Buy the ZSA Moonlander for a modern, travel-friendly design with superior thumb ergonomics suited for most hand sizes. Choose the ErgoDox EZ only if you have large hands, demand extreme tenting angles, or want completely unrestricted aftermarket keycap compatibility.
