Pick the Keychron K5 if a number pad, dedicated multimedia keys, and a full-size layout matter more than firmware options. Choose the Lofree Flow 2 if compact dimensions, VIA or QMK support, and its gasket-and-foam construction better match your desk and customization plans. Both are low-profile hot-swappable keyboards, so standard MX keycaps are not compatible with either.

What will you mostly use it for?
The K5 fits buyers who want a full-size keyboard, multimedia keys, or a broader set of switch styles. The Flow 2 has the stronger feature case for programming and customization because it combines VIA and QMK support with hot-swap sockets. Its compact layout also favors buyers wanting fewer keys, though the K5's listed weight is lower. For gaming, the K5 has more switch-type variety, while both list 1000 Hz polling; neither has a clear stated polling-rate edge.
Pick the Keychron K5
- The K5 offers linear, tactile, and clicky switch options, while the Flow 2 listing describes three Lofree x Kailh Cloud options including silent linear and tactile types.
- The K5 vendor lists 1000 Hz wired polling, while the Flow 2 metadata also lists 1000 Hz polling, so neither has an evidenced polling-rate advantage.
