Logitech has released a Developer Edition of its MX Master 4 mouse, originally launched in September 2025, as a tribute to "developers who are shaping the digital world". The hardware remains identical to the standard model, featuring the same 8,000 DPI sensor, MagSpeed scroll wheel capable of 1,000 lines per second, built-in haptic feedback, and the Action Ring button for shortcuts. It also retains the 650 mAh battery with up to 70 days of use, USB-C quick charging, and multi-device pairing. Basically, nothing has changed under the hood or in terms of functionality.
The differences are purely visual. The new edition uses a two-tone dark and light gray scheme with bright green accents. There are laser-etched syntax annotations including // and </> markup tags, circuit traces, and a {Hello, World} execution prompt. Logitech has also added a few Easter eggs: 0xFF + 1 referencing World Programmers' Day, 09.17 for the Linux Kernel release date, and !04.01 for World Backup Day.
The good news is that the MX Master 4 Developer Edition costs the same as the standard model. The mouse is currently listed on the Logitech website for $120 / €130, together with the two-year warranty.
