OUSAID keyboard software
sharkfin is a free, open-source replacement for the OUSAID app: remap keys, set the RGB, paint per-key colour and record macros on 13 OUSAID boards, 13 of which accept changes. Use it in a Chromium browser with nothing to install, or as an app on Windows, macOS and Linux. It runs entirely on your own machine, with no account.
Does sharkfin support my OUSAID board?
The table lists every OUSAID model sharkfin knows, 13 in all. Between them: knob, magnetic switches, 2.4 GHz, Bluetooth. If yours is missing, plug it in anyway: these boards report their own device id, and sharkfin identifies anything built on ROYUAN hardware from that reply, works out which command set it speaks, and asks before it writes.

"Writable" means sharkfin will change settings on it. Read-only boards are ones whose command set is not established yet; sharkfin identifies them and reads from them, but refuses to write, because the two protocol families in this hardware share opcodes that mean different things. "After a one-time check" means the picture exists but is confirmed against your own board first: two boards can share one picture and still disagree about which internal slot a key lives in, so sharkfin trusts the keyboard over its own files.
