Multi-device keyboard remap studio

A cross-platform web remapper for niche keyboards like NIZ, with all-layer visual comparison

Problem

A user built an open-source web remapper for the NIZ ATOM66 because the official config tool is Windows-only, forcing Mac users to spin up a VM just to tweak a few keys; and when editing multiple layers there is no way to see them side by side, so users toggle back and forth from memory.

Solution

A browser-based remapping workbench for multiple niche keyboards: connect via WebHID or a local bridge, read and write mappings live; show normal layer, left Fn, right Fn side by side with cross-layer copy; export configs as JSON for backup and sync across machines.

Users

Programmers using NIZ, Keychron, Anne Pro, or other keyboards lacking a good Mac config tool, especially those syncing layouts across multiple computers.

MVP

Support 1-2 popular niche keyboards; read and write key mappings; show all layers side by side with cross-layer copy; local save and JSON import/export; no account, fully static deploy.

Revenue

Free with paid cloud sync for multiple keyboard profiles and team-shared layouts; or a one-time purchase desktop bridge.

Why now

WebHID is now stable in mainstream browsers, and the niche keyboard community is active but long underserved on Mac, so an indie tool can win through open-source reputation.
