Keyboard Studio

Keyboard Studio lets you test web keyboard configurators without plugging in every keyboard. It adds virtual WebHID devices from a local JSON catalog to supported configurator sites and to sites you add yourself. The extension is a tool for developers and testers of configurator software. It ships without a device database: you import your own JSON catalog from the extension popup, and it stays in your Chrome profile. Features: - Import a catalog by drag and drop or file picker; group models by brand and product line. - Connect one model, the models shown by a filter, or every checked model with one click. Unchecked models turn grey and move to the end of the list; named checkbox sets let you switch between selections. - Device manager with virtual and physical devices side by side: pause, disconnect, match a physical keyboard to its virtual model, choose which source the site receives. - Device emulation: settings written by the configurator (keymap, Fn layer, lighting, macros, game mode, triggers) are read back, with four profiles and factory reset. - Failure testing: reply latency, timeouts, dropped or corrupt replies, send errors, disconnect after N commands, firmware version, battery level, charging and bootloader mode. - HID log of virtual and physical device traffic with decoded commands, filters and JSON export. - Custom models without editing the catalog file, and custom configurator sites (Chrome asks for access to each site you add). - Chrome's standard WebHID chooser stays available for real devices. - Interface in English and Russian. Privacy: no device database, passwords or API keys are bundled. The catalog, settings and logs stay on your computer; the extension sends nothing to a server, has no analytics and loads no remote code.
