Companion 4.2.5 from Bitfocus transforms consumer-grade keypads such as the Elgato Stream Deck into fully fledged broadcast-style control surfaces, giving operators one-touch command over an ever-growing ecosystem of more than 350 hardware devices and software services. Released as the ninth major iteration since the project began, the open-source application maps buttons to functions inside video switchers, routing matrices, audio consoles, lighting desks, character generators, PTZ cameras, media servers, presentation tools, streaming encoders, and even generic TCP/UDP or OSC endpoints. Typical installations range from solo content creators who need fast scene changes in OBS to multi-camera studios that demand synchronized tally, router salvos, and projector shutter control, and from corporate AV teams automating Microsoft PowerPoint and Zoom hand-offs to houses of worship that trigger lyrics, lighting presets, and streaming destinations from a single keypad page. Users build these workflows through a browser-based configuration interface where each button can be assigned multiple timed or conditional actions, custom iconography, variable feedback, and color states that update in real time to reflect device health or on-air status. Companion’s active community continually expands the module library, ensuring support for new protocols and firmware revisions, while the software itself is distributed at no cost and is available for free on wget.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
