What is Onyx - Screen Recorder?

Onyx is a free screen recording tool that captures video in up to 4K resolution. It operates on a local-first principle, meaning recordings are processed and saved on your device rather than uploaded to external servers. This approach prioritises privacy and gives you direct control over your files. The tool is straightforward to use; you start recording, capture your screen activity, and save the output locally. It's suitable for anyone who needs to record tutorials, demonstrations, meetings, or gameplay without paying for a subscription or worrying about cloud storage.
