OBS Studio (also known as Open Broadcaster Software, or OBS) is a screen-casting and live-streaming software available across multiple platforms including macOS, Windows and Linux. Boasting features typically only found in commercial screen recording apps, OBS also provides one of the simplest workflows with an intuitive and easy-to-learn interface that makes recording and streaming a breeze. It's also totally free and open-source.
- Great software if you're looking for an alternative to Captura that also works on macOS and Linux. The main difference is that you can also stream videos with OBS while Captura can only record your screen.
