ArcLight vs OBS Studio: a Mac alternative for presenters
ArcLight is a Mac app that turns slides into live video, and a deck-first alternative to OBS Studio for people who present. OBS Studio is free, open-source broadcast software for Windows, macOS and Linux that streams directly over RTMP and grows with plugins. ArcLight is for Mac users who present, teach or host a show and would rather build it like a presentation: every scene is a slide, every slide has a transition such as Magic Move, and a presenter view and teleprompter are built in. ArcLight costs $49.99 a year after a 30-day trial. OBS is free.

The difference is the model
OBS Studio is a broadcast engine. You build scenes from sources, add filters, and arrange docks around a mixing-console interface. It streams to every major platform, has a built-in virtual camera, Studio Mode and an Apply LUT filter, and a large plugin ecosystem fills the gaps.
ArcLight starts from the deck. The navigator on the left is your run of show, the canvas holds live cameras, screens, app windows, images, video and titles, and the inspector sets a transition for each slide. Press Play and step through with the arrow keys, a clicker or a Stream Deck. The program goes to the ArcLight Camera virtual camera, a .mov recording, or a second display.
Choose OBS if
you need Windows or Linux, rely on plugins or remote guests through a browser source, or the price has to be zero. It's the more capable broadcast engine.
Choose ArcLight if
you'd rather build a show like a deck, with slides, per-slide transitions and builds, and want a presenter view and teleprompter built in. It suits you best when you go live through Zoom, Teams, Meet or a recording.
Coming from OBS
- Scene becomes a slide. Its order in the navigator is the order of the show.
- Source becomes a layer: camera, display, window, image, video, text or shape. Each camera or screen runs one shared capture no matter how many slides show it.
- Studio Mode becomes studio-mode preview and Take.
- Scene transition becomes a per-slide transition: Magic Move, Dissolve, Push, Wipe, stinger clips and more.
- Audio Mixer becomes the Audio panel in the toolbar: microphones, other apps' audio and video clips, each with gain, mute and a meter. Recordings and streams are kept in lip sync, and Sync Cameras lines each camera up with a clap.
- Browser source becomes a web graphic: HTML, CSS and JavaScript built into the show, rather than a live web page.
- Virtual camera becomes ArcLight Camera, which shows your real camera whenever you aren't playing (a “starting soon” card if no camera works).

For presenting, teaching and hosting shows, yes. ArcLight covers the core of OBS (cameras, screens, scenes, transitions, recording and a virtual camera) arranged like a slide deck, with Magic Move, a presenter view and a teleprompter built in.

Yes. Go Live streams the program over RTMP to YouTube, Twitch, LinkedIn or any custom RTMP server. It also goes live through any app that accepts a camera, such as Zoom, Teams, Meet or Webex.

Yes. In studio mode you select the next slide as a preview while the current one stays on air, then Take it live with its transition.
