A CasparCG alternative for live stream graphics
CasparCG is the open-source graphics and playout server developed at SVT, the Swedish public broadcaster, and it has been on air in real television for well over a decade. It is genuinely excellent. It is also a server, not a product — and that is why people search for an alternative.
What CasparCG does well
CasparCG plays video, audio and HTML templates out of a rundown, with frame accuracy, over SDI through a Decklink card or over NDI. It handles key and fill, multiple channels and layers, and it is controlled by AMCP commands over TCP from whatever client you like.
For a station that needs a real playout server and has an engineer who knows it, there is no reason to look elsewhere. It is free, it is proven, and it does not go away when a vendor loses interest.
Where small teams get stuck
- There is no operator interface in the box. The server is the product; the panel your operator uses is something you or a third party builds.
- Templates are a project. HTML templates are powerful, but somebody has to write them, wire up the update calls and test the in/out animations.
- The video path assumes broadcast. Getting the output into OBS usually means a Decklink card, NDI, or a screen-capture workaround.
- Nothing knows about your show. Match clocks, squads, score logic and rundowns are all things you supply — the server plays whatever it is told.
None of these are faults. They are the consequences of being a server rather than an application. But a two-person stream measuring setup time in evenings feels every one of them.
What the lighter alternative looks like
LowerThird Software attacks the same problem from the application end. The templates already exist as complete design families, the control panel is the product rather than an exercise for the reader, and the output is a transparent HTML5 page that OBS takes as a browser source with no capture card involved.
You give up what a playout server is for: frame-accurate SDI playout, key and fill on a hardware keyer, multi-channel rundowns, deep AMCP automation. You gain being on air the same evening you install it.
Which one fits you
- Choose CasparCG if you need SDI key/fill, frame-accurate playout, multiple channels, or you already have a developer building your control surface.
- Choose a browser-source CG if your video path is OBS, vMix or Streamlabs, you want lower thirds and score bugs tonight, and you would rather adjust a colour than compile a client.
- They coexist happily. Both end up as a layer in the same encoder, so nothing stops you running CasparCG for playout and a light CG for straps.
Same idea, finished Templates, panel and transparent output in one install. Ask for an early-access build.
