What comes with it

Built to keep the stream up.

If one drops, the rest keep going

Each platform has its own connection: if one drops, only that one reconnects.

Safety nets

If OBS drops, BE RIGHT BACK goes on air without ending the stream. If your internet chokes, auto-bitrate eases the re-encoded destinations.

Platforms

The big four come ready.

And you can add any RTMP server.

  • Twitch
  • YouTube
  • Kick
  • Facebook
  • Custom RTMP
  • TikTokexperimental
  • Instagramexperimental
  • X (Twitter)experimental

TikTok, Instagram and X are experimental. Test each destination with your account and setup before an important stream: being in the app doesn't guarantee the platform will accept it.

Runs on your PC

No server in the middle. No monthly fee.

The stream goes from your computer straight to each platform, and your keys, settings and reports stay with you.

  • Free, no sign-up

The honest math

Every platform eats a chunk of your upload.

And re-encoding loads your GPU or CPU. Corneta measures your connection and shows, mode by mode, how much upload and PC the stream will take, before you go live.

Connecting your account is optional. With it, Corneta creates the YouTube broadcast, gets the key and brings in the chat; what it does with each permission is in the privacy policy.

Can I stream to Twitch and YouTube at the same time? Won't I get banned?

Each platform decides that, not Corneta, and the rules depend on your account type and any contract you signed. Corneta just sends your signal where you tell it to: before your first simulcast, check the terms of whoever you've signed with.

I use Streamlabs (or XSplit). Does it work?

It works. Corneta takes any program that streams over RTMP — just point it at the address the app shows you, same as you'd do with a platform. With OBS you get one extra shortcut: Corneta sets it up for you, and hits play when you press GO LIVE.

Does Corneta replace OBS?

No. You keep building scenes, camera and audio in the program you already use. Corneta picks up from there: it takes that signal, pushes it to the platforms, watches how each one is holding up, and keeps the stream's safety nets running.

I already use a multistream plugin in OBS. Why switch?

If all you want is to send the same video to more than one place, the plugin does the job. Corneta earns its place when the stream is more than that: it holds the stream up if OBS crashes (the plugin goes down with it, since it lives inside OBS), puts every platform's chat and alerts in one place and, at the end, builds a report for each one.

Is it really free? Will it turn into a subscription later?

It's free, with no sign-up and no trial. Everything that runs on your PC is open source and stays that way. If something paid ever shows up, it'll be an optional cloud service, and you'll know before.

Will it lag my game? Do I need a good graphics card?

Depends on the mode. Just copying the signal costs almost nothing. Re-encoding for each platform puts the work on the graphics card (recent NVIDIA, Intel or AMD) or, without one, on the processor, which hits harder. Corneta shows that load before you go live.

Am I going to need a lot of internet?

Each platform eats a slice of your upload. Before the stream, Corneta measures your connection, adds it all up and helps you pick a setup that fits with room to spare.

Does it work on macOS or Linux?

Today the download is Windows only. It's built so other systems can come later, but there's no date to announce. If you're on macOS or Linux, the answer is: not yet.

Go live everywhere.
