Stream everywhere. Own everything.
Your stream, your machine, your software. A dedicated encoder per destination pushes each platform its best — no cloud relay, no monthly bill.
- 01Self-hosted by design.
The encode happens on your machine. Your stream goes straight from you to the destinations — never through a cloud we run.
- 02An encoder per destination.
A dedicated encoder for every platform you target. Push 1440p60 to YouTube and 1080p60 to Twitch at the same time — never bottlenecked by the lowest-quality channel.
- 03One license. Yours forever.
A one-time purchase. No subscriptions, no usage tiers, no platform fees stacked on top. Updates included for a year; the version you bought keeps working.
Destinations
Built for every platform worth being on.
A dedicated encoder per platform, each tuned to the quality it accepts. Anything else that speaks RTMP, SRT, or WHIP works too, including your own server.

Independence
Yours end to end. Locked to no one.
No cloud on the hot path, no plugin wired into your studio, no platform you’re stuck with. Polycast takes your feed and answers only to you.
No cloud in the middle
The encode happens on your machine and goes straight to each destination. Your stream never passes through infrastructure we run, because there isn’t any on the path.
Not a plugin, not tied to OBS
Point OBS, vMix, or any RTMP/SRT/WHIP source at it. It’s a standalone app, not a plugin bolted into your scene software — so it can’t destabilize the tool you produce in, and you’re never locked to one.
Runs where you want it
On the machine you stream from today, or a separate box that does the heavy encoding while you send it one feed from a laptop. A headless self-hosted build is on the roadmap.
Comparison
Why creators are leaving the cloud.
Hosted multistream services are convenient — and convenient never gets cheap. Polycast trades the rental model for ownership.
Platforms
Self-hosted, three ways.
Native desktop apps for macOS and Windows, plus a self-hosted Docker image on the roadmap. All three run the same orchestrator, so your setup moves with you.
macOS
The media engine in your Mac encodes every destination in hardware — the CPU stays free for the show.
Coming soon
Windows
Runs on the machine you already stream from — every destination encoded locally, never the cloud.
Coming soon
Docker
No desktop in the loop. Run the broadcast server headless on a VPS or home box — always on.

Frequently asked
Questions, answered.
How is this different from Restream or StreamYard?
Those run in the cloud: you upload one feed, they re-encode it and relay the same quality to every platform, and you pay every month. Polycast runs on your own machine with a dedicated encoder per destination — push 1440p60 to YouTube and 1080p60 to Twitch at the same time, straight from you to each platform. One-time license, no cloud in the middle.
Is this an OBS plugin?
No — Polycast is its own application. You point OBS at it (or any source that speaks RTMP, SRT, or WHIP) and it handles the per-destination encoding and fan-out. Because it isn’t a plugin running inside your scene software, it can’t destabilize the tool you produce in.
Do I need OBS?
No. OBS is one option, not a requirement. Anything that can send an RTMP, SRT, or WHIP stream works — vMix, a hardware encoder, a camera that outputs RTMP, or your own script.
Can I run it on a server or VPS?
That’s on the roadmap. Today it runs on the machine you stream from; a headless self-hosted build is planned, so you’ll be able to send one feed from a laptop and let a bigger box do the encoding and fan-out.
Do I need a powerful computer?
The encoding runs in hardware — the media engine in your Mac, or the GPU in your PC — so it stays off the CPU. A current Apple Silicon Mac or a Windows machine with a recent GPU handles several destinations comfortably. More destinations and higher resolutions just want a bit more encoder headroom.
What about bandwidth?
Each destination gets its own stream straight from your machine, so your upload carries all of them at once — roughly the combined bitrate of every destination. Make sure your upstream covers the total. Cloud services hide this by uploading once and fanning out on their servers; the tradeoff is they cap your quality and bill monthly.
How does pricing work?
One-time purchase, not a subscription. No per-destination fees, no usage tiers — the version you buy keeps working, and updates are included for the first year. Pricing lands at launch; join the waitlist to hear first.
