Every multistream faces the same fork in the road: your single feed needs to be copied and sent to each platform, and that duplication either happens in the cloud or on your local machine. Both work. But they cost very different amounts and suit very different situations. Understanding the trade-off is the fastest way to stop overpaying for streaming.
How multistreaming actually uses bandwidth
Streaming to one platform at 6 Mbps uses 6 Mbps of upload. Streaming to four platforms means four copies — 24 Mbps — going out somewhere. The question is from where. With cloud multistreaming, you upload one copy to the provider and their servers send the four copies onward. With local multistreaming, your own PC sends all four copies directly, so you need roughly four times the upload bandwidth. That difference is the whole story.
Cloud multistreaming
With cloud multistreaming, you send a single stream to the provider's servers and they handle the fan-out to every destination. It's the convenient default, and for good reason.
The advantages: you only need enough upload for one stream, no matter how many platforms you target, so a modest connection can reach a dozen destinations. The stream keeps running on the provider's infrastructure even if your PC is busy or your local network hiccups, and you can start a 24/7 channel that runs when your computer is off entirely. Setup is usually the simplest, too.
The cost: that convenience is what you pay for monthly. Cloud providers carry the bandwidth and server load, and the subscription reflects it — the more destinations and the higher the quality, the more you tend to pay.
Best for: creators with limited upload bandwidth, anyone who wants always-on channels, streamers on laptops or the move, and people who value simplicity over squeezing out cost.
Local multistreaming
With local multistreaming, your own computer does the duplication and pushes each copy straight to the platforms. Nothing sits between you and the destinations.
The advantages: there's little or no per-month service cost, because you're using hardware and bandwidth you already pay for. You also keep full control of your setup and shave off a tiny bit of latency, since the stream isn't making an extra hop through a server.
The cost: you need the upload headroom to send every copy at once, which a lot of home connections can't sustain past two or three destinations at high quality. Your PC works harder, and if your power or internet drops, every destination drops with it — there's no server-side safety net.
Best for: streamers with strong, stable upload (fiber or business-grade), those targeting just a couple of platforms, and anyone determined to minimize recurring cost.
Cloud vs local: a quick comparison
- Upload needed: Cloud — one stream's worth. Local — one per destination.
- Monthly cost: Cloud — subscription. Local — little to none.
- Runs when PC is off: Cloud — yes. Local — no.
- Reliability safety net: Cloud — provider-side. Local — none.
- Best when: Cloud — limited bandwidth or need 24/7. Local — strong upload and cost-focused.
Why "either/or" is the wrong question
The most cost-effective setups often use both, depending on the stream. A creator might run their daily broadcasts locally to keep costs near zero, then flip to the cloud for a big event they want to reach ten platforms, or for an always-on channel that runs overnight. The trap is picking a tool that locks you into one mode — because your needs change stream to stream.
This is exactly the flexibility StreamTiler is built around. The same account can multistream from the cloud or from your own PC using an included Windows agent, and you can mix the two however you like — stream locally to save money when your connection allows, and switch to cloud when you need reach or 24/7 uptime. You're not paying for cloud bandwidth on the days you don't need it.
Here's what that looks like in practice. Say you stream to two platforms most weeknights on a solid fibre connection — run those locally and pay nothing extra for bandwidth. Then once a month you do a big event and want to hit six platforms at once, or you want a highlight reel looping to a channel overnight while you sleep. Flip those to the cloud. Over a month you've paid for cloud only on the days you actually needed it, instead of carrying a full cloud subscription for streams your own PC could have handled for free.
A worked example: what your upload can handle
Numbers make the trade-off concrete. Say you stream 1080p at 6 Mbps and want to reach four platforms:
- Local: 6 Mbps × 4 destinations = 24 Mbps of sustained upload, and you'd want maybe 30 Mbps to leave headroom so a busy moment doesn't drop frames. That rules out a lot of home plans, especially older cable connections with weak upload.
- Cloud: you upload one 6 Mbps feed — about 8 Mbps with headroom — and the provider sends the four copies. The same connection that struggled locally handles it comfortably, and it would handle ten destinations just as easily.
Run a speed test and look specifically at your upload figure, not download — they're often very different. Then multiply your bitrate by the number of destinations and compare. If the local number is anywhere near your real-world upload ceiling, the cloud is the safer choice.
Don't forget your hardware
Bandwidth isn't the only local cost. Every extra output your PC pushes is more work for its network stack, and if you're duplicating streams while also gaming and encoding on the same machine, you can hit CPU or GPU limits before you hit bandwidth limits. Hardware encoders (NVENC, AMD, QuickSync) help a lot here, but there's still a ceiling. Cloud multistreaming sidesteps this entirely — your PC only ever encodes and sends one stream, so its workload is identical whether you're live on one platform or a dozen. If your machine is already working hard during a stream, that alone can tip the decision toward the cloud.
How to decide for your setup
Start with two numbers. First, your reliable upload speed — run a test, then multiply your streaming bitrate by the number of platforms you want; if that exceeds what your connection can comfortably sustain, cloud is the safer route. Second, whether you need the stream to run when your computer is off — if yes, that's a cloud job by definition. If your upload is strong and you only stream while at your desk, local can save you real money. And if the answer is "it depends on the day," choose a tool that lets you do both.
The bottom line
Cloud multistreaming buys you convenience and low bandwidth requirements for a monthly fee; local multistreaming trades effort and bandwidth for near-zero recurring cost. Neither is universally better — the smart move is matching the mode to each stream, and ideally using a platform that lets you switch freely. StreamTiler does both from $3/mo, so you can start in the cloud and add local streaming whenever it saves you money.
