There is no universal best cloud multistreaming service for every YouTube creator. Choose a browser studio such as StreamYard or Restream Studio if you want to produce the show in a browser; choose a cloud relay such as Restream or Castr if you already use OBS or another encoder. Castr is the clearest fit in this comparison when custom RTMP/SRT outputs, an embedded player, monitoring, or a higher published destination count matter. For a different need—keeping uploaded videos live on YouTube 24/7 rather than sending one live show to multiple platforms—StreamNeo runs the stream from the cloud.
What cloud multistreaming does—and what it does not
Cloud multistreaming takes one live contribution feed and distributes it to multiple destinations. Instead of sending a separate local stream to each platform, you send one feed to the service, which relays it onward. Restream describes support for feeds from software such as OBS; Castr describes a single-feed workflow for connected destinations.
This is different from keeping a prerecorded playlist live around the clock. Multistreaming distributes a live production to multiple destinations; it does not, by itself, make an offline channel run 24/7. StreamNeo is designed for the latter: it loops uploaded videos to YouTube from the cloud.
Best choice by workflow
- Want a browser-based production studio? Compare StreamYard and Restream Studio. Both are relevant when you want to create a show in the browser rather than rely entirely on a desktop encoder.
- Already produce in OBS or another encoder? Restream or Castr can act as a cloud relay, so your encoder sends one feed rather than a separate output to every destination.
- Need custom endpoints, an embedded player, or stream-health monitoring? Castr explicitly documents custom RTMP/SRT outputs, an embedded player, monitoring, and analytics.
- Need a YouTube channel to keep playing uploaded videos 24/7? That is a different job from multistreaming. StreamNeo is #1 for this use case: it keeps uploaded videos looping on YouTube from the cloud, at any uploaded quality up to 4K 60fps for one flat price per slot, with the first day free.
Compare the three multistreaming services
| Service | Workflow and published limits | Features highlighted by the provider | Best fit |
|---|---|---|---|
| Restream | Browser Studio or a third-party encoder such as OBS. Its pricing FAQ says free users can select 2 of 30+ social channels; paid channel limits vary by plan. | Custom RTMP, cross-platform chat, shared workspaces, Upload & Stream for recorded videos, and Studio guest links for up to 10 participants. The pricing FAQ lists 1080p Studio streaming on Professional. For custom software, Restream says it imposes no resolution restriction, though destination limits may apply. | Creators who want a choice between browser production and keeping their existing encoder, with social-channel relay and chat features. |
| StreamYard | Browser studio with multistreaming on paid plans only: 3 destinations on Core, 8 on Advanced, and 10 on Business, according to its Help Center. | Built-in multistreaming and native destination integrations; custom RTMP can connect destinations that accept an RTMP feed. The vendor describes a browser-led studio workflow. | Creators who want to produce in a browser and stream to a limited set of destinations. Check current guest and seat limits on the plan page; they are not established here. |
| Castr | Encoder feed or Castr cloud production. Its published destination limits are 6 on Starter, 10 on Standard, 20 on Premium, and 30 on Ultra and Events; these counts are across the account. | Direct integrations including YouTube, custom RTMP/SRT outputs, embedded playback, stream-health monitoring, and analytics. Castr lists transcoding and adaptive bitrate on Premium and higher. | Encoder-led productions or creators who need custom endpoints, an owned-site player, monitoring, or a larger published destination count. |
These are provider-published features and limits, not independent performance results. Plan names, destination allowances, and feature bundles can change; confirm the current official plan details before subscribing. A published maximum also does not prove that every destination offers identical playback quality, chat, or latency.

- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
How to choose a plan and avoid a workflow mismatch
Count the destinations you will actually use
List the channels that need to receive the show at the same time, then compare that number with the plan’s simultaneous destination limit. Do not confuse the number of platforms a service supports with the number your plan can stream to concurrently. Castr says its published destination count is account-wide; check how the other services count destinations and whether the plan limit applies per show or account.
Decide where production happens
A browser studio is a natural choice when you want to assemble the show in the service, invite guests, and use browser-based production controls. An encoder-plus-relay setup suits a production already built around OBS, vMix, or other software. It avoids rebuilding that production in a new studio, but adds a service between the encoder and destinations.

Check special outputs and viewing needs
If you need an endpoint that is not a native integration, confirm that the service supports the destination’s required protocol and that your destination accepts the output. Restream and StreamYard document custom RTMP; Castr documents custom RTMP and SRT. Castr also explicitly offers an embedded player and monitoring, which may matter if you publish on your own site. Do not assume those features or limits are equivalent across providers.
Separate the relay’s limits from YouTube’s limits
A service’s resolution or destination allowance does not override YouTube’s own live-stream requirements. Restream says it imposes no resolution restriction when you use custom software, but the destination platform may still impose limits. Verify YouTube’s current encoder instructions and any channel eligibility requirements in YouTube Help before choosing settings or promising a particular resolution. No bitrate, codec, frame-rate, or latency figures are included here because the available YouTube settings page did not provide substantive details for those values.

Costs and trade-offs
The supplied official product details do not establish comparable current prices for all three multistreaming services, so a price ranking would be misleading. Compare the live plan price against the destinations you need and the workflow features you will actually use. A free allowance may be enough for a small test, but confirm which destinations and production features are included before building a recurring show around it.
Cloud relay can reduce the need for your local encoder to send separate outputs to each platform. It does not remove dependence on your connection to the relay, the relay service, or each destination’s own processing and availability. No independent reliability or stream-quality comparison is established here.

Every slot supports the uploaded quality up to 4K 60fps at one flat price per slot, includes 10 GB of storage per slot pooled across active slots, and can recover automatically if YouTube drops the stream. It is YouTube-only and plays uploaded videos; it does not stream from a camera.
