For a prerecorded 24/7 YouTube channel, Castr is the clearer choice between these two. Its documentation explicitly describes continuous looping to YouTube, with infinite looping available on Premium and higher. StreamShark’s Live Scheduler supports scheduled VOD and indefinite loops, but its published guide limits access to subscriptions with a Dedicated Server and does not establish a direct YouTube handoff. Confirm that routing path with StreamShark before buying.
If you want a simpler cloud service focused on keeping an uploaded-video YouTube stream running, StreamNeo is the first alternative to consider: it loops from the cloud at any uploaded quality up to 4K 60fps for one flat price per slot, and the first day is free.
What each service can do for an always-on YouTube channel
Castr: documented continuous playout to YouTube
Castr’s prerecorded-live workflow plays uploaded video as a live broadcast. Its feature page names YouTube as a destination and describes continuous 24/7 looping. The page says infinite looping is available on Premium and higher; playlist size and maximum file duration also depend on plan. Check the current plan table for the limits that apply to your intended playlist. Castr pricing and plans.
For a more programmed channel rather than one repeating playlist, Castr also describes cloud playout that can schedule uploaded recordings and live streams into a continuous channel. It says the resulting broadcast can go to an embedded player, social destinations including YouTube, and custom RTMP/SRT destinations. Castr 24/7 cloud playout.

StreamShark: scheduler capability, but confirm the YouTube route
StreamShark’s Live Scheduler can schedule curated VOD at defined times or loop it indefinitely; the loop continues until manually stopped. Its support guide says the Scheduler is currently available to customers whose subscription has a Dedicated Server attached. The workflow selects an ingest and provides HLS and DASH feed URLs, but the reviewed documentation does not say whether the Scheduler sends directly to YouTube or requires an encoder, relay, or other feed configuration. StreamShark Live Scheduler guide.
StreamShark’s product page describes scheduled simulated-live playback of prerecorded content and support up to 4K. That description does not resolve the YouTube handoff question. StreamShark live streaming.

Which service fits which channel?
| Need | Better fit from published documentation | Why |
|---|---|---|
| A simple prerecorded playlist that loops to YouTube | Castr | Its prerecorded-live page explicitly names YouTube and continuous looping; infinite loop is listed for Premium and higher. |
| A programmed channel mixing scheduled recordings and live streams | Castr, based on documented destination path | Its cloud playout description covers both uploaded recordings and live streams, with YouTube among named destinations. |
| Scheduled or continuous VOD playout for an enterprise operation | StreamShark may fit, subject to confirmation | The Scheduler supports defined-time schedules and indefinite loops, but access is tied to a Dedicated Server subscription and direct YouTube delivery is not established in its guide. |
| Independent reliability winner | Not established | Both vendors make reliability-related claims, but there is no independent apples-to-apples uptime comparison for continuous YouTube channels. |
These are feature-documentation comparisons, not hands-on tests. A simulated-live loop plays prerecorded material as a live broadcast; it is not the same as producing a live camera feed.

A Castr help-center article dated December 1, 2022 says unlimited-duration streaming depends on an active subscription and sufficient bandwidth. Because the current plan page specifies bandwidth allowances, do not interpret that older wording as unlimited viewing at no extra cost. Castr help article on streaming duration.

Castr publishes a 99.9% uptime SLA and describes multi-CDN delivery. StreamShark describes multi-CDN delivery, dual DNS, primary and backup ingest with automatic failover, and real-time health monitoring. These are vendor descriptions or commitments; they do not establish which service delivers better real-world uptime for a continuously looping YouTube channel. Review the contract terms and ask each provider how failures in playout, ingest, or destination delivery are handled.

- What exact Enterprise plan and Dedicated Server configuration is required, and are there additional setup or usage charges?
- Which transfer, storage, active-stream and overage limits apply to the proposed configuration?
- How are primary/backup ingest and recovery handled for the exact Scheduler-to-YouTube route?
