Castr is a broad broadcasting and video-hosting platform that combines multistreaming, VOD hosting and 24/7 pre-recorded channels across 30-plus destinations. If all you want is to loop a single pre-recorded video 24/7 without a computer on, [StreamZop](/signup) is a focused, lower-cost alternative built only for that job. Both can keep pre-recorded video live around the clock from the cloud, so the difference is how much platform sits behind it. Castr is closer to a full broadcaster, with hosting, a CDN, embeddable players, multistreaming and analytics, which is powerful if you run video as a business. StreamZop strips that back to one thing: you upload a video, paste a stream key, and it loops as a pre-recorded live stream with automatic restarts if the connection drops. Because a simple loop does not need video hosting or CDN delivery, you are not paying for infrastructure you will not use. For a hosting and multistreaming stack, Castr fits; for one always-on loop, a looper does.
What Castr is good at
Castr is strong as an all-in-one broadcaster. It hosts video, delivers it through a CDN, gives you embeddable players, multistreams live to 30-plus platforms at once, and runs scheduled pre-recorded channels with analytics on top. If you need to host your library, embed players on your own site, and broadcast widely from one dashboard, that combined stack is its core strength and it covers a lot of ground for teams that treat video as core infrastructure.
Where StreamZop fits instead
StreamZop does one thing: it loops an uploaded video as a 24/7 live stream, from the cloud, with automatic restarts if the connection drops. There is no video library to manage, no CDN to configure and no player to embed. You upload a video, paste a stream key, set it to repeat, and it stays live around the clock. For a channel that only needs to keep one feed running on YouTube, that focus means less to learn and a lower bill, because you are not carrying hosting and delivery features a single loop never touches.
How to decide between them
Ask whether you need a video platform or just an always-on loop. If you want to host video, embed players, gather analytics and multistream, Castr gives you that whole stack. If you only need one recorded video repeating on one channel around the clock, a looper is the better fit. It is the same trade-off in the guide to the best 24/7 streaming software: pay for a broadcasting platform when you use it, and pay for a looper when the job is simply keeping a video live.
What people loop instead of hosting video
Most people reaching for a Castr alternative are not building a video platform. They want one always-on channel, a music station, an ambience scene, a gameplay loop or podcast reruns, that stays live without a PC. For that, hosting, CDN and embeddable players are overhead that a single loop does not use, while the parts that matter are simplicity and a reliable restart. If you later need multistreaming or hosting, the OneStream Live alternative and Restream alternative comparisons cover the broader tools.

Frequently asked questions
How much does Castr cost?+
Castr uses tiered plans that scale with features like multistreaming, hosting and destinations, and its pricing changes over time, so check castr.io for current rates. For one always-on loop, a focused looper like StreamZop is usually cheaper because you are not paying for hosting and delivery.
What is Castr used for?+
Castr is used for multistreaming live video to many platforms, hosting and delivering video through a CDN, embedding players on your own site, and running scheduled 24/7 pre-recorded channels. It is a broad video platform rather than a single-purpose looper.
Is there a free alternative to Castr or Restream?+
Both Castr and Restream have offered limited free tiers, though terms change, so check their sites for current pricing. StreamZop starts with a 7-day free trial so you can test a full 24/7 loop before paying, without setting up hosting or multistreaming.
What is the best free live streaming?+
For live capture, OBS Studio is free and open source but needs your PC left on. For an always-on 24/7 loop, StreamZop offers a 7-day free trial so you can run a real looped stream from the cloud before committing, which OBS cannot do on its own.
Why choose StreamZop over Castr?+
Choose StreamZop when the job is simply keeping one recorded video live 24/7 from the cloud, cheaply and with automatic restarts, and you do not need hosting, a CDN or embeddable players. Choose Castr when you want a full broadcasting and video-hosting stack.
Which is cheaper for a single 24/7 channel?+
For the single job of keeping one recorded video live around the clock, a focused looper is usually cheaper because you skip video hosting, CDN and multistreaming features. Compare current pricing on each site, since plans change over time.
