Streamloop vs Castr

Updated October 16, 2026

Focused prerecorded cloud playout compared with a broader multistreaming, hosting, production, and OTT platform.

Primary job

Streamloop logoStreamloop
Continuous cloud playout of prerecorded video or audio, with up to 5 destinations per stream.
Castr logoCastr
Broad live-video infrastructure spanning multistreaming, hosting, monetization, cloud production, APIs, OTT, and prerecorded playout.

Category overlap

Streamloop logoStreamloop
Directly serves unattended prerecorded playlist streaming.
Castr logoCastr
They overlap in Pre-Recorded Live and TV Playout; most of Castr's platform does other jobs.

Indefinite prerecorded looping

Streamloop logoStreamloop
Yes. A published playlist can run indefinitely while credits remain available.
Castr logoCastr
Yes in Pre-Recorded Live on Premium and above. TV Playout looping is unavailable below Premium and is capped at 15 days on Premium or 30 days on Ultra and Events.

One-to-many multistreaming

Streamloop logoStreamloop
Yes, up to 5 destinations per stream; each one after the first adds $6 per 30 days at 1080p while live.
Castr logoCastr
Yes. One ingest can be relayed to 6, 10, 20, or 30 account-wide destinations, depending on plan.

Destination setup

Streamloop logoStreamloop
Managed YouTube through Google authorization, or a manual YouTube stream key; custom destinations use an RTMP URL and key.
Castr logoCastr
Native social-platform integrations plus custom RTMP or SRT destinations. Direct and custom endpoints both count toward the account-wide destination allowance.

Browser production

Streamloop logoStreamloop
No browser studio, webcam or guests. Live Scenes, Streamloop's mode for live inputs, has a scene editor and takes OBS, vMix or IP camera feeds.
Castr logoCastr
Cloud Production provides browser switching, flows, overlays, media sources, and transitions. Output goes up to 1080p60, configured by the Castr team during access setup, and contributors connect as streams, not through a guest room.

Hosted video and OTT

Streamloop logoStreamloop
Not a video-hosting or OTT platform.
Castr logoCastr
Player, analytics, recording, paywall, and hosting features span the plans. Events adds a branded web app, CMS, SVOD, and TVOD; native TV and mobile apps are separately scoped.

Cloud prerecorded quality

Streamloop logoStreamloop
Up to 4K60; HDR to YouTube only.
Castr logoCastr
TV Playout is 720p30 through Premium and can reach 1080p60 on Ultra or Events. Castr does not list 4K for its prerecorded modes.

Playlist limits

Streamloop logoStreamloop
Up to 1,000 items per playlist.
Castr logoCastr
Pre-Recorded Live allows 2 to 15 files per stream by plan; TV Playout allows 5 to 50 files.

Storage model

Streamloop logoStreamloop
Uploads are free. The first 30 GiB of large-playlist storage is free, then $0.35 per GiB-month while live.
Castr logoCastr
Hosted-video storage and dedicated prerecorded-video allocations are separate, plan-capped allowances.

Pricing model

Streamloop logoStreamloop
Billed by the minute while live, from prepaid credit or an optional monthly plan, plus a one-time encoding charge for files that need it.
Castr logoCastr
Fixed monthly or annual subscriptions with plan gates and account-wide allowances.

Comparable always-on price

Streamloop logoStreamloop
About $10 per 30 days at 1080p and 30 fps, plus a small one-time charge for files that need encoding.
Castr logoCastr
Infinite Pre-Recorded Live looping starts on Premium at $199.99 monthly or $1,999.99 annually.
Real cost

What a 24/7 stream actually costs, by quality

Streamloop bills by the minute. Pick a resolution and frame rate, and pay only while you are live. Optional monthly credit plans are also available. Below is the cost of a stream running nonstop for a full 30 days.

Metered by the minute, so a week of streaming costs about a quarter of these figures, and a day about a thirtieth. Files that need encoding add a one-time ~$0.005 per minute of encode time; files that are ready to stream skip it. Uploads and idle loops are free, and so is the first 30 GiB of large-playlist storage.

A 1080p stream running 24/7 on Streamloop is about $10/month, and you only pay while it is live. For comparison, Castr lists: Core plans from $19.99/month; infinite looping from $199.99/month.

Which should you pick?

When each tool is the right call

There is no objective winner, only which tool fits your actual job.

Pick Streamloop if… logo

Pick Streamloop if…

Pick Streamloop when the real job is an affordable, unattended prerecorded playlist rather than a complete video platform.

  • You need continuous prerecorded video or audio playout to a managed YouTube channel or compatible RTMP destinations, up to 5 per stream.
  • You would rather pay by the minute than a high fixed plan, for one always-on channel or for streams that run only some of the time.
  • You want playback in order, shuffled without repeats, or in a custom order described in plain words, with playlist edits that start at the next clip.
  • You want free uploads, imports from Google Drive or a link, separate audio playlists, or control through an API or MCP.

Streaming is billed by the minute, only while live: one 24/7 stream at 1080p is about $10 per 30 days. Start with a $1 trial week, which becomes a monthly plan unless you cancel, or top up and pay as you go.

Start the $1 trial
Pick Castr if… logo

Pick Castr if…

Pick Castr when prerecorded playout is one part of a professional distribution, hosting, monetization, production, or OTT stack.

  • One contribution feed must reach several destinations without creating a separate playout job for each endpoint.
  • You need hosted VOD, an embeddable player, viewer analytics, paywalls, advertising, or OTT workflows.
  • Operators need cloud switching, recording, stream-health monitoring, SRT or WHIP ingest, or pull-link support.
  • Castr's plan limits and the price of Premium or higher are fine for everything else you get.
  • Your linear channel needs scheduled breaks, EPG data, or other Castr livestreams as playout sources.

Castr plans start at $19.99 a month, but nonstop looping of prerecorded video starts on Premium at $199.99 a month.

FAQ

Streamloop vs Castr: FAQ

The questions people actually ask before picking one

Is Castr a direct Streamloop alternative?

Partly. Castr's Pre-Recorded Live and TV Playout do the same job as Streamloop. Its multistreaming, video hosting, monetization, cloud production and OTT tools go further, and Streamloop does not try to replace them.

Which is better for multistreaming to several platforms?

Castr is the better choice when one live feed must reach many destinations. Streamloop sends a stream to up to 5 destinations, and each one after the first adds $6 per 30 days at 1080p while live.

Can Castr Starter loop prerecorded content forever?

No. Starter and Standard can stream prerecorded video, but endless looping starts on Premium. TV Playout loop mode also starts on Premium, and a loop runs for up to 15 days on Premium or 30 days on Ultra and Events before you need to set a new end date.

Which is less expensive for one continuous prerecorded channel?

Streamloop is cheaper for one nonstop channel. A 1080p stream at 30 fps running nonstop is about $10 per 30 days, plus a small one-time encoding charge for files that need it. Castr's endless looping starts on Premium at $199.99 a month, but that plan includes a much broader platform.

Does Streamloop replace Castr video hosting or OTT features?

No. Choose Castr when hosted playback, VOD libraries, monetization, audience analytics, cloud production, or OTT operations are central requirements. Choose Streamloop when those features would be overhead and the primary need is unattended prerecorded playlist playout.
