The bottom line
Castr can replace several video tools, but check tier caps and commissions before committing.
Castr bundles streaming delivery, recording, hosting, playout, monetization and OTT. The pricing page lists Starter at $19.99 monthly or $16.67 per month with annual billing paid upfront; Starter includes two concurrent streams monthly, six destinations, 200 GB monthly bandwidth and 100 GB storage. A seven-day trial is listed, with no free plan.
The catch is that some of the strongest capabilities sit higher up: failover ingest is listed on Ultra, while the branded web app and SVOD/TVOD are on Events. Events lists a 5% OTT commission, and the pricing details list a 9% paywall commission on all plans. One Reddit thread suggests RTMP direct to YouTube may be simpler for a basic setup; commenters also describe extra network requirements for SRT. That is useful context, not broad evidence of customer satisfaction.

01What Castr actually does
Castr combines live video delivery, recording, hosting, 24/7 playout, monetization, and white-label OTT in one platform. The pitch is to replace a stack of separate video services, not just relay a feed to social channels. It works with RTMP or SRT encoders and says its multi-CDN setup uses Akamai, Fastly, and CloudFront, with a 99.9% uptime SLA. Castr also lists automatic backup-ingest failover, which switches to a standby encoder feed if the primary drops.
For a simpler workflow, it can send one broadcast to multiple destinations, including custom RTMP and SRT endpoints. For a fuller video business, it offers always-on channels built from live and recorded content, advertising, subscriptions, pay-per-view, audience insights, and branded OTT options. The pricing page lists a seven-day free trial and annual prices starting at $16.67 per month, billed upfront yearly; monthly billing starts at $19.99.
02Where Castr is strong
Castr’s appeal is consolidation: delivery, multistreaming, recording, hosting, and monetization sit under one service. That can mean fewer vendors to coordinate, though the plan caps matter. Its stated feature set includes multi-CDN routing, automatic backup-ingest failover, and 24/7 playout with ad insertion. Castr also supports RTMP and SRT destinations, so a broadcaster can send one feed to multiple platforms rather than manage each output separately.
The pricing page lists these annual-billing tiers:
- Starter: $16.67/month, billed annually ($19.99 month to month), with 6 destinations, 200 GB monthly bandwidth, and 100 GB storage.
- Standard: $41.67/month, billed annually ($49.99 month to month), with 10 destinations, 500 GB monthly bandwidth, 200 GB storage, and SRT/RTMP pull links plus in-stream advertising.
- Premium: $166.67/month, billed annually ($199.99 month to month), with 20 destinations, 3 TB monthly bandwidth, 2 TB storage, API access, and three team members.
Castr also lists branded web apps and SVOD/TVOD on Events, with 30+ payment gateways. That is a broader package than a basic multistreaming tool, provided you need the OTT features.
03Where it falls short
The headline starting price leaves out the limits that can force an upgrade. Starter and Standard both allow two concurrent streams on monthly billing, or three on annual billing; their destination caps are six and 10. Premium raises those to five concurrent streams monthly (10 annually) and 20 destinations. Ultra lists 10 concurrent streams monthly (15 annually), 30 destinations, and 5 TB monthly bandwidth. Events costs $624.99 per month with annual billing or $749.99 month to month, and lists 15 concurrent streams, 30 destinations, and 10 TB monthly bandwidth.
Failover ingest is listed with Ultra, not as a Starter or Standard inclusion. The pricing page also lists a 9% paywall commission on all plans and a 5% OTT commission on Events, so monetization revenue is not commission-free. Native mobile and TV apps are separately scoped for Events, while sub-second streaming is an add-on on Premium, Ultra, and Events. Those extras make the entry price a poor guide to the cost of a broadcast-grade or branded OTT setup.
SRT can add network setup work. In one Reddit thread, streamers describe port, firewall, and static-IP requirements for some SRT setups; RTMP may be simpler when sending directly to a platform.
04Castr pricing: what you'll actually pay
Castr has no free plan; the pricing page lists a 7-day free trial. Starter costs $19.99 month to month or $16.67 per month with annual billing, paid upfront. That buys 2 concurrent streams on monthly billing (3 on annual), 6 destinations, 200 GB monthly bandwidth (2.4 TB upfront annually) and 100 GB storage. Standard is $49.99 monthly or $41.67 annually, with 10 destinations and 500 GB monthly bandwidth. Premium jumps to $199.99 monthly or $166.67 annually; it adds 20 destinations, 3 TB monthly bandwidth, API access and 3 team members. Ultra costs $349.99 monthly or $291.67 annually, with 30 destinations and failover ingest. Events is $749.99 monthly or $624.99 annually, with 15 concurrent streams, 30 destinations and branded OTT tools. Annual pricing works out to roughly two months free, but requires upfront payment. Watch commissions: Castr lists a 9% paywall commission on all plans and a 5% OTT commission on Events. DRM is an add-on; sub-second streaming is available on Premium, Ultra and Events. Native apps are separately scoped for Events.
05Switching to (or from) Castr
Castr says it works with RTMP and SRT encoders, so teams using those formats may be able to keep their existing encoder while changing delivery and hosting. Before switching, inventory your destinations, concurrent-stream needs, bandwidth, storage and any failover requirements: those caps vary by plan, and failover ingest is listed on Ultra, not Starter. For OTT, confirm how your branded web app, payment setup and any separately scoped native apps fit your requirements before moving paid content. Castr’s published materials do not publish migration steps, data-export options or a process for moving recordings and audience data out. Treat portability as an open question and get the answer in writing before you commit. The published published material includes no Reddit posts about why customers leave Castr, so we can’t substantiate a Reddit-based churn pattern. The clearest documented switching risks are plan limits, the 9% paywall commission on all plans and, for Events OTT, an additional 5% commission.
From the threadsWhat users say
The Castr-related Reddit material is a narrow technical discussion, not a broad set of customer reviews. Commenters describe SRT as potentially more resilient on variable networks but more involved to configure; one says a paid Castr subscription can handle RTMP via SRT, while another asks why not send RTMP directly to YouTube.
RTMP basically just uses the internet and gets to its end destination whenver and however it needs to get there
SRT can be more resilient and handle more variable networks than RTMP. But it’s not magic, it won’t make a bad connection suddenly good
SRT basically requires a handshake between devices, which means the two devices need to talk back and forth, thru your firewall, which is why ports need to be opened
However, yes, if you wanted to pay for a subscription to Castr to send RTMP via SRT it will work
Questions people ask
What is Castr streaming?
Castr is a live video platform for delivery, hosting, recording, 24/7 playout, monetization and white-label OTT. It supports RTMP and SRT encoders, and its multistreaming sends one live feed to 30+ platforms, including custom RTMP and SRT destinations. Pricing starts at $19.99 per month when billed monthly, according to the published pricing details.
Is Castr a legitimate streaming service?
The published product information describes Castr as a live streaming platform and lists plans, features and a 7-day free trial. That supports describing it as a marketed service, but it does not independently verify the company, customer support, billing practices or service performance. We would check current terms and cancellation details before paying.
Is Castr reliable?
Castr says its multi-CDN delivery uses Akamai, Fastly and CloudFront, and the service lists a 99.9% uptime SLA. Backup ingest failover is listed for Ultra. Those are provider claims, not independent performance results. Reddit commenters say SRT can handle variable networks better than RTMP, but warn that it cannot fix a poor connection.
Is Castr safe to use?
The published information does not publish security certifications, encryption details or account-protection features, so we can’t verify Castr’s security from these sources. One Reddit discussion notes that SRT setups may require an open port and public IP, which has network and firewall implications; that is a protocol setup concern, not evidence of a Castr security problem.
Can Castr take SRT and send to YouTube over RTMP?
Castr’s product information says it works with SRT or RTMP encoders and can multistream to 30+ platforms, including custom RTMP destinations. In one Reddit discussion, a commenter says a paid Castr subscription can send RTMP via SRT. The sources do not spell out the exact configuration or confirm which plan supports that workflow, so check with Castr before subscribing.
