Best Castr Alternative
Quick answer: TPStreams is the best Castr alternative for businesses that sell access to video. Widevine and FairPlay DRM, domain restriction, token-based playback and REST API access are included on every TPStreams plan from $150/month. On Castr, by its own documentation, DRM is an add-on, domain and geographic controls start on Premium, and API access starts on Premium.
Castr is strong at multistreaming, playout and paywall monetisation — things TPStreams does not offer at all. If those are why you’re paying, stay where you are.
What Is Castr?
Castr is a live streaming and video platform built around multistreaming, hosting, playout and monetisation. From its own pages:
- Multistreaming, with 6 to 30 destinations account-wide depending on plan
- RTMP and SRT ingest, cloud production, live transcoding, live-to-VOD and 24/7 playout
- Multi-CDN delivery across Akamai, Fastly and CloudFront edges, with adaptive playback
- Paywall, pay-per-view and subscription monetisation, plus pre-roll ads from your own VAST tag — at a 9% commission on paywall sales, on every plan
Castr’s PlayReady support is broader than TPStreams’, which covers Widevine and FairPlay. For a broadcaster pushing one feed out to many destinations and selling tickets through a paywall, Castr does things TPStreams does not attempt.
Why Look for a Castr Alternative?
Three capabilities that a protected-content business needs are gated or sold separately on Castr. All three come from Castr’s own documentation.
DRM is an add-on on every plan
Castr’s feature list describes DRM as “Available as an add-on on every plan,” and its platform page repeats that DRM is an add-on regardless of tier. Castr does not publish a price for the add-on, so the cost of protecting your content cannot be determined from the pricing page.
TPStreams includes Widevine and FairPlay on every plan from $150/month, with published licence volumes — 55,000 at Start rising to 1,000,000 at Scale.
Domain and geographic controls start on Premium
Castr’s video hosting page states: password protection on every plan, domain allowlisting and geographic controls on Premium and higher.
For a course business, domain locking is usually the first control you want — it stops your embed being lifted onto another site. On Castr that requires reaching the Premium tier. On TPStreams, domain restriction is included from the entry plan alongside token-based playback and role-based access control.
API access starts on Premium
Castr’s platform page states that transcoding and API access start on Premium, and that sub-second latency is an add-on on Premium and higher.
If you are integrating video into an LMS or your own application, API access is not optional. TPStreams includes REST APIs and webhooks on every plan, plus SDKs for JavaScript, Android, iOS, React and Flutter.
Add the three together and the entry-level comparison changes shape: Castr’s headline price is far lower, but DRM, domain control and API access — the three things a paid course library actually runs on — are either an unpriced add-on or a Premium-tier feature.
Castr vs TPStreams
| Castr | TPStreams | |
| Published entry price | $19.99/month, or $16.67 billed annually | $150/month |
| DRM | Multi-DRM (Widevine, FairPlay, PlayReady) — add-on on every plan, price not published | Widevine + FairPlay included on every plan; published licence volumes 55,000 → 1,000,000 |
| Domain & geo controls | Premium and higher | Included on every plan |
| API access | Starts on Premium | Included on every plan, with webhooks and five SDKs |
| Password protection | Every plan | Token-based playback from your own backend |
| Watermarking | Viewer watermarking | Per-session forensic watermarking – user ID, email, and IP burned into playback |
| Live ingest | RTMP and SRT | RTMP from OBS, vMix, Wirecast, hardware; DVR; auto-recording |
| Storage | 100 GB to 3 TB | 150 GB to several Peta Bytes |
| Analytics | Playback analytics, 30-day retention | Engagement analytics on all plans: watch time, completion, drop-off, device, geo |
Where Castr is genuinely better: multistreaming, playout, OTT apps, built-in paywall and advertising, SRT ingest, PlayReady coverage, and a much lower entry price. None of those are things TPStreams competes on.
Why TPStreams Is the Better Castr Alternative for Paid Content
Everything a protected library needs, in the plan
| Plan | Price/mo | DRM licences | Delivery | Storage | Live hrs |
| Start | $150 | 55,000 | 750 GB | 150 GB | 24 |
| Pro | $450 | 110,000 | 6 TB | 700 GB | 130 |
| Growth | $1,350 | 300,000 | 26 TB | 2 TB | 430 |
| Scale | $4,050 | 1,000,000 | 90 TB | 10 TB | 2,000 |
DRM, domain restriction, token playback, API access, webhooks, engagement analytics and AI subtitles are included at every tier. Growth and Scale add a named customer success architect and a contractual SLA.
Protection depth from the entry plan
- Widevine and FairPlay on every plan, as a direct Google Widevine partner
- Per-session forensic watermarking — user ID, email and IP burned into playback, so a leaked recording identifies its source
- Token-based playback using short-lived tokens issued from your own backend
- Domain restriction and role-based access control
- ISO 27001 and SOC 2 Type II, with AES-256 encryption at rest and in transit
Live class to protected library, same plan
TPStreams ingests RTMP from OBS, vMix, Wirecast or hardware encoders, delivers adaptive HLS over a global CDN, and includes DVR inside the live session so a late-joining student can pause and rewind. Auto-recording puts the finished class into the library already transcoded, DRM-protected and generating analytics.
Proven in regulated training
NISM — the securities-market certification body mandated by SEBI — runs mandated certification training on TPStreams. A joint venture of AAI and DGCA delivers regulated aviation training on it. Art of Living has streamed live to audiences across 180 countries. TPStreams reports 50,000 concurrent viewers on a single stream, 4 PB delivered monthly and 99.999% uptime over the last twelve months.
- What is the best Castr alternative?
TPStreams is the best Castr alternative for businesses that sell access to video. Widevine and FairPlay DRM, domain restriction, token-based playback, REST API access and engagement analytics are included on every TPStreams plan from $150/month, with published DRM licence volumes from 55,000 to 1,000,000.
- Does TPStreams include API access on every plan?
Yes. REST APIs with JSON responses and webhooks are included on every TPStreams plan, along with SDKs for JavaScript, Android, iOS, React and Flutter. Castr’s platform page states that transcoding and API access start on its Premium tier.
- How does TPStreams protect against leaks?
Beyond Widevine and FairPlay encryption, TPStreams applies per-session forensic watermarking that burns the viewer’s user ID, email address and IP into playback, so a redistributed recording identifies the account it came from. Domain restriction, token-based playback and role-based access control are included on every plan.
- Does TPStreams handle live streaming?
Yes. TPStreams ingests RTMP from OBS, vMix, Wirecast or hardware encoders, delivers adaptive HLS over a global CDN, and includes DVR inside the live session. Live hours are bundled into every plan — 24 on Start up to 2,000 on Scale — and auto-recording puts the finished stream into your library already transcoded and DRM-protected.
