1. Multistreaming to Multiple Platforms
ストリームラボ: Multistream sends your live stream to YouTube, Twitch, and Facebook from one app. The free version handles the popular streaming platform list well. Setup uses automatic account linking, so newer users can broadcast in minutes.
カスター： Castr broadcasts to over 30 streaming platforms and custom RTMP sites at the same time. It pulls the stream key and url from each platform. This scale fits business audiences more than solo streaming.
2. Streaming Software and Encoder
ストリームラボ: Streamlabs Desktop is the encoder itself. You capture your screen, a capture card, or a camera inside the program. The Streamlabs OBS base gives full control over scenes without extra software.
カスター： Castr is not an encoder. You need encoder software like OBS to feed it a signal. You set Castr as a custom RTMP link, then it handles delivery and hosting from the cloud.
⚠️ 警告： Castr needs a stable connection and a separate encoder. Streamlabs bundles both, which is simpler for beginners.
3. Recording and Video Storage
ストリームラボ: Streamlabs records locally to your device in up to 4K quality. There is no cloud cap because files save to your own disk. This suits creators who edit footage after the stream.
カスター： Castr stores recordings in the cloud for up to 72 hours, with a 3-day storage window. It also hosts pre recorded videos and serves an HLS url for video on demand to OTT デバイス.
4. Stream Overlays and Customization
ストリームラボ: Streamlabs ships 250+ premade overlays and alert box themes. The easy customization options let you brand a stream fast. This is a top reason creators pick it over plain OBS, which ships none.
カスター： Castr focuses on delivery, not on-screen design. Overlays come from your encoder, not from Castr. It does add custom video galleries to showcase your brand or business.
5. Monetization and Paywall
ストリームラボ: Streamlabs collects tips through its built-in payment feature. It does not take a cut, so only standard processing fees apply. There is no paywall for gated video, though.

6. Cloud Delivery and Akamai CDN
ストリームラボ: Streamlabs sends your feed straight to each platform from your PC. Stream quality depends on your own internet speeds and hardware. There is no extra delivery layer in between.
カスター： Castr is built on top of Akamai CDN. It uses adaptive bitrate and a failover ingest to keep streams stable. Using multiple sources at once can lower latency and reduce buffering.
7. Video Editing Tools and Repurposing
ストリームラボ: The ultra subscription bundles a video editor, Cross Clip Pro, and auto subtitles. Cross Clip Pro editor turns a long live stream into short clips. ポッドキャスト repurposing helps you post across other services.
カスター： Castr has no built-in video editor. Its transcoder and cloud playout handle delivery, not editing. You would edit elsewhere, then host the finished video on Castr.
8. Ease of Use and Interface
ストリームラボ: Streamlabs has a user friendly dashboard that newer users grasp fast. Account linking and premade themes mean you can create a stream in one sitting. It is widely seen as beginner friendly.
カスター： Castr has a clean dashboard, but the encoder step adds a learning curve. Once set up, users report it works without glitches during live events. Reviews call the service reliable with minimal ダウンタイム.
9. Analytics and Viewer Engagement
ストリームラボ: Streamlabs adds chat integration and alerts that boost viewer engagement. Its analytics track viewers and tips in the same console. This keeps a creator’s community in one window.
カスター： Castr gives video analytics with a 30-day retention window for real-time データ. You can schedule a livestream and embed the player on your own website. The focus is broadcast metrics, not chat.

🏆 WINNER: STREAMLABS
Streamlabs wins 4 out of 6 categories.
最適な用途: Gamers, solo content creators, and newer users who want one free app.
Streamlabs and Castr solve two different problems. Streamlabs is an all-in-one app for content creation, overlays, and tips. Castr is a cloud platform for business broadcast and gated, paid video.
