Video goes up to 4K if your webcam or camera supports it.
Over 100,000 podcasters and creators use the platform worldwide.

🏆 Winner: Zencastr
Record studio quality tracks without asking a guest to install software. The free plan is enough to publish your first few podcasts.
Zencastrの価格
Here is what a Zencastr account costs in 2026.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | $0 | Testing a first show with a guest |
| 育つ | 月額24ドル | Weekly podcast interviews and hosting |
| 規模 | 月額40ドル | Teams that need more seats and storage |
Pricing verified August 2026.

無料トライアル: 14 days on paid plans, with no credit card required at signup.
返金保証: No published refund window. The free plan is the safer way to test first.
📌 注記: Hosting is included in the price. Bought separately, podcast hosting usually runs $12 to $15 per month, so paid plans absorb a cost you would pay elsewhere.
⚠️ Pricing conflict: Some sources list a Professional plan at $18/month ($216/year) and a Growth plan at $45/month ($540/year), plus two free tiers. Our CSV records Free, Grow at $24/month and Scale at $40/month. We use the CSV figures throughout. Check the pricing page for the current lineup and any coupon code before you subscribe.
Zencastrの主な利点
Zencastrが注目に値する理由は以下のとおりです。
- Local capture: Each mic is recorded on that person’s computer. A weak internet connection no longer ruins the take.
- Separate tracks: Every participant gets an isolated audio track. You can cut one voice without touching the others.
- Real-time cloud upload: Files upload while you record, which gives you redundant backups if a computer crashes mid session.
- 自動ポストプロダクション: Zencastr levels audio, removes background noise and normalizes volume after you stop.
- テキストベースの編集: AIツール let you edit the recording by editing its transcript, including filler words.
- Virtual green room: Guests test mic and camera before the recording session starts.
- Publishing built in: Hosting and distribution reach Spotify, Apple Podcasts and YouTube from one dashboard.

Castrとは何ですか?
Castr is a live streaming platform for broadcast media and media production teams.
It takes one signal from your encoder and sends it to many places at once.
You connect ストリーミングソフトウェア such as OBS through the Castr dashboard.
From there Castr streams to over 30 supported sites, including Facebook pages and YouTube.
Delivery runs on the Akamai CDN, which keeps buffering and latency low for viewers.
It also pulls RTSP supported IP cameras straight into the platform.

This video shows the dashboard and the setup flow in practice.

Runner Up: Castr
Push one live stream to Facebook, YouTube and Twitch together. Add a paywall or advertising when you want to charge your audience.
Castrの価格
Castr sells five tiers. You can upgrade or downgrade at any time with no contract.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| スターター | 月額12.5ドル | A first livestream on a small budget |

| プロ | 月額62.5ドル | Paywall standard use and heavier bandwidth |
| プレミアム | 月額104.5ドル | Multiple concurrent streams for a 仕事 |

機能比較
These two products barely overlap. The table below shows where each one actually competes.
| 特徴 | ゼンカスター | カストル |
|---|---|---|
| 開始価格 | 月額24ドル | 月額12.5ドル |
| 無料プラン | ✅ | ❌ |
| ローカル録音 | ✅ | ❌ |
| マルチストリーミング | ❌ | ✅ |
| Separate Guest Tracks | ✅ | ❌ |
| Transcription and Text Editing | ✅ | ❌ |
| Paywall / Ads | Ad marketplace | Paywall and ads |
| Encoder Required | ❌ | ✅ (OBS or similar) |
| 最適な用途 | ポッドキャスト録音 | ライブビデオストリーミング |
1. Recording vs Broadcasting
ゼンカスター: Nothing goes out live. Each person’s mic is captured on their own machine, then uploaded. That design is why the platform can record high quality audio even when someone’s connection wobbles mid call.
カスター: Everything goes out live. You point an encoder at Castr, and Castr fans that signal out to your chosen platforms. There is no local capture, so your upload speed sets the ceiling.
⚠️ 警告: If you want both a live audience and a clean archive, you need two tools. Neither one covers the other’s job.
2. Audio and Video Quality
ゼンカスター: Every guest gets a 16-bit 48k WAV file, the standard for studio quality work. Video reaches 4K with the right camera. Because it saves your voice locally, crystal clear audio does not depend on internet speeds.
カスター: Quality is whatever your encoder sends. The transcoder then builds adaptive bitrate renditions so viewers on slow connections still watch without buffering.

3. Editing and Post-Production
ゼンカスター: AI tools generate a transcript, then you delete text to delete audio. Filler words come out in a click. Automatic post-production levels tracks and strips background noise, and live editing lets you trim during the recording process.

カスター: No editor at all. Whatever you broadcast is what people see, so any polish has to happen in OBS before the signal leaves your computer.
4. Clips, Repurposing and Scheduling
ゼンカスター: AI clipping pulls short vertical cuts out of a full video for social. It is the fastest route from a long episode to something you can post the same day.

カスター: Cloud TV Playout runs a scheduled channel from files you already made. Scheduling a playlist to go live at a set hour is something Zencastr simply cannot do.
5. ホスティングと配信
ゼンカスター: Hosting sits inside the same account, and distribution reaches Spotify, Apple Podcasts and YouTube. You do not pay a separate host, which is a real saving for a new podcast host.

カスター: Video hosting covers on demand files as well as live streams. Storage limits climb with each tier, and the top plan is where large bandwidth allocations kick in.

6. Monetization
ゼンカスター: An ad marketplace matches your show with advertisers. You do not chase sponsors yourself, but you also do not set the rate.

カスター: You charge viewers directly through a paywall, or run in-stream advertising. For paid workshops and ticketed entertainment events, that control matters more than a marketplace.
7. Devices and Inputs
ゼンカスター: An iOS app records on iPhone and iPad at the same local multi-track quality. Mobile デバイス are treated as real recording sources, not a fallback.

カスター: Inputs lean hardware. An RTSP camera can feed the platform directly, which suits a venue, a church or a fixed camera position more than a mobile setup.

8. Player and Embedding
ゼンカスター: An embeddable player drops an episode onto your website. Zencastr streams finished episodes through that player, so listeners never leave your page.

カスター: The white label OTT layer goes further. You can build branded video galleries and ship an HLS URL to Roku or Apple TV, with your own elements on the player.

9. Automation Under the Hood
ゼンカスター: Transcription runs automatically after you stop, and unlimited transcriptions come with the paid tiers. Those transcripts feed the editor, the clips and your show notes.

カスター: The cloud transcoding server handles the heavy processing so your machine does not. Failover ingest reduces the risk of a dead broadcast if the primary feed drops.

10. 価格設定とコスト
Side by side, the plans are hard to compare directly because you are buying different things.
| ティア | ゼンカスター | カストル |
|---|---|---|
| 無料 | 無料:0ドル | ❌(7日間無料トライアルのみ) |
| 入場料支払い済み | Grow:月額24ドル | Starter: $12.5/month |
| 中 | 料金:月額40ドル | Standard: $33.5/month |
| Upper mid | ❌ | Professional: $62.5/month |
| 高い | ❌ | Premium: $104.5/month |
| トップ | ❌ | Ultra: $250/month |
ゼンカスター: Two paid tiers, and the cheaper one already includes hosting. The free plan covers two guests for 8 hours a month, which is enough to publish real episodes before you spend anything.
カスター: Starter undercuts Grow by about half, but the ladder climbs fast. Pro plan users pay $62.5/month, and the jump to Ultra is where a 仕事 with heavy bandwidth ends up.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |

| Remote interviews for a podcast | ゼンカスター | Local tracks per guest |
| One broadcast on multiple platforms | カストル | 一度に30以上の目的地へ |
| To spend nothing this month | ゼンカスター | Free plan, no card needed |
| To charge viewers for access | カストル | 組み込みの有料購読システム |
| Editing without an audio degree | ゼンカスター | Edit the text, not the waveform |
| IP camera or venue streaming | カストル | Direct RTSP ingest |
💰 あなたの予算
Castr’s entry price is lower, but there is no free tier to fall back on. If you just started podcasting, Zencastr lets you publish for $0 first.
🔌 あなたの技術スタック
Castr assumes you already run an encoder and can manage stream keys. Zencastr assumes nothing beyond a browser and a decent mic.
🎙️ Your Format
A weekly two-person conversation belongs in Zencastr. A monthly event you want people to watch live belongs in Castr.
🎓 あなたの経験レベル
Beginners get further with Zencastr because the setup is one link and a green room check. Castr rewards people who already understand bitrate and latency.
🆓 無料トライアルとデモ
Zencastr gives 14 days on paid plans with no credit card required. Castr gives 7 days on Starter, so explore it during a week you actually have an event.
🛟 サポートオプション
G2 reviews single out Castr’s live chat as responsive and continuously available. Zencastr support is slower to reach but the product needs less hand-holding.

私たちのレビューで取り上げられなかったこと
We focused on solo creators and small teams. We did not test enterprise contracts, custom plans, or peer to peer failover across multiple internet sources. Long-run reliability over months of weekly shows is outside what we can claim here. Reports of audio quality issues and dropouts come from user reviews, not from a controlled test on our side.

🏆 優勝:ZENCASTR
Zencastr wins 4 of 7 categories.
最適な用途: Remote podcast interviews, multi-guest shows, creators who want recording and hosting in one bill
Zencastr wins here because most people typing this comparison want a podcast, and it does that job with fewer moving parts. Zencastr makes a good recording almost automatic.
Castr is not the weaker product. It is a different one, built for livestreaming to an audience in real time.
If you run ticketed events, church services or gaming livestreams, Castr is the correct pick and the rating gap is irrelevant.
For everyone else recording conversations, Zencastr is the safer place to start.

ゼンカスター対 リバーサイド
Zencastrが勝利した点: lower entry price for hosting plus recording, a usable free tier, and a simpler dashboard for a first-time podcast host
リバーサイドが勝利した理由: higher ceiling on video work, stronger clip tooling for short form, and a wider set of export options for 編集者

And here is where Castr sits among other streaming services:
キャストル対 再ストリーム
Castrが勝利した点: Akamai-backed delivery, IP camera and MPEG-TS ingest, and OTT output for Roku and Apple TV
Restreamが勝利した点: a browser studio that needs no encoder, unified chat across destinations, and a free tier for testing
キャストル対 ストリームラボ
Castrが勝利した点: multistream capacity at higher tiers, paywall monetization, and video hosting for on demand libraries

💡 プロのヒント: Whichever service you pick, book a quiet recording room and test your gear first. Recording over Skype or Zoom compresses your sound, which is the single biggest shortcut people regret in the podcast production process.
