Castream

Castream is a multistreaming service for sending mobile or desktop broadcasts to several destinations at once. It best suits creators and organizations that want distribution, chat, and recordings in one workflow. Its breadth is useful, but the free plan’s five-minute sessions make it a poor fit for ongoing broadcasts.

Overview

Castream routes a single stream to YouTube, Twitch, Facebook, Facebook Pages, TikTok, Instagram, LinkedIn, or custom RTMP destinations. YouTube, Twitch, and Facebook support OAuth connections; TikTok, Instagram, X, LinkedIn, and custom destinations use an RTMP URL and stream key. The range is broad, though RTMP setup asks for more configuration than signing in.

Mobile users can capture their screens on iOS and Android; Android also supports a live camera overlay over a shared screen. Desktop broadcasters can send output from OBS Studio or other RTMP-compatible software to Castream for redistribution. Automatic recordings can be reviewed, downloaded, shared, or replayed from the dashboard, which gives streamers a useful follow-up to live distribution.

Key features

Chat, presentation, and AI tools

A unified inbox lets streamers view and respond to chat from connected platforms. Live chat overlays, lower thirds, live badges, and custom text help keep audience interaction and on-screen presentation in the same workflow. AI tools generate titles and descriptions, analyze audience sentiment, and suggest content. These extras make Castream more than a destination relay, although creators who only need redistribution may not need the added layer.

Mobile and desktop streaming

Screen capture on both mobile platforms gives phone-based creators a way to share app activity, while Android’s camera overlay adds a face-to-face element. Desktop users can keep their existing OBS or RTMP-compatible setup and use Castream to send it onward. The plan limits on destinations and video quality still matter: the service is better suited to creators comfortable with its stated 720p Creator tier or 1080p Pro tier than those seeking higher resolutions.

Pricing

Castream has a free plan, a 3-day trial, and paid plans starting at $9.99 a month. The Free plan costs nothing and allows two simultaneous destinations, 720p at 1.2 Mbps on mobile or 720p at 2 Mbps on desktop, sessions up to five minutes, and a Castream watermark. That is enough for brief tests, not regular services or creator broadcasts.

Creator costs $9.99 a month, billed $9.99 / month or $99.99 / year. It raises the limit to three simultaneous destinations, offers 720p at 2.5 Mbps on mobile or 720p at 4 Mbps on desktop, and removes the session-time limit with priority ingestion. It is the sensible step up for a solo creator who streams regularly to a small set of services and can work within 720p.

Pro costs $16.99 a month, billed $16.99 / month or $169.99 / year. It supports five simultaneous destinations at 1080p and 6 Mbps, with priority support. Choose it when five outlets, higher resolution, or priority help justify the added monthly cost; those who need only three destinations and 720p can stay on Creator.

Platforms

Castream is available on Android, iOS, and the web. Mobile screen capture works on both mobile platforms, while the camera overlay over shared screen is an Android feature. Desktop streaming is supported through OBS Studio or other RTMP-compatible software.

Who it's for

Castream identifies churches, gamers, musicians, fitness coaches, and solo creators as users. It is a strong fit when one broadcast needs to reach several platforms and the operator also wants unified chat and recordings. Churches can consider it for multistreaming and sermon archiving; creators who need longer sessions must move beyond Free. For a one-destination workflow, its multistreaming allowance may be more than necessary.

Pros and cons

• Broad destination support: YouTube, Twitch, Facebook, TikTok, Instagram, LinkedIn, and custom RTMP options cover varied audiences in one workflow.
• Useful interaction tools: Unified chat, overlays, and recordings keep audience response and post-stream access alongside distribution.
• Free plan is sharply limited: Five-minute sessions and a watermark make it a trial option rather than a practical regular-streaming tier.
• Creator remains 720p: The cheaper paid plan removes time limits but not the resolution ceiling; 1080p requires Pro.
• Some destinations need manual connection details: RTMP URL and stream key setup is less direct than OAuth sign-in.

Alternatives

Restream is worth considering for a broader platform footprint, including Linux, macOS, and Windows, or if its free plan’s two channels and six hours recorded per stream suit the workflow better.

Vimeo is a better candidate when video hosting is central: its free plan includes one seat and 1 GB storage, while Starter provides one user, 2 TB storage, and 2 TB monthly bandwidth for $12 a month.

OneStream Live may fit scheduled broadcasts better: its free plan supports two destinations, 720p, one team seat, 1 GB storage, and three scheduled events.

Subsplash Church App is another church-focused option, with a free Subsplash Giving plan; card and ACH processing fees apply.

Church Online Platform is the alternative to consider when a church needs unlimited services and attenders, hosts, admins, chat, and prayers on a free service.

Livepush may suit web-only broadcasters who want up to 10 platforms at once and 20 streaming hours per month on its free plan.

BlizCast Radio & TV is another option for church communities, with a free Grace plan for up to 50 members and a pastor as sole admin.

BoxCast is a paid alternative with a free trial, for teams comparing dedicated streaming plans.

Verdict

Castream is a good choice for creators, churches, and other groups that want one mobile or desktop stream distributed to several destinations with chat, overlays, and recordings in the same service. Its strongest case is the combined workflow and the step from three destinations on Creator to five at 1080p on Pro. Look elsewhere if the free tier must support real broadcasts, or if a regular 1080p stream needs to cost less than Pro.
