Castream vs Restream

TL;DRFast summary

Looking for a Restream alternative for mobile streaming?

Restream is desktop-first. Castream is built for creators who want to go live from their phone—no OBS, no third-party RTMP apps.

1
Native iOS/Android ingest: go live directly from your phone with no extra setup.
2
Unified chat replies that actually post: reply to YouTube, Twitch, and Facebook from one place.
3
Simple multistreaming: stream to multiple platforms at once without juggling tools.

A better workflow than Restream-style setups

Compared to other RTMP streaming services, Castream is much easier to use. Whether using OBS on a computer or the Castream app on iPhone or Android, it is a breeze. On Restream.io, videos are only stored for 15 days. With Castream, the retention window is 30 days, and we can download a live stream within a minute to reuse it later.

That is the exact wedge against Restream: easier setup across OBS and mobile, double the recording retention window, and faster turnaround when you want to reuse a finished live stream.

What is Restream?

Restream is a multistreaming platform that allows you to broadcast to multiple platforms like YouTube, Twitch, and Facebook at the same time.

It is mainly designed for desktop workflows, where you stream using OBS or a browser-based studio and send that feed to multiple destinations.

While powerful for studio setups, Restream can be limiting if you want to stream directly from your phone or handle streams on the go.
