OBS is free, powerful and completely unnecessary if what you want is to broadcast a video you already have. Upload the file, paste your stream key, and Streamza does the encoding and the RTMP push on its own servers — from any browser, on any device, including a phone.
Searches for "live stream without OBS" almost always come down to one of five walls:
If your goal is broadcasting a recorded video, every one of those problems disappears when the encoding moves off your machine.
OBS bundles four jobs into one program. Understanding the split makes it obvious which ones you still need:
| OBS does this | Do you need it for a recorded video? |
|---|---|
| Captures a camera, screen or window in real time | No — your video is already recorded. |
| Composites scenes, overlays and transitions | No — that belongs in your video editor, where you have more control anyway. |
| Encodes to H.264/AAC | Yes, but your export is already encoded. Streamza passes it through. |
| Pushes the result over RTMP to the platform | Yes — this is the part Streamza does for you, from the cloud. |
So for pre-recorded content, OBS is doing one useful job: opening an RTMP connection and pumping frames into it. That job does not need to happen on your hardware.
| OBS on your machine | Streamza in the cloud | |
|---|---|---|
| Install required | Yes | No |
| Works on a phone | No | Yes |
| Machine must stay on | Yes, the whole broadcast | No |
| Your upload bandwidth | Used continuously | Used once, during upload |
| Your CPU/GPU | Used continuously | Not used |
| Survives a power cut at home | No | Yes |
| Live camera and screen capture | Yes | No — recorded files only |
| Scene switching mid-stream | Yes | No |
| Setup time | Half an hour, first time | Under two minutes |
When you should still use OBS: if you need a live camera, live gameplay capture, real-time scene switching, guests, or overlays that react to what is happening right now, OBS is the right tool and Streamza is not a substitute. Streamza replaces OBS specifically for broadcasting video files — including the case where you use OBS to record and edit first, then hand the finished file to us to broadcast.
From YouTube Studio, Twitch Creator Dashboard, Facebook Live Producer or your platform's equivalent. The stream key guide lists them all.
Go to streamza.live/studio on a laptop, a tablet or a phone and claim a free live slot. No install, no account, no card.
Drop in your MP4. The RTMP URL is pre-filled for YouTube, Twitch and Facebook — for anything else, paste the server URL too.
The stream runs on our servers. Your browser is only the remote control, and you can shut it the moment the broadcast is live.
No encoding load, no thermal throttling, no dedicated streaming PC, no capture card. The laptop you already have is enough.
You upload once at whatever speed you have. The sustained outbound stream to the platform comes from our datacentre, not your router.
No scenes, no sources, no bitrate maths, no test streams to check for dropped frames. Two fields and a button.
Yes. Everything happens in the browser and on our servers. There is no download, no plugin and no extension — and because there is no local encoder, it works identically on Windows, macOS, Linux, Android and iOS.
Yes. Open streamza.live/studio in your mobile browser, upload a video from your camera roll, paste your key and start. There is also a separate Streamza Android app if you want live camera and screen streaming, which the web service does not do.
Generally better, because there is no second encode. OBS re-encodes your file in real time and quality depends on your CPU keeping up. Streamza relays your existing export, so the resolution, frame rate and bitrate you chose in your editor are what reaches the platform.
Same reasoning applies. They are all local encoders or live production suites built around real-time sources. For pushing a finished video file to an RTMP endpoint, none of that machinery is needed.
Not through the web service — it broadcasts video files. For live camera and screen capture, use OBS on a desktop or the Streamza Android app on a phone.
Yes. Anything that accepts an RTMP or RTMPS ingest URL and a stream key works, which is every platform OBS can reach. See custom RTMP streaming.
Upload your video, paste your stream key, and press go.
