How to Stream to Twitch and YouTube Using a VPS as an RTMP Relay
Streaming to multiple platforms simultaneously from your home internet connection puts huge strain on your upload bandwidth. The solution many streamers use is routing their stream through a VPS as an RTMP relay.
Here is what an RTMP relay is, why it helps, and how to set one up in 2026.
What Is an RTMP Relay
RTMP is the Real-Time Messaging Protocol used by streaming platforms to receive video. When you set up an RTMP relay on a VPS, your OBS (or other encoder) sends one stream to the VPS, and the VPS then forwards that stream to Twitch, YouTube, Kick, and any other platforms you want to reach.
This means your home connection only needs to support one upload stream instead of two, three, or four separate uploads.
Why Use a VPS for Streaming
A VPS running in a professional Data Center has a much more stable and faster network connection than typical home broadband. For 24/7 streams or IRL streams where network reliability matters most, a VPS provides the consistent uptime that home connections cannot guarantee.
The VPS also acts as a buffer. If your home connection drops briefly, the VPS can continue streaming using buffered data while your encoder reconnects.
Getting Your Twitch Stream Key
Your Twitch stream key is found in the Twitch Creator Dashboard under Stream settings. It is a unique identifier that tells Twitch which account to associate your incoming stream with. Never share your stream key publicly, as anyone with it can stream to your channel.
For YouTube, the stream key is found in YouTube Studio under Live streaming options.
Setting Up nginx-rtmp on a VPS
- Install nginx with the RTMP module on your VPS:
apt install nginx libnginx-mod-rtmp - Edit
/etc/nginx/nginx.confto add an RTMP block with your push destinations - Point OBS to your VPS IP with
/liveas the stream path - Set your Twitch and YouTube stream keys as push targets in the nginx config
- Restart nginx and start streaming from OBS
VPS Requirements for RTMP Relay
For relaying a 1080p60 stream, a VPS with at minimum 2 CPU cores and a 1Gbps network port handles the job comfortably. The actual CPU usage for pure relay (not re-encoding) is very low.
Space-Node VPS plans include 1Gbps network connections and are well-suited to running continuous RTMP relay setups. If you are looking to stream more stably and reach multiple platforms at once, a Space-Node VPS is a practical option to look at.
Quick 2026 Answer
How to Stream to Twitch and YouTube Using a VPS as an RTMP Relay works best when you keep the stream simple and stable first. Pick one output resolution, one bitrate and one ingest server, then leave it running long enough to catch drops. For a 24/7 stream, boring settings are usually better than pushing the highest possible quality.
Stable Stream Checklist
- Use CBR bitrate so the platform sees a steady stream.
- Set keyframe interval to 2 seconds unless the platform asks for something else.
- Keep CPU usage below 80 percent during normal scenes.
- Test the stream for at least one hour before calling it ready.
- Keep a fallback video or playlist ready if the source fails.
- Watch YouTube, Twitch or Kick health warnings during the first day.
What Usually Breaks
Most stream problems come from network jitter, overloaded encoders, bad audio levels or file loops that stop after one pass. A VPS helps when the home connection is unstable, but it does not fix a bad OBS scene or a playlist with a broken file.
For 24/7 channels, also check disk space and logs. Small errors can repeat for days and fill storage. A simple restart schedule and a health check can prevent a quiet failure.
Where to Go Next
For plan choice and settings, use streaming VPS plans, YouTube Live encoder settings, streaming VPS network stability. The best supporting visual is a real OBS settings screenshot, a stream health screenshot and a small flow diagram from source to VPS to platform.
Real Test Routine
The safest way to test How to Stream to Twitch and YouTube Using a VPS as an RTMP Relay is to run the stream as if nobody is watching, then read the health data. Do not judge the setup after five minutes. Leave it running long enough for network changes, playlist loops, audio drift and platform warnings to appear.
Start with one scene, one audio source and one destination. Use a modest bitrate that your VPS or home connection can keep all day. After the test starts, check dropped frames in OBS, stream health inside YouTube or Twitch, CPU use on the server and disk space if files are looping from the VPS.
If the stream fails, fix the first clear warning instead of changing every setting. A bitrate warning points to upload or encoder limits. A keyframe warning points to OBS output settings. Audio clipping points to gain staging. Random disconnects usually need network checks, reconnect settings and a fallback process.
When to Use a Streaming VPS
Use a streaming VPS when your home connection, PC sleep settings or local power are the weak part. It is especially useful for 24/7 music, ambient channels, event restreaming and SRT or RTMP relays. Keep the source files organized, watch logs and keep a backup playlist ready.
Screenshot or Generated Image Target
A useful supporting image for this page should show the actual setting, console, panel or workflow being discussed. Avoid a generic stock image if possible. A simple generated diagram is fine when it explains the flow better than a screenshot.
- Capture the main settings screen or config file.
- Add one close crop of the important value.
- Add one result screenshot after the fix or setup is working.
- Keep private IPs, tokens, emails and customer names hidden.
