How to Stream to Twitch and Kick at the Same Time

How to Stream to Twitch and Kick at the Same Time

If you're building an audience as a streamer, there's no reason to pick a single platform anymore. Twitch has the biggest live-streaming audience; Kick has looser rules and a revenue split a lot of creators prefer. Streaming to both at once means every hour you put in counts twice.

Castream lets you run this combo from your phone or through OBS. Setup takes about ten minutes, and after that it's two toggles every time you go live.

What you need

  • A Castream account
  • A Twitch account (you'll connect it with one login — no keys to copy)
  • A Kick account with streaming enabled (you'll need its stream URL and stream key)
  • A decent connection — wired or strong Wi-Fi if you're on desktop, solid Wi-Fi or 5G on mobile

Connect Twitch

Twitch is the easy one. Castream connects to it with OAuth, so there's no stream key to hunt down:

  1. Open the Castream app and go to Settings → Destinations
  2. Tap Twitch
  3. Log in to Twitch and authorize Castream when asked
  4. Save the destination

That's the whole thing. If you ever want the detailed version, there's a dedicated walkthrough: How to Connect Twitch to Castream via OAuth.

Add Kick as a custom RTMP destination

Kick doesn't have a one-click login in Castream, but it does give you RTMP credentials — and Castream supports custom RTMP destinations, which is all you need.

  1. Open Kick in a browser and go to your Creator Dashboard
  2. Find your Stream URL (server URL) and Stream Key — usually under Settings → Stream
  3. Copy both values
  4. In the Castream app, go to Settings → Destinations
  5. Add a Custom RTMP destination and name it "Kick"
  6. Paste the Stream URL and Stream Key, then save

Treat your Kick stream key like a password. If it ever leaks, regenerate it in your Kick dashboard and update the destination in Castream.

Going live from the app

  1. Tap Go Live in Castream
  2. Toggle Twitch ON
  3. Toggle Kick ON
  4. Set your title and category
  5. Tap Go Live

One stream leaves your phone; two platforms receive it. Your Twitch viewers and Kick viewers each see the same broadcast, and you only had to press the button once.

Going live through OBS

Running overlays, alerts, or a multi-scene layout? Route OBS through Castream instead of streaming to each platform separately:

  1. In Castream Web, confirm Twitch and Kick are connected under Destinations
  2. Copy your Castream RTMP URL and Stream Key from the dashboard
  3. In OBS: Settings → Stream, Service set to Custom, paste both values
  4. Start streaming in OBS
  5. In the Castream Go Live Dashboard, select Twitch and Kick, then click Go Live

This is the same pattern as our OBS + Castream guide — one ingest, many outputs.

Chat, alerts, and the practical stuff

The honest part nobody mentions: your chats are separate. Twitch chat and Kick chat don't merge. A few ways streamers handle it:

  • Keep both chats open — phone for one, monitor or second screen for the other
  • Use Castream Web's unified chat view to follow both in one place
  • Tell viewers upfront: "chat's on both sides tonight, I'll catch up between games"

A couple of settings notes for this combo: both platforms are happiest with horizontal 1080p at 30 or 60 fps — no aspect-ratio juggling like the vertical platforms demand. Kick is generally more forgiving on content rules than Twitch, so stream to the stricter platform's standards (Twitch's) and you'll stay safe on both.

Your first stream: a simple game plan

If this is your first time running both, keep it simple:

  1. Pick a 60–90 minute session. Long enough for both algorithms to notice, short enough to stay sharp.
  2. Open with the game and the plan. "Ranked grind tonight, road to Diamond — chat, tell me your rank." Viewers decide in seconds whether to stay.
  3. Acknowledge both chats out loud. "Twitch says go left, Kick says go right — democracy wins, we're going left." It takes five seconds and makes both audiences feel included.
  4. Take one break. Two hours in, five minutes off. Your regulars will still be there, and you'll stream better in hour three than if you'd powered through.
  5. Raid or redirect at the end. Send your Twitch viewers to another streamer with a raid; tell your Kick chat where to find you next. Ending deliberately beats just vanishing.

After three or four sessions you'll know which platform brings more chatters, more followers, more energy — and you can lean into it without abandoning the other.
