To multistream to Twitch, Kick and YouTube, send one feed from your streaming software to each platform's server URL and stream key, through either a multi-output plugin in OBS or a cloud relay, and follow three rule sets: the Simulcast Guidelines in section 11 of Twitch's Terms of Service, the Multistreaming toggle Kick requires of its Partners, and the bandwidth advice on YouTube's Stream across platforms page. All three allow simulcasting; they differ on what you must switch on, what you must keep off screen, and how much upload you need.
Below are the rules side by side, the conditions that catch streamers out, the setup options, and a checklist to run before every multistream. Which platform to build your channel on is a separate question, answered in our Twitch vs YouTube comparison for live streamers.
Is multistreaming allowed on each platform?
Yes on all three, with conditions. This is what each platform's own pages said on 1 October 2026.
| Platform | Allowed? | What you have to do | What breaks the rules | Source |
|---|---|---|---|---|
| Twitch | Yes, for every streamer unless a separate agreement with Twitch requires exclusivity | Give Twitch viewers an experience no worse than on other services, including how you engage with Twitch chat | Directing viewers to leave for your simulcast elsewhere, or showing merged chat and other combined activity on the Twitch stream | Terms of Service, section 11 and the Simulcasting Guidelines FAQ |
| Kick, Partner Program | Yes, to any platform; the Partner terms say the relationship is not exclusive | Switch on Multistreaming, found under Partner Income in your dashboard, or type /multi on in chat when you also stream to long-form platforms | Multistreaming to Twitch or YouTube with the toggle off, which the Partner terms treat as a breach | Kick multistreaming help and Partner Terms and Conditions |
| Kick, outside the Partner Program | Not restricted: no simulcasting clause appears in the Terms of Service dated 23 March 2026 | Follow the Community Guidelines that govern every Kick stream | Kick publishes no simulcast-specific restriction for channels outside the Partner Program | Kick Terms of Service |
| YouTube | Yes; its help centre calls the practice simulstreaming and publishes best practice for it | Keep a verified channel with live streaming enabled, accounts in good standing everywhere, and enough upload for all streams combined | Nothing specific to simulcasting; the usual Community Guidelines and monetisation policies still apply to the stream | Stream across platforms |
Two details matter more than they look. Twitch's FAQ tells you to contact Twitch Support if you are unsure whether an exclusivity agreement applies to you. Kick's multistreaming article says the feature is only for Partner Program streamers and says nothing about Affiliates, so check your dashboard or ask Kick support before a first session.
Twitch: picture quality, links and merged chat
The Simulcasting Guidelines FAQ explains the three conditions in Twitch's terms. Its example of a degraded experience is shrinking or otherwise degrading the video on Twitch so it looks worse than on other platforms. On promotion, it draws the line like this:
- Plain links to your social profiles in your About section or panels are allowed, including links to other live streaming platforms.
- Large banners or messages in your bio or panels that push people to watch your live stream on another service are not allowed.
- Broadcast titles, go-live notifications, QR codes and chat commands that send viewers to a live stream elsewhere are off limits too.
- Tools that combine chat from several platforms are fine for your own personal use, provided the combined activity never appears on your Twitch stream.
That last point is where setups go wrong, because merged chat is a selling point of multistreaming products; the Streamlabs Multistream page, for one, promotes Twitch, YouTube and Kick chat in one place. Read a combined chat on a second screen, never in a scene Twitch viewers see. If you slip, the FAQ says Twitch sends a warning before enforcement, and its Monetized Streamer Agreement explainer confirms Partners may simulcast under these guidelines and post VODs anywhere straight after a stream.
Kick: the Multistreaming toggle and your Partner pay
Kick's multistreaming article says Partners need the toggle on when they also stream to long-form platforms such as Twitch or YouTube, but not for short-form or vertical destinations such as YouTube Shorts, TikTok Live or Instagram Live. It sits under the Partner Income toggle in your dashboard, and /multi on and /multi off switch it from chat. The article says to turn it on after you start your stream; the Partner Program page says to enable it before going live elsewhere. Start Kick first, switch the toggle on, then start the other outputs, and you satisfy both.
The pay effect is worded three ways. Kick's help article says your payout will be reduced by 50% for the duration of the session. The Partner Program page says you will earn 50% of your usual revenue, and further down that multistreaming may result in a reduction by 50%. The binding Partner Terms and Conditions say only that revenue is calculated differently and may be reduced, and clause 5.3 calls multistreaming without the toggle a breach. Plan on the help article's firm wording and check your dashboard after a test session; how Partner revenue, subscriptions and KICKs pay out is in our guide to how Kick streamers get paid.
Read clauses 1.3 and 1.4 of those terms too. They describe the licence you give Kick over content you create while streaming as exclusive, perpetual and worldwide, even though clause 5.3 calls the arrangement non-exclusive, and Kick's general Terms of Service grant only a non-exclusive licence. If you sell, license or promise your streams or VODs to anyone else, ask a lawyer how those clauses fit together. Outside the Partner Program there is no toggle, and the Terms of Service, dated 23 March 2026, contain no simulcasting clause.
YouTube: what its simulstreaming page asks for
YouTube is the only one of the three with a help page written for multistreaming. Stream across platforms asks for a verified channel with live streaming enabled, accounts in good standing on every platform, and each platform's stream key and RTMP server URL. That page says enabling your first live stream takes at least 24 hours, while YouTube's encoder set-up guide says it may take up to 24 hours, so request access a day or more before your first multistream.
Its bandwidth rule is the most useful part: add the target bitrate of every stream, then aim for an upload speed of 1.5 to 2 times that total, and the page's own example turns streams of 6 Mbps and 4 Mbps into an upload target of 15 to 20 Mbps. YouTube's older streaming tips page recommends leaving only about 20% of your upload free. For multistreaming, follow the newer page, which is written for simultaneous streams and warns about shared connections. How YouTube live streams earn is covered separately in our guide to monetising YouTube live streams.
Plugin, relay or built-in: how the stream leaves your computer
The Stream page in OBS Studio's settings takes one server and one key, which is the page Kick's OBS guide walks you through, and built-in output to several services is still an open request on the OBS ideas board. That leaves three ways to reach Twitch, Kick and YouTube at once.
| Setup | How it works | Suits you when | Watch out for | Documentation |
|---|---|---|---|---|
| OBS plugin with several outputs | OBS sends a separate upload to each platform; the Multiple RTMP outputs plugin can reuse the main OBS encoder to save processing power or run its own encoders | You want maximum control and quality, your computer is powerful, and your upload covers every stream | Every added output uses more upload, and each plugin lists a minimum OBS version to check before you update OBS | Multiple RTMP outputs plugin and Aitum Multistream |
| Cloud relay service | You send one stream to the relay, and its servers copy it to each connected platform | You stream to more than two places, your computer is older or slows down, or your upload is the bottleneck | A third party holds your stream keys or account connections, and free plans come with limits | Restream bandwidth article and YouTube's cross-platform page |
| Streaming app with multistreaming built in | You connect each account inside the app and toggle on the platforms you want to reach | You would rather manage scenes, alerts and destinations in one program | Any built-in combined chat has to stay off the layout your Twitch viewers see | Streamlabs Multistream |
The “suits you when” column follows YouTube's own criteria for local and cloud encoding, including its point that cloud services suit anyone planning to stream to more than two channels. Restream's help centre says its relay uses the same upload whether you send to one channel or 20, which matters most when your connection is the weak link.
Encoder settings all three platforms accept
When several outputs share one encode, which is what a relay does and what a plugin's shared-encoder option does, that single stream has to fit the strictest platform. On the platforms' own pages, Kick is the strictest:
- Kick. H.264 only, constant bitrate (CBR) only, up to 8,000 kbps, 1920x1080 and 60 fps, with stereo audio at 48 kHz at most; it does not accept H.265 or variable bitrate, according to Kick's connection troubleshooting article.
- Twitch. The Broadcasting Guidelines suggest every broadcaster use CBR and list 6000 kbps for 1080p at 60 fps.
- YouTube. The live encoder settings page accepts H.264, H.265 (HEVC) and AV1 over RTMP or RTMPS, with CBR as the bitrate encoding.
An H.264, constant-bitrate stream at 1080p or lower, within Twitch's bitrate guidance for that resolution, meets all three pages. A shared encode also gives Twitch exactly the same picture as everyone else, so the degraded-video example in Twitch's FAQ cannot apply. Twitch's pages do not say how a separate, higher-resolution YouTube encode would be judged, so the cautious default is to keep Twitch's output at least as good as any other. Keyframe intervals, presets and other base settings are in our launch checklist for new streamers.
Multistream setup checklist
Run this list when you first set up and whenever you add a platform or change software. Each step depends on the one before.
- Check your contracts: any exclusivity agreement with Twitch, any sponsor deal that names one platform, and, as a Kick Partner, the licence clauses in the Partner terms.
- Copy each platform's server URL and stream key (on Kick, under Channel, then Stream URL and Key) and guard them like passwords, because Kick's help centre warns that anyone holding your key can broadcast to your channel. Reset any key you think has leaked.
- Request YouTube live access a day or more before the first multistream.
- Add up the bitrates you plan to send, multiply the total by 1.5 and by 2 as YouTube's guidance suggests, and confirm with a speed test using realistic motion and audio.
- Pick a plugin, relay or built-in app from the table, and download it only from the developer's own page.
- Set one H.264, constant-bitrate encode at 1080p or lower that fits Kick's limits, and never give Twitch a weaker output than another platform.
- Tidy your Twitch channel: keep plain social profile links, remove banners, panel messages, chat commands and notification text that point to your live stream elsewhere, and keep other platforms out of the Twitch title.
- Put any merged chat window on a second screen for yourself, never inside the scene going out on Twitch.
- As a Kick Partner, start the Kick stream, switch Multistreaming on or type /multi on, then start the Twitch and YouTube outputs.
- During the stream, watch the Stream health tab in YouTube's Live Control Room, the Session Health Status badge in Kick's Creator Dashboard and Twitch Inspector, and answer Twitch chat as actively as the others.
- If you drop the other outputs but stay live on Kick, type /multi off, since Kick ties the pay reduction to the multistreaming session.
- Confirm each platform keeps a recording: Twitch saves past broadcasts only once you switch storage on, YouTube archives streams shorter than 12 hours automatically, and Kick saves the VOD to your channel page when you stop.
After a few sessions, compare pay, chat and new followers in each platform's analytics before deciding to keep all three. If one platform clearly carries your community, the Twitch vs YouTube side-by-side helps you decide where to focus.
Limits of this guide
This guide reflects each platform's pages on 1 October 2026, and the rules move: Twitch's terms can be amended by posting a new version, and Kick's Partner pages already word the same rule differently. It is general information, not legal advice. Its limitations are sharpest where the platforms leave questions open: whether a higher-quality YouTube encode counts as a worse Twitch experience, how Kick's exclusive licence clause sits beside its non-exclusivity clause, and whether Kick Affiliates have any multistreaming duties. Plugins and relays are third-party products, so read their documentation and security terms before handing over a stream key. If a sponsorship, payout or your account depends on the answer, ask the platform's support team in writing and keep the reply.
