Hey Product Hunt! 👋 MD here, founder of DualStream, with my co-founder John (Tangent on Twitch where he's been Partner for over 13 years). Quick story on how this got built, because the origin actually matters:
I have spent 20+ years building digital products. For a big chunk of that time I've watch streamers as a sort of background environment while I code or design, I love chat and being a lurker. For most of that time, I watched streamers I know describe their setups in horror: plugin duct tape, multi-streaming nightmares, software so complex they'd lose entire weekends to it. The same stories, year after year.
A while back I reached out to Tangent - I'd been a chatter of his since the days of No Man's Sky drops - and asked if he'd be willing to test out some prototypes I was playing with about a better way to multi-stream. He said yes, and then walked me through everything streamers actually deal with. The list was long. We started talking to other streamers. The list got longer. Their wish lists were specific, repeated, and almost never met by the tools on the market.
Those conversations became DualStream.
A note before the pitch: OBS is one of the greatest open-source projects of the last 20 years and the foundation that taught most of the streaming world how this all works, we have nothing but love and respect for OBS and the dedicated team behind it. DualStream isn't here to replace it. We're here to be the next thing - for creators who want a different path. Every creative field got its intuitive layer (Squarespace, Canva, CapCut). Streaming was the last one waiting.
DualStream is one studio that streams to your Desktop and Mobile audiences at the same time - same sources, arranged for each scene, live everywhere in one click. The DualStream Relay - one upload from your PC, live on every platform from our servers. And if your connection drops mid-broadcast, Relay keeps every platform live on your standby screen and picks back up the moment you reconnect. Native Alerts, Per-Source audio control, VTuber support, instant replay clips (horizontal and vertical), cinema grade effects, pop-out multi-platform chat and so much more is all built in.
The app is free to download - build everything, test offline, go live to one channel. Premium is $9.99/month for access to the DualStream Relay, multi-format recording, water-mark free clips and streaming to more then one channel at a time.
🎁 For Product Hunt: use code PH-3M-HI6NIX at checkout and your first 3 months of Premium are free (or just go to dualstream.gg/ph, its applied automatically that way).
We're a three-person team shipping every two weeks, and we genuinely build what users ask for. We'll all be here all day in the comments. Ask us anything, about the product, the build, the streaming category, the design process, the streamer feedback that shaped it, whatever. Genuinely grateful for your time!

Oh! Fun little P.S. ~ We also just released our first Open Source project for DualStream: An MCP server! This server lets AI assistants like Claude operate your DualStream studio: switch scenes, save instant-replay clips, build entire scene layouts from scratch, restyle your alerts and widgets, and react to what happens on stream. Everything runs locally on your machine, with your explicit approval, and every change renders on both your desktop and mobile canvases. Check it out here.
Simultaneous desktop + mobile streaming is a great use case for hybrid content creators. Does it sync audio/video timing automatically, or is manual alignment still needed?
DualStream
@ark_y_k Hey there! Audio is synced by default, and DualStream allows you to set every audio source manually! If you are audio savvy you will find a lot of flexibility in how you can be selective with your sources. If you want a more simple approach, you can do catch all audio with desktop audio as well.
One more great feature is that every audio track can be selected to be excluded from VOD's so that when fans are watching your videos you won't get hit with DMCA's for playing copyright music because it will not save or appear in the recording, enabling you to enjoy music with your live audience and not risk your videos being taken down after your platform of choice saves them for casual viewing!
@tangenttv Appreciate the detailed answer! Manual control over every audio source sounds powerful for people who need precision. Is there a "safe default" setup you'd recommend for someone just getting started, before diving into manual tweaks?
DualStream
@tangenttv @ark_y_k Hey Yuki! DS is designed to have really reliable defaults, my goal is to have it so you can just open it up and start streaming and not have to worry about manual controls (but they're all there if you want them!). So the "safe default" is honestly, just the default haha :)
How does the disconnection protection actually work? Does it buffer on your servers or keep something local? That's genuinely useful if it can hold a stream alive for even 30 seconds, but I'm curious what happens if someone loses internet completely.
DualStream
@talhakhalidmtk Great question! Right now what happens when internet drops is we play a "Standby" slate - a looping video. You can define what media (image, gif, video) is played or use our default. Your stream actually never goes down, we maintain your connection to the platforms via our relay system and the moment your connection is back, we start broadcasting your stream again. I'm actively working on improving this system to include components like live chat and clips playback automatically, so all the stream would lose while you're disconnected is your actual live A/V, but the rest could remain up while you sort out your internet.
The cross-platform streaming idea is solid, especially with that disconnection protection built into Relay. One thing that would really level it up is a built-in collaborative editor where co-hosts can queue clips, soundboard cues, or scene changes in real time without needing a third-party tool like Streamdeck. It would make multi-person streams feel way smoother.
DualStream
@gkhanyurdam5oq We have streamdeck integration and it is growing in features every day! We also have an incredible portal system that allows you to connect to another DualStream user and pipe their camera and audio directly into YOUR stream! It will make everything from podcasts to collabs incredibly easy.
A collaborative co host itself is something we have been considering as well, so we are of a similar mind!
DualStream
@gkhanyurdam5oq Great feedback and idea Gökhan! We have a beta system we call Portal built into DualStream that allows users to send their A/V to other DualStream users via a shortcode, sort of like joining someones co-op game. Adding in collab edit tools would be a great addition, we'll be looking into this!
The multi-platform chat pop-out is great, but it would be super helpful if there were a way to set per-platform chat moderation rules so I don't have to ban the same spammer three times across Twitch, YouTube, and Kick.
DualStream
@fcalapverd79575 Love that idea! Our entire cross-platform lives on a relay I built, so building in custom rules like that is totally possible and would make a great feature, we'll add it to the list! Appreciate you!
DualStream
Greetings Product Hunt! I am John, co-founder of DualStream! I am a full time live streamer on Twitch with 13 years of Partnered, full time experience on the platform with 230,000 followers under the online handle 'Tangent'. I started streaming as a passion hobby once I discovered such things existed and I was instantly hooked. Over a decade later I am still here and have experienced every up and down a creator can imagine!
In that time the content creation space has evolved and changed (And grown exponentially!) in ways many creators might not expect! One place that has never changed though? The reliance on open source OBS for operating what 99% of the streaming world utilizes.
My contributions to DualStream are in the features I feel that content creators of all sizes not just want, but absolutely need in todays ruthlessly competitive streaming space. MD can handle the technical side of things, but if you are a content creator; a dreamer just starting out with a hobby or an experienced content creator hearing a streamer's perspective is, read on my friends!
OBS is responsible for giving me and many of my peers the careers that we have had and enabled us to turn hobbies into careers. OBS was never intended for live streaming, but with a little creativity and understanding of its (confusing) settings, we have been able to fit it to what we need.
But that is one of the big challenges of OBS! It is robust in the hands of somebody who is technically experienced with the software, but to a new user it is a daunting trial and error experiment. Multi streaming has been the recent hot topic people have been trying to crack in the last few years. If you want to branch your stream from Twitch to Youtube, Tiktok, Kick, etc AND have both a vertical feed for phones and a horizontal for PC users, you have to jump through many hoops to make this possible.
OBS is capable of doing these things, but requires the use and understanding of plugins and mods, all of which are designed by good (usually, there have been security issues) intentioned users. The specific installation instructions and settings required to use many of these plugins results in frustrations and radical changes to the OBS UI. On top of that, it bloats the OBS software and makes it perform in unexpected ways depending on your PC setup. You shouldn't have to have custom docks installed and complicated modifications to your streaming software to branch your stream out in 2026.
When Twitch removed their no compete clause on multi streaming, the wild west once more opened up to creators. The push to crack the easy multi streaming code was the hot topic. For OBS, this meant bigger bloat, more plugins, worse PC performance, many crashes, and a lot of experimentation. For a new streamer you can afford to make mistakes and adapt to the multitude of glitches and crashes if you mess it up, but if you are a full time caster where your mortgage payments are reliant on you keeping your content schedule steady and professional, this can be harrowing!
Remember where I mentioned OBS has 99% of the market for users? Well, all of the innovations for multi streaming (And everything else) began flowing through OBS. The industry decided that the best way to cash in on this, was to bloat OBS even more, and design entire companies and software around utilizing the already strained OBS systems simply because it was so prevalent in the space. Virtually nobody has innovated streaming software from the ground up, too concerned about leaving the security of the confusing, bloated, and increasingly expanding software just because the assumption was that everything must be tied to OBS. The companies that did try to make their own software charge ridiculously high prices for essentially what OBS does with a somewhat more simple approach.
This is where we come in! MD has been a long time viewer of mine in my twitch channel, and witnessed me having some extreme problems with OBS. Crashes, disconnects, encoding problems, multi stream failures. At one point Twitch kept closing my connection to OBS mid cast due to a problem with OBS that would require them to patch it out, leaving me helpless for months.
He approached me and offered to build me a private connection to Twitch, my own personal streaming software because he was very kind and wanted to help me. He built me a very simple, but extremely effective piece of software that proved to be incredibly stable. He asked me if there was any features that I would like to have on it, and this turned into multi hour brainstorming sessions about the industry and tools that I need for my content.
This would eventually become DualStream. I was so floored by MD's ability to implement my requests (And I have a lot of them!) so quickly and so simply that the discussion started to steer in the direction of "If this is helping me so much, it has to be able to help others too."
In no time we had a complex streaming software that was so SIMPLE to use that required ZERO plugins or modifications and sidesteps virtually all of the pain and agony associated with trying to multi stream in multiple formats. I have been using DualStream exclusively for thousands of hours and proudly use it every day for my live streams. I entrust my financial wellbeing as a full time creator in DualStream to put my money where my mouth is. Without wanting to sound cocky, I have had more financial success in the last year of utilizing DualStream on my casts than previous years with OBS, even with the bumps in the road of developing the software and live fire testing it on my live streams.
But it isn't just the raw ability to reliably connect. It is all the fun features for interacting with audiences, manipulating your feed with special effects and on screen novelties that normally require browser sources and many plugins to use. We even have a fully customizable on screen Alerts that offer more customization that Streamlabs and Streamelements without the need of coding knowledge (And it is less taxing than using browser sources.. Though we have browser sources available as well of course!). A lot of streamers don't realize that browser sources are TAXING on your system and the reason every streaming software utilizes them is because the streaming world is chained to OBS and everyone is too scares to take the chance on innovating and those that do see even small creators as cash cows and will charge very high prices knowing that there are no better options.
So that's it! DualStream is a from the ground up approach to live streaming, designed by creators aimed specifically for creators, not merely by people trying to cash in on creators. I have not abandoned streaming to focus on DualStream, I am actively streaming 60+ hours per week and feel that if I am to properly guide DualStream in its future creator features that I will need to be on the front lines of content creation still.
If you have any questions about live streaming, the successes and failures (and risks!), or anything in the creation space as well as DualStream, please feel free to ask! Thank you for your time! - John / Tangent

The relay setup genuinely saved me when my internet flickered mid-stream, no awkward goodbye screens. Love that I can finally chat with both desktop and mobile viewers without juggling windows.
