Real-time video evolved, and so did nanocosmos, through more than 25 years of existence: from audio and video technology to real-time streaming that simply works, powered by MOQ (Media over QUIC) and cloud production tools.
nanocosmos was founded in 1998, and real-time video became the core of the business in 2015, when H5Live launched. Since then, it’s grown into a full real-time video platform with end-to-end control. The nanocosmos platform covers cloud live production for multi-branding as well as the complete streaming infrastructure, from delivery and playback to analytics and security. This is what customers running high-stakes live video actually needed next.
This article will cover what the nanocosmos platform is, how it got built, and where it fits depending on which real-time video use case you’re running.
Quick answer: nanocosmos is a real-time video platform for interactive live video. It combines nanoStream, for ultra-low latency delivery, security, and analytics, with nanoStudio, for cloud-based production and multi-branding, so diverse use cases like iGaming, live casino, horse racing, and corporate events teams can produce and stream from one connected system instead of stitching together separate tools.
What Real-Time Video Has to Get Right
The moment video stops being something people watch and starts being something people interact with, three things become non-negotiable: latency, reliability, and control.
A three-second delay on a highlight reel is a minor annoyance. A three-second delay on a live roulette table is a different problem, because the outcome is already decided before the player sees it and the interactivity is gone. A dropped stream during a webinar is recoverable. A dropped stream during a live auction is a lost bid. That’s the gap between watching and participating. It’s not about “how do we stream video,” but “how do we make interactive video behave like it’s happening in the same room even for a global audience.”
Most streaming stacks solve delivery and stop there. Interactive video needs more: security, visibility, and control that hold up at scale.
What nanocosmos Is
nanocosmos is a real-time video platform that closes the latency gap but also delivers more than just streaming. It covers the full arc of real-time live video for interactive use cases: multi-branding the content in the cloud, streaming it at ultra-low latency, and giving teams the control and visibility to run it with confidence, all from one place to engage global audiences. We handle that so partners can focus on running their business, not their streaming infrastructure, because we see ourselves as a partner in that business, not just a vendor supplying it.
We built the platform around two cores. The nanoStream handles real-time video streaming. nanoStudio includes cloud production tools such as Cloud-Based Chroma Key for multiple branded streams. Together, they cover ingest to output as one connected system instead of a chain of separate tools someone has to stitch together.
Two Cores: nanoStudio and nanoStream
nanoStudio is where content gets personalized and shaped before it goes live. This is the cloud production core. Its centrepiece is nanoStudio Chroma: cloud-based chroma key that lets you composite branded, multi-output video from a single green-screen feed. One feed in, several branded outputs out, all handled in the cloud.
- How to personalize your live stream with one green-screen: For instance, in a live casino, a single live dealer feed can go out under different regional brands, with different overlays and languages, without setting up separate physical production for each one. The compositing happens once, in the cloud, and the branded variations come out the other side. That’s a different way of producing content than the traditional model of a studio, a green screen, and a truck full of switching hardware for every output you need.
The two cores are designed to work as one system. A live auction house doesn’t think about “delivery” and “production” as separate problems. They think about how to get a clean, branded, low-latency stream in front of bidders. That’s the job nanoStream and nanoStudio do together, and it’s why the nanocosmos platform is built to hand off between them without a visible seam.
What is nanoStream?
nanoStream is where the full streaming workflow lives. From ingest to playback, it does more than move bits from A to B. Three things matter here, and they tend to show up in the same order customers ask about them.
- Streaming covers the whole path. Ingest over RTMP, SRT, WebRTC, WHIP, or MOQ, nanocosmos’s own global CDN, and playback through a browser-based, white-label player for your own brand to your audience. MOQ (Media over QUIC) is the primary delivery protocol, with H5Live as an automatic fallback. So every viewer gets the best experience without a visible switch. Adaptive bitrate streaming and automatic failover across redundant paths keep that experience steady even when viewership spikes or a node has an issue.
- Control is the security and intelligence layer. Features like Guardian blocks unauthorized copies with IP blocking, referrer, and CIDR-level access control, catching relay attacks at the edge before an unauthorized viewer can even connect. Signed, time-limited playback tokens and geographic or referrer restrictions enforce who can watch, from where, and for how long, which matters for regulated markets and licensed content alike. On top of that sits real-time Analytics: viewer counts, quality metrics, startup times, and geographic breakdowns that turn every stream into business intelligence a team can act on, not just a dashboard to glance at.
- Experience is what keeps the audience engaged. Live captions and translation, live replay, automatic recording and VOD, and thumbnails or motion clips generated straight from the feed for reuse elsewhere. All of it runs at ultra-low latency, because an engagement feature that adds delay works against the reason someone tuned in live in the first place.
How We Got Here
nanoStream is the core of what we do, and has been since 2015. As the market evolved and our customers grew, we evolved with them. We added analytics, security, and production tools along the way. We’ve now organized all of that into two cores, nanoStream and nanoStudio. Now it is easier to understand what we offer and how each part creates value. It’s a clearer way to tell the story of what we’ve been building all along.
That story starts earlier than most people expect. nanocosmos was founded in 1998, which puts video experience at the centre of the company for over 25 years.
The ultra-low latency player that the platform is built on, based on our own technology H5Live, launched in 2015 and became a patented technology. H5Live became the foundation of a full cloud platform. We built our own global CDN rather than depending entirely on third-party infrastructure, which is part of why latency stays low even at scale.
In 2025, nanocosmos became one of the first platforms to adopt MOQ (Media over QUIC), a protocol built for low-latency, interactive delivery even over challenging networks, because innovation in streaming technology matters. Besides that, H5Live is still very much in use. It remains the automatic fallback behind MOQ today, the same proven technology that’s been in production for over a decade.
Every addition has come from the same place. We listen to our customers, acting like a trusted partner, and building the answer. Security features against misuse and to prove compliance. Analytics to see what was actually happening on their streams, not just assume it. Production tools create branded output without building a studio. The platform keeps evolving and seeking innovation year after year.

You Get a Team, Not Just a Real-time Video Platform
Software handles the technical side of streaming. This means support ends up as the part that’s easy to overlook when comparing platforms on a feature list.
With nanocosmos, your problems and challenges are not only a support ticket queue. It’s 24/7/365 support with a 100% uptime SLA. All from a team that’s been solving real-time video problems for more than a decade. You’re not the first customer to hit whatever edge case you’re hitting, and that experience is part of what you’re getting alongside the platform.
That same team makes onboarding easy from day one, and stays with you well past it. It’s a personal relationship, not a handoff. The nanocosmos team guides partners every step of the way, from first integration through whatever comes up months down the line, with people who already know real-time video and your setup rather than a rotating cast of first responders.
Launching in a new market on a tight regulatory deadline, adding new tools, or catching a spike in concurrent viewers before it becomes an outage. These are the moments a platform’s documentation doesn’t cover. Having a team that’s already seen the problem matters more than any single feature. That’s the difference between buying software and having a partner investing in your stream staying up.
For Who It’s Built For
nanocosmos is built for the moment real-time video becomes interactive. When someone watching is also acting, betting, bidding, or deciding, and the platform has to keep pace with that in real time, not just play smoothly. That’s the thread running through every vertical below.
iGaming is where the stakes are clearest, because in live casino and betting, video isn’t a supporting feature. It’s the game. Latency and reliability directly affect trust, fairness, and revenue, which is why iGaming is nanocosmos’s flagship vertical. See how that plays out in practice on the iGaming and live casinos page.
Horse racing carries that same split-second requirement in the other direction. The race and the result have to stay in sync, on every device, through the exact moment viewership spikes right before the start. See how that plays out on the horse racing page
Corporate events need the same reliability at a different scale, streaming to global, often distributed audiences with compliance requirements that vary by region, and with captioning and accessibility increasingly a requirement rather than a nice-to-have.
Public events and government streaming carries its own bar for security and uptime. There’s no room for a stream to quietly drop mid-announcement.
Live auctions run on the same split-second trust as iGaming. Bidders need to see, in real time, that the item and the price on screen match what’s actually happening in the room.
Education and entertainment verticals lean more on production quality and audience experience. This is where nanoStudio’s branding and compositing tools do a lot of the work. From a university streaming branded lecture content to a broadcaster running multiple regional versions of the same live show.
Different verticals, same underlying requirement: video has to be fast, dependable, and controllable enough to build a business on. See the full breadth on the solutions overview.
