Performance & Reliability

Whether you're working remotely or learning online, Cosmos understands that you need a platform that supports extended use without technical frustrations. We built Cosmos from the ground up knowing that students and professionals would be using it for several hours a day, with the platform always running in the background of their digital lives.


Cosmos delivers enterprise-grade performance and reliability that keeps the platform running smoothly for all-day use. We've architected performance and reliability into the core of the platform, ensuring it works efficiently across all devices and network conditions without draining your resources.

  • Resizable, properly organised video — videos sit in a clean vertical stack, sized to fit your screen
  • Every control where you are — mic, camera, raised hand, home desk, and status all live inside the pop-out. No tab-switching mid-conversation
  • Auto-starts on screenshare — present and keep your team in view automatically. On dual monitors, hover the screenshare button to disable, or pop it back in from the top-right
  • Pop-out automatically expands when someone wants to talk to you — their video appears with mic controls and status options
  • One-click switching between multiple shared screens directly from the pop-out


Pop-out videos from Cosmos when you are working on other apps. Be in call with your teammates and access all call controls from pop-out.

  • 99.999% platform uptime with real-time status monitoring (Status Page)



Why it matters

  • Connect large remote teams seamlessly - As distributed teams grow, Cosmos enables everyone to come together in a spatial environment where you can change group participants rapidly, seeing people in under 50 milliseconds rather than waiting 30+ seconds for calls to connect.
  • Create true spatial presence - The technical speed and performance allows for genuine spatial experiences, making configurable virtual offices, campuses, and event spaces feel natural and responsive.
  • Use your existing hardware - Cosmos's tiered performance options ensure it runs efficiently on standard equipment without requiring expensive upgrades, making it accessible for both educational institutions and businesses.


Pro Tips

  • Use the desktop application with pop-out mode for the best performance during all-day sessions - it uses significantly fewer resources than browser-based access.
  • When sharing screens with colleagues or classmates, use the annotation tools to highlight important information directly rather than describing what you're referring to.
