Possible disadvantages of Kosmi

  • Limited Feature Set
    Compared to dedicated applications like Zoom or Discord, Kosmi may lack some advanced features like detailed administrative controls, reaction emojis, or integration with third-party apps.

    Real-time features such as video and voice chat can be bandwidth-intensive, potentially causing issues for users with slower internet connections.
  • User Interface
    Some users may find the user interface less intuitive compared to other platforms, which could result in a steeper learning curve for newcomers.
  • Security Concerns
    As with any online platform focusing on real-time communication, there are potential security concerns like unauthorized access to rooms if the invitation links are shared publicly.

Questions & Answers

As answered by people managing Kosmi and Nexty.dev.

What makes your product unique?

Nexty.dev's answer:

Nexty's greatest strength is its business completeness and modular design. It not only includes comprehensive authentication, payment, content management, and AI functionalities, but importantly, all features are integrated into cohesive business workflows. You get immediately usable paywalls, user permission controls, quota management, and other core commercial features that let you focus on product innovation rather than infrastructure.

How would you describe the primary audience of your product?

Nexty.dev's answer:

Our Primary Audience Falls Into Three Key Groups:

  • Solo entrepreneurs and indie hackers who want to launch fast without getting bogged down in technical setup
  • Small development teams (2-5 people) building their first or next SaaS product
  • Experienced developers who are tired of rebuilding the same authentication, payments, and AI integration from scratch

What They All Share:

  • They value speed over perfection in the early stages
  • They understand that time is money - especially when validating ideas
  • They want modern tech but don't want to spend weeks figuring out how to make it all work together

The Sweet Spot:

  • Developers with some Next.js experience who know enough to customize but don't want to start from zero
  • People launching B2B SaaS tools rather than consumer apps
  • Teams that need to show progress to investors or stakeholders quickly

Basically, if you're thinking "I wish I could skip the boring setup stuff and get straight to building my unique features" - you're our target audience.

Why should a person choose your product over its competitors?

Nexty.dev's answer:

It's Simple - We Actually Ship Products, Not Just Code

  • Most competitors give you boilerplate that breaks when you try to customize it
  • Nexty is battle-tested - I've used it to launch real SaaS products that generate revenue
  • You get working features, not "TODO: implement this yourself" comments

Speed That Actually Matters:

  • While others take weeks to set up properly, Nexty deploys in under 30 minutes
  • Everything works together out of the box - no integration nightmares
  • You're making money while competitors are still debugging their setup

Modern Stack Done Right:

  • Next.js 15 + React 19 with all the performance benefits
  • Built-in AI integration that actually scales (not just ChatGPT wrapper demos)
  • Three business models supported: SaaS, tools, and content - most templates only do one

Real Documentation:

  • Written by someone who actually builds with the template
  • No missing steps or "figure it out yourself" gaps
  • Based on launching multiple successful products

The Bottom Line:

Other templates are academic exercises. Nexty is a business accelerator built by someone who's shipped real products and knows what actually matters when you're trying to make money online.

If you want to build a business, not just learn to code, Nexty gets you there faster.

What's the story behind your product?

Nexty.dev's answer:

I'm a developer with over 5 years of experience in the software industry. In my day job, I mainly focus on Web frontend and Node.js development.

Since 2023, I've dedicated all my spare time to researching indie development and SaaS products. I've absorbed vast amounts of information and experimented with many tech stacks, with a simple goal - to find the most suitable full-stack technical solution for indie developers.

The tech stacks I've researched and practiced include but are not limited to: - Full-stack frameworks: Next.js, Nuxt.js - Styling & UI: Tailwind CSS, Shadcn UI, NextUI - Authentication: NextAuth, Supabase, Firebase, Clerk - Payment solutions: Lemon Squeezy, Stripe, Paddle - AI features: Direct AI model calls, Vercel AI SDK - Databases and ORM: Supabase, Firebase, Vercel Postgres, Upstash(Redis), MongoDB, Prisma - File storage: Cloudflare R2, Vercel Storage - Deployment: Vercel, Cloudflare, Dokploy, Zeabur, Railway, VPS - Email services: Resend, Unsend, MailChimp

During this process, I've shared insights through my blog and open-sourced several different types of project templates. I'm honored to have received recognition and support from many developer friends.

Through continuous practice and refinement, I've finally condensed this experience into a complete full-stack development solution, which is now the Nexty.dev template.

Kosmi Reviews

  1. Makaiya Williams

    There is this admin Foxiul, at first, he seemed like a pretty decent human being. But then all that changed. He got power-hungry. He started deleting messages, banning people from the lobby, destroying rooms, etc, etc. He banned my friend because she was sticking up for her younger sister, then banned me because he was in a bad mood when I simply said "Lol". He is turning Kosmi into a not-so-well-liked platform. many people are planning to leave Kosmi. I will be doing the same.

  • [NO SPOILERS] Invitation for Arcane online WATCH PARTY this weekend
    So if enough people comment here and are down to watch, I'm gonna be hosting the watch party on Kosmi. As I explained in the last post, Kosmi is a website to screenshare, so I'm gonna create the stream from there and we can all watch together. Source: almost 3 years ago
  • USA ... EU... Is there a TV / or method for watching together?
    Go on sl and buy a Kosmi TV. Or just use the webpage url on any prims media. https://kosmi.io/ It basically streams any browser wondow with w/e show on it. And it's real time. We have a Kosmi TV n watch any streaming service or movies together on it. Source: over 3 years ago
  • How do you watch movies long distance?
    Kosmi.io worked for us so far. But I'm planning to set-up our own instance of neko (https://github.com/m1k1o/neko) to give that a shot. Both are essentially browsers hosted in the cloud. So that has the advantage, that only one streaming account is required. Source: over 3 years ago
  • How can I stream PC games to a local TV for my wife to watch me play?
    True. I guess I was thinking that if maybe they were in the same room. And you could use the audio from the TV. People mentioned discord, but I feel like you could use the TV browser and just use https://kosmi.io/. Source: over 3 years ago
  • SURL/LM for a public location using the Kosmi TV?
    It's totally different from the other inworld TV's in that it's designed around kosmi.io for sharing streams and other things from one's local computer. You can use it, for example, to play a Netflix or HBO movie on the Kosmi TV so people inworld can also see it. Source: over 3 years ago
