About Service

One team from product design to a working web app

We take web products from idea to launch in one coordinated process. Our team designs the UX and UI, builds the frontend with React, Next.js and TypeScript, and works with trusted engineering partners on the backend (Node.js, Python, Supabase or Firebase) and cloud setup. Cosmos Studio stays responsible for scope, timeline and quality. We have designed and developed education platforms such as Povir, TALIS and EdWay, and we build SaaS dashboards and admin panels for B2B products.

Real-time collaboration

Hey!

We have an idea for a SaaS. Where do we start?

Hi Philip!

With a short discovery: users, core flows and the smallest version worth launching.

FAQ

Answered questions

1

Do you build the whole web app or only the frontend?

We design the product and build the frontend in-house. Backend, infrastructure and complex integrations are delivered with trusted engineering partners, and Cosmos Studio manages the whole project, so you work with one team.
2

Which technologies do you use?

Frontend: React, Next.js, TypeScript and Tailwind CSS. Backend through partners: Node.js / TypeScript, Python, Supabase or Firebase, depending on the product.
3

Can you build an MVP quickly?

Yes. We define the smallest version worth launching, design it and build it in phases, so you can test with real users early.
4

How long does web app development take?

An MVP usually takes 8–14 weeks from discovery to launch. Larger platforms are built in phases with a release every few weeks.
5

Can you work with our in-house developers?

Yes. We can design and build the frontend while your team owns the backend, or hand over a coded design system your developers continue with.
6

Which platforms have you developed?

Education platforms Povir, TALIS and EdWay, plus dashboards and admin panels for SaaS products. See the case studies for details.
