Are you a creative agency or a creative freelancer? We need you.
We work in the model of two teams: one for creative work and one for technical tasks. Creative agencies handle the creative side, while we focus on software development. This teamwork lets us produce top-quality projects and helps agencies sell larger-scale, more challenging projects.

Who we are
Your dedicated team, working relentlessly on the growth of your projects and the stability of your key systems.
A custom software development and support company.
We’re here to solve the real problems companies face when managing digital projects: missed deadlines, broken communication, disappearing contractors, lack of responsibility, and painful support experiences.
Whether you’re a small business, a growing company, or an established enterprise — we build operational frameworks around your business to eliminate chaos, delays, and uncertainty.
The problems
you face today
Managing digital projects often feels like a constant battle. Deadlines slip. Communication breaks down. External teams disappear after delivery. Nobody takes real responsibility for results.
Support becomes a painful add-on instead of a natural part of the service. Whether you run a small business, a growing company, or an established enterprise, the problems are the same: chaos instead of clarity, patchwork instead of process, frustration instead of control.
Our answer:
CosmOS Framework
To solve these problems, we built CosmOS — our operational delivery framework.
CosmOS isn’t software — it’s how we run your collaboration. It aligns delivery, support, and growth management into one seamless orbit around your business. With CosmOS, you don’t just get a one-time project — you get an embedded IT partner, driving continuous development, elite support, and real scale.
You focus on growth. We handle the gravity.
How you win
with us
Your projects are delivered with cosmic precision: clearly defined scopes, predictable timelines, proactive communication, and full lifecycle support. You keep full visibility over progress.
You gain a partner who doesn’t disappear after delivery — we stay in your orbit, ready to solve problems before they even appear. Support isn’t an afterthought for us — it’s our DNA.
We take ownership from day one and act as an extension of your team, not just a contractor. That’s why our clients don’t just get projects done — they get stronger, faster, and more resilient.
Ready to take off?
Let’s build your future together.
Join us
Forget chaos. At Cosmonauts.dev, you join a focused rteam working on impactful software – with clear processes, AI-enhanced workflows, and real influence on outcomes.
We’re not just another dev shop. We operate as a streamlined network of experienced engineers, product thinkers, and solution architects who care about quality and long-term value — not just deadlines.
Our CosmOS framework removes typical blockers: context switching, unclear specs, endless meetings. You focus on delivering excellent code and smart solutions while staying in sync with the business goals of our clients.
We value autonomy, clarity, and innovation. Whether you specialize in backend, frontend, DevOps, or full-stack problem solving, you’ll work with people who know why they build software. And who are not afraid to say “no” when something doesn’t make sense for the project.
