Frequently asked questions
Didn't find an answer? Write to us — we'll reply within 24 hours.
Ask a questionHow much does it cost to create an app or website?+
We price each project individually, as the cost depends on the scope, complexity, and chosen technologies. After a free consultation, we prepare a transparent quote broken down into stages — with no hidden fees.
How long does it take to complete a project?+
A simple website can usually be completed in up to 7 days, while a more advanced web application typically takes 2 to 4 months. We work in short iterations, so you can regularly see the progress and influence the direction of the project.
Do I receive full rights to the code after the project is completed?+
Yes. Once the project is settled, we transfer full ownership of the source code to you, along with access to the entire infrastructure. We don’t make you dependent on us — the product belongs 100% to you.
Do you provide support after launch?+
Of course. After launch, we monitor the product’s performance, respond to requests, and continue developing it with new features. We offer flexible support packages tailored to your needs.
What technologies do you work with?+
We most often rely on a proven, modern stack: React, Next.js, and TypeScript on the frontend; Node.js, NestJS, and PostgreSQL on the backend; and Docker, Kubernetes, and AWS in DevOps. We always choose technologies based on the goals of each specific project.
Do you work with clients outside Poland?+
Yes, we deliver projects remotely for clients from Poland and abroad. We communicate online, regularly present progress, and make sure that distance has no impact on the quality of our cooperation.
