Frequently asked questions

What's the difference between a website and a web application?

Websites are primarily informational — they present a company and its services. A web application is an interactive tool where users work with data — dashboards, SaaS platforms, CRM systems, e-learning portals, etc.

What technologies do you use?

Primarily React and Next.js with TypeScript on the frontend. On the backend Node.js, PostgreSQL (Supabase), REST and GraphQL APIs. For deployment Vercel, AWS or custom servers.

How long does app development take?

Basic application (MVP) 4-6 weeks, business application 2-4 months, enterprise solution 4-8 months. Depends on scope, complexity and number of integrations.

How does maintenance and support work?

After launch we offer 60-90 days of free support. Then you can use monthly SLA with guaranteed response time, regular updates and monitoring.

Can you connect the app to our existing system?

Yes, we regularly integrate with CRM (HubSpot, Salesforce), ERP systems, payment gateways (Stripe, GoPay), shipping services and other third-party APIs.
