WEB APP DEVELOPMENT

Web apps with real business logic — built for production.

Custom web apps with multi-user access, role-based authorization, API integration and real-time data. Built on Next.js, React and Angular.

Why web apps with Kritm?

Past the standard corporate site — we build web apps with user management, dashboards, reporting, real-time notifications and complex workflows. For SaaS products, internal tools, B2B portals and admin panels we pair Next.js / React / Angular frontends with Node.js or Django backends. Design system, performance budget, observability and security are default on every project.

Frequently asked questions

Top web app questions.

What's the difference between a web app and a corporate website?

A site informs; a web app lets users log in and do things — dashboards, account management, data processing.

Can it integrate with our existing systems?

Yes. ERP, CRM, payments, email and others via REST or GraphQL APIs.

Do you build multi-tenant SaaS products?

Yes. Tenant isolation strategy (DB-per-tenant, row-level security or schema-per-tenant) is picked per use case.

How long does development take?

Simple web app: 6-8 weeks. Mid-complexity SaaS: 12-16 weeks. Enterprise portal: 16-24 weeks.

Is post-launch support available?

Yes. Monthly support plans ($1,500-$5,000/month) or a Dedicated Team model for ongoing development.
