Why teams bring us in

Your web app was built for 100 users. You now have 10,000 and it’s falling apart.
You need real user authentication, workflows, integrations, dashboards not a CMS.
The agency shipped a frontend. There’s no architecture, no testing, no way to scale.
Critical processes in Excel. It needs to be a proper web application.

You don’t need a website builder. You need engineers who build

production web applications with proper architecture.

What is Web Application Development?

Web application development is the process of building software applications that run in a web browser. Unlike static websites, web applications have dynamic functionality, user authentication, data processing, and business logic.

Common examples include SaaS platforms, enterprise portals, customer dashboards, e-commerce platforms, and marketplace applications.

COMMON QUESTIONS

Frequently asked questions

A website displays information (like a brochure). A web application has interactive functionality — user accounts, dashboards, workflows, data processing, and business logic running in the browser. If users log in, submit data, or manage workflows, you need a web application, not a website.

Yes — HST builds multi-tenant SaaS platforms with subscription billing, onboarding, role-based access, and API integrations. We’ve built SaaS for BSI (GDPR compliance) and CameraMatics (fleet management). SaaS architecture requires tenant isolation, billing, horizontal scaling. Our architect designs this from sprint 0.

A typical HST web app engagement starts from €5,000–6,000/mo per engineer for a managed pod, or €20,000+ for fixed-price projects with defined scope. Simple internal tools: €20–40K. Full SaaS platforms: €60–150K+ over 6–12 months.

HST primarily uses React (with Next.js) and Angular for enterprise apps, paired with TypeScript. Framework choice depends on your existing stack and project requirements. Greenfield: React/Next.js. Large enterprise apps with strict typing: Angular.

Yes — HST builds API-first web applications designed to integrate with SAP, Salesforce, Microsoft Dynamics, and legacy systems via REST, GraphQL, or event-driven architectures. Integration architecture is planned during discovery. Our architect maps all integration points before development.

Yes — every HST engagement includes cloud deployment on Azure or AWS with CI/CD, monitoring, and production support. We offer ongoing maintenance plans. Your app is production-ready from sprint 1, with automated deployments, error tracking, and monitoring.
