No template builders, no WordPress patchwork. Astra IT Solutions builds business websites, web apps and complex applications on a modern stack - fast, secure, search-engine optimized and designed for conversion.
What is professional web & app development?
Professional web and app development means building a website, web app or app individually with modern technologies such as Next.js, React and TypeScript - instead of clicking it together from prefabricated templates. The result: full control over performance, security, SEO and scalability.
Substance instead of slogans
Performance as the default
Server-side rendering, optimised images and a lean frontend, with Core Web Vitals as the target from the start. Speed is not a feature but a baseline requirement - for users and for Google.
SEO, GEO & AEO from line 1
Structured data (Schema.org), clean semantics, sitemap, meta architecture and a content structure that is also correctly cited by AI search systems like ChatGPT and Perplexity.
Conversion-driven UX
Clear user guidance, psychologically placed CTAs, mobile-first design. A website is a sales instrument - not a digital brochure.
Web apps & app development
Real-time dashboards, booking systems, customer portals, internal tools and Progressive Web Apps (PWA) that feel like native apps - full-stack development with clean architecture, API design and database modelling.
Accessibility & standards
WCAG-compliant implementation, semantic HTML, keyboard operability. Important for reach, legal certainty and quality.
Maintainable & documented
TypeScript, component architecture, CI/CD deployment and documentation - so the project is still extendable three years from now.
Typical projects
- Business websites with CMS integration
- Web apps, apps & customer portals
- Progressive Web Apps (PWA) for mobile & desktop
- Online shops & booking systems
- Campaign landing pages
- Relaunch & migration of existing websites
- Technical SEO & performance audits
Technology stack
Proven standards instead of exotics: every technology in use has a large ecosystem and long-term maintainability - so your project can still be extended in five years.

Frequently asked questions about web development
How much does a professional website cost in Vienna?
A starter website with up to 5 pages costs €1,490 at a fixed price, a business website with a page per service starts at €2,490; complex web apps start at €8,000. The exact price depends on scope, features and integrations. You get a written first assessment within 24 hours on business days - or use our project cost calculator first.
How long does website development take?
A business website typically takes 3 to 6 weeks, a complex web application 2 to 4 months. The schedule is fixed before the project starts and made transparent in milestones.
Do you also build apps?
Yes. Astra IT Solutions develops web apps and Progressive Web Apps (PWA) that run on smartphones, tablets and desktop - no app store required, with one codebase for all platforms. A PWA can be installed on the home screen like a native app, sends push notifications and works offline. For most business applications this is the faster and more economical solution compared to separate iOS and Android development.
Why Next.js instead of WordPress?
Next.js delivers significantly better load times, higher security and full design freedom without plugin dependencies. WordPress sites are more frequently affected by security vulnerabilities and slow down as plugins accumulate. For content editing, a headless CMS is connected that is just as easy to use.
Will the website be optimized for Google?
Yes, technical SEO is part of every project: structured data, sitemap, meta tags, Core Web Vitals, clean URL structure and semantic HTML. In addition, the content structure is optimized for featured snippets and AI search systems (AEO/GEO).
Do you also handle maintenance and further development?
Yes, optionally with a maintenance contract: updates, monitoring, backups, security patches and continuous development. Alternatively, the project is handed over fully documented.
