Frequently Asked Questions

Plain talk on topics that matter to CTOs and IT managers.

Who owns the source code after project completion?

expand_more
After project completion and full payment, intellectual property transfers 100% to you. We build on open-source frameworks like Laravel and Next.js to deliberately avoid vendor lock-ins.

How do you ensure performance and reliability?

expand_more
We host business-critical applications on redundant cloud infrastructures. With automatic load balancing via Laravel Forge and Vercel Edge Networks we guarantee maximum availability even during traffic spikes.

Do you also take over existing codebases (legacy code)?

expand_more
Yes. As part of a technical code audit we analyse your platform and often recommend a gradual migration (Strangler Fig Pattern) to a modern architecture without downtime.

Which backend technologies do you primarily use?

expand_more
Our focus is on the Laravel ecosystem: Filament and Livewire for secure admin panels, Next.js (React) for complex web frontends. Also Node.js, Python or Go if needed.

What does an enterprise web app cost at HELITS?

expand_more
Entry projects (MVP, focused scope) start at approx. €20,000. Full enterprise applications with complex business logic, multiple integrations and admin backend range between €50,000–€150,000. After a free potential analysis you receive a binding fixed-price offer.

Can HELITS add AI features to a web app?

expand_more
Yes. We integrate large language models (OpenAI, Anthropic) directly into web apps – for AI search, automated document analysis, chatbots or decision support. Data processing optionally via EU servers or on-premise models – GDPR-compliant.

Does HELITS also offer hosting and operations after launch?

expand_more
Yes. We operate web apps on managed cloud infrastructure (Hetzner EU, Vercel, Cloudflare). Our operations model includes monitoring, automatic backups, SSL certificate renewal and incident response. SLA response times from 4 hours in the priority tier.
