Custom Web Apps
& Dashboards.

When the workflow in the standard tool doesn't fit, the team works around it — or we build a new one. Internal tools, customer portals, KPI dashboards, API-driven applications. Lean, fast, in your ownership.

→ Applications Where custom apps deliver

Three typical builds.

01

Internal dashboards

KPI overview, live metrics from multiple data sources (CRM, ERP, analytics, custom DB). Filters, drill-down, export. Tailored for your decision processes — not generic "BI tool" mishmash.

Stack: Next.js · Postgres · Recharts · Vercel / Hetzner
02

Custom internal tools

Workflow applications for your team: order processing, ticket system, approval flows, custom CRM. Replace 3–5 standard tools with one focused solution — that exactly maps your process.

Stack: React · FastAPI / Node · Supabase · Multi-User-Auth
03

Customer portals & web apps

Self-service portals for your customers: order status, ticket tracking, document upload, support chat. Reduces request volume, improves customer experience, consistently branded across the brand.

Stack: Next.js · SSO/OAuth · Webhook-Layer · CDN

→ Answers Frequently asked questions

What mid-sized companies ask first.

When do I need a custom web app instead of standard SaaS?

When the SaaS solution covers 70 % and the last 30 % are decisive. Heuristic: monthly license cost × 36 months vs. one-time build cost + 15 % maintenance yearly. From 50–100 internal users and specific workflows, custom typically pays off.

Which technologies?

Frontend: Next.js / React / Tailwind / shadcn-ui. Backend: Node.js / Python (FastAPI) / Postgres / Supabase. Hosting: Vercel / Hetzner / AWS Frankfurt. We choose stack per project — no rigid technology mandate.

What does a web app cost?

Strongly depends on scope. Simple internal dashboards: €12,000–25,000. More complex tools with auth, multi-user, integration: €35,000–80,000. Customer-facing web apps with high polish: €50,000–150,000. Fixed price from Phase II after discovery.

How long does a web app take?

Internal tool: 4–8 weeks. Customer-facing app: 8–16 weeks. MVPs for early validation: from 2 weeks. We work sprint-based in 2-week cycles with clear deliverables.

How does it continue after launch?

On request: maintenance contract (updates, bug fixes, small features) from approx. €800/month depending on complexity. Or you take over — code, docs, repository are completely in your ownership. No vendor lock-in.
