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
Entry When it pays off

Three signals for a custom web app.

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.
