Web application development means building interactive software that runs in a browser — either server-rendered, client-rendered, or both. Unlike static sites, web apps handle authentication, data persistence, real-time updates, and real business logic. Built on Next.js with Supabase and Vercel, they perform like native apps while staying as deployable and accessible as any website.

Häufige Fragen
How long does it take to build a custom web application?
Most production-ready web apps take 8-12 weeks from architecture to launch. Simple MVPs and internal tools can ship in 4-6 weeks. Enterprise builds with complex integrations and compliance requirements typically run 12-16 weeks. Every project is scoped upfront — timelines are fixed, not guesses.
Why Next.js and Supabase instead of Ruby on Rails or Laravel?
Next.js handles server rendering, static generation, and API routes in one framework. Supabase gives you PostgreSQL with built-in auth, real-time subscriptions, and row-level security — no separate backend needed. Pair that with Vercel's edge network and you've got a stack that ships faster and scales cheaper than traditional monoliths. It's not trendy, it's just the right combination for the problems most SaaS and fintech companies actually face.
Can you build multi-tenant SaaS architecture?
Yes. Multi-tenancy gets implemented at the database level using Supabase row-level security policies. Each tenant's data is isolated — no cross-contamination, no "oops we showed the wrong customer's records" incidents. It supports shared-database multi-tenancy for cost efficiency while still giving you enterprise-grade data separation and per-tenant configuration.
What does OWASP compliance mean for my web app?
We audit every build against the OWASP Top 10 — the industry-standard list of critical web application security risks. That means SQL injection, broken authentication, cross-site scripting, SSRF, and the rest of the usual suspects. Automated scanning runs in CI/CD so vulnerabilities get caught before code ever reaches production. It's not a one-time checkbox, it runs on every deploy.
Do you build Progressive Web Apps (PWAs)?
Yes. PWAs get built with service workers for offline capability, web app manifests so they're installable, and push notification support. Users can install your app straight from the browser — no app store review process, no 30% cut to Apple. A Next.js PWA gives you near-native performance with a single codebase to maintain.
What's included in the 30-day post-launch support?
Bug fixes, performance tuning, and minor adjustments based on what real users actually do. We monitor error rates, Core Web Vitals, and server logs. If something breaks or underperforms after launch, we fix it at no extra cost. This isn't a retainer — it's just accountability for what we shipped.
