Next.js is the best framework for shipping SaaS products fast — server components, built-in routing, API routes, and a massive ecosystem of SaaS-specific tools. SaTekk builds production Next.js SaaS applications using the App Router, TypeScript, Supabase, Stripe, and Clerk — the stack that lets us move fast without cutting corners on performance, security, or scalability.

Frequently asked questions

Why Next.js for SaaS?+
Next.js provides the best balance of developer experience, performance, and ecosystem for SaaS products. Server components mean less JavaScript shipped to the browser, App Router handles complex routing patterns cleanly, and the ecosystem of tools (Supabase, Clerk, Stripe) all have first-class Next.js integrations. It's also the most LLM-code-friendly framework, which accelerates development.
Do you use the Pages Router or App Router?+
App Router for all new projects. It enables server components, streaming, and co-located layouts that make SaaS UI significantly cleaner to build. We're deeply familiar with its patterns — parallel routes, intercepting routes, server actions — and apply them correctly rather than fighting the framework.
Can you work with our existing Next.js codebase?+
Yes. We audit your existing codebase first, identify structural or performance issues, and then add features or migrate components as needed. We're comfortable working in codebases we didn't originate — and we leave them cleaner than we found them.
How do you handle database migrations and schema changes?+
We use Supabase migrations for all schema changes — tracked in version control, reviewed in PRs, and applied through a CI/CD pipeline. No ad-hoc SQL in production. We also set up Supabase's generated TypeScript types so database schema changes immediately surface as type errors in your codebase.
