Frequently Asked Questions
Why do startups choose Next.js for web development?
Next.js gives startups the best combination of developer speed, SEO performance, and scalability. Server-side rendering and static generation mean fast page loads and good search engine indexing out of the box. The App Router in Next.js 14 makes it easy to build complex multi-tenant SaaS apps. We use Next.js as our default for all web products because it reduces time-to-market without sacrificing performance.
How much does web development for a startup cost in India?
A marketing website with custom design and CMS (5–10 pages) costs ₹3–6 Lakhs ($4,000–$7,500 USD) and takes 4–6 weeks. A web app MVP with authentication, dashboard, and core features costs ₹2–8 Lakhs ($2,500–$10,000 USD) and takes 4–6 weeks. A full SaaS platform with multi-tenancy, subscription billing, admin panels, and API access costs ₹8–20 Lakhs ($10,000–$24,000 USD) and takes 8–12 weeks.
Can you build a web app that scales to thousands of users?
Yes. We design for scale from day one without over-engineering. We use Vercel or AWS for horizontal scaling, PostgreSQL with connection pooling (PgBouncer or Supabase), Redis for caching and rate limiting, and edge functions for global performance. We also design multi-tenant architectures that can handle 10,000+ tenants on a shared infrastructure without performance degradation.
Do you integrate payment gateways like Stripe or Razorpay?
Yes. We integrate Stripe for US/UK/global customers and Razorpay for Indian markets. This includes subscription billing, one-time payments, usage-based billing, metered billing, webhook handling for events (payment success, failure, chargeback), and customer portal for self-service plan management. We implement proper idempotency and webhook verification to prevent billing edge cases.
How do you handle authentication and user management?
We use NextAuth.js (Auth.js) for most projects — it supports email/password, OAuth (Google, GitHub, LinkedIn), magic links, and MFA. For enterprise needs, we implement Auth0 or Clerk with SSO and SAML. All authentication systems include session management, refresh token rotation, CSRF protection, and rate limiting on login endpoints.
