FAQ

Common Questions

What is your minimum project budget for custom web apps?

Our custom web application projects start at ₹35,000, depending on scope and complexity. Simple MVPs start lower; enterprise applications are priced custom.

Do you use Next.js App Router or Pages Router?

We exclusively use Next.js 15 App Router with React Server Components for all new projects — giving you the best performance and SEO out of the box.

Can you build a multi-tenant SaaS platform?

Yes. We architect multi-tenant databases using PostgreSQL row-level security, Supabase, or custom schema separation strategies, depending on your isolation requirements.

Absolutely. Upon final milestone payment, you receive 100% of the source code, Git repository ownership, and all Intellectual Property rights.
