Web development company in India for SaaS, SEO, and high-performance products

Xenotix Labs is a web development company in India that ships Next.js applications for SaaS startups, content platforms, e-commerce brands, and SEO-first marketing sites. Our default web stack is Next.js (App Router) with React 19, Tailwind CSS 4, and Server Components. We pick this stack because every other framework we evaluated either gave up SEO performance for DX, or vice versa. Next.js with SSR + ISR + selective client hydration is the only stack that gives a startup both engineering velocity and Lighthouse 90+ on mobile.

Our web work falls into four shapes. SaaS products — Learners Capsule, Eazybizzy, Growara dashboards. Content/SEO sites — Pacific Holidays India, Gradlers, GoldenOak (each ranking on competitive education / travel / real-estate keywords). E-commerce — Nursery Wallah, Axmile, Bhaw Bhaw, Swaadm storefronts. Admin panels paired with our mobile apps — every Xenotix mobile build ships with a Next.js admin (Veda Milk, Cricket Winner, ClaimsMitra, Cremaster, etc).

For founders evaluating a Next.js development agency: ask the team to show you a Lighthouse run on a production page they shipped. We will. Our Pacific Holidays India site scores 95+ on mobile performance. Our Gradlers landing page is built around Core Web Vitals as a primary metric, not an afterthought. Performance is a function of architecture, not optimization passes — and architecture is what you are hiring for.

Tech stack reasoning

Why Next.js + React Server Components + Tailwind 4 is our default web stack

Next.js App Router with Server Components is the only stack we have shipped that delivers both Lighthouse 90+ on mobile and the developer velocity venture-funded teams need. Server Components keep large dependencies off the client bundle. ISR gives us static-class performance for content with database-class freshness. Streaming SSR means time-to-first-byte stays low even when data fetches are slow.

Tailwind CSS 4 with CSS variables means design tokens flow from Figma to production with zero drift. We pair this with a small in-house component library — never a bloated UI kit — so every component is auditable and the bundle stays under budget.

Backend is Node.js (Fastify or Next.js API routes for simple cases), PostgreSQL primary, Redis for cache and rate-limit, S3 for blob storage, CloudFront for CDN. Every line of infrastructure is Terraform — no AWS console clicks. We use Vercel for marketing-class sites and AWS ECS Fargate for any product where we need full control over networking, secrets, and scaling.

Common Questions

Frequently Asked Questions

Everything you need to know about web development services

Why Next.js over plain React or Vue?

Next.js is the only stack that gives you Lighthouse 90+ mobile performance, perfect SEO via SSR, and engineering velocity at the same time. Plain React is great for SaaS dashboards but loses on SEO. Vue / Nuxt is fine but has a thinner ecosystem. We have shipped on all three and Next.js wins for venture-funded products.

How much does a Next.js website cost in India?

Marketing site: ₹3-6 lakh. SEO content hub: ₹6-12 lakh. SaaS web app: ₹12-30 lakh. E-commerce or marketplace: ₹15-40 lakh+. Full tier breakdown above.

How long does Next.js development take?

Marketing site: 4-6 weeks. SEO content hub: 6-10 weeks. SaaS web app: 3-5 months. Marketplace: 4-7 months.

Can you migrate my existing site to Next.js?

Yes. We have done React/Vue/Wordpress migrations with measured Lighthouse delta of +30-50 points. Includes URL preservation for SEO.

Do you handle SEO and Core Web Vitals?

Yes — we treat SEO and performance as architectural concerns, not post-build add-ons. Schema, SSR, structured data, internal linking, Lighthouse 90+ are all baseline.

Will you deploy on Vercel or AWS?

Vercel for marketing-class sites where DX and edge-network speed matter. AWS ECS Fargate for SaaS products where we need full control over networking, secrets, scaling. We will recommend based on product shape.

Can you build admin panels?

Yes — every mobile app we ship pairs with a Next.js admin. ClaimsMitra has 114+ REST endpoints on its admin alone.

Do you provide hosting and maintenance?

Yes. We offer managed AWS deployment with Terraform-versioned infra, plus monthly maintenance contracts including dependency updates, CVE patching, and Core Web Vitals monitoring.
