Next.js Development Company in India for Global Brands
Vellumarc is a Next.js-first agency. Every new project defaults to the App Router and server components — we reach for Pages Router only on legacy migrations where a full rewrite is out of scope. We ship marketing sites, SaaS dashboards, headless ecommerce storefronts, AI-powered apps, multi-tenant platforms, and real-time applications — all deployed on Vercel with environment-level preview URLs and atomic deploys. Our performance budget is non-negotiable: Lighthouse 95+ on every launch, verified before DNS cutover, not after. Pricing is quoted as fixed scope in USD — no surprise invoices, no hourly ambiguity. Weekly demos on Vercel preview URLs keep you in the loop from week one. Our India-based engineering team operates with US, UK, and AU time-zone overlap so you always have a same-day response window. Start with a free technical audit — we will tell you exactly what your current stack needs.
What we build with Next.js
Four shapes that cover most paid client work — from a marketing site to a multi-tenant SaaS.
Marketing & Landing Sites
Vercel-hosted marketing sites with Incremental Static Regeneration, MDX-powered content, and CMS integration (Sanity, Contentful, Payload). Every page ships at Lighthouse 95+ with Core Web Vitals green across all routes. Content editors update pages without touching code; engineers never hand-build blog posts. Ideal for agencies, SaaS marketing sites, product launches, and campaign pages that need both editorial flexibility and maximum performance.
SaaS Dashboards & Apps
Full-stack SaaS with authentication (Better Auth, Clerk, NextAuth), billing (Stripe subscriptions and usage-based), RBAC, Server Actions, tRPC, and real-time UI via WebSockets or Ably. We design the data model, the API layer, and the dashboard shell — then ship iteratively with weekly demos so your first paying customer does not wait for a big-bang launch.
Ecommerce & Headless Storefronts
Shopify Hydrogen storefronts, headless commerce architectures, and Next.js Commerce-based builds with Shopify, BigCommerce, or custom backends. Product pages are ISR-cached at the edge, cart interactions run client-side without page reloads, and checkout is embedded or redirected depending on compliance requirements. Edge functions keep time-to-first-byte under 100 ms globally.
Multi-Tenant & AI Platforms
Multi-tenant SaaS with per-tenant subdomains routed through Next.js middleware, isolated data at the database or schema level, and tenant-aware component trees. AI features integrate via the Vercel AI SDK — streaming chat UIs, server-side LLM calls with structured output, RAG pipelines, and tool-use flows — all rendered progressively so the user sees output immediately, not after a full round trip.

How we work
Five-stage process — discovery to launch to maintenance retainer.
Discovery
We start with your brief, success metrics, and design references. We define the performance budget upfront — target Lighthouse scores, Core Web Vitals thresholds, and acceptable time-to-interactive for your primary audience. Nothing moves to architecture until the success criteria are written down and agreed.
Architecture
We choose App Router vs Pages Router, plan which routes use SSG, ISR, or SSR, and design the data layer — ORM, database schema, API contracts. For multi-tenant or AI builds we design the tenant isolation model and the streaming data flow before writing a component.
Build
We scaffold the component library, wire routes, and integrate third-party services. Every week ends with a working demo deployed to a Vercel preview URL — you can click through the real application, not a Figma mock. Feedback rounds are synchronous, not asynchronous ticket queues.
Launch
Before DNS cutover we run a full Lighthouse audit, verify Core Web Vitals green across all critical routes, complete SEO metadata and JSON-LD schema setup, and run smoke tests on auth, payments, and any third-party integrations. Lighthouse 95+ is a launch gate, not a post-launch aspiration.
Maintain
Post-launch we offer a monthly retainer covering content updates, dependency upgrades, security patches, performance regression monitoring, and scoped feature work. Most clients keep the retainer running because the team already knows the codebase and time-to-ship for incremental features is a fraction of a cold-start agency.
