React and Next.js development for websites and products that have to be fast.

Zolarys builds websites, web applications and SaaS products in React and Next.js with TypeScript. Next.js gives marketing sites server-rendered pages that load fast and index properly, and gives applications the structure to grow without a rewrite. We design the interface, build the frontend and backend, connect your data and deploy — on Vercel, AWS or the hosting your team already uses.

Is this the right fit?

A good fit for companies replacing a slow or template-bound website, startups building a SaaS product or customer portal, and teams who want a React codebase their own engineers can own after launch.

What we can deliver

Fast, indexable marketing sites

Statically generated or server-rendered pages, optimised images and fonts, structured data and clean URLs. A CMS — headless or otherwise — so your team edits content without a developer, and a build pipeline that publishes changes in minutes.

Web applications and SaaS products

Authentication, roles and permissions, dashboards, billing and integrations built on a typed API layer. Server components, route handlers and edge functions are used where they genuinely help, not for their own sake.

Design systems and component libraries

Reusable, accessible React components with Tailwind or your existing styling, documented and tested so new screens are assembled rather than rebuilt.

Performance and deployment

Core Web Vitals budgets, bundle analysis, caching and CDN configuration, preview deployments for every change and monitoring after launch. We hand over a repository with CI, environments and documentation.

AI Education Platform

Thaxas

Thaxas is Zolarys' flagship in-house AI education platform built to help students study smarter from their own course material instead of generic internet knowledge. Students can upload lecture slides, PDFs, notes and recordings into dedicated workspaces where AI instantly generates flashcards, quizzes, study guides, summaries, lecture notes and grounded answers with citations from their own content. Unlike traditional AI assistants, every response is tied directly to the student's uploaded material, creating a trustworthy study companion for exams, assignments and long-term retention.

Decisions to make before the build

Next.js or plain React?

Next.js is the right default for anything with public pages that must be found in search or that benefits from server rendering. A pure React single-page app can still make sense for an internal tool or a product behind a login. We choose per project and explain why.

Which backend and database?

Node with Postgres covers most products; Firebase or Supabase accelerates an early-stage product; an existing API can be integrated as-is. The choice follows your data, your team and your hosting costs.

Rebuild or migrate incrementally?

An existing site or app can often be moved to Next.js page by page, preserving URLs and search rankings along the way. We review what you have before recommending a full rebuild.

How the project moves forward

  1. 01Agree on goals, pages or features, data sources and hosting.
  2. 02Design the interface and the component system.
  3. 03Build in reviewable milestones with preview deployments for every change.
  4. 04Launch, measure performance and hand over the codebase and pipeline.

Budget and scope

Marketing websites in Next.js fall within our published website packages, from $499 (₹20,000 in India) to $2,999 and above for larger builds. Applications and SaaS products are quoted per project after scoping, with payments split across milestones.

Questions about react & next.js development

Why build a website in Next.js instead of WordPress?

Next.js sites are typically much faster, more secure and easier to shape around your content and design, and they rank well because pages are served as complete HTML. WordPress still fits some teams, and we will say so if it fits yours — we are not tied to one tool.

Can you take over an existing React codebase?

Yes, after a review. We assess structure, dependencies and test coverage, then propose whether to extend, refactor or rebuild, with the reasoning written down.

Do you use TypeScript?

Yes, throughout. Typed code catches a whole class of bugs before they reach users and makes the codebase far easier for your own engineers to pick up later.
