What We Offer
Marketing & Corporate Websites
Conversion-optimized websites using Next.js App Router—fast load times, structured data, Core Web Vitals compliance built in. Not a WordPress site with 40 plugins or a Wix template dressed up as custom development.
SaaS Web Applications
Full-featured platforms with authentication, billing (Razorpay + Stripe), multi-tenancy, real-time capabilities, admin dashboards, and public APIs. Designed to scale from 100 to 100,000 users without a rewrite. See MVP Development for rapid launch approach.
E-commerce Platforms
Custom storefronts or headless Shopify/WooCommerce with Next.js frontend. UPI and Razorpay integration, GST calculation, Indian address validation, Shiprocket and Delhivery logistics integration, WhatsApp order notifications.
SEO-First Development
Schema.org JSON-LD markup, semantic HTML5, dynamic sitemap generation, canonical URL management, hreflang for multilingual sites (Hindi, Tamil, Telugu, Marathi)—in the codebase, not a plugin. Every page targets specific keywords from day one.
Performance Optimization
Audits and fixes for existing sites—image optimization pipelines, code splitting, lazy loading, CDN configuration. Typical outcome: 40-70% improvement in LCP (Largest Contentful Paint), measurable ranking improvements within 90 days.
API & Backend Development
REST and GraphQL APIs, database architecture (PostgreSQL, MySQL, MongoDB, Redis), serverless functions, and third-party integrations. Designed for the query patterns your app actually runs, not just the happy path. See API Development Services.
Process
How We Work
Discovery & Scoping
We review your existing site (if applicable), map user journeys, define scope with a detailed specification document, identify SEO requirements, performance targets (Core Web Vitals), and technical constraints. Output: fixed-price estimate and timeline.
Design & Prototyping
Wireframes in Figma, then visual designs with your brand colors, typography, and UI components. All reviewed and approved before a single line of development code is written. Changes in Figma take an hour. Changes in code take a day.
Development in Sprints
Two-week sprints. Staging deployment at the end of each sprint—you test on a real URL on your actual device, not screenshots. Every sprint ships working, tested software. You attend sprint reviews and provide feedback continuously.
QA, Security & Launch
Cross-browser testing (Chrome, Safari, Firefox, Edge), responsive layout verification on 5+ screen sizes, performance benchmarking against Core Web Vitals, security review (OWASP top 10), accessibility audit (WCAG 2.1 AA), and zero-downtime deployment.
Why Crenosoft
Why Choose Us
SEO Built Into Development
We don't bolt on SEO after launch. Every page has a primary keyword target, semantic HTML, Schema markup, optimized meta tags, and correct heading hierarchy from the first commit. Sites launch with 90+ Lighthouse SEO scores, not 60s that need months of fixes.
Performance That Ranks
Core Web Vitals are a ranking factor. We optimize LCP, FID, and CLS from the start—image formats (WebP, AVIF), lazy loading, code splitting, CDN caching. Typical result: 95+ Lighthouse performance, sub-2s load times, measurable ranking improvements within 60-90 days.
DPDP Act 2023 Compliance
Every web application includes DPDP compliance by default—consent management (cookie banners that actually work), data localization for Indian users, audit logs for data access, and cascading delete workflows. For regulated industries, we handle RBI, ABDM, and SEBI requirements.
Modern, Maintainable Code
TypeScript, ESLint, Prettier, comprehensive test coverage, and CI/CD pipelines. Code reviews on every merge. Your codebase will be maintainable for years, not months. If you hire developers later, they won't curse our names.
Indian Payment Integration
We've integrated Razorpay, Cashfree, PayU, and PhonePe Business for 50+ clients. UPI, cards, netbanking, wallets—all tested on real transactions. Webhook handling, reconciliation, GST-compliant invoices, and refund workflows included.
Post-Launch Support
We don't disappear after launch. Monthly retainers (₹1-4 lakhs/month) include security updates, dependency upgrades, performance monitoring, Google Search Console reviews, and a fixed number of hours for bug fixes and small features.
Frequently Asked Questions
Why Next.js over WordPress or Webflow?
WordPress and Webflow are good tools for certain use cases—blogs, simple corporate sites. But for anything that needs custom functionality, high performance, or is likely to evolve significantly, Next.js gives you a codebase you actually own and control. No plugin compatibility issues, no security vulnerabilities from unmaintained extensions, and no performance ceiling imposed by a platform. You can hire any React developer to maintain it—you're not locked into a Webflow expert. Full technical breakdown: Next.js SEO in 2025.
How much does web development cost in India?
Indicative ranges: Marketing website (5-15 pages) ₹1.5-5 lakhs, corporate website with CMS ₹3-8 lakhs, SaaS MVP (core features) ₹8-20 lakhs, full SaaS platform ₹20-50 lakhs, custom e-commerce ₹10-30 lakhs, performance optimization audit and fixes ₹1-4 lakhs. All prices exclude GST. We give detailed estimates after reviewing your specific requirements—not ballpark figures from a 20-minute call. Factors: number of pages, custom features, integrations, SEO complexity, and timeline.
Do you build multilingual websites?
Yes. We've built sites in Hindi, Tamil, Telugu, Marathi, Bengali, Gujarati, and other regional languages with proper i18n support (next-intl or react-i18next), hreflang configuration for regional SEO, correct text rendering for Devanagari and other scripts, and culturally appropriate design adaptations. Common for e-commerce sites targeting tier 2/3 cities and government/public sector projects.
Can you take over a half-built or broken website project?
Yes, but we do a code review first (₹15,000-30,000 for 1-2 day audit). We need to understand the architecture, identify technical debt, estimate what getting to a maintainable state would require, and assess whether continuing or rebuilding is more cost-effective. We give you an honest assessment—including if we think a rebuild is cleaner than patching. We've rescued 20+ projects from other agencies, offshore teams, or abandoned freelancers.
How do you handle post-launch maintenance and updates?
We offer monthly retainers (₹1-4 lakhs/month depending on site complexity and traffic): security updates, dependency upgrades, performance monitoring (Core Web Vitals, uptime), Google Search Console reviews, bug fixes, and small feature additions (10-20 hours/month). We don't disappear after launch. Clients typically stay with us for 12-24 months, then either take maintenance internal or continue on a reduced retainer.
Do you integrate with Indian payment gateways?
Yes—Razorpay, Cashfree, PayU, and PhonePe Business for UPI, netbanking, wallets, and card payments. We handle the full integration: payment flow UI, webhook handling for payment status, reconciliation, GST-compliant invoice generation, and refund workflows. We've processed ₹100+ crores in payments through integrations we've built. All tested on real transactions in sandbox and production.
What's your approach to SEO for web development?
SEO is built into development, not added later. Every page has: primary keyword in H1 and title tag, semantic HTML (header, nav, main, article, section), Schema.org JSON-LD markup (Organization, WebPage, BreadcrumbList, Product for e-commerce), optimized meta descriptions (140-160 chars), canonical URLs, sitemap.xml generation, robots.txt configuration, and structured internal linking. Sites launch with 90+ Lighthouse SEO scores. Post-launch, we track Google Search Console for indexing and ranking. See blog post: Next.js SEO Guide 2025.
Can you migrate our existing site to Next.js without losing SEO rankings?
Yes—we've done 30+ migrations from WordPress, Wix, Shopify, and custom PHP/Ruby stacks to Next.js without ranking drops. Process: audit current site for all indexed URLs, map old URLs to new URL structure, implement 301 redirects for every changed URL, preserve all Schema markup, maintain or improve Core Web Vitals scores, submit new sitemap to Google Search Console, and monitor rankings weekly for 3 months. Most sites see ranking improvements within 60-90 days due to better performance.
Do you provide hosting or just the codebase?
Both options. We can deploy to Vercel (₹0-5,000/month for most sites, auto-scaling), AWS (EC2 + RDS + S3 + CloudFront, ₹5,000-30,000/month), or your own infrastructure. We provide full DevOps setup: CI/CD pipelines (GitHub Actions), staging + production environments, SSL certificates, DNS configuration, database backups, and monitoring (Sentry for errors, Vercel Analytics or Google Analytics for traffic). Or we hand over the codebase and documentation for your team to deploy.
What happens if we need changes after the project is delivered?
Small bug fixes (within 30 days of launch) are covered under warranty—no charge. New features, design changes, or functionality additions are quoted separately. We typically bill ₹3,000-8,000/hour for post-launch work depending on complexity. Most clients opt for a monthly retainer (₹1-4 lakhs/month) which includes 10-20 hours of development time for ongoing improvements. Change requests go through a formal process: scope definition, estimate, approval, then implementation.
