Work That Speaks
A selection of websites and apps we've built for clients across Kolkata and beyond.
The Technology Stack Underpinning Each Website We Create
We don't follow every new framework that becomes popular on social media as a web development company in Kolkata. This isn't just a logo wall; it's the stack we really use in production, arranged by purpose, along with the rationale behind each decision.
Everything a visitor sees and engages with is part of the frontend. Because a bloated frontend is the primary cause of slow-loading, low-ranking websites, we keep this layer standards-based and lightweight.
The backend runs the business logic a visitor never sees - form processing, user accounts, and database queries. We choose the language based on the project, not the other way around.
The database stores everything the site needs to remember - products, orders, users, content. Choosing the right one affects how the site performs as your data grows.
Where and how a site is hosted directly affects uptime, load speed, and how well it survives a traffic spike - during a sale, a festival campaign, or a viral moment.
A CMS decides how much control you have over your own site after launch. We pick the platform based on whether you want to edit content yourself and how you plan to sell.
Frameworks give a language structure and built-in tooling, so we spend time on your business logic instead of reinventing routing, authentication, and security from scratch.
DevOps practices are what keep code changes safe, trackable, and reversible - the difference between a controlled update and an accidental site-breaking deploy.
Security is built in from the start, not patched on after launch - this is the same set of practices covered in detail on our Why Choose Us section.
APIs connect your site to the outside services it depends on - payments, maps, shipping, and other third-party tools your business already uses.
AI is added where it genuinely saves you time or converts more visitors - never as a checkbox feature bolted on to look modern.
Web3 and decentralized technologies power trustless smart contracts, tokenized ecosystems, and dApps - built with industry-standard frameworks for maximum security, auditability, and speed.
Carnival Trips – Travel Web Application

The platform is optimized for performance using CDN caching, PWA features for offline capabilities, and Open Graph configurations for social sharing, built on a Next.js/Node.js stack with Tailwind CSS styling.

Website Development Services We Offer in Kolkata
As a website development company in Kolkata working with local and Pan-India businesses since 2010, here is exactly what we build, how each service is for, and how we deliver it - No Hidden charges, No delays on timeline.
Custom Website Development
We code every site from scratch as a dedicated web development company in Kolkata - no recycled themes, no drag-and-drop builders. You get a site structured around how your customers actually search and buy.
- Faster load times and stronger Core Web Vitals than template sites
- No licensing lock-in - you own the code outright
- Built to scale as you add features, without a rebuild
Our process: discovery call → wireframes → design → development → testing → launch. See the full breakdown on our website development process page.
Get a Free Website QuoteE-Commerce Website Development
We've built online Intractive High Converting Stores for sarees, electronics, organic food, and jewellery brands across Kolkata. Custom E-Commerce, Next.Js, Node.Js, React.Js and Shopify cover most needs; if your catalogue or checkout flow doesn't fit either, we build a custom cart.
- Sell 24/7 through a channel you fully control
- Secure payment gateways: Razorpay, PayU, Stripe
- Inventory, coupons, and order management built in
Our process: product & catalogue audit → platform selection → store build → payment/shipping setup → launch. Compare plans on our pricing page.
Start Your Online StoreWordPress Development
Most clients start updating their own WordPress site within a week of handover. We build the backend so it makes sense to someone without a technical background, and we stay reachable if they get stuck.
- Edit pages, blogs, and images without calling a developer
- SEO-friendly structure from the first page you publish
- Wide plugin ecosystem for bookings, forms, and more
Our process: content mapping → theme/plugin setup → custom design → training handover → ongoing maintenance support.
Talk to Us About WordPressResponsive Web Design
Over half of web traffic in India comes from phones. We design mobile-first and test every build on real Android and iOS devices before it's handed over, not just in a browser resizer.
- Consistent experience across phones, tablets, and desktops
- Passes Google's mobile-usability and Core Web Vitals checks
- Lower bounce rates from frustrated mobile visitors
Our process: mobile wireframe first → responsive build → device testing lab → performance check → sign-off.
Request a Mobile AuditReact & Next.js Development
When a standard website isn't enough - dashboards, client portals, or SaaS products - we build with React and Next.js. Fast, scalable, and free of the plugin sprawl that slows WordPress sites down over time.
- Server-side rendering for strong SEO on dynamic apps
- Component-based builds that scale with your product
- API-ready architecture for integrations and dashboards
Our process: tech-stack scoping → API design → sprint-based build → QA → deployment. See our stack in detail on the technologies page.
Discuss Your App IdeaWebsite Maintenance & Support
We stay on after launch. Our maintenance plans cover plugin updates, security checks, backups, and small content edits - one message to us and a broken site gets fixed, usually the same day.
- Reduced downtime and fewer security vulnerabilities
- Regular backups so nothing is ever truly lost
- One point of contact instead of juggling freelancers
Our process: site audit → plan selection → monthly monitoring & updates → priority support on request. Compare plans on our pricing page.
Get a Maintenance PlanWhy We Build Custom, Not from a Template
A lot of agencies in Kolkata quote lower prices by starting from a pre-built theme. That's not automatically wrong - for a very simple brochure site it can work - but here's what it usually costs you later.
Templates ship with code for features you'll never use. That extra weight slows down load time and hurts your Core Web Vitals score, which Google uses as a ranking signal.
Custom code is built around your business logic, so adding a booking system or CRM integration later doesn't mean fighting against theme limitations.
Template sites are recognisable - visitors have seen the same layout on ten other websites. Custom design gives you something that's actually yours.
What a Good Website Actually Does for Your Business
A website isn't a cost centre if it's built right. Here's the business case, in plain terms.
A clear call-to-action on every page turns visitors into enquiries instead of losing them to a competitor's tab.
Clean structure and fast pages mean you show up for the searches your customers are already making.
An e-commerce build turns your website into a sales channel that works outside store hours.
A professional site is often the first thing a new customer checks before calling - it's doing sales work before you even speak.
Why We Pick Each Technology We Use
We don't default to one stack for every project. Here's why each of our core technologies gets used, and when.
Used for dashboards, portals, and any site that needs fast page transitions and strong SEO through server-side rendering.
Our default for CRM, ERP, and custom business logic - mature, secure, and fast to build reliable backends with.
Chosen when a site needs real-time features - live chat, notifications, or API-heavy applications.
Best fit when you need to edit content yourself after launch, without depending on a developer for every change.
Used when a business needs one codebase covering both Android and iOS without duplicating development effort.
Chatbots, recommendation logic, and content tools - added where they genuinely save your team time, not for novelty.
AWS and cloud-based hosting for sites that need to scale with traffic spikes, like festive-season e-commerce.
Used for data-heavy backends, automation scripts, and machine-learning components when a project calls for it.
Methodology, Testing, Security & Performance
This is what happens behind the scenes on every project, regardless of size.
Why Clients in Kolkata Keep Coming Back to Us
Not adjectives - process. Here's exactly how we build, test, and support every site, with the evidence behind each claim.
Every project follows the same coding standard: version control on Git for every build, a peer code review before anything ships, and a shared component library so quality doesn't depend on which developer touched the code.
ISO 9001:2015 certified since 2018Before any site goes live, it runs through a fixed checklist covering forms, links, cross-browser rendering (Chrome, Firefox, Safari, Edge), and real-device testing on Android and iOS phones - not just a browser resizer.
Applied to all 900+ launches since 2010Free SSL, hardening against the OWASP Top 10 risks, a locked-down admin login, and a malware scan before handover are included in every project by default - not sold back to you as an "upgrade" after launch.
Standard on every contract, no extra line itemMaintenance clients get uptime monitoring and a written 4-hour first-response commitment during business hours, logged through a ticketing system - so "we'll get back to you" has an actual number attached to it.
Stated in every maintenance contractFrom a Hostel Room to 900+ Projects
A quick look at how Unika Infocom has grown as a web development company in Kolkata.
Where It All Began
Unika Infocom started in a hostel room with two college friends and two programmers. Our first client was Mr. San Pather and his son, Mr. Tyran Pather, from South Africa. More than 15 years later, we are still connected and growing together.
Expanding Technology
We developed our first Antivirus Software Engine and expanded into Windows Application Development, PC Cleaner & Optimizer, Android App Development, iOS App Development, Custom eCommerce, National and International SEO, SMO and payment gateway integrations.
Becoming Unika Infocom Pvt. Ltd.
Unika Infocom became incorporated as a Private Limited company, marking an important milestone in our growth. With a growing team, we expanded into custom CRM, ERP, manufacturing, inventory, and business management solutions for clients across different industries.
ISO 9001 Certified
We achieved ISO 9001 certification, strengthening our commitment to quality, structured processes, and reliable software development.
Modern Web Development
We added React.js and Next.js to our core technology stack, enabling us to build faster, scalable, and modern web applications.
900+ Projects
Unika Infocom crossed 900+ completed projects, serving clients across Kolkata, India, and 12+ countries worldwide.
Growing Together
Still based in Kolkata, we continue to work closely with our clients, focusing on long-term relationships, innovative technology, and quality solutions.

Words from Clients We’ve Worked With
Real feedback from real clients. Their success is our greatest achievement.
"We'd tried building a website ourselves before and it looked terrible on mobile. Unika came in, sorted the whole thing out, and since launch we get 4–5 enquiries through the site every week. Worth every rupee."
"The store launched 5 weeks before Durga Puja and we actually took online travel bookings that season. I didn't expect it to move that fast. The Application is running perfectly from day one."
"I was hesitant about spending money on a website for a clinic this size. Three months in, a patient told me they chose us over another clinic specifically because our website looked more trustworthy. That surprised me."

Unika Infocom vs an Ordinary Web Agency
A fair, practical comparison - not every agency is bad, but this is where the difference usually shows up.
| What Matters | Unika Infocom | Typical Local Agency |
|---|---|---|
| Custom-coded website | Often template-based | |
| Dedicated project owner | Rotates between staff | |
| Core Web Vitals optimisation | Rarely tested | |
| Fixed quote before work starts | Scope changes mid-project | |
| Post-launch support included | Charged separately, slow response | |
| ISO 9001 certified process | Uncommon | |
| 16+ years operating history | Varies widely |
What Actually Affects Website Cost
Two websites that look similar can cost very differently once you factor in these variables.
A 5-page brochure site costs less than a catalogue site with filters, search, and user accounts.
Fully custom illustration and animation take longer than a clean, standard layout.
Payment gateways, CRMs, and third-party APIs each add development and testing time.
If we need to write or source copy and images, that's added scope compared to content you supply ready-to-use.

Website Maintenance Plans After Launch
A website needs upkeep the same way a shop needs its shutters checked. Here's what our maintenance plans cover.
WordPress core, plugins, and dependencies kept current so known vulnerabilities don't linger.
Regular malware scans and firewall checks, with alerts if anything looks off.
Automated daily or weekly backups stored off-server, so you can always roll back.
Small text, image, and price changes handled without you needing to touch the backend.
Clients on a plan get same-day responses instead of joining a general support queue.
Automated checks flag downtime or slowdowns before your customers notice them.

Our Website Development Process, Step by Step
Fifteen stages, grouped into five phases, followed on every project since 2010 - from a five-page business site to a custom web application. Nothing here is skipped to save time or hit a deadline.
We start with a structured discovery call to understand your business model, target customer, competitors, and what "success" looks like for this project - more leads, more sales, or simply a credible online presence. This stage surfaces the constraints (budget, timeline, existing brand assets) that shape every decision after it.
We study three to five direct competitors, review the search terms your customers actually use, and audit any existing website's analytics for what's already working or losing visitors. For e-commerce and multi-service sites, this includes an early keyword map so the site is planned around real search demand, not guesswork.
Findings from discovery and research get turned into a sitemap, a content plan per page, the tech stack (WordPress, Laravel, or React/Next.js, depending on what the project needs), and a milestone timeline. This is the document you sign off on before any design work begins - so scope stays fixed and timelines stay realistic.
Before a single screen is styled, we map the user flow - how a visitor moves from landing on a page to filling a form, adding to cart, or calling you. We plan information hierarchy, navigation logic, and friction points (long forms, unclear CTAs) so the site is built to convert, not just to look good.
We lay out every page in low-fidelity greyscale - no colour, no branding - so layout and content placement can be agreed on before time is spent on visual design. It's far cheaper to move a section here than to redesign a finished, styled page later, and you review this before we touch a design tool.
Wireframes are turned into full visual designs - your colours, typography, imagery, and brand tone applied across every page. We design in Figma so you can comment directly on specific elements, and every screen is approved by you before development starts, not after.
For projects with custom interactions, multi-step forms, or app-like features, we build a clickable prototype so you can navigate the site as a real visitor would - before any code is written. This catches usability issues that are invisible in static designs, like a confusing checkout step or an unclear menu.
Approved designs are built into clean, semantic code - WordPress, Laravel/PHP, or React/Next.js depending on the approved stack. Every project lives in Git from day one, work is peer-reviewed before merging, and you get a weekly progress update with a staging link so you can see real, working pages, not just a status report.
Every build runs through a fixed 40-point checklist: forms submit correctly, links resolve, layouts hold up across Chrome, Firefox, Safari, and Edge, and pages render correctly on real Android and iOS devices - not just a resized browser window. Bugs found here are logged, fixed, and re-tested before moving forward.
Before launch, we check against the OWASP Top 10 risks - things like SQL injection, cross-site scripting, and insecure form handling - enforce SSL, lock down admin logins, and run a malware scan on the finished build. This is included by default on every project, not sold back to you as an add-on after launch.
Images are compressed and served in modern formats, CSS/JS is minified and lazy-loaded where possible, and caching is configured at the server level. We test against Google PageSpeed Insights and Core Web Vitals, and don't consider a build launch-ready until it consistently scores 90 or above.
Every page ships with proper title tags, meta descriptions, header structure, and schema markup relevant to your business (LocalBusiness, Service, Product, or FAQ schema). We submit the sitemap to Google Search Console and connect analytics before handover, so the site is measurable and indexable from day one - not something bolted on later.
Domain, hosting, SSL certificates, and DNS records are configured end to end. We schedule launches for low-traffic hours where possible and stay on call through go-live, so if anything unexpected turns up - a DNS propagation delay, a third-party integration hiccup - it's handled immediately.
After launch, uptime and error monitoring run continuously in the background. If the site goes down, throws a server error, or an SSL certificate is about to expire, we're alerted automatically - often before you'd notice anything was wrong.
We stay on after handover. Maintenance plans cover plugin and core updates, backups, security patches, and small content edits, with a 4-hour first-response SLA logged through a ticketing system - so a broken form or an outdated price gets fixed the same day, not whenever someone finds time.
