Web Development in Sri Lanka.
Web development in Sri Lanka — Next.js, WordPress, headless and bespoke builds. Fast, indexable, accessible sites engineered for SEO and conversion. From Uniix Studio.
Web development that ships, performs and ranks
Most Sri Lankan websites in 2026 ship slow. The Lighthouse scores are unprintable. Images aren't optimised. JavaScript bundles are bloated. Core Web Vitals fail. Schema is missing. The result: even a beautiful site loses to a faster, less-polished one in Google ranking and customer trust.
We engineer websites that ship fast, run fast, and rank. Next.js with App Router for modern product and marketing surfaces. WordPress when content teams demand it. Headless commerce when scale and customisation justify it. Each engagement starts with a stack decision based on the work, not on what we like to write.
What we build
- High-performance marketing sites — Next.js + headless CMS (Sanity, Payload, Contentful) or WordPress
- SaaS and platform products — full custom Next.js with auth, billing, dashboards, admin
- Ecommerce stores — see dedicated ecommerce service
- Marketplaces — multi-sided platforms with role-based UX
- Internal tools and admin dashboards — operational software built with serious component libraries
- Integration-heavy builds — CRMs, ERPs, payment providers, ad platforms, BI tools
What strong web development looks like in 2026
Three engineering principles we don't compromise on:
- Performance budget enforced. LCP < 2.5s, CLS < 0.1, INP < 200ms on real Sri Lankan mobile devices. Measured continuously, not just at launch.
- SEO foundation engineered in. Schema, sitemap, canonical handling, internal linking architecture — built at the framework level, not bolted on.
- Accessibility default. WCAG 2.1 AA is the baseline. Semantic HTML, keyboard navigation, focus management, screen-reader testing.
The technical SEO foundation matters because it's the layer the SEO services team builds content authority on top of. A site with broken schema and bad Core Web Vitals can't rank no matter how strong the content.
How web development fits with adjacent work
- Web design produces the Figma source the development team builds from
- UI/UX design handles deep product flows for complex platforms
- Ecommerce, WordPress and mobile apps are specialised builds inside the broader technology pillar
- SEO, content marketing and analytics are the growth disciplines built on top of the engineering foundation

What separates our engineering
- Senior engineers on every build. No junior-led teams with a senior reviewer.
- Component-first, design-system aligned. We build against the Figma source as a system, not screen-by-screen.
- Type-safe everything. TypeScript end-to-end, validated schemas, no
anyin production code. - Performance instrumented from day one. Vercel Analytics, Speed Insights, real-user monitoring — not just Lighthouse at launch.
- Documented architecture. Every codebase ships with an
ARCHITECTURE.mdand onboarding docs — your future engineers can take over without us.
If your current site is slow, doesn't rank, or breaks every time you push a marketing update, it's an engineering problem dressed up as a design problem. We'd start with an audit, not a rebuild pitch — sometimes the fix is a few weeks of work, not a year-long re-engagement.
How an engagement actually runs.
- Step 01 · Week 1
Technical scoping
Stack selection, hosting, CMS choice, integrations, performance budget and SEO requirements. Engineered before code is written.
- Step 02 · Week 1-2
Setup + foundation
Repository, environments, CI/CD, design system port to code, base components. The infrastructure most projects skip.
- Step 03 · Week 2-6
Build
Component-first build against the Figma source. Continuous deployment, frequent stakeholder previews.
- Step 04 · Week 4-7
Integrations + content
CMS data model, third-party services, analytics, form handlers, payment gateways. All testable in staging.
- Step 05 · Week 7-8
Launch + handoff
Performance pass, Lighthouse audit, accessibility audit, schema, sitemap, robots, DNS cutover and post-launch monitoring.
Concrete deliverables, not promises.
Production-ready codebase
Next.js (App Router), WordPress, or headless commerce — clean, documented, deployable.
CMS data model
Content modelled for the editors who'll use it. Field structures, validation, preview environments.
Performance budget hit
Core Web Vitals green — LCP < 2.5s, CLS < 0.1, INP < 200ms on real devices.
SEO foundation
Schema markup (Organization, BreadcrumbList, Article, Product etc.), sitemap, robots, canonical handling.
Accessibility pass
WCAG 2.1 AA compliance — semantic HTML, contrast, keyboard nav, focus management, ARIA where needed.
Analytics + tracking
GA4, server-side tracking, Meta Pixel + Conversions API, custom event tracking — all wired correctly.
CI/CD + hosting
Vercel, AWS or self-hosted — automated previews, production deployments, rollbacks, monitoring.
Post-launch maintenance
Optional ongoing support — security updates, performance monitoring, feature work.

Frequently asked
questions.
Quick answers to what clients ask most before starting a web development engagement.
How much does web development cost in Sri Lanka in 2026?
A marketing site build on Next.js or WordPress starts at LKR 400,000. A custom SaaS or platform build with auth, dashboards and integrations starts at LKR 1,500,000. Ongoing engineering retainers for product teams start at LKR 280,000/month for embedded engineering capacity.
Which stack do you recommend — Next.js or WordPress?
Next.js for high-performance marketing sites, SaaS, product surfaces, and brands that prioritise page speed and modern DX. WordPress for content-heavy publishers, businesses with non-technical content teams, or sites needing the plugin ecosystem. Both are first-class — the right choice depends on the team and the work, not theology.
Do you build on Webflow, Wix or Squarespace?
Rarely. We work in code for projects that need to scale, integrate with serious infrastructure, or rank competitively in SEO. For very small static sites, no-code platforms can be right — we'll tell you when that applies and recommend a path.
How long does web development take?
Marketing sites: 4-8 weeks after design is approved. SaaS / platform builds: 12-26 weeks depending on scope. Ecommerce stores: 6-10 weeks. We can ship faster with extended engagement hours; we don't ship faster by skipping fundamentals.
Do you handle hosting and maintenance?
Yes. We deploy to Vercel by default for Next.js builds and to managed WordPress hosts (Kinsta, WP Engine, or local equivalents) for WordPress. Ongoing maintenance is offered as optional retainer — most clients take it for 6-12 months post-launch.
Do you support continuous deployment?
Yes — every build ships with CI/CD from day one. Preview deployments for every pull request, automated production deployments on merge, instant rollback, monitoring and alerting. This is non-negotiable for serious work.
