Web Applications
SaaS dashboards, internal tools, and customer portals — shipped on Next.js + Node.
Where teams get stuck
Web apps rot quickly. Last year's stack is this year's tech debt. Teams either ship a sluggish single-page app, or they shovel features into a no-code tool until the maintenance cost outruns the savings.
What we build
Production-grade web applications on Next.js, TypeScript, and Postgres — server-rendered where it matters, hydrated where it doesn't. SaaS dashboards, customer portals, internal tools, and storefronts shipped fast and built to outlive the next framework wave.
How web applications actually works at Codult
A modern web application has to do three things well: load instantly, stay typed end-to-end so refactors don't break production, and ship to users without a deploy ritual that takes half a day. Our stack is built around those three constraints.
We default to Next.js with the App Router, TypeScript everywhere, and Postgres with a typed query layer (Prisma or Drizzle). For real-time and offline scenarios we add WebSockets or local-first sync. For payments it's Stripe; for auth it's Clerk, NextAuth, or your existing SSO. Boring choices, deeply integrated, easy to hand over.
Performance isn't an afterthought. Server components handle data-heavy routes, edge functions handle latency-sensitive ones, and we run Lighthouse and Core Web Vitals on every PR. The result is web apps that score 95+ on performance and accessibility before launch, not as a follow-up sprint.
We ship in 2-week increments to a live staging environment with weekly demos. Authentication, billing, analytics, and observability are wired in from week one. After launch you get docs, tests, runbooks, and a 30-day pair-programming window — and most clients keep us on retainer for feature work.

The stack
Common questions
Why Next.js over a traditional SPA?+
Server components keep payloads small, SEO works without workarounds, and routing is built in. For data-heavy dashboards and content-driven apps, Next.js is faster to ship and faster to load.
Can you migrate from our legacy Rails / Laravel / WordPress app?+
Yes. We've done incremental migrations using a strangler pattern — new features ship on Next.js while legacy routes stay live until they're cut over.
Do you handle DevOps and hosting?+
Default is Vercel for product-led apps and Azure for enterprise. We hand over IaC and CI/CD so your team can run it independently after launch.
What about real-time features (chat, presence, live updates)?+
Pusher, Ably, or self-hosted WebSockets, picked per use case. For local-first or offline scenarios we use Replicache or Yjs.
How long until we see something live?+
A clickable prototype in week 1, an internal beta in week 4, and a production launch in 10–12 weeks for a typical MVP.
