Web & Application Development
High-performance websites and full-stack web apps built on modern frameworks that ship the least JavaScript possible.
Web & Application Development at Prixelo covers everything from a marketing site to a full internal platform with dashboards and real-time data. We build marketing and brand sites in Astro or Next.js, single-page web applications and admin panels in React and TypeScript, installable progressive web apps that work offline, and content platforms on Sanity, Contentful, or Payload for teams that need to publish without touching code. When an existing site is slow, hard to maintain, or failing Core Web Vitals, we assess whether to modernize it or rebuild it outright.
This service fits two kinds of teams: companies that need a site or app built from scratch, and companies with something already live that's costing them conversions or engineering time. A SaaS company needing a customer portal, a marketing team needing a site that ranks and loads fast, an agency handing off a CMS its editors can actually run — all of that is one engagement, scoped to what's actually being built.
The approach stays consistent regardless of project size: pick the lightest framework that does the job, keep JavaScript off the critical path, and structure content and data cleanly so routine changes don't require an engineer every time. Pricing reflects that range directly — marketing sites start at $4,000, content platforms at $12,000, and full web applications at $30,000+, scoped to the complexity of what's being built rather than a flat rate.
Our process
Stack & Architecture
Assess whether the build is a marketing site, application, PWA, or CMS platform, then choose between Astro, Next.js, and React and define the TypeScript data model up front.
Design & Prototyping
Build interactive screens and component systems in TailwindCSS covering the key flows — dashboards, portals, content entry — before a line of production code ships.
Build & Content Integration
Develop the frontend in React, Next.js, or Astro, wire up Sanity, Contentful, or Payload schemas for editors, and implement real-time data, offline caching, or service workers as needed.
QA & Performance Launch
Audit Core Web Vitals, accessibility, and cross-device behavior, then deploy and monitor — the same pass we run when rescuing an existing site's speed and rankings.
