Web Platform & Web Application DevelopmentWeb Platforms & Applications
Web applications built around real workflows, not generic admin panels.
For products and internal tools that need more than a marketing site — we build web applications, client portals, dashboards, and SaaS frontends on React, Next.js, and Laravel.
(01) The short answer
What is web platforms & applications?
Web platform development covers the build of application-grade web software: multi-step flows, authenticated user areas, data-heavy dashboards, client portals, and SaaS frontends. Cortexley builds these on React and Next.js on the front end, paired with Laravel or Node.js back-ends when custom business logic, authentication, and data persistence are part of the scope.
(02) Cost & timeline
How much does web platforms & applications cost?
A web application or client portal typically costs £5,000–£18,000 and takes 8–16 weeks, driven by the number of user flows and integrations.

How Much Does a Website Cost in 2026? A Real Breakdown by Project Type
The honest answer: $500 to $150,000+ depending on what you're actually building. Here's a breakdown by project type — with the real variables that move the number.

Before you ask.
A website primarily presents information. A web application processes user input, stores data, enforces business logic, and gives different users different views based on their role or state. The line is blurry — a site with a client login area, a configurable quote tool, or a real-time inventory view is already a web application, even if the rest of it looks like a marketing site.
A focused single-workflow web application with authentication and a back-end API: £5,000–£12,000. A multi-feature platform with complex permissions, reporting, and third-party integrations: £12,000–£18,000, with complex multi-tenant platforms above that. The cost is driven by the number of distinct user flows, the complexity of the data model, and the integration count. We scope every project before quoting.
Yes. We've built multi-tenant systems and internal platforms from the ground up — covering architecture design, front-end build, back-end API, authentication, and deployment. We scope in phases so the first usable version ships faster than a full build, and we structure the architecture to support the features on the roadmap without over-engineering for ones that may never arrive.
We can set up and manage cloud infrastructure (AWS, DigitalOcean, Vercel, Railway) or work within your existing environment. We document the deployment process fully as part of handover so your team can manage it independently if preferred.
