Custom web application development

Founders, product owners, and operations teams who need a tailored web product: a customer self-service portal, an internal admin tool, a subscription SaaS, or a data-driven dashboard. Typical clients are UK businesses ready to move beyond spreadsheets and off-the-shelf tools.

• Customer and partner portals with authentication and role-based access
• Admin dashboards and operator workflows
• API-backed web products and integrations with third-party services
• Marketing sites with embedded product functionality where needed
• Next.js applications with server-side rendering and structured data layers

Describe your web app idea on the Build Anything homepage. Guided questions capture users, core flows, integrations, and constraints. You receive an initial brief with suggested features and indicative ranges. After you submit, Zapa reviews the brief and follows up with clarification or a discovery conversation before confirming final scope.

• Zapa Build Anything: live intake and brief generation product built with Next.js
• Private client web application: authenticated product delivered under confidentiality
• Customer and admin portal: dual-portal build separating self-service from internal operations

Manchester gives us strong access to UK talent and clients while we serve businesses nationwide. We use the same stack we ship on our own products, so architectural decisions are grounded in real delivery experience rather than theory.

We start with agreed scope and milestones, then move through design alignment, iterative build, testing, and handover. For larger products we can phase delivery so you reach a usable first release without committing to every future feature upfront.

Next.js and TypeScript are our default for new web products, chosen for performance, maintainability, and a strong ecosystem. We integrate with common auth providers, payment platforms, CRMs, and custom APIs as the project requires.
