Custom web app development, built to perform

The cost of web app development depends on scope, feature complexity, the number of integrations, and the support you need after launch. A focused marketing site costs much less than a complex SaaS product or a multi-tenant web application. Most of our projects run on fixed-price terms. It starts with a free 30-minute call to understand your goals. After a short discovery phase, we send a detailed proposal with clear milestones and a fixed price, not a time-and-materials estimate that keeps growing mid-project. You know what you are paying for, and when each part will be delivered, before any work begins.

A focused marketing site usually takes 8 to 12 weeks from kickoff to launch. A full web application or SaaS product is typically 16 to 24 weeks. The biggest factors are scope, the number of integrations, and how quickly feedback and content come back from your side. We front-load architecture and design in the first two weeks, so the engineering sprints that follow stay on schedule. By the end of discovery, you have a milestone plan with fixed dates, not a vague range. You also get access to a staging environment from day one, so you can see progress in weekly demos instead of waiting for a big reveal at the end.

WordPress gives you a starting point. Custom web application development gives you a platform built around your users and your business logic. Ready-made tools start to hit their limits when you need complex workflows, deep integrations with other systems, or performance at scale. That said, we build on WordPress a lot, and headless WordPress with a custom front end is often the right call when your editorial team needs to publish quickly. The right choice depends on your product, your team, and your plans for the next few years, not on a fixed preference. We tell you honestly which option fits.

Both. Some clients hand the whole project to us: product strategy, UI/UX design, engineering, QA, and launch. Others have in-house designers or back-end developers and need us to cover specific layers, such as the front end or a new module. We shape the engagement around what you actually need, not a fixed package. During discovery, we agree on the collaboration model, who owns which decisions, and clear handoff points, so nothing falls between teams. If you need extra engineers inside your own team for a longer period, our Dedicated Teams service (staff augmentation) is built for exactly that.

Launch is not the finish line. The first 30 days after launch include hypercare: a named developer on call for urgent fixes, Core Web Vitals tracking, and real-user monitoring, so problems are caught before your users notice them. After that, most web platform clients move to a monthly retainer. It covers security patches, CMS and framework updates, performance monitoring, and development hours for new features. We also hand over full documentation and train your team, so you are never locked in. This approach is a big part of why we keep a 98% client retention rate after launch.

Our core stack for web app development is React, Next.js, Laravel, Node.js, and WordPress, with PostgreSQL, Redis, and AWS or Vercel for hosting and infrastructure. The framework follows the project. We use Next.js for content-heavy sites that need strong SEO and speed, Laravel for complex, data-driven applications, and headless WordPress when editorial teams want a familiar interface. We choose technology based on long-term maintainability and your team's ability to own the code after handover, not on whatever framework is popular this quarter. If you already have a stack, we work with it, and we explain any change we recommend before making it.

Creiden has built for the web since 2011, with 15+ years of experience, 400+ projects, and clients in 15+ countries. We work with founders, product teams, and established businesses that share one need: a platform that actually works in the real world. Every project starts with UI/UX designed from scratch, so your brand shows up the way it should. Our senior team makes the architecture decisions and plans for maintainability, security, and handover from day one. We have delivered 350+ web platforms across 12 industries, and we keep a 98% client retention rate after launch because we stay involved long after the first release.
