What a web development project includes

Six phases, from defining the scope to the security review before production. None of them is skipped, because each one is what stops the project from spiralling in the next.

Architecture and scope

We define which pages, which logic and which integrations the project needs before writing any code. A clear scope is what makes a fixed quote possible.

UX/UI design

Navigation structure, wireframes and screen design. Design aimed at getting the visitor to do what you want them to do, not at winning awards.

Frontend and backend

Full development: interface, business logic, database, admin panel and APIs to connect with what you already use.

Content and technical SEO

URL structure, metadata, sitemap, structured data, speed and correct rendering. A website that is invisible on Google is a website that does not exist.

Integrations

Payment gateways, CRM, ERP, email, analytics, e-invoicing or any system you need to talk to. With credentials stored properly, not in a text file on the server.

Security review and hardening

What sets us apart: we review forms, authentication, access control, file uploads, headers and dependencies using the same methodology as a penetration test, before launch.

Who this service is for

  • Companies that need to replace an outdated website and want to close security holes they have been dragging around for years.
  • Businesses that have received an agency quote and want something more than a WordPress theme with unpatched plugins.
  • Teams with a SaaS product that need a marketing site or a client portal integrated with their platform.
  • Startups that are already selling and need a corporate website that survives an investment round and a technical due diligence.

If you need a single conversion page instead of a full website, that is landing page development. And if you also need a mobile application, it is under mobile app development.

Frequently asked questions about web development

How much does a company website cost?
An informative corporate website of 5 to 10 pages starts at €4,500. A portal with a private area, user roles and integrations with internal systems runs between €12,000 and €30,000 depending on scope. What drives the cost is not the number of pages, it is the logic behind them: authentication, an admin panel, ERP or CRM integrations, and sensitive data that forces a security review. In the discovery call we agree a closed scope and you get a quote within 24 hours.
What technologies do you use?
Next.js and React on the frontend, Node.js or Python on the backend, PostgreSQL or MySQL as the database. For corporate content without complex logic we use whichever stack fits best with whoever will maintain it afterwards, because delivering code the client cannot maintain is not delivering anything. We deploy on Vercel, AWS or Azure, with domain, HTTPS, email and analytics configured.
How is a website built by MagnoSec different from one built by a normal agency?
We review it the way an attacker would before handing it over. An agency ships the site when it works. We ship it when it works and has survived a security review: forms, authentication, access control, headers, dependencies and data handling. Most corporate websites we audit have some problem in the contact form or the admin panel. We would rather find it ourselves before launch.
How long does a web development project take?
A corporate website of 5 to 10 pages takes 3 to 5 weeks. A portal with a private area takes 6 to 12 weeks depending on the number of integrations. The security review adds less than a week if it is done during development, and up to three if it is left to the end and parts have to be rebuilt.
Do we get the code and the whole project?
Yes. The repository, the database, the infrastructure accounts and the documentation are yours when the project ends. If you have an in-house team we run a technical handover session. If you would rather we keep maintaining it, we offer monthly support, but it is not a condition of the project.
Do you do maintenance or only development?
Both. You can hire the development and take the project with you, or add monthly support covering dependency updates, backups, monitoring and development hours for changes. Dependency updates matter more than they seem: most incidents on corporate websites start with a library that had a public CVE nobody patched.

What would your website cost?
