Built from scratch, never from a template

Websites and apps that keep working while you serve customers

We build the site your business actually needs: bookings that come in on their own, payments that record themselves, and an admin panel you run yourself. No platform fees, no plugins that break, and the code stays yours.

What we build

Every project starts from what your business genuinely needs. No recycled templates with your logo dropped on top.

  • Business websites

    The site that represents your business: fast, indexable and editable. Structured so a visitor understands what you do in five seconds and knows how to hire you in ten.

    • Bespoke responsive design
    • Technical SEO from day one
    • GDPR-compliant legal pages
  • Landing pages that convert

    One page with a single job: getting the visitor to do the thing you brought them there for. Measurable, quick to publish and built to support campaigns.

    • Focused on one clear action
    • Loads in under a second
    • Ready to measure results
  • Custom web applications

    For what no plugin solves: real diaries, management panels, user accounts with permissions, calculations specific to your business.

    • Your own admin panel
    • Real roles and permissions
    • Integration with external services
  • Online booking and payments

    An availability calendar you control, with server-side validation that makes double booking impossible, and payment through the channel you already use.

    • Diary you configure yourself
    • No double bookings, guaranteed
    • Exportable payment records
  • Performance and SEO

    We audit and fix what slows your site down: heavy images, third-party scripts, structure Google cannot read. Speed is part of the design.

    • Full technical audit
    • Image and loading optimisation
    • Structured data and sitemap
  • Maintenance and growth

    The project does not end at launch. We stay on to update, fix and add what comes next, with automatic deployment on every change.

    • Automatic deployment from Git
    • Backups and updates
    • Direct support, no ticket queues
Why us

What sets us apart

Four decisions we make on every project that you will notice from day one.

  • The code is yours

    We hand over the full repository. If you want to change supplier tomorrow, you take everything with you. No expiring licences, no site held hostage by a platform.

  • No monthly platform fees

    No subscription site builders, no paying per feature for plugins. We program what is needed, so you pay for hosting and little else.

  • Security by design

    Validation always on the server, hashed passwords, lockout after failed attempts and permissions enforced in the database, not just on screen.

  • You run it

    Every project ships with its own admin panel. Changing opening hours, uploading photos or publishing an article does not mean calling us or paying by the hour.

Work

Real projects, live in production

These are not mockups or concepts: they are businesses running on these systems. Open each case to see the problem, the technical decision and the result.

How we work

From idea to production in four steps

No surprises and no budgets that grow halfway through. You always know where the project stands.

  1. 01

    We talk

    A call or a few messages to understand your business, what is costing you time and what you expect to achieve. Free and with no commitment.

  2. 02

    Fixed proposal

    You get scope, timeline and price in writing. What is included and what is not is clear before we start, not after.

  3. 03

    We build and show

    We work in parts and show you progress on a real link. You give feedback on what you can see, not on a description.

  4. 04

    We launch and train you

    We go live with domain, certificate and backups, and we teach you to run your panel. From then on, we stay available.

FAQ

What people usually ask

How much does a website cost?
Prices are published in the plans section: from €690 plus VAT for a landing page up to €2,890 plus VAT for a site with bookings, accounts and an admin panel. Projects with their own logic start at €5,900 plus VAT and are quoted individually. The price is agreed in writing before we start and does not move.
How and when do I pay?
When you book you pay a 30% deposit plus VAT online, which reserves your slot in the schedule and starts the work. The remaining 70% is invoiced on delivery, once the project is live and working. There are no automatic charges and no lock-in. Payment is processed by Stripe and accepts card, Bizum, Apple Pay and Google Pay.
What is the user account for?
So you can see your project status, keep your invoices to hand and update your billing details without asking us. You can sign in with Google, Facebook, Apple, or a link we email you — no password to remember.
How long does it take?
A landing page is usually live in one or two weeks. A full business site takes three to five. An application with bookings, accounts and an admin panel is built in phases, and the first phase is already useful while we build the next.
Will I be able to update the site myself?
Yes, that is the whole point. Everything that changes often — opening hours, photos, articles, prices, availability — is managed from your admin panel. We train you at handover and leave written documentation.
Do you use WordPress?
Not by default. We build bespoke because it avoids plugin subscriptions, incompatibilities between extensions and the security burden of keeping an entire ecosystem patched. If a content management system genuinely fits your project better, we will say so plainly.
What if I want to change supplier?
You take everything. The code lives in a Git repository that belongs to you, along with the database and the technical documentation. We do not use closed formats and we do not keep parts of your site under our own licence.
Do you work outside Spain?
Yes. We work fully remotely and have already delivered projects for clients in Spain and Argentina. Meetings happen over video call and day-to-day contact over WhatsApp.
Is maintenance included?
Handover includes a warranty period to fix any defect at no cost. After that you can take out ongoing maintenance or simply call us when you need to, with no lock-in.
How do you handle my customers’ data?
With the measures GDPR requires: passwords always hashed, validation on the server, permissions enforced in the database rather than the interface, and privacy and cookie policies included in the delivery.
