Every project with us starts like this: you write to us with what you need and we reply with a clear plan, without jargon. Try one of these examples.

  4. 04 / 05· SEO & GEO

    Ranking on Google and in AI answers

    Get found when people search for what you offer, both on Google and when they ask ChatGPT, Gemini or Perplexity for a business like yours.

    • Technical audit of your site, speed, indexing and the errors holding your ranking back
    • Keywords and content built around what your customer is looking for, not filler
    • Structured data and copy prepared so AI assistants cite you (GEO)
    • Monthly follow-up with clear reports on rankings, visits and enquiries

    A good fit if you have a website but hardly any traffic reaches it, or you want to show up when someone asks an AI for a service like yours.

    Improve my rankingMore about this service
    Technologies:Search ConsoleCore Web VitalsSchema.orgIA · LLMs

    GEO (ranking in AI assistants) is new and nobody can guarantee appearances in their answers. We work on what your site does control, clear content, structured data and authority, and show you the results with real data.

  5. 05 / 05· Security audit

    Security audits for websites and apps

    We review your website, your app and its backend the way an attacker would, before a real one does, and give you a clear report of what to fix and in what order.

    • Website and server: the most common vulnerabilities (OWASP Top 10) and anything exposed by mistake
    • API and backend: every user only sees and touches their own data
    • Mobile app, database and cloud: keys, Supabase or Firebase rules and files
    • AI features: prompt injection, data leaks and what the AI does on its own

    A good fit if you're about to launch an app or SaaS with users and data, you built it with help from AI, or a client is asking you for security guarantees.

How we work

From the first call to launch.

A simple, transparent process: you know what is happening at every stage and what it costs from day one.

  1. 01

    Video call

    Intro call

    You tell us what you need, who it is for and what problem you want to solve. No commitment, no jargon.

  2. 02

    In writing

    Proposal and fixed quote

    We send you the scope, timeline and a fixed price in writing. You know what you'll get and what it costs before we start.

  3. 03

    Every week

    Build with weekly deliveries

    Every week you see real progress in a staging environment and give feedback. No disappearing for three months.

  4. 04

    And after

    Launch and support

    We ship it, make sure everything works and show you how to manage it. After that we stay available for improvements and maintenance.

About us

Hi, we're Vigía Studio.

A web and mobile development studio for companies and businesses. We design, build and maintain custom websites, apps and software with one criterion: they have to actually work and help you sell more, get organised or serve your customers better.

For us, design and programming are not two trades. They are the same one. What we deliver has to look good, load fast, be secure and be maintainable without depending on anyone.

Mission

For every company, whatever its size, to have the website, app or software it needs: without jargon, without surprises in the price and without depending on anyone to maintain it.

Vision

To be the studio businesses come back to when they want to take the next step: the website that grows, the app that comes next, the integration that saves work. Technology you notice in the business, not just on the invoice.

Our principles

  1. 01

    Clarity

    A written proposal, a fixed scope and price, and language you understand. No small print and no surprises halfway through.

  2. 02

    No middlemen

    You talk directly to the people who design and build your project. Less noise, fewer misunderstandings, faster decisions.

  3. 03

    Built to last

    Fast, secure and easy to maintain. We review it through an attacker’s eyes and leave it ready to grow with you.

  4. 04

    Truly yours

    When we finish, you get the code, the access and the documentation. You don’t depend on us, although we love staying by your side.

Testimonials

What our clients say.

  • Photo of Raúl Clyde

    Raúl Clyde

    Artista · Cuatronueve49

    My old site was slow and did not represent me. Now the store is fast, has the brand's style and my team runs it on their own.

  • Logo of ALA Interpreting

    Ana Liñana

    ALA Interpreting

    We offer many different services and I was worried the website would be a mess. It turned out tidy and professional, and every service is easy to find.

  • Logo of Black Sheep Clothing

    Alejandro Campos

    Black Sheep Clothing

    We wanted our own store that looked like the brand, not just another template. The site has our style, the photos shine and buying is easy.

  • Logo of Karting League

    Karting League

    We needed one place to keep races, standings and teams up to date. Now we update it ourselves after every race day and the drivers check everything from their phones.

  • Logo of MCConfección

    Mari Carmen Roig

    MCConfección

    The website shows my pieces as they are, made by hand, and makes it clear that I take custom orders. Best of all, I upload the new photos myself.

Before we start

Frequently asked questions.

Can't find yours? Write to us and we'll answer personally.

Ask us your question
How long does a project take?

It depends on the scope. As a guide, a landing page can be ready in 2 to 3 weeks, a corporate website or online store in 4 to 8, and an app or custom software usually takes 2 to 4 months. The proposal includes a concrete timeline with weekly deliveries.

How much does it cost? How do you quote?

Every project is different, so we don't work with catalogue prices. After the first call we send you a proposal with a fixed scope and price: you know what you'll pay before we start, with no surprises. If you have a maximum budget, tell us and we'll suggest what can be done with it.

What happens after launch?

You can take a monthly maintenance plan (updates, backups, small changes and support) or ask us for improvements whenever you need them. Either way, you're never left alone with a freshly launched website.

Who owns the code?

You do. When we finish we hand over the source code, access credentials and the documentation you need. You don't depend on us to keep going, although we'll be happy to keep helping.

Do you work remotely?

Yes. We work remotely with companies and businesses across Spain and abroad, in Spanish or English. We coordinate over video calls, email and whichever tool suits you best.

What is GEO and how is it different from SEO?

SEO works to get your website showing up on Google when someone searches for what you offer. GEO (generative engine optimisation) does the same for AI assistants like ChatGPT, Gemini or Perplexity, which more and more people use to ask for recommendations. Many of the foundations are shared: clear content, structured data and a technically healthy site. Nobody can guarantee appearances in AI answers, so we work on what your site does control and measure it with real data.

What does the security audit include?

We review your website, mobile app or SaaS the way an attacker would: the most common vulnerabilities (OWASP Top 10), the API and backend (every user only sees their own data), what the app stores on the phone, the cloud database and, if there is one, the AI side. You get a report with findings ranked by severity, how to fix each one and a re-test once they're fixed. We only audit with the owner's signed permission. It is not a certification or a compliance audit: if your case needs one, we'll tell you.

Do you use WordPress or only custom development?

Both. We pick the technology for your case: WordPress, WooCommerce or Shopify when you want to manage your content or store yourself easily, and custom development (Next.js, Astro, React Native or Flutter) when you need more performance or specific features.
