Docastix is a small, senior studio that designs and builds mobile apps, AI automations and SaaS platforms. We work the way we’d want an engineering partner to work with us: direct, transparent, and accountable for the outcome.
We don’t sell development hours. We build product: software meant to earn more, run better, and free you from depending on anyone.
You talk to the people writing the code. We scope the work up front, agree a fixed price, and ship weekly demos you can use on your own device — so you always know exactly where the project stands.
Based in Galicia, Spain, we partner with companies across Europe and on international projects. Same time zone as most of our clients, no offshore hand-offs, no surprises.
No middlemen
Your project is built directly by the founder — a senior engineer with 15+ years. No juniors, no outsourcing.
Code is 100% yours
All source code is yours from day one. No hidden dependencies, no lock-in.
Modern technology
Flutter, Next.js, Supabase, n8n. A current, powerful and maintainable stack. Nothing legacy or obsolete.
Honest quotes
We tell you what it really costs. If your idea needs adjusting to be viable, you’ll know before we start.
Measurable results
Every project has clear KPIs. We focus on real impact for your business, not lines of code.
European quality, no offshore
A team in Spain, your time zone, direct contact. We work with clients across Europe and on international projects — no intermediaries, no surprises.

“I started Docastix to build software the way it should be built — by senior engineers who care about the business behind the code, not just the code.”
Fifteen years shipping mobile apps, web platforms and AI systems for startups and established companies. The studio stays small on purpose: it’s how we keep quality high, communication direct, and every delivery on time.
