Web apps & custom software

Software that fits your process. Not your process bent to the software.

When Excel, e-mail and three tools no longer suffice, we build the tool that is missing: a customer portal, a booking system, an order management. Start small, put it to work, then extend.

When this is the right fit

“A process eats time and no software fits.”

We look at the process, build the smallest part that helps right away, and extend step by step.

“Customers should book online, with payment.”

We have built booking systems with availability, payment and administration for boat tours, jet-ski rental and holiday villages.

“Our customers keep asking for status.”

A customer portal shows orders, documents and invoices, with login and roles. Your team saves the follow-up calls.

What you get

Proven parts, assembled for you

React, Node.js, PostgreSQL or Supabase, our open-source backend AstroBaaS: technology we run ourselves every day.

Login, roles, privacy

Who may see what is settled from the start. Data stays in the EU, access is logged.

Works on phone and desktop

As a web app in the browser, installable like an app on request, without an app store.

The code is yours

With documentation and access to the repository. You can carry on with another developer at any time.

Connected to what you already use

Lexware, Stripe, Google Calendar, your shop or your inventory system: data flows instead of being retyped.

Operation after launch

We take care of hosting, monitoring and updates from 49 € a month. Extensions come as fixed-price quotes.

How a project runs

You do not have to trust us with a big project right away. Most clients start with one small, clear job.

    Conversation

    30 minutes by phone or video. We clarify what you need, what already exists and what is really missing. Free and without obligation.

How you can tell it is us

No page builder

Every page and every feature is developed for your project, not clicked together from a template.

Direct line to the developer

No ticket ping-pong: you talk to the person who builds your project, in German, English or Greek.

Measured, not guessed

We check load time, accessibility, security and SEO with measuring tools, not by eye. You get the test record.

Your project is yours

Domain, code and content are in your name. You are not tied to us.

Common questions

What does a web app cost?+

It depends on scope. A first usable tool usually starts at 1,500 € net; portals and booking systems are above that. After a conversation you get a binding quote with scope and price.

How long does it take?+

A first version in operation after four to eight weeks, then we extend. We prefer to put something small live early rather than build in the dark for months.

What if I want to change provider later?+

Then you take code, data and documentation with you. There is no licence tied to us and no database only we can read.

Tell us what you have in mind.

We will tell you honestly how we would build it and what it costs. Free first conversation, no obligation.
