Everything we build,
and what state it is in.

Eight products are running in production today and are managed from a single back office. The rest are in development, and are listed as such — a page that shows an unfinished thing as finished is a page nobody can use to make a decision.

Live in production

Each one runs on the shared platform and is administered from the console →

Lineo

Live

Salon management engineered for flow — bookings, per-stylist scheduling, staff capacity and the service menu on one surface.

Node · Prisma · Flutter getlineo.de →

Yuma

Live

A marketplace for home kitchens: weekly meal plans, custom cakes and the cook two streets away, ordered the way you would order anything else.

Node · Prisma · Flutter getyuma.app →

Katharina

Live

A universal AI browser agent living in the Chrome side panel — it reads the page you are actually on and does the work beside you.

Node · Chrome MV3 katharina.app →

CallTune

Live

Real-time bidirectional call translation. One side speaks Arabic, the other hears natural German, through an interpreter that joins the call invisibly.

LiveKit · Node calltune.avenzasoft.com →

FreeTree

Live

Fruit and nut trees in public space you are allowed to pick from, built on the open tree cadastres of ten European countries.

Node · PostGIS · Flutter console →

Node

Live

The co-living operating system — maintenance tickets, laundry QR timers, a package log and lending, instead of one unreadable house group chat.

Node · PWA open →

SoberCircle

Live

Peer support for recovery. Check-ins, reflections and crisis alerts, with the sensitive material encrypted and deliberately unreadable from the back office.

Node · Prisma open →

ChatTune

Live

A translation overlay for WhatsApp on Android: it reads the chat you have open and draws the translation on each bubble, tracking them as you scroll.

Android · Node · Gemini console →

In development

Building, not yet deployed. No sign-up, no waitlist theatre — they appear above when they are actually running.

Neighborhood Lending

Building

Borrow the drill instead of buying it — a lending marketplace for the things a street already owns, with pickup points kept fuzzy until a loan is agreed.

Flutter · Node · Prisma

Livability

Building

Address intelligence — type an address and understand the place: what is nearby, how loud it is, how well it is connected.

Node · Prisma · PostGIS

AutoAgent

Building

A phone plus a cheap OBD-II interface becomes an AI diagnostic engineer: it maps the vehicle's architecture, finds the fault, and verifies the repair.

Flutter · ESP32 · Node

Breath Sense

Building

Adaptive breathwork that learns how your body responds from real physiological feedback, rather than counting at you on a fixed timer.

Flutter · Node

SunGuard

Building

Sunscreen reminders that fire only when the live UV index and your actual position agree that you need one.

Flutter · Open-Meteo

Lucent

Building

Plan the day as blocks of time. One Flutter codebase across web, iOS and Android.

Flutter

Katharina Network Agent

Building

Describe a network in plain language, watch it built on a real containerlab, and let a mechanical verifier — not the model — decide whether it works.

Electron · FRRouting

Katharina DevOps

Building

An AI infrastructure engineer wired to a real Kubernetes cluster rather than a description of one.

Node · Kubernetes

Katharina ETL

Building

Visual, agent-built, deterministic data pipelines — the agent assembles them, the engine runs them the same way every time.

Electron · Node

Katharina Atlas

Building

The living architecture map — a binding document that stays true as the system underneath it moves.

Node

Katharina Desktop

Building

A desktop runner for automated web extraction jobs, for the work that should not live in a browser tab.

Electron

Web Harvester

Building

Point it at a list page and click one example. Claude writes a reusable extraction recipe; a fixed engine then runs that recipe for free, forever.

Node · Claude API

Parking Sensor

Building

An ESP32, a magnetometer and a microwave radar mounted under the vehicle, reporting occupied or vacant on a battery that lasts because the expensive sensor is off 99.9% of the time.

ESP32 · C

Mithaq

Building

Events and the people at them — feed, detail, availability and check-in, in one premium-minimal surface.

React

Bakery Finder

Building

A Chrome extension that sweeps Google Maps for every bakery and pâtisserie in a country — city by city, keyword by keyword — and exports a deduped CSV.

Chrome MV3

Internal

Tools we run the company on. Listed for completeness; not products anyone buys.

Avenza Admin

Internal

One back office over all eight live products. It stores people and permissions and nothing else — every other number is read from the product that owns it, at request time.

Node · Prisma · React /admin →

This site

Internal

The public page you are reading. No framework, no build step — four stylesheet layers over one set of markup.

HTML · CSS · Three.js

Lucent Harness

Internal

Puppeteer harnesses that render a built Flutter web app and audit it, so a regression is caught by a machine and not a person scrolling.

Node · Puppeteer

CAPTCHA Fallback

Internal

A zero-cost local service for evaluating the anti-bot tier of endpoints we own, so our own crawlers degrade politely instead of hammering.

Python

Build on the AvenzaSoft network.

Tell us what you are connecting, and we will tell you honestly whether we are the layer for it.
