From C++ games to
a series that writes itself.
QUAK is a one-person studio that builds things that actually run: AI robots and agents, self-generating live shows, servers, databases, APIs. Built to order — or for ourselves, like Simlokatorzy.
full episode · 42 min Simlokatorzy are here
A Polish animated series that generates itself — in SimWorld: its own scene engine, its own AI director, its own voices, its own server. It runs live on YouTube, but full edited episodes come out too. This is one of them.
Simson sat on the floor and closed his eyes. Mira has questions. Sima has answers — but not all of them can be said out loud.
It ends with a song: "Knock on my door, World".

Story
How we got here
Every chapter is a different technology. The common thread: at some point it had to work.
-
It started with games
The first lines of QUAK code were C++ games. Game loop, collisions, hand-rolled data structures — no framework, no web, plenty of patience. That is where we learned that a working program beats a pretty one.
-
Games go online
Then the games moved to the browser: Quakky, Labyrinth, Adventurer, retro classics. Canvas, sprites, a realtime leaderboard. They are still playable today.
-
Websites, apps, QUAK Learn
QUAK became a company. Business apps for repair shops, wholesalers and offices (Tabelek, TechApp, Creativo), client websites, open-source libraries and the QUAK Learn blog with dozens of articles on architecture, backend and cloud.
-
Agents and our own harnesses
Instead of waiting for off-the-shelf tools, QUAK built its own agent platform: local-first, on our own hardware, with its own runtime and the Jarvis assistant. To us an agent is not a chat box — it is a process with memory, tools and a job to finish.
-
A series that generates itself
All of those chapters meet in Simlokatorzy: games (the scene engine), web (static pages + PixiJS), backend (house server, scene queue, API) and AI (director, screenwriter, voices). An animated series live on YouTube — and proof that QUAK can build an entire system like that from scratch.
Built to order
What we build
QUAK means duck: it flies, walks and swims. Frontend, backend, cloud, AI — one team, one point of responsibility.
AI robots & agents
Agents with memory and tools, voice assistants, integrations with local and cloud models, robotics on our own runtime.
Self-running live productions
AI-generated series and streams: scene engine, director, screenwriter, TTS, lipsync, custom UI and a scene queue — for YouTube and beyond.
Servers, databases, APIs
Backends that survive production: event sourcing, CQRS, migrations of millions of documents, cloud, containers, integration tests.
Apps & games
Web apps for businesses, internal tools, browser games, static sites that load instantly.
Track record
Where we've been
Before Simlokatorzy, QUAK shipped code where bugs are expensive.
Work on a global education app used by students across many markets.
Games for the healthcare industry — where the mechanics have to help, not just entertain.
DTS, DAS and RTTR systems for Polish state-owned enterprises: fibre-optic sensing and realtime monitoring.
Co-building an application for analysing clinical trials run worldwide, on top of a global data warehouse.
Kubernetes Docker GCP Kubernetes, Docker, GCP — daily work, not a scare.
Blog
The posts worth keeping
Out of dozens of QUAK Learn articles, these are the ones we still come back to.
Local voice assistant with Ollama
Microphone → speech recognition → local LLM → voice. A whole assistant on your own machine, nothing sent to the cloud.
"One to rule them all" — a service rebuild story
Rebuilding a service and migrating millions of NoSQL documents on Google Cloud without stopping production.
Bi-Temporal Events
Two clocks in one event: when something happened, and when we found out. Martin Fowler's vision versus practice, "the Arkency way".

Former headliners
Libraries and projects QUAK left on the web. They work, but we no longer develop them.
