Web apps in .NET and Blazor
Business systems, admin dashboards and portals in ASP.NET Core and Blazor, with a clear architecture that stays easy to extend.
Software house · Katowice, Poland · .NET, Blazor, Rust
Custom software, from the web app down to the kernel.
Artisso designs and builds software for businesses: web apps in .NET and Blazor, integrations with external services, mobile apps and AI features. And to know our tools inside out, we also build our own operating system.
Our code is public. Check us out on GitHub.

01 — Services
We build software that works, from first sketch to production.
Most of our work lives in the .NET ecosystem, but we do not stop at the application layer. When a project needs it, we go down into integrations, databases, mobile devices and the operating system itself.
Identity and security
ASP.NET Core Identity shaped to your project: sign-in screens as Blazor components, custom user stores, roles and permissions.
Integrations and APIs
We connect your system to the outside world: Google Maps and Places, Poland's REGON business registry (BIR), third-party REST and SOAP services, and your own APIs.
Mobile apps
Android and iOS apps in the .NET ecosystem, connected to your backend. Our Xamarin.Forms plugin has more than 5,000 downloads.
Systems software
Kernels, drivers, filesystems and UEFI boot. We build our own operating system, so low-level work does not scare us.
AI in your product
Agents and language models wired in safely: typed actions, clear permission boundaries and human approval instead of magic.
02 — How we work
You talk to the people who write the code.
Artisso is a software house from Katowice, Poland. There are no layers of middlemen: the engineers who gather your requirements are the same ones who design the architecture and write the code, so nothing gets lost along the way.
We work in short iterations and show you working software after each one, not slides. You make the call on every important step. It is the same rule we built OSAIKU around: a person approves, the machine executes.

How a project runs
- Discoverthe problem, not just a feature list
- Planscope, architecture and estimate
- Approveyou sign off on the plan before we start
- Buildshort iterations with a working demo
- Verifytests and code review before each release
- Shipproduction, monitoring and documentation
- Supportmaintenance and growth after launch
03 — Flagship project
OSAIKU: an operating system written from scratch.
The best proof of skill is working code. OSAIKU is our research and development project: an experimental x86_64 UEFI operating system where people and AI agents work together safely, through typed, bounded and human-approved actions.

- Boots via UEFI in QEMU and on a real laptop, from USB or from its internal disk.
- Its own kernel, isolated processes, desktop compositor and USB stack.
- An authenticated copy-on-write filesystem. Documents survive a reboot.
- First experimental release planned for December 2026.
04 — Open source
Code you can review before you ever talk to us.
We release some of our tools as open libraries. It is the quickest way to judge how we write code.
Blazor library
Blazor.Component.Maps
Google Maps and Google Places autocomplete for Blazor apps, with extra support for MudBlazor.
Blazor library
Blazor.Identity.UI
Replaces the Razor pages of Microsoft.AspNetCore.Identity.UI with native Blazor components in a separate library.
Integration
RegonServiceNetStandard
A client for the BIR 1.1 service of Poland's REGON business registry, for .NET Standard 2.0 and .NET Core. Look up companies by NIP and REGON.
.NET library
NetCore.Identity.Dapper
ASP.NET Core Identity backed by Dapper instead of Entity Framework. Works with .NET Core and Blazor.
NuGet package
Xamarin.Plugin.DateTimePicker
A customisable date and time picker for Xamarin.Forms mobile apps.
Unity plugin
UnityTutorialSystem
A Unity plugin that automates building in-game tutorials: dialog windows, overlays and a step editor.
05 — Stack
We pick tools for the problem, not the other way around.
We specialise in .NET, and the same team writes an operating system in Rust. We choose what solves your problem best and what your team can maintain after us.
