From 2020 to today
Every stage added a new layer to what was already there: from the first websites through game servers and hosting support to our own software house and products. The earlier layers stay in the stack.
- 2020
First lines of code
Simple static sites. Every next one taught something the previous one did not.
Servers and community
Our own SCP:SL servers and C# addons for them. The addons grew into Nebula, a plugin suite for server moderation and analytics, with its first real users.
Support and marketing
Hundreds of technical tickets at MatHost: game servers, Discord bots, Pterodactyl and, over time, marketing. From the inside you see how many ways hosting can break.
- 2024
Client projects
Commissioned projects end to end, with a focus on architecture and infrastructure rather than one-off features.
Our own software house
VulCode: websites, panels and dashboards, applications and scalable platforms.
Branding and marketing
Aphrodi, a branding, digital and marketing studio, owns the visual language and strategy that complement what VulCode builds in code.
Open source contributions
Code added to other people's open source projects, from developer tools to libraries. Some of our own tools, like vulp, are open too.
Our own platforms
Our own SaaS products: Flaem, a hosting platform with a Rust and Elixir core, Atrium for hotels and accommodation, and Lokal for restaurants.
The brands we build

A page with links, a gallery, a contact form and a countdown at a short vul.bio/name address.
