VulCode experience: projects, products and contributions since 2020

Instead of promises: what we have built, for whom, in which technologies and whose code accepted our changes. Every number on this page is counted from data with each release of the site.

What we have built

Portfolio projects by type: 92 projects over 6 years since the first websites in 2020. Each square is one project, and each type has its own list with descriptions in the portfolio.

Projects worth starting with

One project of each kind: a website, a panel, a client build, a desktop app, a tool and a game.

VulCode client panel

VulCode client panel

The client panel for our own brand: projects, billing, an affiliate program with automatic commission payout and support tickets.

See the project: VulCode client panel
WaveHost

WaveHost

A new website for a hosting brand: a multi-page site with transparent pricing, trust-building sections and a server configurator.

9 Jun 2026A solidly built website and a professional approachVulcode.com built our website and we are very happy with the result. The site runs smoothly, is well optimised and displays correctly on every device. The whole rollout went without a hitch, and the source code is clean and ready for further development. We appreciate the punctuality and the technical support at every stage.SzymonCEO, WaveHost

Our own products

Software we write and run ourselves. We test solutions on it before they go into client projects.

  • Flaem: A panel for hosting companies, game servers, VPS, domains and mail in one.

    Flaem

    A panel for hosting companies: game servers, VPS, domains and mail in one. Flaem runs the whole service lifecycle: the client buys, the node provisions, the panel keeps track of payments, limits and live metrics. You see the entire fleet, the client gets a console, files and full control over their server. For hosting companies and teams selling game servers, VPS and webhosting. Flaem in the Ecosystem

  • Plazer: A messenger that has no idea what you are talking about.

    Plazer

    A messenger that has no idea what you are talking about. Messages, servers with channels, voice calls and profiles in one lightweight app. Your device encrypts direct messages, groups and private channels, the code is open, and you can host the server for your community yourself. For teams and communities that want their own place to talk instead of yet another chat that belongs to someone else. Plazer in the Ecosystem

  • Gyred: A control plane for AI agents that work on their own.

    Gyred

    A control plane for AI agents that work on their own. Gyred keeps a fleet of agents in line: workspaces separate projects, rules say what an agent may do, and loops carry a real stopping condition instead of spinning forever. Leases make sure two agents never grab the same task: one takes it, the rest wait. For us, and for anyone running many AI agents at once who needs a single desk to watch them from. Gyred in the Ecosystem

  • Atrium: A panel for hotels and guesthouses with a live floor map.

    Atrium

    A panel for hotels and guesthouses with a live floor map. Atrium shows the hotel the way it really looks: a floor map with live room statuses, a 14-day booking gantt, housekeeping and maintenance in one flow. Reception clicks a room and knows everything. For hotels, guesthouses and apartments, from a few rooms to a few floors. Atrium in the Ecosystem

  • Lokal: A live floor plan, reservations and the kitchen in one panel.

    Lokal

    A live floor plan, reservations and the kitchen in one panel. The floor plan shows live who is seated, what they ordered and which table is waiting. Reservations guard against collisions on their own, orders go straight to the kitchen screen, and inventory follows the sales. For restaurants, bistros and cafes, wherever the floor has to stay alive. Lokal in the Ecosystem
