XHCGroup

Building open
infrastructure.

XHCGroup is an independent team building free public infrastructure and low-level tools — maintained for the long run, in the open-source spirit.

A good product starts with a clear idea. We build the parts of the internet that should be free and reliable — names, storage, encryption — and we keep them running.

Good products begin with a clear idea. We build the parts of the internet that should be free and reliable — domains, storage, encryption — and maintain them for the long haul.

01 — About the studio

A small team that takes infrastructure seriously.

XHCGroup is made of independent developers, spanning the full self-built chain from frontend to kernel, from compression algorithms to operating systems. We don’t pile on third-party components — we keep the complexity to ourselves and the simplicity for our users.

Whether it’s a free public service or a self-built low-level technology, we design with long-term maintenance in mind — no chasing trends, just solid fundamentals.

02 — What we do

From domains to kernel, built in-house.

A / 01

Public infrastructure

Free subdomains, full DNS management, and end-to-end encrypted cloud storage with SSL issuance — open to every developer.

B / 02

Self-built crypto & compression

XEBZ extreme-compression containers, and XHC-SS speed-first crypto kernel Combo2 — security and efficiency together.

C / 03

Systems & distro

XHCOS self-built Linux distribution, the ExiFS filesystem, and an original toolchain — from disk format to UI, all in-house.

03 — Selected works

Things we’ve built.

04 — Infrastructure

We don’t work alone.

A lot of the low-level work runs on infrastructure we trust. DNS and delivery are provided by Cloudflare; everything else is self-hosted and maintained by the team — reliable and under our control.

05 — Tech stack

Built from the ground up.

From kernel to UI, we build as much in-house and under our control as possible. Below are the main technologies behind this infrastructure — battle-tested low-level components alongside our own original implementations.

06 — Story so far

So far.

  1. 2025

    XHCGroup founded

    Starting from the idea of "free and reliable infrastructure," we began building public services and low-level tools.

  2. 2026

    XHCDNS free subdomains go live

    Free subdomains and full DNS management open to developers, maintained steadily for the long run.

  3. 2026

    XHC Drive and XEBZ released

    AES-256 end-to-end encrypted drive launched; XEBZ extreme-compression containers and the Combo2 crypto kernel keep getting refined.

  4. 2026

    XHCOS and more original projects

    The self-built Linux distribution XHCOS kicks off; original projects like cpu-db and nekos.uk go public one by one.

  5. 2026 · H2

    XEBZ v2.5 and XHC-SS SpeedSafe

    The XHCZ6 compression kernel chases extreme ratios; the speed-first XHC-SS I (v2.6) ships with the Combo2 crypto kernel by default.

  6. 2026 · H2

    XHCOS family and 159 free mail

    XHCOS 2.0 / 14.04 Legacy / Lite (optimized for low-end hardware) run in parallel; the free 159.email mailbox opens.

  7. 2026 · 11

    Windows Media Center recreation goes live

    A pixel-perfect WMC recreation using official assets: five boot animations and photo/music/video hubs, running on Cloudflare Workers (wmc.xsite.dev).

  8. 2026 · 11

    TrustMe SSL issuance platform

    Launched a self-service free SSL certificate service (ca.xsite.dev): one-click issuance via ACME/Let’s Encrypt, with a built-in TrustMe private CA so the issuer shows as TrustMe.
