What we run, explained properly.

Waguri is our main product. She moderates Discord servers by reading the conversation around a message, checking it against that server's own rules, and acting on the right person. She also chats, remembers people, and talks in DMs. Server owners configure everything from a web dashboard at waguri.xyz.

How moderation works

Images, videos and GIFs get a fast first check. Anything flagged goes to a vision model for a second opinion and a written description, and a separate review step decides whether it actually breaks the rule. Nobody is muted or has a message removed on a score alone. If the review says it was a false alarm, nothing happens and the image is remembered so it isn't checked again.

Text is checked for slurs, threats and coordinated abuse at the same time, and text inside images gets the same treatment.

When she's not sure

Serious calls like bans and long timeouts always wait for a human. Anything ambiguous is filed for staff with the evidence attached. Every action is logged with the reasoning and the exact message, so moderators can review it or reverse it, and members can appeal.

Safety

Messages about self-harm are never treated as rule-breaking. They're taken out of public view and passed privately to a human moderator. Known child sexual abuse material is matched by hash against industry lists before anything else happens, it is never shown to moderators, and any report that's required is made by a person.

Keeping usage fair

Waguri serves many servers from one place, so every AI request goes through a shared priority queue: moderation first, then chat. No single server can take every slot, chat is rate-limited per person and per server, and she politely declines to write code or long essays so nobody can use her as a free generator.

Anime Hideout is the web home of an anime Discord community: profiles, a feed, direct messages, voice and video calls, moderation tools and a proper appeals process. It ships with a desktop app that has its own installer and update channel.

It's where a lot of our web work was first proven, and it still runs every day. People sign in with Discord.

Kurono is an operating system written from scratch in freestanding C++17 and x86 assembly. There's no C standard library in the kernel and no existing kernel underneath it. One bootable image holds a native desktop, a Linux-compatible system-call layer, a Windows command environment, a package and update pipeline, and a Type 1 hypervisor.

Hardware

It boots on real x86_64 machines as a Multiboot2 kernel, with EFI loaders, a recovery path and installers for FAT32 and ext4. There are nineteen core drivers, a wireless layer, a full TCP/IP stack, and a display manager that handles BGA, VirtIO, Intel, NVIDIA and AMD graphics, including Optimus-style hybrid laptops.

Multiple processors

Every core boots and runs kernel code in parallel. Secondary cores run Linux programs alongside the desktop and are properly preemptive, each with its own timer.

Running real software

The Linux layer supports threads, futexes, event polling and file-descriptor passing, with an ELF dynamic linker and a Wayland compositor inside the kernel. The hardest test so far is Firefox: a full Firefox 140 ESR build boots across the secondary cores, loads a page over Kurono's own network stack, and draws it through the in-kernel compositor. Getting there exposed three real kernel bugs, all fixed.

Security

A whole-system audit found about sixty-eight issues, and around twenty confirmed memory-safety bugs have been fixed so far, including remotely triggerable overflows in the D-Bus code and a guest-to-host escape through the 9p filesystem. That work is ongoing.

Kaiten adds NVIDIA DLSS 4, both Super Resolution and Frame Generation, to Minecraft Java Edition 1.21. It's built on a fork of VulkanMod and the NVIDIA Streamline SDK.

The hard part is fitting a modern upscaling and frame-generation pipeline into a renderer that was never designed for one, which means working at the graphics API level rather than in the game itself.

We run our own email instead of renting it: a Stalwart mail server, a webmail client whose IMAP and SMTP driver we wrote ourselves, and a multi-tenant panel for managing domains and addresses.

SPF, DKIM and DMARC are enforced on every domain, reverse DNS is aligned, and signing is checked with real round-trip tests. Nobody can add an address on a domain until they've proven they own it through DNS.

Our products run on servers we set up and operate ourselves. Public traffic comes in through Cloudflare and a single nginx reverse proxy; every internal service listens only on the local machine. Credentials live in locked-down environment files, never in source code.

AI features use hosted models from commercial providers, with automatic failover between them, spend tracking, and hard daily caps. We used to run our own GPU for this and retired it, so we don't claim otherwise.

We don't currently host apps for outside customers. If you have infrastructure work in mind, email [email protected]. More detail on the engineering page.

We take on a small number of commissioned projects when the work suits us. Every engagement starts with a written scope, agreed by both sides, that sets out what gets delivered, when, and on what terms, before any work begins.

Email [email protected] with what you're trying to do, what it needs to do, and your timeline. The terms are in our project agreement.
