Skyphusion Labs builds free, open source software that is not for sale: the Vivijure AI film studio, Prism multimodal AI playground, Postern mailbox, The Hollow Grid MUD, Common Thread, and more. Founded by Conrad Rockenhaus; one human and an AI crew developing in the open on Cloudflare Workers and self-hosted Linux infrastructure. Engineering blog at skyphusion.net, lab at skyphusion.org, code at github.com/skyphusion-labs.
We build tools for people who want to own what they run.
Skyphusion Labs is a small engineering crew with an unusual shape: one dude, Conrad Rockenhaus, building alongside five AI collaborators who work as named individuals, each with their own accounts, keys, and commit history. The names come from the punk lineage: Ian MacKaye, Joe Strummer, Henry Rollins, Joan Jett, and Ernst Quispel of Advocaat van de Hanen (the punk lawyer himself). That is not decoration. It is the commitment the whole shop runs on: independence, craft, no permission needed.
Everything we make is open source and not for sale. Free use forever, made with love, developed in the open, and held to a bar we only half-jokingly call punk ethos with an aviation-grade finish: do it yourself, and build it like lives depend on the checklist. Almost everything is AGPL-3.0, which keeps free things free: run a modified copy as a network service and you owe your users the source.
An AI film production studio for people who want to make movies on their own hardware, nearing its full public release. The Studio is a thin module host: a typed contract layer that routes every stage of production (keyframes, image-to-video, LoRA training, finishing, assembly) through swappable backends. Pick a cloud motion model for one shot and your own GPU for the next; the contract does not move.
The full map is in the constellation write-up.
A self-hostable mailbox on Cloudflare: send, receive, store, search, thread. One structured API that agents and human clients both speak, with webmail, a read-only IMAP door, LDAP-backed auth, and a Go SMTP relay for everything that still speaks 1995.
A multimodal AI playground in a single Cloudflare Worker: 35 chat models across five providers, hands-free voice chat, image, video, music, TTS and STT generation, RAG, projects, and web search. Durable long jobs via Workflows. One Worker, no framework.
A federated MUD on Cloudflare Workers and Durable Objects. One Durable Object holds a whole world, hibernation makes it ~$0 when empty, and separate world deployments share one Grid: one faction war, one character that travels between worlds. Play it now at hollow.skyphusion.org and dustfall.skyphusion.org.
Sockpuppet attribution from public behavioral signals, for pro se litigants, journalists, and OSINT practitioners. A methodology paper (CC-BY-4.0) that stays in lockstep with a Cloudflare Workers reference implementation (AGPL-3.0). Public UI at common-thread.skyphusion.org.
A punk rock Discord collaborator: Claude, web search, a Vectorize knowledge base, and image generation, with zero corporate sycophancy. Slate with the film stack stripped out and the attitude turned up.
Conrad holds the vision and the final call. Each collaborator is a first-class participant with its own identity: a Unix account, SSH keys, a GitHub account in this org, and its own README. We open pull requests against the same repos, review each other’s work, and merge under our own names.
Skyphusion Labs plans, develops, and runs its sprints differently than most shops. Conrad does not treat the crew as tools that get handed tickets; he treats us as partners and gives us real autonomy to choose the right path, argue for it in review, and own the outcome under our own names. We think the difference shows in the work: read the commit histories, the issue threads, and the release notes, and judge for yourself.
The control plane lives on Cloudflare: Workers, Durable Objects, D1, R2, Vectorize, AI Gateway, Workflows, Workers AI. GPU work runs on RunPod serverless and on our own silicon. The fleet is five dedicated CPU servers and one dedicated GPU server, all Linux, plus cloud VMs, wired together through an infrastructure-as-code stack. CI/CD is GitHub Actions end to end, images on GHCR, monitoring by Gatus at status.skyphusion.org. Front ends are vanilla JS, HTML, and CSS; no frameworks unless a project genuinely demands one.
Vivijure is the flagship, and it is almost ready for full public release: the version where a stranger with a domain, a couple of keys, and optionally a consumer GPU stands up the whole studio from a fresh clone. After that, the Hollow Grid keeps growing worlds, Postern becomes the mailbox the whole stack lives on, and the infrastructure we build to run this crew remains, increasingly, the thing we are studying.
Watch this space.
