Three self-hosted machines run my public sites, their databases and an AI agent in production: Docker Compose on bare metal behind Traefik, with public traffic arriving through Cloudflare Tunnel. Self-hosted GitHub Actions runners (GARM, one ephemeral Incus VM per job) build each image once; a deploy gate ships that exact digest to UAT, runs Playwright, and promotes the same digest to production. The platform also runs full LGTM observability with Telegram alerts, nightly backups copied offsite to Backblaze B2 with an append-only key, and a control panel that compares every service's version with GitHub and triggers pulls, stack updates and installers.

llama.cpp serving Qwen3.5-9B on my own hardware, with per-client API keys and Prometheus metrics; it powers the guide assistant inside app.staysy.co. Next to it sit a RAG pipeline (an embeddings server and the Chroma vector database) and a Telegram AI agent on an isolated Docker network that can reach the model server but not the database, with its memory backed up nightly.

Your personal AI agent on a USB stick. Plug it into any computer you own and your agent runs there, with everything it knows about you, and every copy keeps learning and shares what it learns with the others. Built and tested as a single static Go binary for Linux, macOS and Windows, it keeps its memory encrypted on the stick and in a private git repo with keys only you hold, learns append-only so that forgetting is a deliberate, recorded act, and runs every action through a three-layer sandbox: the model proposes, a rule-keeper checks it against your signed constitution, and only then does the agent act.

playthis.today is an arcade of browser games, served as a static site that deploys on every merge to main. Alongside it, The Game (tg.playthis.today) is a viral Go and SQLite web app: open the link, lose The Game, then generate a shareable link to pass it on. Both are self-hosted; The Game adds rate limiting and a hardened security policy.
