OmniRoute Docker deployment and coding routes

One OmniRoute instance and one Open WebUI chat front end behind an existing HTTPS reverse proxy. OmniRoute's dashboard/API use port 20128, and Open WebUI uses port 3005; Docker publishes both only on the host's 172.17.0.1 address. Use two independent Compose projects at /srv/root/compose/omniroute/compose.yml and /srv/root/compose/webui/compose.yml.

This is a proposed configuration for coding in CSS, HTML, JavaScript, Go, Rust, Kotlin, PowerShell, Nushell, fish, zsh, bash, and POSIX sh/dash. It defines the deployment settings, including daily model/pricing sync, and routes requests using your own Claude and GPT model names. Provider accounts, ordered combos, and incoming-name mappings are configured in OmniRoute's dashboard after startup; environment variables alone do not create those routes.

Files

Save the following four code blocks as compose.yml and .env.example in each named directory. Each Compose file uses its own private .env.

Is my Plex server hacked?

A one-file, read-only script (plex-check.sh) you can run on any server to check whether a Plex Media Server install shows signs of compromise via the Plex2Shell exploit chain and the malware dropped by it in the wild.

Background: what is Plex2Shell?

In October 2026, a chain of four Plex Media Server bugs was published with a working PoC (CVE-2026-96652, -96654, -96655, -96656). Chained together, they allow **unauthenticated

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.
