# Deploy and Host Odysseus AI Workspace on Railway

![Odysseus self-hosted AI workspace](https://res.cloudinary.com/dh2nt6hgh/image/upload/v1780982827/Screenshot_2026-06-09_at_10.56.59_AM_i70jx3.png)

Odysseus is the self-hosted AI workspace built by PewDiePie — chat, persistent memory,
RAG document search, private web research, agent workflows, email tools, Playwright browser
automation, and push notifications, all in one platform. Connect Claude, GPT-4o, Gemini,
OpenRouter, or any OpenAI-compatible endpoint. Every conversation, memory, and document
stays on your Railway instance — nothing shared with any third-party platform.

This template deploys the complete four-service Odysseus stack: the web app, ChromaDB for
vector memory, private SearXNG for web search, and ntfy for push notifications — all
pre-wired over Railway's private networking with persistent volumes.

## What This Template Deploys

| Service | Purpose |
|---|---|
| **Odysseus** | The AI workspace — chat, agents, memory MCP, document RAG, email tools, Playwright browsing, and model management. Public HTTPS on port `8000` |
| **ChromaDB** | Vector database — stores embeddings for persistent memory and RAG document retrieval. Private service at `/data` |
| **SearXNG** | Private metasearch engine — powers Odysseus web research without any external search API key. Private service |
| **ntfy** | Push notification service — sends alerts and reminders from Odysseus workflows to any device. Private by default |

Only the Odysseus web app is publicly accessible. ChromaDB, SearXNG, and ntfy communicate
with Odysseus over Railway's private internal network — never exposed publicly.

## About Hosting Odysseus

Running Odysseus in production requires four coordinated services with private networking,
persistent volumes, and shared credentials. Without a managed host, you're configuring
Docker Compose, inter-service networking, SearXNG settings files, and SSL manually.

Railway pre-wires all four services over private networking with auto-generated admin
credentials and persistent volumes — public HTTPS domain for Odysseus UI provisioned
automatically.

Typical cost: **~$5–10/month** on Railway's Hobby plan. ChatGPT Plus costs $20/month per
user with no persistent cross-session memory, no private web search, and no self-hosted
option. Odysseus gives your whole team all of that at flat compute cost.

---

## Deploy in Under 5 Minutes

1. Click **Deploy on Railway** — all four services build automatically (~3–5 minutes)
2. Go to the **odysseus** service → **Variables** tab to find your auto-generated
   `ODYSSEUS_ADMIN_PASSWORD` (Railway generates it from `${{secret(32)}}` at deploy time)
3. Open your Railway public URL and log in with `admin` and the generated password
4. Go to **Settings → Models** and add your LLM provider API key
5. Set **Claude Sonnet 4.6** as your default model — required for Memory MCP and tool-use
   workflows (Haiku may skip tool calls on complex tasks)

No SSH. No Docker configuration. No manual service wiring.

## Common Use Cases

- **PewDiePie's self-hosted AI workspace** — run the same AI workspace built by PewDiePie
  on your own Railway infrastructure; all conversations, memories, and documents stay on
  your instance with no data shared to any AI platform
- **Self-hosted alternative to ChatGPT Plus with persistent memory** — unlike ChatGPT's
  limited cross-session memory, Odysseus stores all memories in ChromaDB with full RAG
  retrieval — your AI assistant remembers everything you've told it, permanently
- **Private AI research assistant with web search** — Odysseus uses a private SearXNG
  instance for web research without leaking your queries to Google or Bing; no Tavily API
  key required for basic web search
- **AI agent workspace with document RAG** — upload PDFs, notes, and documents; Odysseus
  indexes them into ChromaDB and retrieves relevant context automatically during chat
- **Multi-model AI workspace** — switch between Claude, GPT-4o, Gemini, DeepSeek, or any
  OpenRouter model without losing memory, documents, or chat history
- **Autonomous agent workflows with Playwright** — agents browse websites, fill forms,
  and extract data via built-in Playwright browser automation

## Configuration

| Variable | Required | Description |
|---|---|---|
| `ODYSSEUS_ADMIN_USER` | ✅ Pre-set | `admin` — your login username |
| `ODYSSEUS_ADMIN_PASSWORD` | ✅ Auto-generated | Check the odysseus service **Variables** tab after deploy for the generated value |
| `AUTH_ENABLED` | ✅ Pre-set | `true` — required for public Railway deployment |
| `LOCALHOST_BYPASS` | ✅ Pre-set | `false` — disables localhost auth bypass for public access |
| `DATABASE_URL` | Pre-set | `sqlite:///./data/app.db` — SQLite stored at `/app/data` |
| `CHROMADB_HOST` | Auto-wired | `${{chroma.RAILWAY_PRIVATE_DOMAIN}}` — private ChromaDB hostname |
| `SEARXNG_INSTANCE` | Auto-wired | `http://${{searxng.RAILWAY_PRIVATE_DOMAIN}}:8080` — private SearXNG URL |
| `NTFY_BASE_URL` | Auto-wired | `http://${{ntfy.RAILWAY_PRIVATE_DOMAIN}}:80` — private ntfy URL |
| `OPENAI_API_KEY` | Optional | OpenAI GPT-4o / GPT-4o-mini API key |
| `OLLAMA_BASE_URL` | Optional | Remote Ollama endpoint for local model access |
| `TAVILY_API_KEY` | Optional | Tavily Search API key for enhanced web research |
| `HF_TOKEN` | Optional | Hugging Face token for private model access |

> **Find your password:** odysseus service → **Variables** tab → copy the generated
> value of `ODYSSEUS_ADMIN_PASSWORD`. Changing this after first setup does not reset the
> existing admin account — the password is stored in the `/app/data` volume.

## Dependencies for Odysseus Hosting

- Railway account — Hobby plan (~$5–10/month) for the four-service stack
- API key from at least one LLM provider — Anthropic Claude Sonnet 4.6 recommended for
  Memory MCP and tool-use workflows
### Deployment Dependencies

- [Odysseus GitHub Repository](https://github.com/pewdiepie-archdaemon/odysseus) — source
- [Odysseus Website](https://pewdiepie-archdaemon.github.io/odysseus/) — documentation
- [ChromaDB Docs](https://cookbook.chromadb.dev/running/running-chroma/) — vector DB reference
- [SearXNG Settings](https://docs.searxng.org/admin/settings/index.html) — search config
- [ntfy Documentation](https://docs.ntfy.sh/config/) — notification configuration

### Implementation Details

Only `odysseus` gets a public domain. ChromaDB, SearXNG, and ntfy are internal-only,
accessible via `RAILWAY_PRIVATE_DOMAIN` reference variables. All persistent data survives
redeploys: chat at `/app/data`, vectors at `/data`, SearXNG config at `/etc/searxng`,
ntfy cache at `/var/cache/ntfy`. FastEmbed embeddings cache at `/app/data/fastembed` to
avoid re-downloading on each restart.

## Frequently Asked Questions

**What is Odysseus and who built it?**
Odysseus is an open-source self-hosted AI workspace created by PewDiePie (GitHub:
`pewdiepie-archdaemon`). It combines chat, persistent memory via ChromaDB, private web
search via SearXNG, document RAG, agent workflows, Playwright browser automation, email
tools, and push notifications in a single self-hosted platform.

**Why does this template use four services?**
Each service handles a specific function: Odysseus runs the main web app; ChromaDB stores
vector embeddings for memory and RAG; SearXNG provides private web research without
external API keys; ntfy delivers push notifications. All four run on Railway's private
network so only the Odysseus UI is publicly accessible.

**How much does Odysseus cost on Railway?**
Approximately $5–10/month on Railway's Hobby plan for all four services. LLM API costs
are separate — Claude Sonnet 4.6 is recommended for Memory MCP but Claude Haiku or
GPT-4o-mini work for basic chat at lower inference costs.

**Where do I find my login password after deploy?**
Open the **odysseus** service in your Railway project → **Variables** tab → find
`ODYSSEUS_ADMIN_PASSWORD`. Railway generates the value from `${{secret(32)}}` at deploy
time. Use `admin` as the username and that generated value as the password.

**Why does Memory MCP require Claude Sonnet instead of Haiku?**
Haiku sometimes skips tool calls and answers directly. Sonnet 4.6 reliably calls
`mcp__memory__manage_memory` for memory operations. Switch to Haiku only after confirming
Memory MCP works with Sonnet.

**Does Odysseus work without local GPU resources?**
Yes. This template uses external LLM APIs — Claude, GPT-4o, or any OpenRouter model. It
does not run local inference on Railway. For Ollama, point `OLLAMA_BASE_URL` to a separate
GPU-enabled instance.
