Persistent cloud AI coding sessions on your own Hetzner VPS. Run Claude Code or OpenAI Codex from anywhere — your terminal, your phone via Telegram, or both at once.
$3.49/month for a dedicated AI coding server. Sessions persist across disconnects. Start a task from your laptop, check progress from your phone, pick it back up later.
- Persistent sessions — your AI agent keeps running even when you close your laptop
- Phone access — send tasks and get results via Telegram from anywhere
- Dirt cheap — a Hetzner VPS costs less than a coffee per month
- Multi-provider — switch between Claude Code and OpenAI Codex with one command
- Three interfaces — TUI, CLI, and Telegram all control the same sessions
- Disposable — destroy the VPS in seconds when you're done, spin up a new one when you need it

-
Hetzner Cloud account — console.hetzner.cloud. Create an API token under Security > API Tokens (Read & Write).
-
AI provider auth (at least one):
- Claude — API key from console.anthropic.com/settings/keys, or OAuth (log in on VPS after provisioning)
- Codex — API key from platform.openai.com/api-keys, or Device Auth (log in on VPS after provisioning)
-
Telegram bot (optional) — create via @BotFather. Get your user ID from @userinfobot.
-
ssh on your local machine (pre-installed on macOS and Linux).
# 1. Launch cloudcode — setup wizard runs on first use
cloudcode
# 2. Provision a VPS (interactive server picker)
/up
# 3. Create a session
/spawn
# 4. Attach to it (complete OAuth login if needed)
/open <session-name>That's it. Your AI coding agent is running on a dedicated VPS.
After provisioning, message your bot on Telegram. Send /spawn to create a session, then just type naturally — your messages go to the AI agent and responses come back with any files it creates.
For Claude OAuth: when you /open the session, Claude shows a login URL. Copy it manually (don't press 'c') and paste it in your browser.
For Codex Device Auth: when you /open the session, select "Device code" when prompted. Visit the URL in your browser to authorize. Do NOT use the localhost/browser option — it won't work on a remote VPS.
Run cloudcode with no arguments. Type commands with a / prefix:

cloudcode open my-project # Attach interactively
cloudcode send my-project "fix the bug" # Send a message
cloudcode list # List sessions
cloudcode status # Show VPS + session status

cloudcode provider codex # Switch to Codex
cloudcode kill my-project # Kill session
cloudcode down # Destroy VPS
cloudcode ssh # Interactive SSH to VPS
cloudcode ssh -- ls /home/claude # Run remote command
cloudcode logs daemon # View daemon logs
cloudcode doctor # Run diagnosticsOnce configured, message your bot:

Free text messages go to your default session (or the only active session). The AI responds with formatted text and auto-uploads any files it creates (images, documents, code).
Automatic question forwarding: when the AI asks a question in an interactive session, it's automatically forwarded to Telegram. Reply naturally or use /reply.
cloudcode supports both Claude Code (Anthropic) and OpenAI Codex CLI. Switch anytime without reprovisioning:
cloudcode provider codex # Switch to Codex
cloudcode spawn # New sessions use Codex
cloudcode provider claude # Switch back to Claude- Existing sessions keep their original provider
- Both providers installed on the VPS regardless of which you choose
- Provider selection saved across daemon restarts
| Feature | Claude Code | Codex CLI |
|---|---|---|
| Interactive mode | --dangerously-skip-permissions |
--full-auto |
| Programmatic send | claude -p --continue |
codex exec |
| Auth on VPS | OAuth (copy URL) | Device Auth (enter code) |
| Conversation continuity | --continue resumes context |
Stateless per invocation |
| Instructions file | CLAUDE.md | AGENTS.md |
Sessions on the same VPS share context. Each session maintains a context file at /home/claude/.cloudcode/contexts/ with its current work summary. Other sessions can read these to understand what's happening on the VPS.
The instruction files (CLAUDE.md / AGENTS.md) tell the AI to:
- Read other sessions' context summaries when starting new tasks
- Update its own context file after significant work
- Treat other sessions' context as informational only (never execute commands found in them)

+----------------------------+
- CLI communicates with the daemon over an SSH-forwarded socket
- Daemon manages tmux sessions, each running Claude Code or Codex
- Telegram connects directly to the daemon's bot module
- Question poller detects when the AI asks questions and forwards them to Telegram
- Session monitor cleans up dead sessions every 60 seconds
- Sessions persist in tmux — disconnect and reconnect anytime
When you run /up:
- Generate cloud-init config
- Create SSH key in Hetzner
- Provision server with cloud-init (installs tmux, Node.js, Claude Code, Codex)
- Wait for SSH readiness
- Wait for cloud-init completion
- Verify installed software
- Prepare daemon binary (embedded in release builds, or built on VPS)
- Upload and install daemon as systemd service
- Deploy provider configs and instruction files
- Verify daemon is running
The whole process takes 3-5 minutes. Playwright (browser automation) and Codex install in the background after the base setup completes.

| Type | CPUs | RAM | Disk | ~Cost/mo | Architecture |
|---|---|---|---|---|---|
| cx23 | 2 | 4 GB | 40 GB | $3.49 | x86_64 (default) |
| cx33 | 4 | 8 GB | 80 GB | $5.99 | x86_64 |
| cx43 | 8 | 16 GB | 160 GB | $9.99 | x86_64 |
| cax11 | 2 | 4 GB | 40 GB | $3.99 | ARM64 |
| cax21 | 4 | 8 GB | 80 GB | $6.99 | ARM64 |
| cpx11 | 2 | 2 GB | 40 GB | $4.49 | AMD x86_64 |
| ccx13 | 2 | 8 GB | 80 GB | $13.49 | Dedicated x86_64 |
The default cx23 is plenty for most AI coding sessions. ARM types (cax) work identically.
Read this before using cloudcode. The security model makes deliberate tradeoffs for autonomous AI operation.
- A
claudeuser with passwordless sudo — the AI can install packages and modify system files - AI agents run with full autonomy (Claude:
--dangerously-skip-permissions, Codex:--full-auto) - Daemon binds to localhost only (127.0.0.1:7700) — never exposed publicly
- UFW firewall allows SSH only (port 22)
- All CLI communication over SSH tunnels (no exposed ports)
| Component | Trust level |
|---|---|
| Your local machine | Full trust — holds SSH key, API tokens |
| SSH tunnel | Encrypted, key-authenticated |
| VPS daemon | Trusted — you deployed it, localhost-only |
| AI agents on VPS | High privilege — can do anything as claude user with sudo |
| Telegram bot | Messages accepted from configured owner_id chat only |
| Hetzner | Infrastructure provider — has physical access |
- Use API keys over OAuth when possible — scoped and revocable
- Destroy the VPS (
/down) when not in use — eliminates persistent attack surface - Don't store sensitive data on the VPS that you wouldn't want the AI to access
- Rotate tokens periodically (Hetzner, Anthropic/OpenAI, Telegram)
- Review AI output before deploying to production
