Spawn

Launch any AI agent on any cloud with a single command. Coding agents, research agents, self-hosted AI tools — Spawn deploys them all. All models powered by OpenRouter. (ALPHA software, use at your own risk!)

10 agents. 10 clouds. 99 working combinations. Zero config.

Install

curl -fsSL https://openrouter.ai/labs/spawn/cli/install.sh | bash

Or install directly from GitHub:

curl -fsSL https://raw.githubusercontent.com/OpenRouterTeam/spawn/main/cli/install.sh | bash

Usage

spawn                         # Interactive picker
spawn <agent> <cloud>         # Launch directly
spawn matrix                  # Show the full agent x cloud matrix

Examples

spawn                                    # Interactive picker
spawn claude sprite                      # Claude Code on Sprite
spawn codex hetzner                      # Codex CLI on Hetzner
spawn claude sprite --prompt "Fix bugs"  # Non-interactive with prompt
spawn codex sprite -p "Add tests"        # Short form
spawn claude                             # Show clouds available for Claude
spawn delete                             # Delete a running server
spawn delete -c hetzner                  # Delete a server on Hetzner

Without the CLI

Every combination works as a one-liner — no install required:

bash <(curl -fsSL https://openrouter.ai/labs/spawn/{cloud}/{agent}.sh)

Non-Interactive Mode

Skip prompts by providing environment variables:

# OpenRouter API key (required for all agents)
export OPENROUTER_API_KEY=sk-or-v1-xxxxx

# Cloud-specific credentials (varies by provider)
# Note: Sprite uses `sprite login` for authentication
export HCLOUD_TOKEN=...           # For Hetzner
export DO_API_TOKEN=...           # For DigitalOcean

# Run non-interactively
spawn claude hetzner

You can also use inline environment variables:

OPENROUTER_API_KEY=sk-or-v1-xxxxx spawn claude sprite

Get your OpenRouter API key at: https://openrouter.ai/settings/keys

For cloud-specific auth, see each cloud's README in this repository.

Troubleshooting

Installation issues

If spawn fails to install, try these steps:

1. Check bun version: spawn requires bun >= 1.2.0

   bun --version
   bun upgrade  # if needed
   

2. Manual installation: If auto-install fails, install bun first

   curl -fsSL https://bun.sh/install | bash
   source ~/.bashrc  # or ~/.zshrc for zsh
   curl -fsSL https://raw.githubusercontent.com/OpenRouterTeam/spawn/main/cli/install.sh | bash
   

3. PATH issues: If spawn command not found after install

   # Add to your shell config (~/.bashrc or ~/.zshrc)
   export PATH="$HOME/.local/bin:$PATH"
   

Agent launch failures

If an agent fails to install or launch on a cloud:

1. Check credentials: Ensure cloud provider credentials are set

   # Example for Hetzner
   export HCLOUD_TOKEN=your-token-here
   spawn claude hetzner
   

2. Try a different cloud: Some clouds may have temporary issues

   spawn <agent>  # Interactive picker to choose another cloud
   

3. Use --dry-run: Preview what spawn will do before provisioning

   spawn claude hetzner --dry-run
   

4. Check cloud status: Visit your cloud provider's status page

   • Many failures are transient (network timeouts, package mirror issues)
   • Retrying often succeeds

Getting help

• View command history: spawn list shows all previous launches
• Rerun last session: spawn last or spawn rerun
• Check version: spawn version shows CLI version and cache status
• Update spawn: spawn update checks for the latest version
• Report bugs: Open an issue at https://github.com/OpenRouterTeam/spawn/issues

How it works

Each cell in the matrix is a self-contained bash script that:

1. Provisions a server on the cloud provider
2. Installs the agent
3. Injects your OpenRouter API key so every agent uses the same billing
4. Drops you into an interactive session

Scripts work standalone (bash <(curl ...)) or through the CLI.

Development

git clone https://github.com/OpenRouterTeam/spawn.git
cd spawn
git config core.hooksPath .githooks

Structure

{cloud}/lib/common.sh    # Cloud provider primitives (provision, SSH, cleanup)
{cloud}/{agent}.sh        # Agent deployment script
shared/common.sh          # Shared utilities (OAuth, logging, SSH helpers)
cli/                      # TypeScript CLI (bun)
manifest.json             # Source of truth for the matrix

Adding a new cloud

1. Create {cloud}/lib/common.sh with provisioning primitives
2. Add to manifest.json
3. Implement agent scripts using the cloud's primitives
4. See CLAUDE.md for full contributor guide

Adding a new agent

1. Add to manifest.json
2. Implement on 1+ cloud by adapting an existing agent script
3. Must support OpenRouter via env var injection

Contributing

The easiest way to contribute is by testing and reporting issues. You don't need to write code.

Test a cloud provider

Pick any agent + cloud combination from the matrix and try it out:

spawn claude hetzner      # or any combination

If something breaks, hangs, or behaves unexpectedly, open an issue using the bug report template. Include:

• The exact command you ran
• The cloud provider and agent
• What happened vs. what you expected
• Any error output

Request a cloud or agent

Want to see a specific cloud provider or agent supported? Use the dedicated templates:

• Request a cloud provider
• Request an agent
• Request a CLI feature

Requests with real-world use cases get prioritized.

Report auth or credential issues

Cloud provider APIs change frequently. If you hit authentication failures, expired tokens, or permission errors on a provider that previously worked, please report it — these are high-priority fixes.
