🐙 Promptbook: Invisible AI Agents

Create persistent AI agents that turn your company's scattered knowledge into action - powered by the Agents Server

🚀 Quick deploy

Run the standalone VPS installer (for example on DigitalOcean) only on a fresh server. Interactive mode asks for the installation values:

sudo curl -fsSL https://raw.githubusercontent.com/webgptorg/promptbook/refs/heads/main/install.sh | bash

Non-interactive mode takes defaults from command-line options. Use --env live, --env preview, --env production, or --env lts to pick the installed environment; the default is preview. When --openai-api-key is provided with the default OpenAI Codex runner, the installer installs and configures Codex automatically; other runner authentication can be configured later from the UI or SSH:

sudo curl -fsSL https://raw.githubusercontent.com/webgptorg/promptbook/refs/heads/main/install.sh | bash -s -- \
    --non-interactive \
    --yes-i-understand-that-script-should-be-run-on-fresh-server \
    --env preview \
    --domain my-server.com \
    --openai-api-key sk-proj-xxx \
    --admin-password xxx
