Codex
Codex supports non-interactive operation through codex exec. Official documentation describes scripts, CI and scheduled tasks with preconfigured permissions.
Promptbook and Codex
Do you need a tool for your development process, or recurring work delivered as a business service?
Promptbook
An ongoing workflow using your files and context. The engine runs in your environment, controls are separate, and a partner who knows your business can handle deployment.
When to consider Codex
Consider it for direct coding work and your own development automations.
When to consider Promptbook
Promptbook uses coding harnesses as building blocks, adding ongoing workflows, company context and partner delivery. Background operation alone is therefore not an exclusive Promptbook advantage.
Try the same process
Use your own materials to compare output quality, oversight required, total cost and handover into operation. Look beyond the licence price or a single impressive output.
