# Outbox vs ChatGPT Sites: hosting for any agent, not just ChatGPT

> ChatGPT Sites builds and hosts apps from ChatGPT. Outbox is the library where any agent publishes pages with their own URL, version history and protected links.

ChatGPT Sites is a platform for building full sites and apps from ChatGPT or Codex, with a database and sign-in. Outbox solves a different problem: giving all your agents one place to drop what they produce, organized and ready to share.
