# Dropbox — Nova

Nova is Dropbox's internal service for running coding agents in its cloud. Engineers launch parallel sessions from a web UI, CLI, or API, and internal systems call agents inside automated workflows like CI triage and migrations. Callers attach validation commands that Nova runs after each attempt.
