Security Consideration

Caution is advised when exposing Transmute to the public internet. While it features built-in authentication and user data isolation, it is designed for trusted networks. If deployed outside of a local network, it is recommended to use a reverse proxy with TLS and rate limiting to mitigate security risks.
