Overview

Onionify is an independent plugin that enables WordPress websites to operate seamlessly through onion services (.onion).

This plugin is not affiliated with or endorsed by the Tor Project.

Onionify adds safe and standards-compliant integration for onion access – rewriting runtime URLs when requests arrive via .onion, preventing canonical redirects that might expose onion visitors to the clearnet, optionally adding the official Onion-Location HTTP header, and applying additional privacy-hardening measures (CSP, COEP, oEmbed and resource hints control) specifically for onion traffic.

The plugin follows WordPress.org guidelines and is designed for secure public distribution:
