hydroxide
A third-party, open-source ProtonMail bridge. For power users only, designed to run on a server.
hydroxide supports CardDAV and SMTP.
Rationale:
- No GUI, only a CLI (so it runs in headless environments)
- Standard-compliant (we don't care about Microsoft Outlook)
- Fully open-source
Usage
Your credentials will be stored on disk encrypted with a 32-byte random password. When configuring your client, you'll need this password.

CardDAV
You must setup an HTTPS reverse proxy to forward requests to hydroxide.
hydroxide carddav
Tested on GNOME (Evolution) and Android (DAVDroid).
SMTP
For now, it only supports unencrypted local connections.
