Schleuder

Is Schleuder actively maintained?

We cannot measure this one. Schleuder is developed outside the platforms our data source collects activity from, and its repository lives at 0xacab.org — so there is no commit history or release cadence here to score.

Read that as missing data, not as a warning. Several of the best-maintained projects in this catalogue are unrated for exactly this reason. To judge it, open the repository and look at the date of the most recent commit yourself.

What Schleuder actually does

Schleuder is a mailing list manager that incorporates GPG encryption capabilities for message resending. It allows administrators to operate secure mailing lists where correspondence can be automatically encrypted and verified using OpenPGP keys. The software is written in Ruby and distributed under the GPL-3.0 licence.

Best fit: This is suitable for technical groups or privacy-conscious organisations that require end-to-end encrypted email discussions via a central mailing list.

Worth knowing: Setting up and maintaining GPG keys alongside a mailing list server introduces significant operational complexity and administrative overhead for key management. Additionally, the project currently lacks recent release activity or metrics in public repositories.

Deployment notes

As a Ruby application, you will typically need to configure a compatible Ruby runtime environment, a persistent database backend, and a mail transfer agent to handle incoming and outgoing messages.
