Synapse
I have a simple fork of Wonderfall’s hardened Synapse Docker image with the Mjolnir module support and the default (as opposed to light) variant of the Hardened Memory Allocator.
You can obtain the image by pulling ghcr.io/tommytran732/synapse or quay.io/tommytran732/synapse.
Matrix.to
I made an Alpine Docker container for Matrix.to that you obtain by pulling ghcr.io/tommytran732/matrix.to. The default instance has been changed from Element.io to ArcticFoxes.net.
