[Synapse](https://github.com/matrix-org/synapse) is a [Matrix](https://matrix.org/) implementation written in Python.
### Notes
- Prebuilt images are available at `ghcr.io/tommytran732/synapse` and `quay.io/tommytran732/synapse`.

- Don't trust random images: build yourself if you can.
- Always keep your software up-to-date: manage versions with [build-time variables](https://github.com/TommyTran732/Synapse-Docker/blob/main/Dockerfile#L1-L4).
- Images from `ghcr.io` are built every week and scanned every day for critical vulnerabilities with Trivy. I recommend that you use these images.
- Images from `quay.io` are built on every push event and scanned for vulnerabilities with Clair.

### Features & usage
- Drop-in replacement for the [official image](https://github.com/matrix-org/synapse/tree/develop/docker).
- Unprivileged image: you should check your volumes permissions (eg `/data`), default UID/GID is 991.
- Based on [Alpine](https://alpinelinux.org/), which provides more recent packages while having less attack surface.

- Comes with a [hardened memory allocator](https://github.com/GrapheneOS/hardened_malloc), protecting against some heap-based buffer overflows.
- [Mjolnir module](https://github.com/matrix-org/mjolnir/blob/main/docs/synapse_module.md) support.
