+# Other projects related to Jamulus
+
+This document lists a number of third-party projects related to Jamulus, which users may find interesting.
+
+## jamulus-php
+
+[jamulus-php](https://github.com/softins/jamulus-php) implements a simplified Jamulus client in a
+PHP web server, which knows enough Jamulus protocol to fetch the list of registered servers from a
+directory, and a list of active clients from each registered server. It returns the results in JSON
+for display by a front end, such as [Jamulus Explorer](https://explorer.jamulus.io)
+or [Jamulus Live](https://jamulus.live/).
+
+## jamulus-web
+
+[jamulus-web](https://github.com/softins/jamulus-web) implments the front end used by
+the [Jamulus Explorer](https://explorer.jamulus.io) web site, which allows a web
+browser to be used to view the public server directories and the servers that are
+registered to them.
+
+## jamulus-wireshark
+
+[jamulus-wireshark](https://github.com/softins/jamulus-wireshark) is a protocol dissector
+plugin for Wireshark, to enable Wireshark to understand the structure of the Jamulus protocol
+and display it in a user-friendly way. It is implemented in LUA.
+
+## jamulus-historytool
+
+[jamulus-historytool](https://github.com/pljones/jamulus-historytool) comprises two scripts:
+* A PHP script to parse the Jamulus log file and emit it as a JSON response
+* A JS script to parse the JSON response and emit an SVG DOM node
+
+This replaces the History Graph that used to be part of the Jamulus server itself.
+
+## jamulus-jamexporter
+
+[jamulus-jamexporter](https://github.com/pljones/jamulus-jamexporter) comprises two scripts:
+* A bash script to monitor the Jamulus recording base directory for new recordings
+* A bash script to apply some judicious rules and compression before uploading the recordings offsite
+
+## jamulus-docker
+
+[jamulus-docker](https://github.com/grundic/jamulus-docker) is an implementation of Jamulus
+within a Docker container. It provides a `Dockerfile` and some documentation.
+
+## jamulus-server-remote
+
+[jamulus-server-remote](https://github.com/vdellamea/jamulus-server-remote) provides a lightweight
+web front-end for a headless Jamulus server running on Linux. It allows a user to start and stop recordings,
+and to zip them up and download them via a web browser. It is implemented in PHP.
