+title: 📦 Content Pack - WebXDC Offline Apps
+authors: [nxf99]
+tags: [contentpack]
+---
+
+[WebXDC apps](https://webxdc.org/) are marketed as "Secure mini apps for chats". They are supported by a variety of secure messagings apps, but primarily [Delta Chat](https://delta.chat/en/). As we recently added support to ButterBox for offline communication via DeltaChat and built-in ChatMail server, we though it made sense to also have a content pack for distributing an excellent collection of offline ready apps you can run inside your groups chats.
+
+The content in this pack comes from webxdc.org and apps.testrun.org. All rights and permissions to the content are as stated on those sites and in their respective source code repositories.
