Yunohost is a pretty interesting project, despite my approach being different and is more about using files instead of APIs for composability, kind of similar to what is described in Composability with other tools:
Files allow interoperability to emerge retroactively. New apps can come along and implement the file formats of other popular apps, uplifting their file format into a de facto protocol. This has happened many times, from .doc, to .rtf, to .psd. Competing products are able to get off the ground by interoperating with incumbents. New workflows can be created permissionlessly.
Is nice to share those different approaches about how to enable more collaboration between TW users and between TW and other tools. Thanks for the talk and ideas/tools exchange. Regarding excalidraw, I think I’m going to use tldraw plugin for TiddlyWiki:
