New Caldera
The open-source social networks of GitHub and Obsidian
Introduction
Caldera is a rather imaginative little project: after logging in through GitHub, each of your repositories will represent a building within a city; the individual projects correspond to neighborhoods, and all the users on the platform are “living” within this virtual map. Friendships, in turn, serve as the interconnected highways that link these different elements together. Once you install the Obsidian plugin, your notes library can even be transformed into a “live” personal homepage.
It aims to allow developers and writers to recognize each other based on what they have actually done or written, rather than their titles. It is free and open-source, and by default, the content within Obsidian remains private; it will not leave your local device without your consent.
Strictly speaking, it doesn’t qualify as an AI tool; rather, it’s more like a community-friendly resource for independent developers and knowledge management enthusiasts. Those who enjoy exploring others’ code projects might find it interesting to check out.
