    Creator here. I was looking for something as simple as Backblaze Personal [1] but privacy focused and open source. This is my attempt to build that. Uses PyQt6 [2] for the GUI and Pyinstaller [3] for creating the platform specific binaries. The backup engine under the hood is Restic [4]. The server code is written in Laravel [5]. All the code is on GitHub [6]. I actually really like Backblaze (even use B2 for this offering behind the scenes) so this isn't meant to throw shade their way. Just wanted a private open source alternative. Something like Bitwarden but for backups. [1]…

    Hi Hacker News! Shahar and Tal from Keep here. We're thrilled to announce that we're open-sourcing our alerting CLI tool, Keep (https://github.com/keephq/keep). Designed by developers for developers, Keep streamlines and simplifies alerting, making it a first-class citizen within the development process. Think of Keep as Prometheus Alertmanager but for all observability tools, with a simple and intuitive (GitHub actions-like) syntax. We believe that alerting has historically been neglected in existing monitoring platforms, leading to subpar alerting practices. With Keep,…

    Hi HN, I built Cloudstic (https://github.com/Cloudstic/cli), an open-source Go CLI that creates encrypted, deduplicated, point-in-time backups of your Google Drive, OneDrive, and local files. The Problem Google Drive and OneDrive are sync tools, not backup tools. If you accidentally delete a folder, it’s gone everywhere. If ransomware encrypts your local files, the "mistake" propagates to the cloud immediately. There is no easy way to say: "Restore my entire Drive exactly as it looked on January 15th." Why not just use Restic or Borg? I’m a huge fan of Restic, and…
