I made a privacy-first minimalist Backblaze▲236
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].

Sendsecurely.io – an audited secure file sharing platform▲9
Hi HN! tldr: SendSecurely is a secure platform to send sensitive documents and files to others. All files are encrypted locally before uploading to SendSecurely. The decryption keys are also encrypted and managed by a new audited database system. Anytime anyone accesses the decrypted keys, an audit log is created letting you keep track of everyone you have shared the file with and when they have accessed it. We would love for you to try this new system and share feedback! long (and technical) story: My partner and I have been working for the past 2 years on building a new privacy-oriented…
