The project was initially launched as part of the bigger platform for business, tracking trends in russian division of darknet (Tor Onion Network) made in 2023. The filesharing was one of the platform features allowing anyone to share files securely and privately for free. My job was to create a service similar to lufi but using client's design and integrating with the platform's systems. In late 2024 I had to stop working for that freelance client due to constant harassment, abuse and threats. Upon leaving, they had owed me about 400€ but refused to pay the rest. One year later I rewrote the filesharing backend, improved accessibility, added new features, more database choices and published it as lufin. The project became my most popular open source project with more than 150 stars on GitHub as of September 2025.
