The NINA project started in 2020 as a community initiative to preserve messaging services at risk of disappearing. Developed mainly in Python and C++, the system operates on a distributed server infrastructure. The team maintains a focus on historical accuracy, seeking to replicate not only the functionality but also the peculiarities of each supported client version.
