I have an old archive that I want to keep, but I cannot import it to the new one due to changes in JSON files, so I will generate a static website.
Install beloved ArchiveBox on RaspberryPi3.
Use CutyCapt inside ArchiveBox to capture screenshot of the complete website.
Use nginx and Lua module to remotely archive websites using ArchiveBox.
Install ArchiveBox an open source self-hosted web archive to preserve websites you care about.
