Via @vga256@tomodori.net on Mastodon:

really, really impressed with posty: a mastodon archive -> html static site generator

it ingests your mastodon archive (post history) as a zip, and barfs out an entire static html site with indices and tags. all servable with any standard web server.

this is super helpful because when i shut down the dialup.cafe instance, there was no easy way to get access to my old posts and images.

it can either be run online here:

or instructions here for running it locally:
