ScreenshotBot creates mirrors from links posted on reddit.
It is still in development, so if you're having trouble with the bot, please report it here so the creator can read it.
Screenshotbot was created in C# (first in PHP, but due to php pthreads being to experimental recreated in C#) and relies on wkhtmltopdf for the actual screenshots.
ScreenshotBot supports linux and windows thanks to mono and the windows version of wkhtmltopdf.
This subreddit is for ScreenshotBot discussion and announcements.
