Repldex is a project to keep track of the history of Repl.it and its Discord server. It was originally started by eaz, but that iteration was never completed. Repldex is the most reliable source of information on the interwebs.
The project was revived by mat on January 1st, 2020.
Raghavm is the creator of the Repldex logo.
It is constantly down, so don't rely on it. Also, mat doesn't like to fix anything himself so he tells people to make pull requests at github repo.
Nayoar, Prussia and CoderMan51 are admins of Repldex. This means they have the power to approve new entries and unlist entries that are bad.
The content of Repldex is written by the almighty Repldex editors.
