Show HN: Epictopus, a Collaborative Writing Platform

I have a similar app I'm working on called Tome:

- https://tome.cfapps.io

- https://github.com/d3sandoval/tome

Mine is focused on collaborating on Poetry and other Prose. I'm currently working on implementing versioning and sharing features.

This looks like an awesome bit of competition! Is it open source?

Just FYI: https://bx1525ob52oz.landen.co/login , linked from the "Get Started" button at the bottom of the page, returns a 404.
