Open Source

Some day we hope to contribute to some meaningful open source projects but until then we have some small stuff open for anyone to stumble upon.

We put a lot of love into our Neovim configuration and have documented it via comments for others to adopt. You can find the Lua source here. We even created our very own color scheme called Shinjuku.


This website is open source with the repo located here. It is built using awesome open source technologies like Typescript, React, & Gatsby, and is hosted on Vercel.

That's not all! We welcome you to check out all our repos to see if something piques your interest.
