private python packages for your team.
Keep your internal packages secure. Perfect for side projects, corporate libraries, and everything in-between.

a personal note
Hey! I'm Pierce. The one guy behind Envelope.dev.
I've been writing Python libraries for the last 6 years. I've open sourced a bunch and have an equal number just for internal use. Each time I spun up a new private library would be a headache - manually git cloning within Docker build pipelines, spinning up password protected static indexes, etc. I just needed a private pypi.
They all have the same overloaded UIs that are straight out of 2005. Most have transitioned into "security" as their differentiator and charge you handsomely for it.
I'm just trying to keep my packages private without the bells and whistles. So here we are. I built Envelope originally just to host my own packages. But it's easy enough to open up to everyone.
