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.

At previous companies, I've used enterprise products for this before. They all have the same overloaded UIs that are straight out of 2005. Most have transitioned into "security" as their differentiator and charge you handsomly 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. So here's my core promise:

🤝

My core promise:

  • I'm focusing on Python. There are existing options for other languages.
  • I'm not in this to make money (I do that at my main company). Your subscription here pays for storage and a portion of server costs, that's it.
  • What you see is what you get. I'm not trying to build 100 new features and charge you for ones you don't need. Judge us by our current features and not future promises.

Let's get building. 🚀
