Carpathian Open Source
The tools we use, free for everyone else.
Most of the software in our lives is built to charge us for things that shouldn't cost money. We can't fix that for the whole industry, but we can stop adding to it. So when we build something useful, we put it on GitHub for free.
A note from the founder
Free art, free software, same instinct.
Before I built software for a living, I spent years as a creative and design artist. I made paintings, prints, and visual work that I gave away. Not because the work was worth less, but because the value of art was never supposed to be the only reason it existed.
Open source is the same instinct, just in a different medium. So much of what gets called software today exists to extract money from people who depend on it. Subscriptions on top of subscriptions, and paywalls in front of features that should have been included.
We cannot do much to change how the broader software industry operates, but we can put the tools we build where anyone can use them without paying, signing up, or being sold something on the way out. If it helps you, take it. If you want to make it better, the code is on GitHub.
Samuel Malkasian, Founder of Carpathian
Why we open source
Some software does not need to be a product.
We open source the tools we wished existed when we needed them, and the ones we use ourselves every day. Every project on this page started as a problem we had at Carpathian, and we opened it because there was no good reason to lock it behind a paywall.
No accounts or upsells
We develop software that's free to clone, use, fork, and ship inside whatever you're building, and the entire working tool lives in a public GitHub repo from the moment we publish it.
Yours. Truly.
MIT licensed and on GitHub. Fork it, change it, ship it inside your own product, sell what you build with it. We are not interested in source-available pseudo-licensing dressed up as open source.
Maintained, by us.
These projects are part of our daily work at Carpathian, so the same engineers using them are the ones pushing updates, reviewing pull requests, and answering issues.
The projects
What we've shipped so far.
As we build new tools, they show up here, available for you to use, fork, or contribute to.

Pick a template, fill in your details, copy, paste into Gmail or Outlook. There is no account to make and no upsell at the end. The whole tool runs in your browser.
Carpathian WG VPN
MITLightweight WireGuard client for systems the official app doesn't reach.
A small Python utility and terminal UI that wraps the WireGuard tools on macOS and Windows. Drop a config in, pick it from a list, connect. Built for machines that can't run the official client.
The world has enough software designed to charge you. We are interested in the rest.
