From the cryptic terminal commands to the innumerable ways to shoot yourself in the foot, I always struggled to use TLS certificates. I love how much easier (and cheaper) Let's Encrypt made it to get certificates, but there are still plenty of things to struggle with. That's why we built Relay: a free, browser-based tool that streamlines the ACME workflow, especially for tricky setups like homelabs. Relay acts as a secure intermediary between your ACME client and public certificate authorities like Let's Encrypt. Some ways Relay provides a better experience: - really fast, streamlined…

It works standalone too, no Kubernetes required. A Grafana dashboard is included. The new release is a major rewrite, built from experience running this across a large number of production clusters. The main pain point it addresses: at scale, with thousands of certificates, the exporter was putting too much pressure on the Kubernetes API.…

Hello! This project is a TLS/X.509 certificate manager and PKI. Designed to provision and install your TLS certificates across public and private endpoints. It's something I created for my home lab, but has quickly expanded as I have been experimenting more and more with AI development tooling. You can see the product overview: https://www.zaita.com It's architecture and usage is nicely documented: https://docs.zaita.com Unfortunately, you do need to sign up to have a play, but there is a demo instance that doesn't require a credit card. Just enter an email (I won't…
