Ceryx – Open-source dynamic Nginx

In plain words

Ceryx is an open-source dynamic reverse proxy built on NGINX OpenResty that uses Lua scripting and Redis to manage configuration. It allows users to proxy requests across hundreds or thousands of microservices with instant configuration updates through an API. Designed for development teams managing containerized environments, Ceryx eliminates manual proxy configuration and enables rapid service provisioning without downtime.

Reverse proxying hundreds, or even thousands of contained micro-services is an interesting problem and one that we face daily at Sourcelair. That's why, today, we're glad to announce Ceryx, a dynamic reverse proxy using OpenResty, Lua and Flask that can be used to proxy hosts to any number of services, with it's configuration being available instantly. Ceryx is a project we've been working on the last couple of months and we're open sourcing now. In SourceLair , we're quickly provisioning dev environments and try to make web development frictionless, leveraging the power of the cloud. One of the nice goodies we provide, is a public URL for each project, that is always available and auto…from sourcelair.com

  HyperDX – open-source dev-friendly Datadog alternative2023 · github.com · ▲722

  Hi HN, Mike and Warren here! We've been building HyperDX (hyperdx.io). HyperDX allows you to easily search and correlate logs, traces, metrics (alpha), and session replays all in one place. For example, if a user reports a bug “this button doesn't work," an engineer can play back what the user was doing in their browser and trace API calls back to the backend logs for that specific request, all from a single view. Github Repo: https://github.com/hyperdxio/hyperdx Coming from an observability nerd background, with Warren being SRE #1 at his last startup and me previously…

  Novanode, Global load balancing with Caddy, no vendor lock-in2025 · ▲77

  I've been a long-time Cloudflare user, but sometimes I just want a global load balancer without the lock-in and with full configuration control (e.g., some Cloudflare rules require an enterprise plan). I love Caddy for its easy configuration, and that's why I created Novnaode. It makes it easy to launch hosted Caddy instances (with Nginx coming soon) and puts you fully in control of how to manage the configurations. No more being restricted by enterprise tiers or limited configuration options - just simple, powerful, and flexible global load balancing. Check it out here:…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
