1. Caddy

   1 432 62,231 9.4 Go

   Fast and extensible multi-platform HTTP/1-2-3 web server with automatic HTTPS

   

   Project mention: An Introduction to Cosmo Router — Blazingly Fast Open-Source Federation V1/V2 Gateway | dev.to | 2025-03-10

   This approach offers a level of customizability similar to what xcaddy does for the Caddy server, eliminating the complexities associated with writing Rhai scripts to customize a precompiled binary, as is the case with the Apollo Router.

3. traefik

   2 194 53,645 9.6 Go

   The Cloud Native Application Proxy

   

   Project mention: Cloudflare is almost perfect | dev.to | 2025-01-16

   Sidecar containers: Google Cloud Run has a cool feature where you can run multiple containers next to each other. So for example, if you want to run Caddy or Traefik as a reverse proxy for your ingress container and then have both your web frontend container & backend api container co-located in the same service, you can do that & have everything be super low latency.

4. minio

   3 112 50,773 9.8 Go

   MinIO is a high-performance, S3 compatible object store, open sourced under GNU AGPLv3 license.

   

   Project mention: Show HN: Open Rewind – POC for audio and screen and video streaming to S3 | news.ycombinator.com | 2025-01-04

   I havent tried yet, but I think we can use https://github.com/minio/minio for this.

5. etcd

   4 78 48,636 9.9 Go

   Distributed reliable key-value store for the most critical data of a distributed system

   

   Project mention: I Stopped Using Kubernetes. Our DevOps Team Is Happier Than | news.ycombinator.com | 2024-11-27

   > stale bot marked this as completed (by fucking closing it)

   Ah, yes, what would a Kubernetes-adjacent project be without a fucking stale bot to close issues willy nilly

6. Vault

   5 176 31,960 9.9 Go

   A tool for secrets management, encryption as a service, and privileged access management

   

   Project mention: OAuth2 for System-to-System Authentication: A Deep Dive into the Client Credentials Flow | dev.to | 2025-02-18

7. consul

   6 63 28,782 9.5 Go

   Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.

   

   Project mention: Why We Chose NGINX + HashiStack Over Kubernetes for Our Service Discovery Needs | dev.to | 2024-10-06

   No need for NGINX reloads: Since NGINX queries the Consul Go API client for healthy services on each request, there’s no need to reload NGINX whenever a service moves between nodes or when new instances are added.

8. nsq

   7 15 25,152 4.2 Go

   A realtime distributed messaging platform

   

   Project mention: RabbitMQ 4.0 Released | news.ycombinator.com | 2024-09-18

   https://nsq.io/ is also very reliable, stable, lightweight, and easy to use.

15. flipt

    13 21 4,087 9.8 Go

    Project mention: OpenFeature – a vendor-agnostic, community-driven API for feature flagging | news.ycombinator.com | 2024-10-25

    Speaking as an open-source feature flag 'vendor' (https://github.com/flipt-io/flipt), the OpenFeature organization has been a joy to work with. They are very welcoming of new contributors (e.g., implementing a provider SDK in a new language).

    If you're interested in this space I'd recommend lurking in their CNCF Slack Channel https://cloud-native.slack.com/archives/C0344AANLA1

16. wish

    14 30 3,912 9.1 Go

    Make SSH apps, just like that! 💫

    

    Project mention: Show HN: Keypub.sh – OAuth for the terminal using SSH keys | news.ycombinator.com | 2024-12-23

    Sounds like a similar family of problems to [Wish](https://github.com/charmbracelet/wish) by charm.sh. They've been pushing this curious paradigm of "ssh apps", where ssh keys are used to automatically create identities for small self-hosted CLI/TUI apps.

    As a useful comment for messh, it looks like you've committed the ssh_server binary file to git; you may want to add that to gitignore, as binary file handling isn't a traditional git strength. I _think_ it's better than it was a decade ago when I last investigated this, but I can see that Pro Git still recommends explicitly setting gitattributes to mark a file as binary https://git-scm.com/book/en/v2/Customizing-Git-Git-Attribute...

17. devd

    15 11 3,449 0.0 Go

    A local webserver for developers

    

    Project mention: Show HN: Wd-40, a static webserver with automatic hot-reloads | news.ycombinator.com | 2024-08-18

    Someone above recommended devd, and it looks pretty nice. https://github.com/cortesi/devd

18. algernon

    16 2 2,880 9.4 Go

    A self-contained little web server that supports Lua, HTTP/3, PostgreSQL and all sorts of different things:

    A snappy and configuration-free little editor/IDE for the terminal:

    https://github.com/xyproto/orbiton

    Also a game, a book and an album, but those are unreleased long-term projects.
