small follow-up to v0.6.0. last release shipped channel persistence; this one is mostly hardening that layer based on what shook out in real use.

hi again! i'm back with a new release of Narwhal, the lightweight message broker for edge apps i shared a while ago. the headline change in v0.6.0 is channel persistence: channels and their message history can now be durably stored on disk, so subscribers can replay missed messages after reconnecting. also swapped the async runtime from monoio to compio (still io_uring on Linux), and added first-class Prometheus metrics.

hi again! i'm back with a new release of Narwhal, the lightweight pub/sub server i shared a while ago. the biggest change in v0.5.0 is the migration from tokio to monoio as the primary async runtime, which means the server now runs entirely on io_uring on Linux.

Show HN: An extensible pub/sub messaging server for edge applications

ortuman — Wed, 28 Jan 2026 13:59:06 +0000

hi there! i’ve been working on a project called Narwhal, and I wanted to share it with the community to get some valuable feedback.

what is it? Narwhal is a lightweight Pub/Sub server and protocol designed specifically for edge applications. while there are great tools out there like NATS or MQTT, i wanted to build something that prioritizes customization and extensibility. my goal was to create a system where developers can easily adapt the routing logic or message handling pipeline to fit specific edge use cases, without fighting the server's defaults.

why Rust? i chose Rust because i needed a low memory footprint to run efficiently on edge devices (like Raspberry Pis or small gateways), and also because I have a personal vendetta against Garbage Collection pauses. :)

current status: it is currently in Alpha. it works for basic pub/sub patterns, but I’d like to start working on persistence support soon (so messages survive restarts or network partitions).

i’d love for you to take a look at the code! i’m particularly interested in all kind of feedback regarding any improvements i may have overlooked.

I'm working on Narwhal, a pub/sub protocol and server specifically designed for edge applications. The protocol can be extended via an external component, and the product is completely free and open source: https://github.com/narwhal-io/narwhal
