Serial, TCP, UDP, MQTT, WebSockets—Now in One Unified App

  1. 1DA

    Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

    Hi everyone, I recently published a small open-source project. It’s a minimal network packet analyzer written in Go — designed more like a learning toy than a replacement for Wireshark. It currently supports parsing basic protocols like TLS, DNS, and HTTP, and includes a tiny fuzzing engine to test payload responses. You can inspect raw packet content directly from the terminal. The output is colored for readability, and the code structure is kept simple and clear. The entire program is very small — just about 400 lines of Go code. I know it’s not anywhere near Wireshark’s level, and I still…

    Over the last few years, I've needed an easy way to quickly serialise and deserialise various network protocols safely and efficiently. Most of the libraries that existed at the time were either quite heavy, had less than stellar performance, or were an abstraction level above what I was looking for. I decided to put together my own class to do the job, starting with an easy, low-overhead way to move bytes in and out of arbitrary buffers. Along the way, it picked up useful bits and pieces, such as buffer structures and allocators that made the byte shuffling faster, often being able to do it…

    Hi HN! I'm Fischer, and I'm super stoked to share a project that I've been working on for a little over a year: Manta, an open-source, cross-platform, vendor-independent tool for debugging and rapid prototyping with FPGAs. This was originally my Master's Thesis at MIT, where I developed it for our course on FPGA design. We needed an alternative to vendor debugging tools, which only supported x86 machines running Windows or Linux. We were able to patch in macOS support with VMs, but as more students came bringing ARM-based devices, we needed a new tool. So I developed this. It's called Manta,…

    Hi HN! I've been working on AnuDB, a lightweight embedded key-value database written in C++ with a focus on simplicity, performance, and small footprints. It now has native MQTT support, allowing you to write directly to the database by publishing to an MQTT topic. but it’s designed to work well on embedded devices, edge nodes, and anywhere you need local persistence without spinning up a full database server. Highlights: MQTT-based data ingestion (zero setup DB writes via publish) Small and fast (single binary, no external dependencies) Append-only write-ahead log for durability Demo:…

    Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

    The Problem Enterprise Go apps typically use multiple message queues: RabbitMQ for reliability, Kafka for streaming, SQS for cloud, NATS for microservices, Redis for caching. Each has different APIs, error handling, and testing strategies. Result: Teams spend months learning 6+ SDKs instead of building features. Migration = complete rewrites. The Solution mqutils provides one unified API for 6 major message queue systems. Same code, different URL: // Switch systems by changing URL only consumer, err := mqutils.NewConsumer("amqp://localhost:5672/orders") consumer, err…

    Hi HN. I'm Carl, creator of LavinMQ. LavinMQ is an open-source message broker. AMQP 0-9-1, MQTT, HTTP and streaming. Single binary, minimal resource use. If you know RabbitMQ, it's that (but running on a fraction of hardware). We're the team behind CloudAMQP where we've hosted RabbitMQ for 14 years. Sometimes customers hit issues we couldn't fully explain / work around. So we built our own broker, in order to provide solutions where we previously couldn't (which is much easier when you control the full stack). It all started by me building an open-source AMQP proxy to handle short-lived…

    Async.MQTT5 is a professional, industrial-grade C++20 client built on Boost.Asio. This client is designed for publishing or receiving messages from an MQTT 5.0 compatible broker. Async.MQTT5 represents a comprehensive implementation of the MQTT 5.0 protocol standard, offering full support for publishing or receiving messages with QoS 0, 1, and 2. Our clear intention is to include the Async.MQTT5 library into Boost. We are actively working on it.
