Streambench – Native Mac Client for Kafka and NATS

In plain words

Streambench is a native macOS desktop application for managing Kafka, Redpanda, and NATS JetStream brokers. It provides a graphical interface to browse topics, tail messages in real time, inspect consumer lag, and manage streams without relying on command-line tools. Built with a Rust broker core and optimized for Apple Silicon, it offers features like seeking by offset, sequence, or timestamp across virtualized lists. The application is designed for developers who prefer a GUI-based workflow when working with message streaming infrastructure.

From the sources

Browse topics, tail messages, inspect consumer lag, and manage JetStream streams from a local Apple Silicon desktop app with a Rust broker core.

Like TablePlus, but for streams. A local Apple Silicon desktop app with a Rust broker core. Connect to Kafka, Redpanda, or NATS JetStream brokers you already run, then browse topics, tail messages, inspect consumer lag, and manage streams from one minimalist GUI. Looking for a specific workflow? See the Kafka GUI and NATS JetStream GUI pages. Tail topics in real time or browse historical pages. Seek by offset, sequence, timestamp, or from the beginning in a virtualized list. One macOS desktop app for Kafka-compatible brokers and NATS JetStream. Topics, partitions, consumer groups, streams, consumers, and KV buckets. Per-partition committed offsets, high watermarks, and lag totals refreshed…from streambench.app

  Franz – A desktop client for Apache Kafka2024 · github.com · ▲45

  This is the source code to Franz, a native desktop client for Apache Kafka I've been working on for the past ~three years or so. Around 2021, I started using Kafka at a startup and I didn't like any of the clients that were available at the time, so I decided to build my own in my spare time[1]. I wanted a solid native experience on the Mac that wasn't web based and didn't require any Docker containers to run. A few months ago, I decided to make the code source-available[2] in part because I like the idea of my users being able to see the code they're running and in part because I want to…

  New Beautiful Desktop and Web UI/Monitoring for Apache Kafka+Kinesis2023 · kadeck.com · ▲26

  Hey folks, I'm super excited to announce the release of a new UI for Apache Kafka, Confluent, Redpanda and Kinesis that focuses on Teams and Data Mesh. (Note: the desktop version is also very popular with individual developers!) Why is this important? Because providing a solution that can be used by both IT and business (non-technical) users is essential when building applications that process business data. Of course, we are mainly developers working on Kadeck. So you won't miss any of the features you need to troubleshoot and monitor Kafka and your applications. In fact, we have put a lot…

  Talanoa▲346

  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…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
