Kafma – a desktop Kafka GUI client for debugging

What it does

Kafma is a desktop IDE for Kafka built around one idea: a topic is a tab. Consume and produce in one workspace, inspect schemas and lag, and replay any message to another topic. Data Clone copies a production topic — its config, schemas, and a slice of real data masked by your rules — to a local cluster, so you can reproduce bugs without modifying the source. Kafma connects directly from your device: no app account, no data proxy, no analytics or telemetry. For macOS, Windows, and Linux.

Kafma is a Kafka GUI client tool and desktop IDE for macOS, Windows, and Linux. Debug fast, close the gap between prod and dev. Intuitive. Simple. Elegant.

A desktop Kafka GUI client that simplifies how you debug Kafka. Intuitive. Simple. Elegant. Send manually or on a random loop from below, tail the live stream above — one tab, no context switch. Avro and Protobuf decode automatically. Replay, forward, or export any message — one right-click. Drafts diff against live automatically. Mock a payload from any subject, or Lab-test one to check it fits — then publish. Clone whole topics between clusters, schemas and all. Move a slice of prod into local Docker — the source stays read-only. Track lag by group and topic. Watch consumed and pending messages — without joining the group. Topics, cluster authentication, Kafka Connect, and Activity Logs —…from kafma.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…

  Kasama – an IntelliJ plugin to keep track of your coding practices2024 · plugins.jetbrains.com · ▲105

  Hi HN, I want to share with you an IntelliJ plugin I have developed and launched. Based on my own needs, I wanted a plugin that monitors my coding practices and gives me stats about them in order for me to improve on them. So, here is Kasama: An IDE plugin that works like a sport fitness tracker, gathering data on: - your coding sessions, i.e. how long are you active in the IDE and for which project - your activity in different modules, and how the activity is split between test code and prod code - your version control (git) interactions: how often you commit, the lifespan your branches,…

  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…
