Products that do what RudderStack, open-source CDI (open-source Segment alternative) does
RudderStack (https://github.com/rudderlabs/rudder-server) is an open-source customer data infrastructure (a.k.a open-source alternative to Segment). We firstly want to thank the HN community for showing us love and support in our previous HN post (https://news.ycombinator.com/item?id=21081756). At that point, we had just open-sourced the repo and were not fully prepared for a Show HN. We wanted to share updates since then and also do our official Show HN. Updates since Sept 2019 ================= 1. Changed the name from Rudder to RudderStack :) 2. API…

GitHub: https://github.com/rudderlabs/rudder-server/ === Firstly, a big thanks to the HN community for showing us love and support in our previous HN post (https://news.ycombinator.com/item?id=21081756). At that point, we had just open-sourced the repo and were not fully prepared for a Show HN. We wanted to share updates since then and also do our official Show HN. Updates since Sept 2019 1. Changed the name from Rudder to RudderStack :) 2. API compatibility with Segment 3. Open-source control plane so no dependency on the hosted control plane for…

Dear HN, I am Riwaj, the cofounder of dstack.ai (https://github.com/dstackai). A few months ago, we built an online service that allows users to publish data visualizations from Python or R. The idea was to build a tool that did not require additional programming or front-end development for publishing data visualizations. Such a code can be invoked from either Jupyter notebook, RMarkdown, Python, or R scripts. Once the data is pushed, it can be accessed via a browser. Open-sourcing dstack: During our customer discovery phase, we realized that dstack.ai should integrate a lot…

http://ghn.cloudapp.net/ If you can, try right-clicking on an image. This page started off as a random collection of stuff I wanted to try out (spinning up an Azure linux VM included) where I gave myself "1 hour per feature" to learn new stuff. Shell scripts, command-line webkit-based png rendering, pcntl_fork, piwik... Fun stuff. I know, yet another view of HN, no biggie. I welcome all feedback and questions!

Hi everyone! I built this because I wanted a little bit more organization around my Claude sessions, worktrees and plans while staying in the terminal and not relying on another SaaS tool. Since it's a command line tool, the added bonus is that Claude can use `td` directly. The td calendar was just a fun add-on but the Claude session stats have been pretty interesting! Let me know what you think!

Hi. We just open sourced Bullet Train, a Feature Flag and Remote Config platform. It's a collection of tools: server API, admin front end and clients for a bunch of different platforms. Together they allow you to control feature flags and remote config across projects, environments and users. We realised that we were building ad-hoc feature flag stuff into individual projects over and over, so we had a look around to see if there was a way of doing this in a more formal manner. There are a few commercial solutions around but they were quite expensive and seemed to be aimed more at the…

Hi HN, I recently open sourced a small tool (Remuda) that I built at work to remove some of the friction of launching and managing agents and figured HN might be interested. I also wrote a post on the company blog that goes into more detail about why I built it and showcases its features: https://www.yendo.com/blog/remuda-an-agent-orchestrator

I built a CLI tool that turns codebases and PRs into diagrams so you can quickly understand how things fit together. Originally made it because I couldn't follow my own AI-generated repos. Just shipped a big update: - Switched from D2 to Mermaid for rendering - Tree-sitter AST parsing + agentic flow instead of raw LLM calls. ~50x faster. - Works on any GitHub repo or PR, not just local - Dropped the web frontend, it's just a CLI now - Published as a pip package Still a ton to improve and I'm building fast. Feedback, issues, PRs all welcome.

Hi everyone! My name's Christian, and I'd like to share what we've built at OrgStack - a complete data validation platform for engineering teams: https://orgstack.io It's estimated that data quality issues cost US businesses over $600 billion per year[1]. Poor data quality is difficult to detect, and even more difficult to resolve. This eats up engineering resources and leads to outages in production infrastructure. Our goal is to make it easy for data and software engineering teams to manage data sources, receive critical alerts, and trace data-related incidents to their source.…

Looking for early users: we ship same-day on feature requests and can adapt the tool to your workflow fast. Try it and let us know what’s missing. Happy to make it work for your team. Curious what HN thinks about the UX, install friction, or any must-have features before ditching the daily standup.

I built Captan (https://github.com/acossta/captan), a tiny open-source CLI tool for managing startup cap tables. Instead of juggling spreadsheets or paying for expensive SaaS cap table solutions, Captan stores everything in a simple JSON file that you can version-control in Git. It supports: - Stakeholders (founders, employees, investors) - Security classes (Common, Preferred, Option Pool) - Share issuances - Option grants with vesting schedules (monthly, cliff) - SAFEs (record + simulate conversion at a priced round) - Cap table math (Outstanding vs Fully Diluted) -…

Hi HN, I just wanted to share what I have been working on for the past few months: A firmware analyzer for embedded Linux systems that helps uncovering security issues running entirely in the browser. This is a very early Alpha. It is going to be rough around the edges. But I think it provides quite a lot of value already. So please go ahead and drop a firmware (only .tar rootfs archives for now) and try to break it :)

This is OpenDeck, my own platform for building custom MIDI controllers. I've been working on it for more than 10 years, and now I've made the biggest change so far - rewritten the entire codebase to make use of Zephyr - RTOS with which I've been working professionally for few years now. This now allows me to support many newer boards, complex features and also to modernize the codebase in general. I've been limited on all fronts before. The platform itself allows for simple building and configuring of custom MIDI controllers - main reason for that is because it requires no coding. Load the…

I've been playing with cross platform windows/linux Kubernetes clusters recently and have had endless problems with installer scripts misconfiguring networking by using the wrong NIC etc. I got frustrated with the tooling on windows to debug container networking so I built a tool that attempts to stitch together the HNS (Host Network Service) & HCS (Host Compute Service) resources into a tree that shows the relationship between configs. You can also search over it to find the networking impacting your containers or launch the windows built in packet capture tool to create a network…

Hi HN, Today I'm showcasing Trunchbull, a benchmarking platform designed for authoring benchmarks and running them against different models. We have direct support for benchmarks that use the harbor authoring system, custom tool authoring via the vercel ai sdk and configuration limits. We've also already imported terminalbench 2.0, as a sort of proof of concept that our harbor task orchestrator works, although you currently need a paid account as we are provisioning sandbox environments. I've made several popular benchmarks publicly available for testing. You dont need an account or your…

Hey HN! I wanted to share an open-source project I’ve been working on called k8sAI. It’s a personal AI Kubernetes expert that can answer questions about your cluster, suggests commands, and even executes relevant kubectl commands to help diagnose and suggest fixes to your cluster, all in the CLI! As a relative newcomer to k8s, this tool has really streamlined my workflow. I can ask questions about my cluster, k8sAI will run kubectl commands to gather info, and then answer those question. It’s also found several issues in my cluster for me - all I’ve had to do is point it in the right…

Hey everyone, I was always tired of setting up PowerDNS, Bind and PiHole and I am trying to do more projects in Rust, so here is Nomina.

PiHole AdBlocking etc. https://github.com/DatanoiseTV/Nomina

Hey any astrophysicist reading hn there? Was sick in august (yeah isn't that nice) and made a small python fits table viewer for the terminal with textual. It would be great to have people try it so if you find any issue I can improve it. If you have no FITS file but would like to try regardless there are some test file in `/test`. Ciao!
