RudderStack, open-source CDI (a.k.a. open-source Segment)

In plain words

RudderStack is an open-source customer data platform that collects and routes customer event data to various destinations. It offers API compatibility with Segment and includes an open-source control plane, eliminating dependency on hosted services. The platform supports approximately 30 integrations in both cloud and device modes, and can be deployed via Docker, Kubernetes, Terraform, or native installation. It is designed for teams seeking a self-hosted alternative to proprietary CDP solutions.

  RudderStack, open-source CDI (open-source Segment alternative)2020 · ▲12

  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…

  Warp, a Rust-based terminal2022 · warp.dev · ▲946

  Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…

  Is Hormuz open yet?Apr 2026 · ishormuzopenyet.com · ▲484

  I built this because I was interested in the data. Didn't fully get it to what I wanted, but thought I'd share it nonetheless. Maybe someone has better data sources they could share! Turns out live ship tracking APIs are expensive so I manually just copied the json from https://www.marinetraffic.com/en/ais/home/centerx:57.4/cente... I'll probably have an ai agent do the same thing on some cron interval, if this gets any fanfare. To actually know if the port is open without live ship tracking I found…

  I built a real-time OSINT dashboard pulling 15 live global feedsMar 2026 · github.com · ▲312

  Sup HN, So I got tired of bouncing between Flightradar, MarineTraffic, and Twitter every time something kicked off globally, so I wrote a dashboard to aggregate it all locally. It’s called Shadowbroker. I’ll admit I leaned way too hard into the "movie hacker" aesthetic for the UI, but the actual pipeline underneath is real. It pulls commercial/military ADS-B, the AIS WebSocket stream (about 25,000+ ships), N2YO satellite telemetry, and GDELT conflict data into a single MapLibre instance. Getting this to run without melting my browser was the hardest part. I'm running this on a laptop…

  Talanoa▲345

  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…
