Products that do what I built a free worldwide holiday and disruption tracker does
Hi HN, I’m the creator of Alarms.Global, a free tool I built while working in logistics. I was constantly juggling scattered holiday calendars and scanning local news to figure out why shipments were delayed. What it does: Tracks public holidays in 190+ countries (so you know when offices, ports, and customs are closed) Aggregates real-time transport disruptions (strikes, port congestion, weather issues, etc.) Shows everything on a filterable world map Works in 14 languages The idea was to create a single open platform to see what might stop goods from moving today. Tech: It’s built with…

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…

Hi all! I'm a 17-year old self-taught developer just starting to tap into the mobile world! :3 This summer, I've worked on a minimalist distance-based alarm clock app that wakes you up before you miss your stop! Check it out here! http://www.windowsphone.com/en-us/store/app/commuter-buddy/cb9b5107-41e0-4d2b-b0d6-110fe555fc3b Feedback and comments are welcome, thanks :)

I kept running into this: timer on my laptop, alarm on my phone, timezone / discord timestamp conversion app in a separate tab. Switching between them was a hassle and I wanted to be able to set them up and manage really fast anywhere I was. So I built Time Keep, it puts world clocks, timers, alarms, countdowns, a stopwatch, breaks, a sleep planner, Discord timestamps, and more into one always open place. Works without an account or signup. All tools are fully functional immediately. Sign in to save your data across sessions. Pro adds live cross-device sync. Shared countdown links show…

Hey HN. I made a micro site one recent evening to see upcoming (and recent past) timezone transitions. At my job, we have some timezone specific code where we often see spikes in metrics due to random timezone shifts around the world. Just for fun, I wanted a way to easily see where and what this timezone shift might have been, so built this mini site to do so. Its fully clientside and works by making use of the Internationalization API, so if you need an API for this you're coming to the wrong place, but feel free to yoink the code. Its just one fat index.html file. Served off my VPS via…

Hi HN, The two of us are working on our real time analytics service Worldlogger for two-an-a-half months now. Today we rolled out a new version. It still has some bugs here and there, but it works :) Worldlogger kind of does what Chartbeat and Getclicky are doing, but we try to mix the best from both worlds ;) Curious what you think about it! http://worldlogger.com/ Cheers E

Hi HN, I'm Fran! I'm excited to share my latest project with you all. I built an AI travel planner that generates custom travel itineraries in seconds. Whether you're planning a weekend getaway or a month-long adventure, this tool can create a detailed, professional-level plan that includes day-by-day activities, hotels, restaurants, and more. As a frequent traveler, I wanted to create something that simplifies the overwhelming task of trip planning and ensures you make the most of your time at any destination. The AI considers various factors to provide recommendations that suit your…

Hello HN, I made the web app that helps plan your routes/road trips. It has so many options that I don’t know how to explain in simple words :), so I’ll try like this. What is cool about it is that your routes are shareable and hackable. The routes come in the format ie. https://camptarget.com/London,Uk/Vienna,AT/Istanbul,TR/5h:6d, meaning we travel from London via Vienna to Istanbul, driving 5 hours daily while our total time budget would be 6 days. At given breakpoints (after 5 hours) we can explore the nearby locality in radius of some 30-40 miles, for…

Hey HN, My twin brother and I developed Wander, an event distribution hub, during our final year at a French engineering school. Wander is a real-time event distribution API for platforms aiming to enhance user experience and drive upsell opportunities. Access monetized events across Europe and seamlessly integrate them into their platform. Originally, Wander started as an app helping users discover events happening around them via an intuitive map and feed. You can still explore this experience on our website: https://wander-app.fr/explore. We’d love to hear your feedback or…

Former investigative reporter turned developer. I built a simple breaking-news monitor because tracking events across platforms is a mess now that Twitter’s unreliable. Bluesky is the backbone (a fraction of twitter, but still lots of journalists and OSINT folks), plus RSS, Telegram, Reddit, YouTube and Mastodon. Everything is one chronological feed with no algorithm, clear source labels, and lightweight activity detection when a region spikes above baseline (frequency math, not LLMs). But we do have a (hopefully non-obtrusive) AI-generated recent/post summary. Been building for a…

One station to find per day, 2 or 3 gamemodes depending on the city (if your city is not live yet, or you can't find it in the selector, try https://dailymetro.live/cityname/mode/classic ) Like https://dailymetro.live/sf/mode/classic for San Francisco Got huge traction in France, so I thought maybe you'll like it here too :) Made with Claude code but still took at least 50-100h of dev/design/taking user feedbacks ahahah Hope you like it

Hello HN! I'm excited to share my product that helps companies to track their competitors, their website updates, new features, social media activity etc. I already have the first set of early adopters (thanks to a pretty good ProductHunt launch) who're using it on the daily basis so I'm excited to remove the waiting list and share it with everyone. Cheers!

Hey folks! This is a project that I've been working in my free time for the past few months. It's a news aggregator that uses AI to select relevant articles and summarize them. The default sources are frameworks and libraries' updates, popular HN topics, and languages' subreddits threads that make past a certain threshold. You can run a local instance (needs an OpenAI key) and customize it with your own sources, and adjust the prompt as well. The resulting website can be browsed at https://dev-radar.com/ My next experiment will be with local news. I'm building some feeds with…

I built this after one too many 3 AM wake-ups due to API outages. Existing solutions felt overpriced and overcomplicated for my small-scale needs. Key features: Simple, GitHub-inspired dashboard Free tier: 5-minute checks, email alerts, 30-day retention Premium tier: 1-minute checks, SMS alerts, unlimited retention Significantly more affordable than enterprise solutions Tech stack: Next.js frontend, Node.js backend, MongoDB, Stripe for payments. This is my attempt to solve the "sleep vs. downtime" dilemma for fellow indie hackers. I'd appreciate any feedback or feature suggestions. What's…

Hello! For the last year I've been working on a side project, a booking management system. Among others, it allows anyone who owns a business that accepts bookings to manage them, to communicate with customers, to easily create a personalized website or to embed a calendar widget on any existing website. Link: https://www.planorio.com There is still a long way to go, but I feel that now it is ready for some very direct feedback. :) It mainly consists of an Angular frontend, a backend written in Node.js and some small tools written in PHP and Kotlin. I also created a hybrid mobile…
