During a recent subway outage in San Francisco I decided to build a webapp in the spirit of "Do I Need an Umbrella," basically to answer the question "Should I take the subway or a bus?" In the interest of learning new tools I decided to vibe code it as much as possible. First, I had Claude Code write a background script to download images of the real-time circuit diagram of the subway, which are publicly available here: http://sfmunicentral.com/ Next I had it build an image labeler tool in tkinter, which turned out to need a lot of manual tweaking before I could even get to…

Hello HN! As a long term NYC resident, I have read countless articles on ideas tweaking subway services, but always found them hard to follow without visual aid. So over the long weekend I decided to build one. It has all the basic features: trains would spawn at their origin, stop at stations, and slow down if it gets too close to another. You can also design custom routes by piecing tracks together. Have fun, and let me know what you think!

This was something I built while trying to look for housing in Toronto that was decently transit-accessible to my office while still cheap. The backend is written in Rust. It parses public GTFS data from transit agencies and performs a simple heuristics-based BFS on the bus lines to calculate how long to reach all points in a city. The frontend uses React and Mapbox GL to render each individual road segment based on how long it takes to reach. This project was a great excuse to learn Rust, deployments, and mapping. The source code is here if you are interested:…

Hello, I was running around Germany, hectically navigating public transportation, and getting lost all the time. I noticed that every station had i platforms, each used lists of n buses (trains, whatever) arriving, each has their list of m destinations. That means I would be scanning i x n x m items just to see if I was at the correct stop. As I was nervous, for every bus that arrived, I would rescan the list of stops to double check. I began thinking how I could make a better system. Linked is a very shoddy mockup of how bloom filters could be used to allow passengers O(1) lookup time for…

Hey all! My train the other day was delayed and I got curious where they all were at any given time, so I built a map and figured I'd share it.

Hi HN! I’m Alex from Parabola (https://parabola.io). Parabola is a visual programming tool for creating functional data flows that everyone can use. It’s entirely drag-and-drop, handles data sizes much larger than a traditional spreadsheet, calculates everything live, and can run your flows on a schedule of your choosing. I used to work in strategy consulting, doing data analytics for SMBs and Fortune 500 companies. The amount of time wasted on menial tasks was astounding. Things like cleaning data, generating custom reports, creating human workflows to solve shortcomings in third…

For the past few months, I've been working on a website that answers two different questions: - Where in my city have the best travel times to all the things and people I care about? - Given a listing, how far is it from all the things and people I care about? Personally this was fueled by my own frustrations when I was apartment hunting in NYC. I was frustrating to have to juggle so many Google Maps tabs when I was evaluating a listing, and it was also annoying to not have full confidence that I was even searching in the right places. I wanted to be close to work, a Trader Joe's, and a…

I previously made a web version of The Weekendest, but when I was laid off from my last job, I decided to take the free time I had to pick up Swift UI, and made a native iOS version of it. The main draw of the app is that the map is dynamically generated based on the current subway routing, so when you open the app on weekends or overnight, you'll see lines correspond to where the trains are actually running, which is a very unique NYC problem. Let me know what you think!

I made a public transport route planning program that's capable of planning journeys across Europe or North America! There's only one other FOSS project I know of (MOTIS/Transitous) that can do transit routing at this scale, and in the testing I've performed mine is about 50x faster. I've spent a few weeks on this project now and it's getting to the point where I can show it off, but the API responses need a lot of work before they're usable for any downstream application. Example query (Berlin to Barcelona):…

Hi HN, I’m a junior developer. I wanted to share a side project I’ve been working on. The national railway carrier (BDZ) has no public API. They have an official map but the UI is quite dated, often lags, and doesn't show the full route context. I wrote a short write-up about the process here: https://www.pavlinbg.com/posts/bg-train-tracker I know it's still rough around the edges (I'm still working on it), but I’d love to hear your feedback or suggestions!

I was developing/selling this application under Roadometry, but sales are getting slow and I'd prefer to make it available for free. This is a desktop Windows application which can be used for counting road traffic. https://roadometry.com https://www.youtube.com/@roadometry2011 The application uses Multiple Hypothesis Tracking (MHT) combined with Darknet Yolo. I trained the network myself. I have a tool-chain for building a video-based training set including associations, but it's quite complex to use. I never ended up training a network to perform association,…

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

I was walking around New York last month during some light rain and noticed about half the people had umbrellas open. When the rain picked up a few minutes later, that number jumped closer to 80%. It got me thinking it'd be cool to track this somehow, so I built a website! I am taking a sidewalk livestream, feeding it into a YOLO model for people tracking, then sending a frame of each detected person to Gemini 2.0 Flash, which returns structured JSON about each person's clothing and if they're holding an umbrella. I also had fun making the site look like a TV weather channel. I showed some…

Hey HN OpenCopilot is an OSS framework which helps devs to build open-source AI Copilots that actually work and embed into their product with ease. Why another LLM framework? Twitter is full of impressive LLM applications but once you peel off the curtains it’s clear that they are just demos. The reason being because building an AI Copilot that goes beyond a Twitter demo can be complex, time-consuming and unreliable. Our team has been in the AI space since 2018 and built numerous LLM apps & copilots. While doing that, we got approached by many startups saying they’d also like to build a…

Tokyo Trains▲13Semi inspired by the 3d Shinjuku station that was posted again recently, I noticed it was missing a large portion of the "complex" where "complex" is defined loosly has how far you can walk without stepping outside. So I asked Claude to make a 3d map of all Tokyo Trains, no libraries, and let you zoom into stations, and the first version with both map and the Shinjuku complex was ready in about 3 hours. It spent another 7 or so in various nit picky things I asked for to get to the current version. I know these will only get better but I think the thing I find most interesting is no libraries…

Hey HN, I built Commuter because I was tired of switching between different apps to check arrival times for BART, Caltrain, Muni, ferries, and more. This app pulls directly from the official 511 API and aims to provide a fast, clean experience focused on real-time departures. There’s no account creation, it’s free to use, and it supports every major transit provider in the Bay Area—from Napa down to San Jose. You can search, favorite lines/stops, and see live countdowns with minimal friction. It’s built entirely in SwiftUI using native Apple frameworks. Happy to answer questions about…

Hello! I built a map that generates a heatmap of the most convenient meeting spots between several people, based on public transit travel times. Move the markers anywhere in the map; all cities with sufficient transit data are supported!
