TransitLens
Browser-based GTFS viewer for routes, stops & schedules
What it does
TransitLens is a browser-based GTFS viewer — no installation, no account required. Drop in a GTFS ZIP or paste a feed URL and instantly see all routes and stops on an interactive map, filter by route, agency, or transport type, click stops to inspect metadata, and explore schedules and service calendars. Supports GeoJSON and KML overlays for spatial and coverage analysis. Built for transit developers, GTFS engineers, planners, and agencies.

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…

This nifty tool plots the traceroute results and shows you the RTT as well as the distance travelled by the packets! Supports MTR, flyingroutes and of course, traceroute. The existing solutions were too limited so I made that. Let me know if you have any feedback

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
