Isochrone.ch
Explore public transport accessibility in Switzerland
Isochrone.ch turns Swiss public transport timetables into an interactive travel-time map. Choose a starting point, departure time and time limit to see where you can go. Free, no signup, with fast routing directly in your browser.
Hey Product Hunt! 👋
I'm Aubry, a software engineer from Switzerland, and I'd love to introduce Isochrone.ch, a free interactive map for exploring public transport accessibility across Switzerland.
Most journey planners answer one question: "How do I get there?" but sometimes, the question is actually "Where can I go?".
For example:
Where could I go hiking within 90 minutes of Lausanne?
Which towns are within commuting distance of my workplace?
How does changing my departure time affect where I can travel?
With Isochrone.ch, you simply pick a starting point, choose when you want to leave and how long you're willing to travel, and the map reveals the places you can reach.
The technical twist that makes it stand out from pre-existing isochrone mapping tools: All public transport routing runs directly in your browser. No server round-trips for each calculation, making it superfast and highly interactive. I developed an open-source routing library called minotor.dev to make this possible, using optimized timetable data and implementing the RAPTOR algorithm.
I originally released Isochrone.ch in early 2025 as a personal side project. I've continued developing it since then, and I'm excited to introduce it to the Product Hunt community.
The application is completely free and doesn't require registration.
I'd love your feedback! Would you use a tool like this to plan weekend adventures, choose where to live, or explore something else entirely?
Thanks for checking it out! 🚆🗺️
