Well done

 

Very nice.   Glitch I cannot reach the top left menu, it’s always out or reach 
even if I shrink the view to on my browser.

 

The map does not include bridges, webtunnels, which I suppose on their own do 
not contribute to “bandwidth”

Subject: [tor-relays] RouteFluxMap: open-source Tor relay map with historical 
bandwidth snapshots

 

Hello tor-relays,

I’m sharing a new open-source visualization tool for exploring Tor relay 
distribution and bandwidth over time (updated daily):

*       Live site: https://routefluxmap.1aeo.com 
<https://routefluxmap.1aeo.com/> 
*       Open-source code: https://github.com/1aeo/routefluxmap

What it does:

*       Interactive world map of Tor relays, with relay presence and density 
visualized using bandwidth-weighted aggregation
*       Flow-style visualization based on the probability of traffic per relay, 
derived from each relay’s advertised bandwidth and consensus weight (not 
traffic tracing)
*       Historical snapshots built from Tor Collector / Onionoo data, covering 
2007 through present
*       Country-level summaries showing relay count and aggregate bandwidth

Why this is useful for relay operators:

*       Provides a fast, high-level view of where Tor bandwidth is concentrated 
geographically
*       Helps identify broad shifts in relay distribution or bandwidth that may 
correlate with performance or reachability changes
*       Useful for gaining network-wide context when debugging issues that 
aren’t obvious from single-relay metrics alone

Implementation notes:

*       Static frontend built with Astro + React using Deck.gl and MapLibre
*       Data pipeline aggregates publicly available Tor network metadata into 
versioned historical snapshots

Feedback is welcome, particularly on which additional historical or aggregate 
views would be most useful for operators.

Significant inspiration and guidance from an open source and 7 year previously 
retired effort, TorFlow: https://github.com/unchartedsoftware/torflow
