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
• 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
