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.
