Urbit Statistics

Take a look at the following Urbit network usage statistics. The chart below displays the daily count of active ships since June 4, 2022.

For more detailed data, feel free to select “Total Booted Ships“, “Online Ships Composition“, “Address Space Composition“, and “OS Version Distribution“. Each of these options will reveal specific insights.

We’ll go ahead and provide a breakdown of each category in the following sections.

Total Booted Ships

This chart shows the cumulative total of Urbit ships that have been online at least once since ~June 4, 2022.

Note that this statistic (and all statistics on the network explorer) do not include comets and moons. Read this article to understand how Urbit works.

Online Ships Composition

Online ships are measured using a growth accounting framework. The partitions are as following:

  • New: Online ships today that we have never seen before.
  • Resurrected: Ships that were offline yesterday day but are online again.
  • Retained: Ships that were online yesterday and also today.
  • Churned: Ships that were online yesterday but are offline now.
  • Missing: Data missing because of an incident.


  • 2023-05-05: The radar ship ran out of memory, partial data loss for the day.
  • 2023-05-14: The galaxy ~deg was misconfigured after an upgrade, leading to peer discovery problems for radar.
  • 2023-05-15: The galaxy ~dem was suffering from a regression after an upgrade, causing radar to be unable to contact stars and planets under ~dem.

Address Space Composition

Address space composition is tracked via Azimuth L1 and L2. The partitions are as follows:

  • Spawned: Cumulative number of ships spawned by date.
  • Set Networking Keys: Cumulative number of ships that have set their networking keys at least once by date.
  • Booted: Ships that have been online at least once since ~June 4, 2022.
  • Online: Cumulative number of ships online by date.

OS Version Distribution

This chart is useful for roughly measuring how well urbit-os over-the-air updates are propagating across the network.

Note that only the four most common versions are shown, the rest are aggregated under “others.”
