The Tailscale source plugin for CloudQuery is now officially maintained by Tailscale — big thanks to the Tailscale team!
With the new Tailscale plugin you can now easily query Tailscale config and bring config data to your infrastructure/operational lake. This way you can have all your infrastructure data in one place and correlate between different services.
As part of its initial release, the Tailscale plugin supports pulling data for the following APIs:
Let's look at a few useful queries.


First, let's quickly look at the source configuration so the plugin. The example below syncs the tailscale_devices table to PostgreSQL, making use of the new OAuth client to authenticate.
kind: source
# Common source-plugin configuration
  name: tailscale
  path: /path/to/downloaded/plugin # Buy from here:
  registry: local
  version: 'PREMIUM'
  tables: ['tailscale_devices']
  destinations: ['postgresql']
  # Tailscale specific configuration
    client_id: 'YOUR_CLIENT_ID'
    client_secret: '${TAILSCALE_CLIENT_SECRET}'
    tailnet: ''

Example Queries

Let's look at a few useful queries we can do just with the Tailscale tables.

Unseen devices

Find all devices that weren't seen for more than 30 days:
select name, id, last_seen from tailscale_devices where last_seen < NOW() - INTERVAL '30 DAY';
tailnet    |             name              |        id         |      last_seen
---------------+-------------------------------+-------------------+--------------------- |   | 12345678082367896 | 2023-01-07 12:43:18

Key expiry disabled

Find all devices with key expiry disabled
select name, id, last_seen from tailscale_devices where key_expiry_disabled;
tailnet    |             name              |        id         |      last_seen
---------------+-------------------------------+-------------------+--------------------- |   | 12345678082367896 | 2023-01-07 12:43:18

Distribution of devices

Learn about how Tailscale client are distributed in your org across devices
select count(*), os from tailscale_devices group by os;
count |  os
   102 | macOS
   103 | linux
   70  | window

Find all devices of disabled Okta users

Other cool things once you have Tailscale configuration in your database/datalake is that you can join and query it with data from other CloudQuery source plugins.
For example, the following will show all devices of users that were deactivated on Okta:
select td.tailnet,,, td.user, td.last_seen
from tailscale_devices td
    left join okta_users ou
        on td.user = ou.profile->>'email'
where ou.stats != 'ACTIVE'


Using data from the new Tailscale source plugin you can slice and dice your Tailscale data in many ways, but the examples in this post should give you a good starting point.
