kinto-changes shows the list of collection timestamps, allowing to poll changes on several collections with one HTTP request.

pip install kinto-changes

In the Kinto settings:

The list of timestamps is available at GET /v1/buckets/monitor/collections/changes/records.

The changes entries will have a host attribute, that can be used to distinguish changes from several Kinto instances.

By default, it will rely on the global setting kinto.http_host.
