strata — what's in the archive. every app on the network writes its own kinds of records; this is how much of each there is, and when it arrived.
how to read this
each row is an app, named by the identifier its records carry — app.bsky is Bluesky, sh.tangled is Tangled. ▸ opens an app to show its record types.
columns are the archive in order, oldest on the left, in chunks of about 3 million records. the dates are when the archive received the records, not when people wrote them: in its first six days it replayed the network's whole history (history, replayed); after that each chunk is a few minutes of live traffic (as it happened).
account and identity changes belong to no app and aren't counted. everything else bundles the apps not shown.
every record an app has ever written, searched in your browser from the public archive. Bluesky is too big for this and is shown from summaries only.
the query runs in your browser only. it can read the public archive files and nothing else; nothing you type is sent anywhere.
