Publish and subscribe to messages
Ephemeral messaging service
# Stream Service
Send messages to a stream and broadcast to multiple subscribers. Group by topic
and rapidly blast fire-and-forget messages to anyone listening.
The stream service provides ephemeral message streams for building chat applications,
feeds and timelines. Simply send messages to a channel and know they'll expire
after 24 hours. Streams are limited to 1000 messages and 1000 streams in total.
Max message size is 512 characters.
Messages with links are automatically populated with metadata related to site.
