productannouncements

Boson stores each notification, pushes in-app updates over a WebSocket, and gives your team a developer console. Your product keeps the users. Boson keeps the feed.

What ships today

  • In-app delivery is live: events are stored for the inbox and published to connected subscribers.
  • Email, SMS, and push share the same events API. They send when that channel’s provider is configured.
  • A plugin-style worker looks up a channel handler by name, so a new channel does not fork the inbox.

Start with one event

curl -X POST https://api.getboson.com/v1/events \
  -H "content-type: application/json" \
  -H "x-api-key: $BOSON_API_KEY" \
  -d '{
    "channel": "in_app",
    "subscriberId": "user_123",
    "title": "Deploy finished",
    "body": "api-7f3c is live"
  }'

Open the console, create a workspace, and send that first in-app event. The free tier is the starting offer - billing is not collected from this site yet.
