## The Hook

Noticed is a Rails gem that sends one notification to many recipients over many channels at once: email, SMS, Slack, push and in-app records your UI can show.

## What's Good

MIT (excid3/noticed), release v3.1.0 (2026-09-30), maintained since 2020. Supports both individual deliveries (each recipient gets their own notification) and bulk deliveries (for example one Slack message). Delivery methods run as background jobs, and notifications are stored as database records. ★~2.7k.

## The Catch

Rails only. Upgrading from version 1 to 2 or later required a data migration. For many channels and preferences across languages, a dedicated service like Novu may fit better.

## Verdict

The go-to notification layer for Rails apps.
