## What it is
Skor is a small C utility that listens to PostgreSQL LISTEN/NOTIFY events via triggers and forwards row changes (INSERT/UPDATE/DELETE) as JSON payloads to a configured webhook. It has been superseded and folded into the Hasura GraphQL Engine, which offers reliable, scalable event delivery.

## Use cases
- send postgres row changes to a webhook as json
- trigger external actions when a database table row changes
- forward database change events to kafka or amqp
- lightweight change data capture for postgres
- notify microservices on insert update delete events

## When to choose
- you need a tiny, lightweight postgres-to-webhook notifier without extra infrastructure
- you already run a simple setup and can tolerate no-retry, no-capture-while-down semantics

## When to avoid
- you need guaranteed at-least-once delivery or retries
- you need events captured while the listener is down
- starting a new project - use Hasura GraphQL Engine instead

## Facets
- artifact type: service
- maturity: maintenance
- function: webhook, message-queue, database, http-client
- domain: databases, backend
- platform: self-hosted
- tags: postgres-listen-notify, change-data-capture, event-driven, deprecated, hasura, automation, docker, linux
