pushdeer

pushdeer is a lightweight, self-hostable push notification system designed to make it easy for individuals and small services to send messages to their own devices. It consists of a server component with a simple HTTP API, a client app for receiving notifications, and optional web/admin front ends for managing keys and devices. The design favors minimal setup and free deployment options so you can run it on inexpensive infrastructure or serverless platforms. Messages can include plain text and basic rich content, making it useful for alerts, build notifications, IoT signals, and personal automations. Because it’s open source, you retain control over data and keys instead of relying on third-party gateways. It’s a practical alternative to proprietary push services when you want independence, privacy, and straightforward integrations.
