Gotify vs OneSignal

Gotify is free, open-source software for sending and receiving messages through a self-hosted server. The server includes a WebUI for managing users, clients, and applications. Messages can be sent through a REST API and received over a WebSocket connection; each includes content, a title, creation date, application ID, and priority. Priority can affect how clients present a message, including whether the Android app plays a notification sound. The Android client subscribes to the server’s message stream and displays push notifications. Optional plugins can add webhook reception, feed polling, WebUI extensions, or alarm notifications, but plugins are currently supported only on Linux and macOS due to a Go limitation. Gotify supports OpenID Connect single sign-on when the identity provider supports PKCE, as well as TLS configuration, secure session cookies, and bcrypt password hashing. Sensitive actions require session elevation. The server can run in Docker or from a platform-specific binary; Docker images support amd64, i386, arm64, armv7, and riscv64. An optional command-line client can push messages, though any HTTP client can do so. Its listed plan is free.
