Gotify

Gotify is a lightweight, self‑hosted messaging hub that exposes a RESTful API for pushing notifications and a WebSocket endpoint for real‑time consumption. Built in Go, it compiles to any platform and ships with a Docker image, making it straightforward to deploy in container‑centric environments. The server manages its own authentication realm—users, clients, and applications are all stored in a relational database (SQLite by default, with PostgreSQL support), allowing fine‑grained access control and token‑based API usage.

• REST & WebSocket APIs – Push messages via HTTP POST and receive them instantly over a persistent WebSocket connection.
• Multi‑tenant user model – Separate users, clients (e.g., web or mobile apps), and applications (message scopes) with role‑based permissions.
• Plugin architecture – Extend core functionality by writing Go plugins that hook into request/response pipelines, authentication, or message handling.
• Web UI & CLI – A single‑page React UI for administration and a gotify/cli tool for quick message pushes.
• Cross‑platform Android client – Push notifications on mobile devices via a dedicated app.

• Programmatic API – Full CRUD on messages, users, and applications; query parameters for filtering by priority or time.
• WebSocket subscription – Receive JSON payloads with metadata (title, priority, image URL) in real time.
• Webhook support – Configure outgoing HTTP callbacks for message events, enabling integration with external services.
• Extensibility – Write Go plugins that implement interfaces for authentication, message validation, or custom routing.
• CLI – gotify-cli can be scripted to send alerts from CI pipelines or local scripts.

• Self‑hosting – A single binary plus optional database; no external dependencies beyond Go runtime.
• Scalability – Horizontal scaling is achieved by running multiple server instances behind a load balancer; WebSocket sessions are sticky or session‑aware via shared Redis (optional).
• High availability – Persisted data in PostgreSQL allows database clustering; the server itself is stateless except for WebSocket connections.
• Container support – Docker images are automatically built on every release; Helm charts available for Kubernetes deployments.
• Resource footprint – Under 20 MB binary, <10 MiB RAM on startup; ideal for edge devices or small servers.

• Plugins – Drop a .so file into the plugins directory; Gotify loads it at boot. Plugins can modify request headers, validate payloads, or inject custom logic into the message pipeline.
• Webhooks – Register external URLs to receive POST requests when a new message arrives, facilitating integrations with Slack, Teams, or custom dashboards.
• Custom UI – The front‑end is open source; developers can fork and modify the React codebase to fit their branding or add new features.
• SDKs – Although not bundled, community‑written Go, Python, and JavaScript clients exist on GitHub.

• Configuration – YAML/JSON config files expose all tunable parameters (port, TLS certs, database DSN).
• Documentation – Comprehensive docs at gotify.net/docs cover API spec, plugin development, and deployment guides.
• Community – Active GitHub discussions, Matrix channel (#gotify:matrix.org), and a permissive MIT license encourage contributions.
• Testing – Extensive unit and end‑to‑end tests run on every push; code quality is verified by static analyzers.

• Zero‑cost, self‑hosted – No vendor lock‑in; MIT license removes licensing headaches.
• Real‑time delivery – Web
