bark-server
Bark-server is a self-hosted backend for iOS push notifications, allowing users to send custom alerts to iPhones via a REST API. It is written in Go, lightweight, and can run on Docker or as a standalone binary with minimal infrastructure requirements.

What bark-server is
A Go-based push notification service that acts as a backend for the Bark iOS app. It supports multiple deployment options (Docker, binary, or compiled from source) and can use either BoltDB for local storage or MySQL for scaled deployments. Exposes a REST API for notification routing and device management.

Best use cases
Implementation considerations
- Choose between BoltDB (file-based, zero external dependencies) and MySQL (scales to larger deployments); migration path not clearly documented.
- Plan for iOS app distribution: Bark-server is the backend; the Bark iOS app itself must be installed on target devices and configured with the server endpoint.
- Network exposure: Server listens on HTTP by default (port 8080); use a reverse proxy with TLS for production deployments.
- Data persistence: BoltDB stores data in `/data` directory; ensure proper volume mounting if using Docker, and establish a backup strategy.
- Rate limiting and authentication: Review API_V2 documentation for any built-in request throttling or API key management; role-based access control maturity unknown.
When to avoid it — and what to weigh
- You need multi-platform (Android, web) push support — Bark-server is iOS-only. If you need cross-platform notifications, a service like Firebase Cloud Messaging or Gotify would be required.
- You require guaranteed SLA or commercial support — This is a community-maintained open-source project with no formal support agreements or uptime guarantees.
- You need enterprise authentication or compliance features — Bark-server lacks built-in SAML, OAuth, RBAC, or audit logging features typically required in regulated environments (healthcare, finance, etc.).
- You cannot manage persistent storage infrastructure — Even with MySQL backend option, you are responsible for database provisioning, backups, and maintenance.
License & commercial use
Licensed under the MIT License, a permissive open-source license that permits commercial use, modification, and distribution with minimal restrictions.
MIT License allows commercial use internally and as a service layer. However, you remain responsible for compliance with Apple's App Store terms regarding the Bark iOS app distribution and APNs usage. No warranty is provided; review liability implications before production deployment.

HTTP by default; secure it behind a TLS-terminating reverse proxy in production. Inherits Apple APNs certificate security model. No built-in rate limiting, request signing, or request authentication mechanism described. API key/authentication strategy requires review of API_V2 docs. Audit logging is not mentioned. Data in transit to APNs is controlled by Apple; local data at rest depends on your environment (filesystem or MySQL encryption).
Alternatives to consider
Gotify
Open-source push notification server with web UI and cross-platform support (web, Android). More feature-rich but heavier than Bark-server; less iOS-native.
Firebase Cloud Messaging (FCM)
Managed service by Google supporting iOS, Android, and web. Eliminates self-hosting but locks you into Google ecosystem and requires cloud account.
Ntfy
Lightweight, open-source notification service with CLI and web support. Simpler than Bark but requires more custom iOS integration since it is not iOS-native.
