PufferPanel

PufferPanel is a web‑based game server management system that consolidates the administration of multiple game servers into a single, unified interface. From a technical standpoint it exposes a RESTful API for server lifecycle operations (start, stop, restart, delete), configuration management, and real‑time log streaming. The core of the application is written in Go (Golang), chosen for its compiled performance, native concurrency primitives, and cross‑platform binaries. The front‑end is a single‑page application built with Vue.js and Vuetify, communicating with the Go backend over HTTPS using JSON payloads. Persisted data resides in a PostgreSQL database, while optional Redis can be leveraged for caching and pub/sub during log streaming.

Architecture

• Backend: Go 1.20+, utilizing the net/http standard library with a minimal router (chi). Authentication is JWT‑based, and role‑based access control (RBAC) is enforced through middleware. The Go service talks to game servers via SSH or a custom binary agent that listens on a TCP port, enabling remote command execution and file operations.
• Frontend: Vue 3 + Vuetify, built with Vite. The SPA consumes the API and renders dynamic dashboards for each server instance.
• Database: PostgreSQL 13+, used for user accounts, server definitions, and audit logs. Schema migrations are handled by golang-migrate.
• Optional Components: Redis for in‑memory caching of active server states; Docker Compose can spin up the stack with a single command, making it easy to run in development or production.

Core Capabilities

• Multi‑Server Management: Create, clone, and delete server instances for a variety of game engines (Minecraft, Source Dedicated, PocketMine, etc.).
• API Access: Exposes endpoints for CRUD operations on servers, users, and permissions; supports webhooks to notify external services of state changes.
• Plugin System: Developers can write Go plugins that hook into lifecycle events (e.g., OnStart, OnStop) or extend the API with new endpoints. Plugins are loaded at runtime from a designated directory.
• Real‑Time Logs: Implements Server-Sent Events (SSE) for streaming logs to the UI, allowing developers to monitor server output without polling.
• Scheduling: Built‑in cron‑like scheduler for automated tasks such as backups or restarts.

Deployment & Infrastructure

PufferPanel is designed to be self‑hosted on any Linux distribution with Docker support. The official container image is Alpine‑based, keeping the footprint small (≈ 70 MB). For high availability, multiple instances can be load‑balanced behind a reverse proxy (NGINX/Traefik) with shared PostgreSQL and Redis instances. The application scales horizontally by simply adding more API nodes; state is persisted in the database, and logs are streamed through Redis pub/sub. The Go binary also supports running as a systemd service, providing easy integration with traditional Linux deployment workflows.

Integration & Extensibility

• Webhooks: Register endpoints to receive JSON payloads on server events (start, stop, error).
• API Client Libraries: Official Go and JavaScript SDKs simplify integration with other services or custom dashboards.
• Custom Agents: For environments where SSH is unavailable, developers can deploy the lightweight PufferPanel agent on each game server; it exposes a simple TCP protocol for command execution and file management.
• Configuration Files: YAML‑based templates allow declarative server definitions, enabling IaC workflows with tools like Terraform or Ansible.

Developer Experience

The project maintains comprehensive documentation on its site, covering API reference, plugin development guide, and deployment scenarios. The community is active on Discord, providing rapid support for feature requests or bug reports. Licensing is Apache‑2.0, giving developers freedom to modify and redistribute the code without copyleft constraints.

Use Cases

1. Game Server Hosting Providers – Quickly spin up isolated server instances for customers, expose API endpoints for billing integration, and automate backups.
2. Modded Minecraft Networks – Deploy multiple Forge/Spigot servers, manage plugins centrally, and stream logs to a custom dashboard.
3. DevOps Teams – Use the API to trigger server restarts during CI/CD pipelines, integrate with monitoring tools like Prometheus via custom exporters.
4. Educational Environments – Provide students with isolated game server labs, controlling access through RBAC and automated cleanup scripts.

Advantages

• Performance: Go’s compiled binaries deliver low latency server management, and SSE keeps log streaming efficient.
• Flexibility: The plugin architecture allows deep customization without touching the core codebase.
• Open Source & License: Apache‑2.0 permits commercial use and internal modifications without licensing fees.
• Scalability: Stateless API nodes behind a load balancer and shared database enable horizontal scaling.
• Ease of Deployment: Docker images and a minimal configuration file make onboarding fast, while the CLI tool supports advanced scripting.

In summary, PufferPanel offers a robust, extensible platform for developers who need programmatic control over multiple game servers. Its Go‑backed architecture, rich API surface, and plugin system make it a compelling choice for both small hobby projects and large‑scale hosting operations.
