Lucky is a port forwarding and network utility tool that runs on Linux embedded devices and routers.
Lucky addresses the need for flexible network access and service exposure on resource-constrained devices. It originated as a personal tool to replace socat for exposing internal IPv4 services over public IPv6 on consumer routers. The tool is built entirely in Go for efficiency and cross-platform compatibility, with a Vue 3.2 frontend and a REST API that third-party developers can integrate with. Its core capabilities include IPv6 and IPv4 port forwarding, reverse proxying, dynamic DNS, network wake-on-LAN, scheduled tasks, automatic certificate management via ACME, and network storage access through FTP, WebDAV, and file browser interfaces. It also includes STUN-based NAT traversal for accessing services behind restrictive firewalls.
The tool suits users running custom firmware on routers or embedded Linux systems who need to expose internal services without complex infrastructure. It is designed to minimize setup complexity and learning overhead for non-technical users while maintaining network security awareness. The project maintains a web-based management interface for configuration and monitoring.
Development has been active with regular iteration based on user feedback and feature requests. The maintainer has stated that source code is published up to a specific version with no plans for continued open-source releases beyond that point. The project is no longer accepting contributions as free labor, with the developer prioritizing their own vision for the tool's direction over community-driven development.
