Detailed Introduction

frp is an open-source, high-performance reverse proxy designed to bridge the gap between local servers and the public internet. It enables users to securely expose services running behind restrictive NATs or firewalls, making them accessible globally. Beyond basic port forwarding, frp supports a wide array of protocols including TCP, UDP, HTTP, and HTTPS, with advanced features like domain-based routing, P2P connectivity, and robust security measures such as TLS encryption and OIDC authentication. It's an essential tool for developers, system administrators, and anyone needing to access internal resources remotely without complex network configurations.
