frp stands for exactly what it is: a fast reverse proxy. It helps you expose a local server behind a NAT or firewall to the Internet. It is currently under development, but already supports TCP and UDP, as well as HTTP and HTTPS protocols where requests can be forwarded to internal services by domain name. It also has a P2P connect mode and many other nifty features. These include configuration files, environment variables, a dashboard that shows you frp's status and proxies' statistics information, an Admin UI that helps you check and manage frpc's configuration, and many others.

Like libevent, libev, and libuv, libhv provides event loop with non-blocking IO and timer, but simpler api and richer protocols. Cross-platform (Linux, Windows, MacOS, BSD, Solaris, Android, iOS) High-performance EventLoop (IO, timer, idle, custom) TCP/UDP client/server/proxy. TCP supports heartbeat, reconnect, upstream, MultiThread-safe write and close, etc. Built-in common unpacking modes (FixedLength, Delimiter, LengthField) RUDP support: WITH_KCP. SSL/TLS support: (via WITH_OPENSSL or WITH_GNUTLS or WITH_MBEDTLS) HTTP client/server (support https http1/x http2 grpc). HTTP supports static service, indexof service, proxy service, sync/async API handler. ...

paqet is a bidirectional packet-level proxy that transports traffic over raw packets instead of relying on the host operating system’s normal TCP/IP stack. It forwards traffic between a local client and a remote server using KCP as the reliable transport layer. The project is written in Go and is aimed at users who need a low-level tunnel that can operate in restricted or heavily filtered network environments.

...In HTTP mode when the server received some data it can't just send them to the client directly because HTTP is not bi-directional, instead, the server must wait until the client requests them, which means these data will be stored in memory for some time.

GSnova is a high-performance proxy tool for bypassing internet censorship and securing network traffic through a range of supported transport protocols. It acts as a multi-protocol client/server proxy that can tunnel traffic over TLS, WebSocket, KCP, QUIC, and SSH. GSnova is optimized for resilience and speed under restrictive network conditions and supports multiple fronting strategies and obfuscation techniques.
