Jackett
API Support for your favorite torrent trackers
Jackett works as a proxy server, it translates queries from apps (Sonarr, Radarr, SickRage, CouchPotato, Mylar3, Lidarr, DuckieTV, qBittorrent, Nefarious, etc.) into tracker-site-specific HTTP queries, parses the HTML or JSON response, and then sends results back to the requesting software. This allows for getting recent uploads (like RSS) and performing searches. Jackett is a single repository of maintained indexer scraping & translation logic, removing the burden from other apps. Trackers marked with (invite needed) have no active maintainer and may be missing features or be broken. If your client supports multiple feeds it's recommended to add each indexer directly instead of using all indexers. Using the all indexer has no advantages (besides reduced management overhead). We recommend you install Jackett as a Windows service using the supplied installer. You may also download the zipped version if you would like to configure everything manually. -

Cloudflare Tunnel Client
Cloudflare Tunnel Client
Contains the command-line client for Cloudflare Tunnel, a tunneling daemon that proxies traffic from the Cloudflare network to your origins. This daemon sits between Cloudflare network and your origin (e.g. a webserver). Cloudflare attracts client requests and sends them to you via this daemon, without requiring you to poke holes on your firewall --- your origin can remain as closed as possible. Extensive documentation can be found in the Cloudflare Tunnel section of the Cloudflare Docs. All usages related with proxying to your origins are available under cloudflared tunnel help. You can also use cloudflared to access Tunnel origins (that are protected with cloudflared tunnel) for TCP traffic at Layer 4 (i.e., not HTTP/web socket), which is relevant for use cases such as SSH, RDP, etc. Such usages are available under cloudflared access help. -

UFTP
Encrypted UDP based FTP with multicast
UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers. -

frp
A Fast Reverse Proxy
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. -

Project V
A platform for building proxies to bypass network restrictions
Project V is a set of network tools that helps you to build your own computer network. It secures your network connections and thus protects your privacy. Help you build an exclusive basic communication network. A V2Ray process can concurrently support multiple inbound and outbound protocols, and each protocol can work independently. Inbound traffic can be sent from different outlets according to the configuration. Easily implement distribution by region or domain name to achieve optimal network performance. V2Ray can open multiple protocol support at the same time, including Socks, HTTP, Shadowsoks and VMess. The transmission carrier can be set separately for each protocol, such as TCP, mKCP and WebSocket. Nodes of V2Ray can be disguised as a normal website (HTTPS) to confuse its traffic with normal web traffic to avoid third-party interference. Universal reverse proxy support can achieve intranet penetration. -

OAuth2 Proxy
A reverse proxy that provides authentication with Google, Azure, etc.
A reverse proxy and static file server that provides authentication using Providers (Google, GitHub, and others) to validate accounts by email, domain or group. If you are running a version older than v6.0.0 we strongly recommend you please update to the current version. After returning from the authentication provider, the OAuth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration) oauth2-proxy can be configured via command line options, environment variables or config file (in decreasing order of precedence, i.e. command line options will overwrite environment variables and environment variables will overwrite configuration file settings). -

ShadowsocksR-native is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. It's derived from Shadowsocks-libev. -
19
nginx-proxy
Automated nginx proxy for Docker containers using docker-gen
nginx-proxy sets up a container running nginx and docker-gen. docker-gen generates reverse proxy configs for nginx and reloads nginx when containers are started and stopped. The containers being proxied must expose the port to be proxied, either by using the EXPOSE directive in their Dockerfile or by using the --expose flag to docker run or docker create and be in the same network. By default, if you don't pass the --net flag when your nginx-proxy container is created, it will only be attached to the default bridge network. This means that it will not be able to connect to containers on networks other than bridge. -

Athens
A Go module datastore and proxy
Athens provides a server for Go Modules that you can run. It serves public code and your private code for you, so you don’t have to pull directly from a version control system (VCS) like GitHub or GitLab. There are many reasons why you’d want a proxy server such as security and performance. Athens is a project building on top of vgo (or go1.11+) trying to bring dependencies closer to you so you can count on repeatable builds even at a time when VCS is down. The big goal of Athens is to provide a new place where dependencies — not code — live. Dependencies are immutable blobs of code and associated metadata that come from Github. They live in storage that Athens controls. You probably already know what “immutable” means, but let me just point it out again because it’s really important for this whole system. When folks change their packages, iterate, experiment, or whatever else, code on Athens won’t change. -

sshpiper
The missing reverse proxy for ssh scp
sshpiper is the reverse proxy for sshd. all protocols, including ssh, scp, port forwarding, running on top of ssh are supported. -
23
Fabio
Consul Load-Balancing made simple
Fabio is an HTTP and TCP reverse proxy that configures itself with data from Consul. Traditional load balancers and reverse proxies need to be configured with a config file. The configuration contains the hostnames and paths the proxy is forwarding to upstream services. This process can be automated with tools like consul-template that generate config files and trigger a reload. Fabio works differently since it updates its routing table directly from the data stored in Consul as soon as there is a change and without restart or reloading. When you register a service in Consul all you need to add is a tag that announces the paths the upstream service accepts, e.g. urlprefix-/user or urlprefix-/order and fabio will do the rest. Fabio was developed and maintained by Frank Schröder through January, 2020. Since that date primary maintenance has been the responsibility of ENA and the great community of users. -
