pgrok
HTTP/TCP reverse tunnel solution through SSH remote port forwarding
The pgrok is a multi-tenant HTTP/TCP reverse tunnel solution through remote port forwarding from the SSH protocol. This is intended for small teams that need to expose the local development environment to the public internet, and you need to bring your own domain name and SSO provider. It gives a stable subdomain for every user and gated by your SSO through the OIDC protocol. Think of this as a bare-bones alternative to the ngrok's $65/user/month enterprise tier. Trying to put this behind a production system will blow up your SLA. For individuals and production systems, just buy ngrok, it is still my favorite. -

Interactsh
An OOB interaction gathering server and client library
Interactsh is an open-source tool for detecting out-of-band interactions. It is a tool designed to detect vulnerabilities that cause external interactions. Interactsh Cli client requires go1.17+ to install successfully. interactsh-client with -sf, -session-file flag can be used store/read the current session information from user defined file which is useful to resume the same session to poll the interactions even after the client gets stopped or closed. Running the interactsh-client in verbose mode (v) to see the whole request and response, along with an output file to analyze afterwards. Using the server flag, interactsh-client can be configured to connect with a self-hosted Interactsh server, this flag accepts single or multiple server separated by comma. Default servers are subject to change/rotate/down at any time, thus we recommend using a self-hosted interactsh server if you are experiencing issues with the default server. -

Kafka-Pixy
gRPC/REST proxy for Kafka
Kafka-Pixy is a dual API (gRPC and REST) proxy for Kafka with automatic consumer group control. It is designed to hide the complexity of the Kafka client protocol and provide a stupid simple API that is trivial to implement in any language. Kafka-Pixy is tested against Kafka versions 1.1.1 and 2.3.0, but is likely to work with any version starting from 0.8.2.2. It uses the Kafka Offset Commit/Fetch API to keep track of consumer offsets. However Group Membership API is not yet implemented, therefore it needs to talk to Zookeeper directly to manage consumer group membership. Kafka-Pixy does not support wildcard subscriptions and therefore cannot coexist in a consumer group with clients using them. It should be possible to use other clients in the same consumer group as kafka-pixy instance if they subscribe to topics by their full names, but that has never been tested so do that at your own risk. -

Netgraph
A cross platform http sniffer with a web UI
Netgraph is a packet sniffer tool that captures all HTTP requests/responses, and displays them in a web page. You can run Netgraph in your Linux server without a desktop environment installed, and monitor HTTP requests/responses in your laptop's browser. -

Typhon
A wrapper around Go's net/http to provide safety and convenience
Typhon is a wrapper around Go's net/http library that we use at Monzo to build RPC servers and clients in our microservices platform. A wrapper around Go's net/http to provide safety and convenience. At Monzo, Typhon forms the basis of most clients and servers in our microservices platform. Forgetting to body.Close() in a client when the body has been dealt with is a common source of resource leaks in Go programs in our experience. Typhon ensures that – unless you're doing something really weird with the body – it will be closed automatically. Marshalling and unmarshalling request bodies to structs is such a common operation that our Request and Response objects support them directly. If the operations fail, the errors are propagated automatically since that's nearly always what a server will want. -

distribyted
Torrent client with HTTP, fuse, and WebDAV interfaces
Distribyted is an alternative torrent client. It can expose torrent files as a standard FUSE mount or webDAV endpoint and download them on demand, allowing random reads using a fixed amount of disk space. Distribyted supports several ways to expose the files to the user or external applications. Applications that supports WebDAV can access torrent files using this protocol. It is recommended when distribyted is running in a remote machine or using docker. Distribyted can show some kind of files directly as folders, making it possible for applications to read only the parts that they need. Here is a list of supported, to-be-supported, and not supported formats. Play multimedia files on your favorite video or audio player. These files will be downloaded on demand and only the needed parts. -

plow
A high-performance HTTP benchmarking tool
Plow is an HTTP(S) benchmarking tool, written in Golang. It uses excellent fast HTTP instead of Go's default net/http due to its lightning-fast performance. Plow runs at specified connections (option -c) concurrently and real-time records summary statistics, histogram of execution time and calculates percentiles to display on Web UI and terminal. It can run for a set duration( option -d), for a fixed number of requests(option -n), or until Ctrl-C is interrupted. The implementation of real-time computing Histograms and Quantiles using stream-based algorithms inspired by Prometheus with low memory and CPU bounds. so it's almost no additional performance overhead for benchmarking. -

sish
HTTP(S)/WS(S)/TCP Tunnels to localhost using only SSH
An open source serveo/ngrok alternative. Builds are made automatically for each commit to the repo and are pushed to Dockerhub. Builds are tagged using a commit sha, branch name, tag, latest if released on main. Each release builds separate sish binaries that can be downloaded from here for various OS/archs. Feel free to either use the automated binaries or to build your own. If you submit a PR, images are not built by default and will require a retag from a maintainer to be built. You can also use Docker Compose to setup your sish instance. This includes taking care of SSL via Let's Encrypt for you. This uses the adferrand/dnsrobocert container to handle issuing wildcard certifications over DNS. SSH can normally forward local and remote ports. This service implements an SSH server that only handles forwarding and nothing else. The service supports multiplexing connections over HTTP/HTTPS with WebSocket support. -

EGO
A simple and component-based microservice kit for go
EGO is a microservice-oriented governance framework implemented by golang, which integrates various engineering practices. Through the component-based design pattern, it is guaranteed that the business development can use various components in a unified way. For us engineers to improve component proficiency, we must first read a lot of open-source component documentation and code, and then insist on using it for a long time in order to form muscle memory and improve our speed of doing business. And the time and energy invested in all of this is enormous. To reduce this input cost and allow more developers to better use excellent open source components, EGO's approach is to standardize all open source components, encapsulate them, and unify various behaviors. -
16
Gzip Handler
Go middleware to gzip HTTP responses
This is a tiny Go package that wraps HTTP handlers to transparently gzip the response body, for clients which support it. Although it's usually simpler to leave that to a reverse proxy (like nginx or Varnish), this package is useful when that's undesirable. Call GzipHandler with any handler (an object which implements the http.Handler interface), and it'll return a new handler which gzips the response. -

Promxy
An aggregating proxy to enable HA prometheus
Promxy is a prometheus proxy that makes many shards of prometheus appear as a single API endpoint to the user. This significantly simplifies operations and use of prometheus at scale (when you have more than one prometheus host). Promxy delivers this unified access endpoint without requiring any sidecars, custom-builds, or other changes to your prometheus infrastructure. Prometheus itself provides no real HA/clustering support. As such the best-practice is to run multiple (e.g N) hosts with the same config. Similarly prometheus has no real built-in query federation, which means that you end up with N sources in grafana which is (1) confusing to grafana users and (2) has no support for aggregation across the sources. Promxy enables an HA prometheus setup by "merging" the data from the duplicate hosts (so if there is a gap in one, promxy will fill with the other). In addition Promxy provides a single datasource for all promql queries. -
18
Switcher
Run SSH and HTTP(S) on the same port
Switcher is a proxy server that accepts connections and proxies based on which protocol is detected. Switcher is heavily influenced by sslh. It started out as a learning exercise to discover how sslh worked and attempt an implementation in Go. The result is useful in its own right through use of Go's interfaces for protocol matching (making adding new protocols trivial), and lightweight goroutines (instead of forking, which is more CPU intensive under load). -

faasd
A lightweight & portable faas engine
faasd is OpenFaaS reimagined but without the cost and complexity of Kubernetes. It runs on a single host with very modest requirements, making it fast and easy to manage. Under the hood it uses containers and Container Networking Interface (CNI) along with the same core OpenFaaS components from the main project. To deploy microservices and functions that you can update and monitor remotely. When you don't have the bandwidth to learn or manage Kubernetes. To deploy embedded apps in IoT and edge use-cases. To distribute applications to a customer or client. You have a cost sensitive project - run faasd on a 1GB VM for 5-10 USD / mo or on your Raspberry Pi. When you just need a few functions or microservices, without the cost of a cluster. -

gentleman
Plugin-driven, extensible HTTP client toolkit for Go
Full-featured, plugin-driven, middleware-oriented toolkit to easily create rich, versatile and composable HTTP clients in Go. gentleman embraces extensibility and composition principles in order to provide a flexible way to easily create featured HTTP client layers based on built-in or third-party plugins that you can register and reuse across HTTP clients. As an example, you can easily provide retry policy capabilities or dynamic server discovery in your HTTP clients simply attaching the retry or consul plugins. Take a look to the examples, list of supported plugins, HTTP entities or middleware layer to get started. For testing purposes, see baloo, a utility library for expressive end-to-end HTTP API testing, built on top of gentleman toolkit. For HTTP mocking, see gentleman-mock, which uses gock under the hood for easy and expressive HTTP client request mocking. -

immortal
A *nix cross-platform (OS agnostic) supervisor
A *nix cross-platform (OS agnostic) supervisor. The main idea behind immortal is to keep up and running services forever even if the server is rebooted the service should be started and based on the requirements probably the services may start in sequence by waiting for others to start, wait some seconds before starting, etc, but at the end the idea remains, “run something forever” and in case exist just restart it. Doing this could be tricky, mainly because if you just want to launch your service/worker/daemon, etc you may not want to spend to much time understanding how to properly launch something in the operating system your company is using. Probably you just join a new team and when are about to deploy, found out that the production servers are not using the OS you were used to besides they don’t support/have your known supervisor, have a mix of init/upstart scripts. -
23
req
Simple Go HTTP client with Black Magic
Simple and easy to use, providing rich client-level and request-level settings, all of which are intuitive and chainable methods. Provides powerful and convenient debug utilities, including debug logs, performance traces, and even dump the complete request and response content. API testing can be done with minimal code, no need to explicitly create any Request or Client, or even to handle errors. Detect and decode to utf-8 automatically if possible to avoid garbled characters (See Auto Decode), marshal request body and unmarshal response body automatically according to the Content-Type. Req support HTTP/1.1, HTTP/2, and HTTP/3, and can automatically detect the server side and select the optimal HTTP version for requests, you can also force the protocol if you want. Support automatic request retry and is fully customizable. -
24
schema
Package gorilla/schema fills a struct with form values
Package gorilla/schema converts structs to and from form values. Conversely, the contents of a struct can be encoded into form values. To define custom names for fields, use a struct tag "schema". To not populate certain fields, use a dash for the name and it will be ignored.
