PortFusion is a minimalistic, cross-platform, transport-layer distributed reverse / forward proxy and tunneling solution for TCP released under GPLv3.
A single package that makes the most of each platform by tapping into their unique capabilities, combining this power with an intuitive interface, beautiful design and Haskell's excellent support for unprecedented levels of concurrency and parallelism.
It strives for the smallest source code size while delivering maximum throughput with near-zero overhead.
Today, a growing number of companies and institutions around the world use PortFusion.
PortFusion is a tiny command line application.

PortFusion is available and can be very easily installed from Hackage:
cabal update
cabal install splice -f llvm
cabal install PortFusion -f llvmIf you do not have LLVM installed, you can drop -f llvm.

Development follows simple principles:
- Be concise: PortFusion is a single-file with less than 500 lines of code
- Be relentless: refactor and prune constantly
- Be open: share everything
- Create fully documented reusable libraries that cover common needs
- Use the most permissive licenses possible
- Report bugs in external code and work on fixes
- Illustrate every concept in publication-worthy detail
- Be friendly: provide excellent support to users
I had already spent a great deal of time contemplating a nice and intuitive syntax and it was only when I watched the Japanese movie Hayabusa about the same-named space probe sent to extract and bring to Earth pieces from the asteroid Itokawa that everything just fell into place:
# command line # source file
] [ :><: # serve
- [ :-<: # reverse
] - :>-: # forward
# > and < are reserved characters at command line
# ] and [ are reserved characters in Haskell
PortFusion owes its design goals, ambitions and 1.0 release name ]-[ayabusa to the great Japanese culture and friends.
We hope to grow a whole family of software-defined networking solutions reaching all network layers, technologies and devices.
For their continuing support and inspiration, we extend our heart-felt thanks to:
