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.
PortFusion is a tiny command line application.

You may only distribute unchanged official binaries using the PortFusion and Corsis Marks. If you're taking full advantage of the open-source nature of Corsis products and making significant functional changes, you may not redistribute the fruits of your labor under any Corsis trademark, without prior written consent from Corsis. For example, if you've modified PortFusion, you may not use Corsis or PortFusion, in whole or in part, in your product name. Also, it would be inappropriate for you to say "based on Corsis PortFusion". Instead, in the interest of complete accuracy, you could describe your executables as "based on PortFusion technology", or "incorporating PortFusion source code." In addition, a "Powered by PortFusion" logo will be made available.

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
- Be friendly: provide excellent support to users
Japanese Influence: ]-[ayabusa (はやぶさ) (Hayabusa)
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.
