You are in control

Why would you trust a closed, proprietary software with your most-sensitive data ?

Freelan isopen-source andcompletely free. You know everything about its internals and its source-code.You are in complete control of the software and your data.You, and nobody else.

Choose your network topology

Freelan allows you to create any kind of network topology you like: from the classical clients-server schema, to the completely crazy hybrid peer-to-peer decentralized graph.

You decide. Freelan does it.

Security matters

Freelan was designed from the start with security as the main concern.

It uses only standard, well-established cryptographic algorithms and makes sure thatyour communications are completely opaque to the outside world.

Stability and transparency

Freelan is written in robust, low-level C and C++ code. It has been thoroughly tested for both stability and performance.

It runs transparently as a service in the background: you just have to install it, configure it, andyou can simply forget about it.

Seamless integration

Freelan is designed as several distinct C++ multi-platform libraries, maintained separately and availablefor free under theGPL license.

Whether you want to create a graphical user interface for it or embed it into your own product, everything is possible ! Oh, andyou will have support from the community as well !

client-server graph

Client-server

Freelan can, of course, be configured to act according to the usualclient-server pattern, like any other VPN software.

In this configuration, one or several clients connect to the server, which may or may not allow clients to communicate with one another. The server does not necessarily need to be part of the network and can even act as a simple relay.

Go to the configuration examples
peer-to-peer graph

Peer-to-peer

The client-server pattern is nice, but it is also a bit fragile. What happens to your connectivity if the server falls for some reason ?

For more robust networks, freelan can be configured as apeer-to-peer network, where each node can connect directly to all the others. This configuration also brings better performances since traffic between two nodes doesn't need to go through a third node anymore.

Go to the configuration examples
hybrid graph

Hybrid

What if you would like to mix the benefits of both the client-server and peer-to-peer patterns ?

Freelan actually allows for all kinds of connectivity graphs. Some hosts can be connected to some others, but not all of them. You are free to pick the topology you desire, even anhybrid one.

Need 3 servers and peer-to-peer connection between hosts ? Just go ahead !

A VPN software...Does that mean I can access the Internet anonymously ?

Freelan is ageneric VPN software, not a Web proxy service.

It is important to understand the difference: while freelan can indeed be used to create a service likeVPN Tunnel, it isnot a service. But have no fear: if your goal is to surf anonymously on the Internet, and you want to use freelan for that, you willget help from the community to set it up.

Just keep in mind that freelan has a broader purpose and can be used for much more than just anonymous surfing. You can, for instance:

  • Create a private network for your friends and/or family.
  • Securely connect to your enterprise or personal network from the outside world.
  • Implement freelan in your own software and use it as a basis for secure communications.
  • ... or just anything you want !

The only limit, is your imagination.

Open-sourceHow else would you trust a software ?

Freelan is free software, released under theGPLv3 license. By "free", we both mean free as in "free beer" and free as in "freedom". You will never pay a dime to download, use or update the software: everything comes for free, forever.

You can easily access thesource code and make sure what happens to your data. We believe this is paramount when dealing with security software: if the source-code is closed to your eyes, how can you be sure that it does what it claims ? How can you be sure it contains no security flaws ?

Being free software means you can use freelan's code in your ownfree project to create awesome stuff ! Do whatever you want, and share it with others in turn !

If you would like to integrate freelan into commercial apps, do not hesitate tocontact us. Depending on the nature of your project, this might be free as well: freelan was not created for profit, but to give people control over their data. If your goal is the same, we might find an agreement !

You have nothing to hide...Not that it is anyones business !

The importance of communicating securely has never made more sense than today: whether it is governments spying on your confidential exchanges or companies abusing your trust, more and more people feel the need of communicating securely.

Freelan was designed with security and your privacy as the main concern: its open-source code can be reviewed at any time by anyone to search for potential weaknesses. Itsprotocol specification is clearly accessible and described: you know exactly what happens and when.

You have nothing to hide, but do you really want to give full disclosure ?
