Goals

Syncthing is a continuous file synchronization program. It synchronizes
files between two or more computers. We strive to fulfill the goals below.
The goals are listed in order of importance, the most important one being
the first. This is the summary version of the goal list - for more
commentary, see the full Goals document.

Syncthing should be:

1. undefinedSafe From Data Lossundefined

   Protecting the user’s data is paramount. We take every reasonable
   precaution to avoid corrupting the user’s files.

2. undefinedSecure Against Attackersundefined

   Again, protecting the user’s data is paramount. Regardless of our other
   goals we must never allow the user’s data to be susceptible to
   eavesdropping or modification by unauthorized parties.

3. undefinedEasy to Useundefined

   Syncthing should be approachable, understandable and inclusive.

4. undefinedAutomaticundefined

   User interaction should be required only when absolutely necessary.

5. undefinedUniversally Availableundefined

   Syncthing should run on every common computer. We are mindful that the
   latest technology is not always available to any given individual.

6. undefinedFor Individualsundefined

   Syncthing is primarily about empowering the individual user with safe,
   secure and easy to use file synchronization.

7. undefinedEverything Elseundefined

   There are many things we care about that don’t make it on to the list. It
   is fine to optimize for these values, as long as they are not in conflict
   with the stated goals above.

Getting Started

Take a look at the getting started guide.

There are a few examples for keeping Syncthing running in the background
on your system in the etc directory. There are also several GUI
implementations for Windows, Mac and Linux.

Vote on features/bugs

We’d like to encourage you to vote on issues that matter to you.
This helps the team understand what are the biggest pain points for our users, and could potentially influence what is being worked on next.

Getting in Touch

The first and best point of contact is the Forum. There is also an IRC
channel, #syncthing on freenode (with a web client), for talking
directly to developers and users. If you’ve found something that is clearly a
bug, feel free to report it in the GitHub issue tracker.

Building

Building Syncthing from source is easy, and there’s a guide
that describes it for both Unix and Windows systems.

Signed Releases

As of v0.10.15 and onwards release binaries are GPG signed with the key
D26E6ED000654A3E, available from https://syncthing.net/security.html and
most key servers.

There is also a built in automatic upgrade mechanism (disabled in some
distribution channels) which uses a compiled in ECDSA signature. macOS
binaries are also properly code signed.
