WHY ARE SNAPS GOOD FOR C/C++ PROJECTS?

 * Snaps are easy to discover and install. Millions of users can browse and
   install snaps graphically in the Snap Store or from the command-line.
 * Snaps install and run the same across Linux. They bundle the exact versions
   of your app’s dependencies.
 * Snaps automatically update to the latest version. Four times a day, users’
   systems will check for new versions and upgrade in the background.
 * Upgrades are not disruptive. Because upgrades are not in-place, users can
   keep your app open as it’s upgraded in the background.
 * Upgrades are safe. If your app fails to upgrade, users automatically roll
   back to the previous revision.

In just a few steps, you’ll have an example C/C++ app in the Snap Store.

WHY ARE SNAPS GOOD FOR ELECTRON PROJECTS?

 * Snaps are easy to discover and install. Millions of users can browse and
   install snaps graphically in the Snap Store or from the command-line.
 * Snaps install and run the same across Linux. They bundle Electron and all of
   your app’s dependencies, be they Node modules or system libraries.
 * Snaps automatically update to the latest version. Four times a day, users’
   systems will check for new versions and upgrade in the background.

WHY ARE SNAPS GOOD FOR GO PROJECTS?

 * Easy to discover and install by millions using the Snap Store or command-line
   every day
 * Automatically updated to the latest stable version of your app
 * Revert to the previous version if an update fails, preserving data

Programming in Go makes it easy to create a zip of your app that runs across
Linux, without dependencies. However, end user discovery and update management
remain a challenge. Snaps fill this gap, letting you distribute a Go app in an
app store experience for end users.

In just a few steps, you’ll have an example Go app in the Snap Store.

WHY ARE SNAPS GOOD FOR JAVA PROJECTS?

 * Simplify installation instructions, regardless of distribution, to snap
   install myjavaapp.
 * Directly control the delivery of automatic application updates.

Distributing a Java application for Linux and reaching the widest possible
audience is complicated. Typically, the user has to make sure the JRE/SDK
version and their environment are configured correctly. When a Linux
distribution changes the delivered JRE, this can be problematic for
applications. Snapcraft ensures the correct JRE is shipped alongside the
application at all times.

In just a few steps, you’ll have an example Java app in the Snap Store.

WHY ARE SNAPS GOOD FOR MOOS PROJECTS?

 * Bundle all the runtime requirements, including the exact version of
   MOOS/MOOS-IvP and system libraries you need.
 * Directly and reliably control the delivery of application updates using
   existing infrastructure.
 * Upgrades are safe. If your app fails to upgrade, users automatically roll
   back to the previous revision.
 * Extremely simple creation of daemons.

In just a few steps, you’ll have an example MOOS app in the Snap Store.

 * Easy to discover and install by millions using the Snap Store or command-line
   every day.
 * Automatically updated to the latest stable version of your app.
 * Revert to the previous version if an update fails, preserving data.

With npm you can distribute apps to other developers, but it’s not tailored to
end users. Snaps let you distribute your Node app in an app store experience.

In just a few steps, you’ll have an example Node.js app in the Snap Store.

--------------------------------------------------------------------------------


HERE'S HOW WETHR DEFINES SNAPCRAFT.YAML:

   every day
 * Automatically updated to the latest stable version of your app
 * Revert to the previous version if an update fails, preserving data
 * Isolation ensures no conflicts between applications
 * Identical behaviour across Linux distributions, even with library
   dependencies

Distributing the Linux build of your app as a zip lets you provide one download
and set of instructions for all of Linux. However, end user discovery and update
management remain a challenge. Snaps fill this gap, letting you wrap your
existing Linux build in an app store experience for end users.

In just a few steps, you’ll have an example pre-built app in the Snap Store.

 * Automatically updated to the latest stable version of your app
 * Revert to the previous version if an update fails, preserving data
 * Isolation ensures no conflicts between applications
 * Identical behaviour across Linux distributions, even with library
   dependencies

With PyPI you can distribute apps to other developers, but it’s not tailored to
end users. Virtualenv lets you install an app’s dependencies in isolation, but
it’s not automatically used for installs from PyPI. Snaps let you distribute a
dependency-isolated Python app in an app store experience for end users.

In just a few steps, you’ll have an example Python app in the Snap Store.

WHY ARE SNAPS GOOD FOR RUBY PROJECTS?

 * Bundle all the runtime requirements.
 * Simplify installation instructions, regardless of distribution, to snap
   install myrubyapp.
 * Directly control the delivery of automatic application updates.
 * Extremely simple creation of services.

Linux install instructions for Ruby applications often get complicated. To
prevent modules from different Ruby applications clashing with each other,
developer tools like rvm or rbenv must be used. With snapcraft, it’s one command
to produce a bundle that works anywhere.

In just a few steps, you’ll have an example Ruby app in the Snap Store.

 * Automatically updated to the latest stable version of your app.
 * Revert to the previous version if an update fails, preserving data.

You can distribute your apps across Linux using a musl-enabled version of Rust,
with all the dependencies satisfied. However, end user discovery and update
management remain a challenge. Snaps fill this gap, letting you distribute a
Rust app in an app store experience for end users.

In just a few steps, you’ll have an example Rust app in the Snap Store.

TESTIMONIALS


“THE AUTO-UPDATING FEATURE IS HUGE”

> Due to the nature of our platform, we release updates more than daily which
> admittedly can be annoying for our users to constantly update.
> 
> Therefore, having them done seamlessly in the background makes life for our
> users so much easier. It’s great to see snaps as the first serious attempt to
> try and unify the community.
> 
> Jeff Dickey
> CLI engineer, Heroku

--------------------------------------------------------------------------------


“STARTING WITH SNAPS
IS EASY”

> We definitely find Snapcraft easier as it is yaml based and provides details
> of what artifacts are needed. Debian packaging has things that need to be
> followed which can be distribution specific, which creates complication.
> 
> The modular containment is what appealed about snaps and [we] can see it will
> be a lot more flexible. Starting with snaps is easy and the resources that are
> provided are clean and structured which aids adoption.
> 
> Lee Coward and Rakesh Singh
> .NET (Microsoft)

--------------------------------------------------------------------------------


“A MAJOR SOFTWARE DISCOVERY TOOL”

> The Snap store provides additional exposure to our tools for many of our
> existing and potential users. The decision to use it came quite naturally. We
> believe the store will be a major software discovery tool on Linux, so the
> more people find out about our tools naturally and install them more easily,
> the better for everyone.
