**Tauri** is a tool for building tiny, blazing fast binaries for all
major desktop platforms. It was incubated at Quasar Framework.

Whether you are just starting out making apps for your meetup or
regularly crunch terabyte datasets, we are absolutely confident that
you will love using Tauri as much as we love making and maintaining it.

## Who Tauri is For
Because of the way Tauri has been built and can be extended, developers
are able to interface not only with the entire Rust ecosystem, but also
with many other programming languages. Being freed of the heaviest thing
in the universe and the many shortcomings of server-side Javascript
suddenly opens up whole new avenues for high-performance, security-focused
applications that need the purebred power, agility and community
acceptance of a low-level language.

We expect to witness an entire new class of applications being built with
Tauri. From a simple calender to locally crunching massive realtime
feeds at particle colliders or even mesh-network based distributed message-
passing ecosystems - the bar has been raised and gauntlet thrown.

What will you make?

## 5 Reasons to consider Tauri
- **BUNDLE SIZE** of a vanilla Tauri app is less than 3 MB - about 140 MB smaller than what you get with Electron.
- **MEMORY FOOTPRINT** is less than half of the size of an Electron app built from the same codebase.
- **SECURITY** is Tauri's biggest priority and we take it so seriously that we innovate to keep hackers out of your apps.
- **RELIABILITY** of the underlying code base is why critical libraries have been forked and will be perpetually maintained.
- **FLOSS** licensing is regretfully impossible with downstream Chromium consumers, like Electron.

## Technical Details
The user interface in Tauri apps currently leverages Cocoa/WebKit on macOS,
gtk-webkit2 on Linux and MSHTML (IE10/11) or Webkit via Edge on Windows.
**Tauri** is based on the MIT licensed prior work known as
[webview](https://github.com/zserge/webview).

The default binding to the underlying webview library currently uses Rust,
but other languages like Golang or Python (and many others) are possible
(and only a PR away).

> Rust is blazingly fast and memory-efficient: with no runtime or garbage
collector, it can power performance-critical services, run on embedded
devices, and easily integrate with other languages. Rust’s rich type system
and ownership model guarantee memory-safety and thread-safety — and enable
you to eliminate many classes of bugs at compile-time. Rust has great
documentation, a friendly compiler with useful error messages, and top-notch
tooling — an integrated package manager and build tool, smart multi-editor
support with auto-completion and type inspections, an auto-formatter, and
more. - [https://www.rust-lang.org/](https://www.rust-lang.org/)

This combination of power, safety and usability are why we chose Rust to be
the default binding for Tauri. It is our intention to provide the most safe
and performant native app experience (for devs and app consumers), out of
the box.

To this end, we have spent a great deal of time creating an especially secure
localhost-free backend for the security conscious application-artisans. This
means that your app does not use a localhost server, as is generally the case with
cordova apps. This also has the positive side effect, that less code is needed
and the final binaries are smaller.

> Less code doesn't always mean something is safer, but it does mean that
> there is less surface area for attackers to barnacle themselves.  - Denjell

## Organization
Tauri aims to be a sustainable collective based on principles that guide [sustainable
free and open software communities](https://sfosc.org). You can get involved in many ways.

## Relation to Upstream Origins
We have made the decision to fork, enhance and maintain several upstream
projects here in this repository, in order to guarantee the security of the
code and our ability to enhance it with features that may not be needed for
other consumers.

We hope that this code is useful, but make no claims to suitability or
guarantees that it will work outside of the Quasar ecosystem.

This has been done with our best attempt at due diligence and in
respect of the original authors. Thankyou - this project would never have
been possible without your amazing contribution to open-source and we are
honoured to carry the torch further. Of special note:
- [zserge](https://github.com/zserge) for the original webview approach and
go bindings
- [Boscop](https://github.com/Boscop) for the Rust Bindings
- [Burtonago](https://github.com/burtonageo) for the Cargo Bundle prototype
