# [Enso.org](https://enso.org). Get insights you can rely on. In real time.



Enso is an award-winning interactive programming language with dual visual and

textual representations. It is a tool that spans the entire stack, going from

high-level visualization and communication to the nitty-gritty of backend

services, all in a single language. Watch the following introduction video to

learn what Enso is, and how it helps companies build data workflows in minutes

instead of weeks.

# Enso's Features



Turning your data into knowledge is slow and error-prone. You can’t trust tools

that don’t embrace best practices and provide quality assurance. Enso redefines

the way you can work with your data: it is interactive, provides intelligent

assistance, and was designed on a strong mathematical foundation, so you can

always trust the results you get.





      

          Intelligent suggestions of possible next steps. Build workflows in minutes instead of weeks.
      

          Enso analyses the data, suggests possible next steps, and displays related

          help and examples. It lets you build dashboards, RPA workflows, and apps,

          with no coding required. Enso ships with a robust set of libraries, allowing

          you to work with local files, databases, HTTP services, and other

          applications in a seamless fashion.

          Reproducible, trustworthy results.
      

          Versioning and visual data quality management allow you to trust the results

          that you get.

          A powerful, purely functional language. Both visual and textual.
      

          Enso incorporates many recent innovations in data processing and programming

          language design to allow you to work interactively and trust the results

          that you get. It is a purely functional programming language with

          higher-order functions, user-defined algebraic datatypes, pattern-matching,

          and two equivalent representations that you can switch between on-demand.

          Mix languages with close-to-zero interop overhead.
      

          Import any library from Enso, Java, JavaScript, R, or Python, and use

          functions, callbacks, and data types without any wrappers. Enso uses

          GraalVM to compile them to the same

          instruction set with a unified memory model.

          A cutting-edge visualization engine.
      

          Enso is equipped with a highly-tailored WebGL visualization engine capable

          of displaying many millions of data points at 60 frames per second in a web

          browser. Currently, Enso includes a set of core data visualizations out of

          the box, and you can easily extend it with libraries such as D3.js,

          Three.js, Babylon.js, deck.gl, VTK.js, Potree, and many more.

          Runs everywhere.
      

          Enso is available on macOS, Windows, and GNU/Linux, and the Enso IDE runs on

          web-native technologies. In time, you'll be able to run it in the

          web-browser, giving even your tablet and phone access to your data.

# Enso Source Code



If you want to start _using_ Enso, please see the download links in the

[getting started](#getting-started) section above. Alternatively, you can get

the IDE [here](https://github.com/enso-org/enso/releases). This section is

intended for people interested in contributing to the development of Enso.



Enso is a community-driven open source project which is, and will always be,

open and free to use. Join us, help us to build it, and spread the word!







### Project Components



Enso consists of several sub projects:



- **Enso Engine:** The Enso Engine is the set of tools that implement the Enso

  language and its associated services. These include the Enso interpreter, a

  just-in-time compiler and runtime (both powered by

  [GraalVM](https://www.graalvm.org)), and a language server that lets you

  inspect Enso code as it runs. These components can be used on their own as

  command line tools.



- **Enso IDE:** The

  [Enso IDE](https://github.com/enso-org/enso/tree/develop/app/gui) is a desktop

  application that allows working with the visual form of Enso. It consists of

  an Electron application, a high performance WebGL UI framework, and the

  searcher which provides contextual search, hints, and documentation for all of

  Enso's functionality.







### License



The Enso Engine is licensed under the

[Apache 2.0](https://opensource.org/licenses/apache-2.0), as specified in the

[LICENSE](https://github.com/enso-org/enso/blob/develop/LICENSE) file. The Enso

IDE is licensed under the [AGPL 3.0](https://opensource.org/licenses/AGPL-3.0),

as specified in the

[LICENSE](https://github.com/enso-org/enso/blob/develop/app/gui/LICENSE) file.



This license set was chosen to provide you with complete freedom to use Enso,

create libraries, and release them under any license of your choice, while also

allowing us to release commercial products on top of the platform, including

Enso Cloud and Enso Enterprise server managers.







### Contributing to Enso



Enso is a community-driven open source project which is and will always be open

and free to use. We are committed to a fully transparent development process and

highly appreciate every contribution. If you love the vision behind Enso and you

want to redefine the data processing world, join us and help us track down bugs,

implement new features, improve the documentation or spread the word!



If you'd like to help us make this vision a reality, please feel free to join

our [chat](https://discord.gg/enso), and take a look at our

[development and contribution guidelines](./docs/CONTRIBUTING.md). The latter

describes all the ways in which you can help out with the project, as well as

provides detailed instructions for building and hacking on Enso.



If you believe that you have found a security vulnerability in Enso, or that you

have a bug report that poses a security risk to Enso's users, please take a look

at our [security guidelines](./docs/SECURITY.md) for a course of action.







### Enso's Design



If you would like to gain a better understanding of the principles on which Enso

is based, or just delve into the why's and what's of Enso's design, please take

a look in the [`docs/` folder](./docs/). It is split up into subfolders for each

component of Enso. You can view this same documentation in a rendered form at

[the developer docs website](https://enso.org/docs/developer).



This folder also contains a document on Enso's

[design philosophy](./docs/enso-philosophy.md), that details the thought process

that we use when contemplating changes or additions to the language.



This documentation will evolve as Enso does, both to help newcomers to the

project understand the reasoning behind the code, and also to act as a record of

the decisions that have been made through Enso's evolution.
