Visual Javascript is a tool for building webapps on your intranet. It runs on PC/Mac (desktop application or NodeJS), Linux/Windows (via NodeJS), or as a container (Docker, Kubernetes). To develop an app:
- Start Visual Javascript
- Create an app in your web browser
- Share the app with others by sending them the app URL
Visual Javascript is perfect for small internal web apps or microservices. Some demo apps can be found at https://yazz.com (Yazz sponsors development of the tool).
- Easy to use: Drag and drop interface (like Visual Basic, except it uses Javascript instead of Basic for scripting)
- Permissive license: Open source MIT license so you can do whatever you want with it
- Easy to distribute apps: Apps can be exported to a single HTML file and sent by email (even SQLite database apps)
- Works almost anywhere: Windows, Linux, Mac, Raspberry PI, NodeJS, Docker, Kubernetes, OpenShift, Istio
- Works offline: Editor works both locally and offline
- Reuse existing databases: Can read MS Access databases (even Linux or Mac can read MS Access files)
- Build desktop apps as a series of forms
- Add components to a form, such as buttons, images, input fields
- Add interactivity using Javascript
- Connect to databases such as Postgres, Mysql
- Connect to REST APIs
- Connect the outputs of one component to the inputs of another
- Build Microservices
- Each app has a built in SQLite database
- App source code saved as a single .vjs file
- Build slick UIs for public facing websites
- Build mobile apps
- Build self contained executables (need to pass in a .vjs file)
- High performance apps
- Low level systems

Visual Javascript is a tool to build internal web applications. Applications are built using pre-built graphical and server side components, with glue code written in Javascript. Visual Javascript can run on Windows, OsX (via the Mac App store), and Kubernetes and Docker containers. Ideally Visual Javascript is used for small throwaway or demo apps, but can also be used for more complex apps since it also contains an embedded SQLite database.
Visual Javascript's killer feature is the ability to create simple webapps extremely fast, on almost any platform, with no licensing or troublesome installation procedures. The application can then be distributed as a single HTML file WITHOUT even needing the original Visual Javascript runtime.
An ideal user for Visual Javascript is someone who wants to build small web apps for internal use (such as demos), or someone who wants to do small data processing tasks. So far there have been independant people and large enterprises have used Visual Javascript for building demos and for small data processing tasks.
When we say Self Service we mean that Visual Javascript can be used by people who are not professional programmers. This is possible because Visual Javascript has a drag and drop user interface which makes it easy for "non techies" to design and build applications. Also, many components included in Visual Javascript have a custom design time graphical editor which make it easy to configure them.
Visual Javascript is free to download and use. It uses the MIT license so you are free to copy and distribute Visual Javascript applications that you build. Yazz, the company behind Visual Javascript may release a paid hosted version at some point which will most likely be a web based service (like hosted Wordpress).
Yes, Visual Javascript is production ready and has been used in many enterprise environments.
If you require commercial support then please go to https://yazz.com. If you want a consulting assignment with Visual Javascript our email is contact@yazz.com
Visual Javascript is Open Source so you can download the opensource repo or fork the Github repo. Visual Javascript is also based on VueJS, HTML, and Javascript so you can slowly migrate applications off Visual Javascript to similar technologies in the Javascript ecosystem if needed.
Visual Javascript's long term vision is to make personal automation and embedded medical applications easy to build. An example of a medical device is a tiny device that is injected into the blood stream to detect and destroy dangerous cells (using tiny cameras and Tensorflow). To get to this long term goal we need to take many tiny steps on the way. First we need to succeed with desktop web applications, and to create an app store for internal enterprise apps and components. Next we need to miniturise the system to work in embedded and internal environments, and finally we need support for autonomous systems which use autodiscovery of components which can be loaded on demand. As an example of why autodiscovery is important is for a medical application where an unrecognised cell type in the human body is found by computer vision, Visual Javascript could go out to the network to see if this cell is recognized somewhere else and download the particular code related to that cell type to detect if it is dangerous or not.
For the first 3 years the author, Zubair used Clojure/Clojurescript for the development of Visual Javascript. But in 2016 Zubair switched from Clojure/Clojurescript as he thought that the product was limiting itself to a very small subset of developers, whereas Javascript has a much larger developer pool.
No. Since Visual Javascript uses Javascript as the scripting language instead of Basic there is zero compatibility with Visual Basic.
Think of Visual Javascript as a Swiss Army Knife tool for building small internal applications. It is a good general purpose tool for quick and dirty tasks such as calculating a few numbers, or visualising an API, but not meant for heavy duty specialist work such as responsive websites, or internet commerce websites. While there are many existing tools in the low code space, most of them are either paid SAAS products, or developer focused open source products, often with complex installation procedures. Unlike many other tools Visual Javascript is both open source and easy to install.
The author of Visual Javascript is a huge fan of Visual Basics. Visual Javascript is trying to recreate the essence of the Visual Basic component ecosystem from the 1990s, but in Javascript.
In Visual Basic the VBA language has been embedded in many other languages, such as Excel, but Visual Javascript is a bit different. The runtime is meant to be used standalone and connect to other systems such as Excel via components. In fact everything in Visual javascript is just a component, including the Visual Javascript drag and drop editor, which can also be replaced. For example, planned for the future is to offer other development paradigms such as a VR/AR editor using Oculus Quest and WebXR.
Beads is a very interesting product which has some things in common with Visual Javascript such as the debugger, but some other things are totally opposite like Beads has invented their own language and syntax. However, Visual Javascript definitely takes some inspiration from Beads. Here is a recent thread on Beads on Hacker News to find out more about it: https://news.ycombinator.com/item?id=27287989
Unison is an exellent language for distributed computing. There is no relation except that both Unison and Visual Javascript are based on the principal of immutable code where code is addressed by the SHA256 of the source code which means that the Visual Javascript internally identifies all code as the SHA256 hash of the source code.
There is no real relation as StoryScript is a Glue code for multiple languages using AI and plain English language to interact with them, whereas Visual Javascript is more where the user has be very intentional and choose which components to interact with by to dragging and dropping components onto a form and connecting them together using links and Javascript.
Full disclosure, the creator of Visual Javascript was the initial angel investor in Eve. Some concepts of universality are taken from Eve. Eve invented a new language to build systems using reactive concepts, but Visual Javascript uses it's own language and is not as reactive.
How does Visual Javascript compare to https://www.anytype.io/?
Anytype is more of an internet operating system. As of June 2021 AnyType is still closed source. Anytype does use IPFS for storage which is a technology, along with QRI that Visual Javascript is considering for data storage.
As of May 2021 Retool is a great paid SAAS offering. We can recommend Retool for anyone who wants a paid SAAS offering with great support.
First off, Visual Javascript, uses VueJS under the hood to build UI components. Visual Javascript is very different to all those frameworks as Visual Javascript does not require deep coding skills or knowledge of HTML. You do need to know some Javascript to use Visual Javascript though.
It doesn't. Well, Airtable is a database tool which can have apps built on top of as well, whereas Visual Javascript really is to build apps on top of enterprise APIs and databases. It must be noted that every Visual Javascript application does have a built in SQLite database as well.
Anvil uses Python to build apps whereas Visual Javascript uses Javascript. But Anvil is very good, and supports Javascript now, so try it!
Mendix is a commercial low code product owned by Siemens, and is a very different thing since it is closed source.
Outsystems is a commercial low code product and is a very different thing since it is closed source
Node Red is a very intuitive system to process events and actions by linking nodes together. It has a different use case than Visual Javascript as Node Red is mostly used for IoT applications.
Huginn is a very intuitive personal task handler. Visual Javascript is more for applications that need user interaction.
IFTTT is a paid web only SAAS task automator. Visual Javascript is more for applications that need user interaction.
Zapier is a paid web only SAAS task automator. Visual Javascript is more for applications that need user interaction.
Autocode is great cross platform event handler. It is very text based and aims to link systems together. Visual Javascript is more for applications that need user interaction.
Delphi was a desktop IDE from the 1990s using Pascal as the programming language, and had a great set of controls and was even VBX (Visual Basic Custom Controls) compatible. Some people use Deplhi today for desktop Windows apps, and it is definitely one of the inspirations for Visual Javascript. Delphi used Pascal as the language and Visual Javascript uses Javascript.
Dynamic Land has been a big inspiration for Visual Javascript in that we think that the model Dynamic Land uses, of spatial computing will be the future, hence the built-in VR in Visual Javascript. We see a future where the Visual Javascript editor could be used in a spatial way with VR to build programs.
As of June 2021 Bubble is a paid hosted web app builder and is good for building a public facing website. Bubble is excellenet for build your low code startup's public facing site, so it is a different market space than Visual Javascript.
DeFi is more a concept than a single product, but Visual Javascript takes many inspirations from Blockchain and DeFi projects. We have considered how we could run Visual Javascript as a series of nodes, much like DFinity and the Internet Computer.
Yes, but only one. A SQlite native module is used. Everything else is pure Javascript. The reason for this is that Sqlite works almost everywhere. For all other components we like to keep everything as pure Javascript. This often means that we limit ourselves to which third party libraries that we can use. When exporting a Viual Javascript application as a HTML file we use SQLite compiled to Webassembly/Javascript so no native modules are needed.
Visual Javascript breaks down all problems into single files, each of which contains a single Javascript function, which acts as a component. A component can call other components as well if needed to form larger programs.
Visual Javascript has been tested with Kubernetes, OpenShift, and Docker. We will test with more versions, including Rancher as time goes by, but it should work fine with VMWare PKS, GCP, and other Kubernetes distributions
The Scheduler is a NodeJS process which decides which worker process to send a server task to. Each process takes about 40MB of RAM and the default number of these "virtual processors" is 6.
Visual Javascript processes communicate using IPC (Inter Process Communication) via NodeJS
A component is the basic unit of code in Visual Javascript, represented as a function in a .vjs text file
No deep AI yet, but AI is planned for machine vision and learning algorithms. Also AI may be used to match component inputs and outputs and for intelligent code completion in the IDE. We do currently use TensorFlow for computer vision but we don't consider this real AI
Visual Javascript runs all server components in their own child NodeJS process, so if a component goes bad then Visual Javascript will restart kill the NodeJS process, restart a new NodeJS process, and return an error code to the caller
Yes! One of the great things about Visual Javascript is that it works offline without an internet connection
Visual Javascript removes the complexity of separate version control systems like git. Changes to your code are structured using distributed diff algorithms
You need to save the apps that you wish to keep by pessing the button "Save as .vjs file" in the editor
Visual Javascript's basic file format is text, so you can use any editor, but your programs will have to be imported into Visual Javascript if you wish to use the interactive editor
No
No. Visual Javascript only run apps written in Visual Javascript itself as .vjs files
No. Visual Javascript apps can only use .vjs components
It is under development at the moment, but the code is here in this Git Repository for components
The extension is ".vjs" but you can also use the ".js" extension for loading some simple Javascript apps
Zubair Quraishi is the main developer. There are also other people who also help out from time to time, including people from Google, Microsoft, and other companies.
No, we don't need money as Yazz has been sponsoring the development of the Visual Javascript tool. We would only consider investment from the outside if it was a very long term partnership, as Yazz is expecting to be unprofitable for many years to come. We have been approached by many investors to invest in us, but we would only consider long term investors who would also bring some strategic value to Yazz/Visual Javascript.
I want to write libraries for Visual Javascript - how can I take part in the Visual Javascript community/ecosystem?
We will be releasing developer guidelines soon
