VisualWorks: Overview

Cincom® VisualWorks® is a pure, object-oriented application development suite for software developers who need to build applications quickly and efficiently.
Cincom VisualWorks Environment The VisualWorks suite is the premiere Smalltalk environment and has an unrivaled live development environment that is highly effective and productive.
VisualWorks is instantly portable across a wide range of platforms including:
  • Windows (7, 8, 10)
  • Windows Server (2008, 2012)
  • Mac OSX (10.8.x – 10.11.x)
  • Linux (x86/SPARC/PPC)
  • AIX (6, 7)
  • Solaris (SPARC)
VisualWorks has 64-bit engines and images available on:
  • Windows (7, 8, 10) 64-bit
  • Windows Server (2008, 2012R2) 64-bit
  • Linux (x86-64)
  • Solaris (SPARC)
  • New! Revamped code editor
  • New! Editor theme system

  • MatriX multi-core support
  • Internationalization
  • SiouX Web server
  • AppeX Web development
  • Seaside Web framework
  • Web services
  • COM ActiveX
  • Security protocols
  • Distributed protocols
  • OpenTalk
  • Xtreams next generation streaming
Web Services
VisualWorks has full support for SOAP and WSDL. This allows for full interoperability with .NETbased services and J2EE Web services. Wizards make it easy to either expose existing interfaces as a Web service or to create client Smalltalk interfaces to existing services.
VisualWorks provides 64-bit VMs on most of our platforms including Windows 64-bit. 64-bit solutions have a much larger addressable memory, allowing a much larger object space, very large collections and other optimizations for 64-bit.
Source Code Management
VisualWorks offers a sophisticated source management system optimized for Smalltalk and built on industry-standard relational databases. This optimizes managing development for both the individual and the team.
MatriX Multi-Core
VisualWorks lets you leverage multi-core processors with the MatriX framework. Using this can dramatically increase throughput for some applications.
Web Solutions
Cincom supports several choices for developing simple to sophisticated Web-based solutions using our SiouX and AppeX frameworks to supporting industry solutions like Seaside and Amber.
SiouX is our unified, flexible, scalable, highperformance HTTP server. It can support many Web solutions with one capable server, even simultaneously.
AppeX is our lightweight, flexible, nextgeneration Web app framework supporting:
  • HTML5
  • JSON
  • JavaScript
  • XHR
  • Ajax
  • WebSockets
The Seaside Web framework is a highly regarded mature and capable solution for Web-based solutions.
VisualWorks Project Manager
The Project Manager allows easy location and launching of projects as well as new project creation.
Refactoring Browser
The refactoring browser has been getting incremental visual and functional improvements every cycle, and is often where new improvements are first integrated and proven.
GUI Tools
The Cairo graphics package is an option with available libraries, allowing powerful graphic techniques for attractive applications. The user interface operates with multiple processes instead of a single “distinguished” process, enabling more responsive applications. Shortcut keys are industry standard where applicable.
VisualWorks includes an extensive locale system based upon CLDR (Unicode Consortium’s Common Locale Data Repository) locales. VisualWorks now supports bi-directional content for sophisticated internationalization solutions.
VisualWorks supports connectivity to all major relational databases including Oracle, Sybase, SQL Server, PostgreSQL, MySQL, DB/2 and SQLite. VisualWorks also connects easily with OODBMS systems.
Network Connectivity
VisualWorks has an extensive library of internet connectivity tools. We support a variety of protocols including FTP, HTTP, SMTP, IMAP and POP3, supported by a robust MIME framework.
Web Applications
VisualWorks has the new SiouX Web server with goals of performance and scalability, and the AppeX Web framework to build and maintain state-of-the-art Web applications for browsers and mobile devices.
VisualWorks includes an extensive security library including TLS/SSL/HTTPS and mutual authentication.
VisualWorks has an active community that shares solutions. See the public repository and contributed page for available solutions. See
An extensive security library includes implementation of a number of cryptographic algorithms (MD5, SHA, DES, AES, RSA, DSA, DH, etc.) as well as higher-level mechanisms like password-based cryptography (PKCS#5), standard secure private key storage (PKCS#8) or public key certificates (X.509). Many of these standards are supported by a flexible ASN.1 marshaling framework. A complete implementation of SSL protocol is used to secure other protocols like HTTP (HTTPS) or various mail protocols.
The Added Value of ObjectStudio
With ObjectStudio now based on the Cincom Smalltalk Foundation, this powerful combination allows users to leverage the range of VisualWorks capabilities and the state-of-the-art ObjectStudio features. VisualWorks users now have access to ObjectStudio tools such as the modeling tool for architecting applications and the mapping tool for advanced object-relational mapping. Additionally, VisualWorks users can use ObjectStudio for its native Windows GUI.
