What the users say...

"I have just inherited some very buggy code, and the first day I used Visustin, I solved some very complex bugs, what a timesaver."

J.D.

"Visustin saved me enormous time and allowed me to analyze millions of lines of source code with increased confidence. Your product was invaluable to me as confirmation of logic flow and as a graphical representation of such logic flow in both Visustin charts and also Visio."

Jim Keohane, president
Multi-Platforms, Inc.

"Visustin is the greatest!! Makes debugging enjoyable!! Keep up the great work!"

Dallan Lax

"Thanks for the tool. It is great and will save me at least 100 - 120 hours just on my current project which is to document the flow of our accounting applications."

Ron Nooner
Idaho Department of Labor

Spontaneous, authentic comments by real users.

Independent reviews

"Visustin is an ideal tool if you update (or create) design documentation after you write your code. It can also be a great tool if you're a support programmer, because it does an effective job of diagramming complex code."

Visual Studio Magazine 09/03

"It's very cool and I can definitely see where it would be useful in figuring out new pieces or 'inherited' pieces of code."

Visustin for software developers. Visustin is an automated flowcharter for software developers and document writers. Save documentation efforts with automatic code visualization. Visustin reverse engineers your source code into flow charts or UML Activity Diagrams. Visustin reads the if and else statements, loops and jumps and builds a diagram — fully automated. No manual drawing is required. Visustin flowcharts Ada, ASP, assembler, BASIC, C/C++, C#, Clipper, COBOL, ColdFusion, Fortran, Java, JSP, JavaScript, LotusScript, Pascal/Delphi, Perl, PHP, PL/SQL, PowerScript, PureBasic, Python, QuickBASIC, REALbasic, T-SQL, VB, VBA, VB.NET, Visual FoxPro or XSLT.

Visustin for software designers. In addition to visualizing existing code, Visustin helps you design new code. Draw flow charts to plan your algorithms before you write the program.

Visustin for everyone. Not just programmers, but anyone can draw flow charts with Visustin. Document your business processes. Visualize the decisions and tasks your organization has to make. Plan your systems and projects to improve how your organization works.

Why flow charts? Flow charts help you understand complex systems. Fix bugs and write improvements faster than ever before. Review and debug algorithms. Verify program logic. Document complex functions. Restructure incomprehensible code.

Features

Flowchart code automatically. Visustin converts source code to flow charts automatically. An automated layout ensures visually optimal results. Just hit a key and you're done. The charts visualize your code and optionally the comments as well.

Edit flow charts. Visustin Editor lets you edit the automatically created charts. Insert comments, add shapes, highlight important points, adjust links, fine-tune the layout. [Pro Edition]

Draw flow charts manually. Visustin Editor lets you draw flow charts from scratch with the mouse. Document your business processes. Plan your systems before building them. [Pro Edition]

UML. Prefer UML style? No problem! Visustin supports both flow charts and UML Activity Diagrams.

Multi-page print. Print large flow charts as a multi-page mosaic, or squeeze to fit on one sheet.

Save charts. Use flow graphs in your project documentation. Save files in BMP, GIF, JPEG, PBM, PCX, PGM, PNG, PPM, TGA, TIFF, EMF, WMF or PS format.

Export to Visio. Save your drawing efforts. Convert your source code to Microsoft Visio diagrams. More about Visio export Popup link [Pro Edition]

Export to PowerPoint and Word. Create flow chart slide shows and documents.

Publish online. Save flow charts as web pages or MHT web archives.

Bulk charting. Flowchart all your source files in one run. Create Visio .vsd files. Run flowchart jobs in a batch. Add automated flowcharting as a part of your application's build process. Keep your technical documents updated every night. [Pro Edition]

Evaluation service. Saving the flow chart and Visio export are disabled in the free demo. To evaluate the Save or Visio features, send your code snippet to us. We will save the chart for you. Just tell us which image format (or Visio format) you would prefer. We can also save as PDF for you to print.
