Below is what some people are saying about Structure101. You may also be interested in our customers and partners.
Tools exist for enforcing your architecture. Start today! No more "Word architectures"!
Magnus Robertsson,
Our developers are realizing the value of Structure101. One good recent example - five teams started development simultaneously. After two months they realized that one team was developing much faster than the others. That team had deliberately used Structure101 from the beginning and that really paid off in terms of speed.
Anders Goransson,
The initial licenses are in fact a first step for a larger roll out of this amazingly useful and powerful product, Structure101 reduced the overall schedule of one of our projects from 6 months to 3-4 weeks.
Dr. Frank Griffel,
Controlling your architecture is no rocket science
My other favourite was Controlling Your Architecture with Magnus Robertsson from Jayway. What he shared wasn't rocket science, it was something a lot more basic and a hell of a lot more useful. He started off with asking the gathered crowd if they were using architectural rules and how they were applying them. The rest of the talk was spent on the hows and whys to keeping code complexity at a minimum (zero anyone?). The highlight for me was probably Structure101 which instantly gives an overview of project-cross dependenices and code complexity.
Leonard Axelsson,
We view code structural analysis and architecture control as core to building
extensible and maintainable software, and Structure101 just makes this easy.
Sergey Dmitriev,
I was using IDEA and Eclipse to analyze the dependencies in my code. However, I now use Structure101 because it has way more in this area, all wrapped in an easy-to-use and understand interface.
Igor Spasic,
I use Structure101 when I want to understand the overall structure of a system and
evaluate potential changes. I appreciate its breadth, usability, and performance.
Kent Beck,
We have been using Structure101 for more than a year now and there is no doubt it has helped us maintain the high quality of our architecture.
Adrian Colyer,
Playing with a new version of #structure101 - love it for cleaning an architecture
[One of Codemonkey's many tweets. Thanks, Stephan!]
Code Monkey
When you are busy implementing new features it’s easy for cyclic package dependencies to creep
into the application. With Structure101 it was straightforward to identify the cycles and fix them.
Chris Richardson,
Structure101 blew me away! I can't begin to tell you how many 'aha!'
moments I was having ... everything from the cool way code trees are
grouped into "partitions", to the various slices through the code,
to the matrix view.
Enterprise Architect,
The guys at headwaysoftware.com are awesome; how many companies mail you back on a Saturday?
[One of Bill's many tweets. Thanks, Bill!]
Bill de hOra,
We chose Structure101 because of its rich feature set, it's unchallenged cost-benefit-ratio and last but least because of the great support during the evaluation phase.
Soren Kress,
I find that the architecture diagrams are extremely useful for understanding a large codebase very quickly. It often unnerves the people I deal with at the bank -- they'll send me the code expecting me to take a couple of days to get to grips with the basic parts, and I will ring them up 30 minutes later discussing how they need to fix the code up.
I've used Structure101 for a couple of years now, and found it to be fantastic for getting a very good (and fast) overview of large systems. The architecture diagrams in particular show the automatic layering of 500kloc systems well.
The micro-architectural stuff (packages and classes) is also well catered for with the dependency diagrams. Worth its weight in gold.
Andrew McVeigh,
There's been a need for a product like Structure101 for a very long time.
The ability you have to click through and navigate up and down the structure of
the code base is both eye opening and addictive.
I found the online Flash tutorials great to not only get familiar with the Structure101 concepts, but also to see some of the intent for how its designers envision it being used.
Derek Lane,
Structure101 is a great product and I've found it very useful when refactoring our codebase. It doesn't try to do too much or swamp you with features - just does what it says, cleanly and efficiently.
Luke Taylor,
This fragility in the code structure would likely have caused a maintenance overhead as Spring Security evolved, so the decision was made to restructure the code for the 3.0 release to give us a stable base for future development.
Luke Taylor,
Structure101 has proved invaluable... It has excellent support for analysing the dependencies between components and identifying anomalous dependencies. I've really appreciated the support from the Structure101 developers who have helped me get the best out of the tool.
Glyn Normington,
I've been extremely impressed with Structure101. I haven't been blown away by a Java application in a very long long time ... Structure101 blew me away!
Scott Miller,
Structure101 (for .Net) rocks! Want to understand the structure of your app? Structure101 should be your first choice.
Tweeting on the early access release of Structure101 for .Net. Thanks, Torbjorn!
Torbjorn Gyllebring,
Structure101 is indispensable for understanding a system's architecture. In addition to providing great, simple code metrics, it excels at providing an intuitive way to visualize and navigate dependencies from major subsystems down to classes that is unmatched by any other tool we have used.
Structure101 has helped us dramatically improve our design by highlighting where we needed to remove bad or unnecessary coupling.
Jim Marino,
Structure101 analyzes codebases to elicit the kind of information that good
developers hold in their head for small projects, great ones juggle for large
projects, and only the likes of Richard Stallman and Bill Joy can master for
enterprise-scale projects.
Rick Wayne,
Teaching software architecture to students is difficult, IDEs like Eclipse only show class level details, and UML tools like Poseidon only show the desired structure at design time. Structure101 allows me to make visible what the students can't see otherwise and makes for an impressive learning experience. Especially the architecture diagrams which stick in the mind and get the user thinking in layers. I strongly recommend S101 for teaching purposes.
Marko Boger,
I, as a Fornax cartridge developer for the oAW code generation framework, naturally want to see if the generated code is well structured.
Structure101 is just the right tool to see results in a snap. It is an easy to use, easy-to-understand code analyzer.
No matter how big your code base is - with the help of this great tool - you can always check if you are going in the right direction.
A perfect tool that just gets the job done, keep up the superb work!
Attila Bak,
We have been using Structure101 on Junit and are very happy with the way it helps us keep the Junit architecture under control.
David Saff,
Your customer support is on par with your software, I love both!
Fredrik Olsson,
I refactored a UI and application framework for JavaME, which had 45% XS when I started. It is now down to 0% and many bugs just magically disappeared. I would say that Structure101 was indispensable for this task.
Fredrik Olsson,
Structure 101, the best tool I have found to get an overview of your system design/architecture.
Jarle Hansen
I would like to tell you that Structure101 is just what I needed!
Claus Krog Jensen,
With 2 big projects, over 50 developers and millions of lines of code,
we were fighting with what we call jar-cancer, almost blindly using refactorings.
Structure101 is an X-ray device that allows us to identify dangerous cross-module
calls ahead of time and helps us find solutions quickly. More...
Balazs Fejes,
I evaluated several alternatives, however Structure101 is truly superior in terms of performance and usability: it will be my privilege to use it.
Alessio Tomasino
@jridley I found this article by Structure101 absolutely fascinating. What an incredible tool. http://bit.ly/eEhys
Brandon Hornseth
I loaded our application code and in a matter of minutes I was blown away by the
simplicity and the power of Structure101 to analyze the organization and design
of your code.
Emilio Suarez
I love the architecture diagram functionality. With it we are able to define
our architecture standards and enforce them during design and construction. As a
Chief Architect who is responsible for overall design and system architecture, this
capability is a great value-added to an already fantastic product.
Joong Lee,
Overall, a nice piece of work to keep control of complexity. [...] A seriously amazing product!
Chris Rimmer,
After evaluating all of the open source code complexity analysis tools,
I found Structure101. Within a few minutes I could see the difference,
seeing exactly where my cyclic package dependencies were, drilling down,
and identifying the offending methods and classes. Simple as that.
David Moshal,
Structure101 is fantastic! In a matter of minutes, you can pinpoint the packaging
and dependency issues in your application. The ability to move Java classes around
on-the-fly helps jump start refactoring exercises. If you're an architect working
on an system of any size, Structure101 greatly simplifies controlling the integrity
of your application.
Jim Majure,
I downloaded Structure101 a few days ago and used it to analyze complex
applications that I am working on. I found the tool very intuitive, easy
to use and insightful. The Structure Guys did an awesome job!
Alex Iskold,
We have used Structure101 for several years to ensure continuous architectural
quality of the Java portion of our flagship application, LeaseAccelerator,
despite rapid growth in features and functionality. With the release of
Structure101g, we are now able to extend this quality process to our SQL
and Javascript, ensuring proper partitioning and separation of concerns
across all layers, regardless of implementation language.
Software evolution and maintenance are the purest forms of code entropy;
with Headway's Structure101 products, we keep the creeping chaos at bay.
Jonathan Crawford,
Headway provides a powerful way for programmers to visualize, understand, and
address the OO code spider-web complexity problem head-on. This is easily the
best software I have seen for this purpose.
Robert Babb,
Even in the short amount of time I've been able to spend learning Structure101
since downloading yesterday, I've already been able to gain tremendous insight
about a number of my own large codebases. In a lot of ways, this program seems
to be something I've been looking for literally for years.
Ryan Barnard,
Amazing tool. After every milestone I check my architecture with Structure101
and almost always I need to do refactoring after that.
Nemanja Kostic
I am a freelance Java developer and team lead with many different clients. I need
to familiarize myslef with the client's code bases in a really short time. I found
myself constantly returning to Structure101 for that job. A few minutes with
Structure101 shows me the architecture of the code and highlights the problem
areas. So, finally, it seemed only fair to become a customer.
Kees Jan Koster
Structure101 has proved to be an outstanding product. It is particularly strong in
reinforcing key packaging principles and its design lends itself very well to iterative
development and extensive refactoring cycles. More...
Eamonn de Leaster,
I just bought a license for Structure101 today, it just does exactly what I was looking for.
Stephen Magee,
Structure101 has a very effective, simple and intuitive interface. It has proved
itself a great product at Readers Digest to help us understand and address design
issues in our increasingly large systems.
Andre Carron,
I am a Java consultant, and Structure101 is one of the coolest tools I have ever seen.
I have been wanting something like for this for a long time.
Seba Jean-Baptiste
Structure101 is definitely a great product, it makes it so much easier to describe and explain architectures to outsiders or team members.
Robin Gallimard,
I'm absolutely impressed with Structure101, I only wish I found it a long time ago. Thanks for the tutorials, you guys managed to make these complicated concepts look easy.
I spent the last three weeks full time doing high-level refactoring and solving tangles. I did all of that with the Eclipse plugin "Metrics", with Structure101 I'm sure I would have done the same thing in one week.
Diego Moriarty,
Structure101 helped me get rid of some elusive thread-locking problems while allowing me to zero in and clean up the most poorly architected parts of our code.
Leendert Visscher,
Avantia, Inc. specializes in performing audits for clients with complex software systems.
Avantia was able to replace six different software analysis tools with Headway. Headway
also assisted by decreasing the time needed to generate analysis output from weeks to days.
Jeff Ladd,
Structure101 is exactly what a J2EE architect needs to audit the deployed system during
development to catch nasty dependencies and take steps to put them right.
Mike Swainston-Rainford,
This is one of our most successful projects at Rolfe and Nolan. We were constrained by budget but Headway has enabled us to deliver more with less, and most importantly without any compromise in quality.
Phil Reed,
As a busy engineering manager, running multiple projects, I don't have time to do
deep dives into the code. Structure101 gives me all the information I need about
the integrity of the codebase at the touch of a button.
Paddy Benson,
Structure101 is such a simple product to use and very affordable. I would say it's
well suited to software practitioners who care about software quality. Everyone who
writes code should be reviewing their code structure, at least on a weekly basis.
Malcom Sparks,
The case for modularity in software is growing stronger by the year. Initiatives such
as OSGi and JSR 277 are driving a demand for modular software architectures. In spite of
this, today's large Java code-bases are a tangled web of spaghetti, hopelessly resistant
to modernization. If you want to modularize an existing code-base, you'll need Structure101.
No other tool, open-source or commercial, comes close. Thoroughly recommended.
Malcom Sparks,
You guys have a kick-ass app. Whether I qualify for an open source license or not, I'm going to
strongly recommend it anywhere folks need to understand and clean up large code bases.
Morgan Schweers,
We are very impressed with the latest release of Structure101. It has allowed us to improve the quality of the architecture reviews we do for our clients, but most importantly for them and us we have been able to achieve this in a shorter time frame.
Alef Arendsen,
My company has decided to start by buying a few licenses but I am sure more will follow since all developers I have demonstrated it to want it. I think it is the best developer tool I have seen since I found IDEA some 5 years ago.
Olle Sunblad,
I used Structure101 in several open source projects in my graduate research. It’s been instrumental - from helping me to refactor complex software using design patterns to generating interesting metrics and models that visualize my code. These features only scratch the surface and I will consider Structure101 a must-have when working with Java software in the future.
Geoff Scholl,
I demonstrated Structure101 to the students of my software engineering course. They then did a lab with it.
Cool tool, students liked it too! Now I will continue to use Structure101.
Prof. Hans Rudin,
Using Structure101 when performing code and architecture reviews is a real kick-start for our consultants.
We can very quickly get a comprehensive overview of the structure of an application or framework and of its
quality. With Structure101 in our toolbox we can help clients analyse and refactor their code-base into a
consistent architecture with decreasing dependencies and better distribution of responsibilities. After such
an activity, clients find their code-base easier and more cost efficient to maintain, change and enhance.
Björn Granvik,
Headway provides excellent products for finding architectural flaws, particularly
those that result from the evolution of large complex systems.
James Gosling,
I would argue against using the term 'reverse engineering' for Headway . To me,
reverse engineering is salvaging some sort of design from code. What Headway offers
in my opinion is a visualization of the code itself. It just so happens to use
reverse engineering techniques to achieve this - however this is arguably an
implementation detail. UML reverse engineering 'may' offer to help discover the
intent of the original designer, whereas Headway tells it like it is i.e. it
provides an implementation view rather than merely an abstract design model.
Jason Chambers,
Gaining a deep knowledge of the real architecture of customers' code is crucial
when delivering quality consulting solutions. Headway provides a dynamic,
graphical view of the structure of large systems. There is no easier way to
reduce the time required to manage a changing code base.
Paul Scott-Murphy,
In addition to helping us componentize and continually improve our code base, Headway also helps out our developers in writing new code. Several developers use Headway on a daily basis to check their work for patterns that might turn into maintenance problems down the road. This has been a big boon to productivity, and has helped even some of our top developers improve their coding.
Matt Mihic,
Using Headway on the repackaging project it took me two or three days to learn the codebase, determine the correct layering and discover all the code required to fix broken dependencies. Without such a product I would guess the job would have taken at least 3 weeks.
Alan Conway,
We purchased from Headway to reduce development costs and found that
the tool improves developer productivity when doing code analysis by
up to 50%. It also shortens the learning curve for new team members.
Klaus Beschorner,
Our initial purchase decision was based on reducing our development costs, but since we started using Headway more extensively we've found that it has improved the quality of our code. It is often difficult to quantify such benefits, but it's clear to all of us at DAT that they are substantial.
Uwe Dengler,
Using Headway I can quickly and easily check that our developers are
accurately implementing the product design thereby ensuring the timely
delivery of product to market. After only a few months of using Headway's
product I am confident that our initial investment will save us man-years
of effort in our ongoing product development. In my opinion Headway provides
'must have' products.
