JIMMIE SHAHAN - licensed RealThinClient user since March 2006.

I work for a small application provider that allows me to work from my home. In addition to my programming duties I also do phone support. Having the RTC components for Delphi has allowed me to write a small custom host application for my clients that has a single button on it's form to connect to my computer. Then I can remotely view and troubleshoot on their computer. The RTC code seems faster than shrink wrapped solutions I have tried and the simplicity of the one button application for my users makes it a dream come true to use.

TED ROPER - licensed RealThinClient SDK user since June 2007.

Thanks to your RTC SDK component set, I was able to add a reliable Web Server to my application. My customers have been requesting real time web monitoring and control of their radio telemetry systems. With your components the task became doable. I have been running my application with your web server for several months now without a hiccup. My customers are also running your web server and they love it. It's great to use a product that works well.

Thanks for a great product.

STEVE KALHAS - licensed RealThinClient SDK user since September 2006.

Using the RTC components, I wrote a robust and agile web server in less time that it would have taken me just to learn how to configure any of the free or not-so-free web servers. Multi-threading/sessions/cookies/etc. are being taken care off by the RTC component so all I have to do is write C++ code to handle each request and send back a file or HTML code.

I wrote three different servers so far and they all have been running for over a year with no problems at all (and with a small footprint). I also laugh when I see in the logs attempts at cracking the server. Those attempts are exploring weaknesses of well known servers (Apache/Microsoft/php/etc.) and since I'm not using any of those, I do not have to worry.

My servers do not have many configuration options so there are no things that I forgot to set. It took me no time at all to blacklist a user who was trying to guess passwords. In short, the RTC tools are very flexible and my three servers are running on the same Windows 2003 server under different IP addresses. Feel free to try out the main server at "http://www.Webium.com".

STEVE GILL - licensed RealThinClient SDK user since March 2006.

Although I have only been using the Real Thin Client SDK for a few short months, they have already become invaluable and essential to the applications I have been developing. They have reduced development time substantially and proven to be robust, solid and fast.

After having written ISAPI applications for years using WebBroker, I can't believe how much easier and quicker it is to develop this type of application using RTC. As a test, I redeveloped my WebBroker-based ISAPI applications using RTC and noticed a significant improvement in response times.

RTC is very versatile and can be used for a lot more than just ISAPI applications. I'm sure I've only explored a new small portion of its capabilities so far. I'm really looking forward to the new features Danijel and co have planned for this excellent framework.

MANFREDT KAVETU - RealThinClient SDK Open Source user

I would like to tell you you have become my hero. I dowloaded your GPL open source components and did a thourough stress test using your demos. The demos are commercial quality and very solid and one has absolute confidence when working with RTC components. Previously I tested other MW components like Dbovernet, Asta, KBMMW, and Remobjects, but did not commit to any of them.

We are 100% sold to RTC components and we have decided to fully use RTC components as our middleware solution for our hospital information management system.

GÜNTER KIENINGER - licensed RealThinClient SDK user since August 2006.

Mit den RTC SDK Tools war es uns möglich, unsere Anwendung innerhalb weniger Tage so zu erweitern, daß langwierige Programmaufgaben auf einen Server ausgelagert werden können, ohne daß die Benutzer die Kontrolle darüber von der Clientseite aus verlieren. Der Support und die Hilfe von Danijel Tkalcec war schnell, ausführlich und äußerst kompetent.

DAVID GUEST - licensed RealThinClient SDK user since June 2006.

I am delighted with the success I have had with the RTC components.

With no prior knowledge of isapi or internet requirements other than some very basic html, I was able to develop and install an intranet server and website which provides reports from a number of NexusDB database applications as well as a forum for my users to access to ask questions or make suggestions, with less than a week's learning and effort.

I know of no other product which would allow me to do this with the same ease, speed and degree of confidence. I found that even the demos are of commercial quality. RTC is an outstanding software company with rapid, very good support.

CHRISTOPHER FIELDHOUSE - licensed RealThinClient SDK user since June 2006.

Can I just say how pleased I am with the SDK, my old webservice (that is now replaced by the RTC server) used to take about 4-5 seconds to return the data, the new RTC Server does this in under 2 seconds and doesn't hang my app while it's waiting. Add to this that I got all this working in one day! Well done.

KEITH BLOWS - licensed RealThinClient SDK user since December 2005.

I own three other very popular Delphi remoting component sets, which I have never been able to implement successfully. I have quickly been overcome either by the limitations in what they can transfer, or by their technical complexity. With RTC SDK, I have yet to run into either of these problems. I am a very happy RTC SDK user since December 2005.

Once I became accustomed to the non-blocking nature of the component set, I was quickly able to build RTC servers and clients with great ease. By simply setting a single property, ZLib compression is enabled. By setting two properties, basic encryption is enabled.

My first RTC SDK remoting solution, a challenging multi-master, field-level database synchronization system took me close on seven days to write. My second solution, a XML/SQL query server, took 4 hours to write and my third solution, less than an hour. These RTC servers and RTC clients run 24/7, without a single hitch.

For me, the greatest triumph of the RTC SDK is the ease with which I can transfer *any* Delphi data type with just a few lines of code. No other remoting library offers this kind of flexibility, without sacrificing speed or reliability.

However, without technical support, a great product alone is not enough. In my first two weeks getting to grips with RTC's nuances, I got detailed, informative e-mail responses to my questions from RTC support within minutes. Overall, I'm simply blown away by the whole RTC SDK experience.

Extremely good value for money ! - good components, well supported. The best thing about the components is the person behind it. Whenever I have been stuck I have always had prompt replies to my email with helpful instructions, advise and recommendations.

JON P. GREWER - licensed RealThinClient SDK user since June 2005.

I chose RTC components for my web based application because of the simplicity demonstrated on the "Getting started" web pages. Not only are the components easy to use but just about every time I wished for a feature, it was already included.

Any web based Delphi project will benefit from the power and ease of use of the RTC components.

JIM GALLAGHER - licensed RealThinClient SDK user since May 2005.

I'm using RTC components to replace another 3rd party solution for remote functions. I have a client/server type of application with many rich clients talking to a central server. With my previous solution I had problems with updating client applications after updating the server. There was interface code that had to be compiled into the client applications.

RTC lets me avoid that whole upgrade headache. I can upgrade the server application and still have older clients connecting without any problems. I can deploy the updated clients to make use of the new features without worrying about version contention. I'm finding the remote function ability of RTC to be very intuitive and easy to implement -- and extremely stable. Support couldn't get any better. Response time to questions (I haven't found any bugs) is extremely fast.

I highly recommend RTC components, and am excited about the new features previewed in the roadmap.

GERHARD KNAPP - licensed RealThinClient SDK user since February 2005.

Requirements of our customers and the progress in computing defines what we have to develop. Most important requirement is the location independence. In other words, our customers need software they can use on different locations, not only in one LAN (connect locations in Vienna, Berlin, Munich and also use mobile devices). Other requirements are: (a) get same complex functionality as in the classic Client/Server software (rich clients), (b) have same performance, (c) same security and (d) use only one central data store (databases) as the heart of all information.

Our own requirements are: (a) realize the customer needs fast and (b) re-use our existing source code (many man years).

We have searched for new solutions to satisfy this and other requirements. Shortly, it was clear that it should be the HTTP Protocol, a 3-tier web architecture, non-blocking, multithreading, all in Delphi, supporting Wininet (proxy, firewall, etc.) and prepare us for future solutions, when we have to move to .NET or Linux (at this moment, we have no intention to move to .NET or Linux, we develop win32 applications). Our Web application server has to be very fast, very stable and should handle a lot of concurrent connections and remote functions.

One day, we found what we need: RealThinClient components

In the beginning, we had some problems to understand RTC components. But, with excellent support from Danijel Tkalcec (fast, very professional and helpful) and the power and simplicity of RTC, we implemented our remote functions very quickly. RTC offers excellent stability and produces small applications with no memory leaks.

Until today, using RTC, we have realized (1) Clientel Web Application Server with 30 remote functions, the most are database functions with Firebird SQL Database as central data storage (clients using an early RtcDataSetClient beta). This Web Application Server is at the same time a PHP Web Server. (2) RTC Support Messenger is now integrated in the software used by our customers. We tested the Web application server with locations in USA and Europe. All tests was very satisfactory.

There is no big company behind RTC, which could be a problem one day. But ... there is full delphi source code, the support is very good and we can bring in our requirements. This is something we can not expect from big companies like Microsoft or other software giants.

Our wish is to get E-Mail components in RTC, so we can send E-Mails directly from our Web Application Server, without using other third-party components. RTC Forms for Windows, Linux and Mac (maybe windows and java solution) is also one thing we are looking forward to.

Bottom line is ... we are very happy with RealThinClient components and see great future in RTC.
