Test Driving the Quplo Preview

What Quplo Is

Quplo (pronounced “CUE-plo”) is a Web prototyping tool that fits in a niche somewhere between pure visual design and building your app.  It’s completely Web-based and requires no downloads, and the results can be viewed instantly.

What It’s Not

Just to be clear, Quplo is not a Balsamiq Mockups clone, nor does it try to be.  The emphasis is on interactive prototypes and not static images.  Unlike Balsamiq, Mockingbird, or Microsoft SketchFlow, Quplo has no drag-and-drop graphical designer.  At its core is a syntax-highlighting text editor that supports HTML 5, CSS, and Quplo’s own built-in language.  Quplo complements, rather than competes with, wireframe drawing tools.

Similarly, Quplo doesn’t generate wireframes in the rough, handwritten style commonly seen in prototyping.  As such, it does nothing to protect you from the false perception of completeness that customers and nontechnical managers may have when viewing your prototypes — you’ll have to deal with that yourself.  On the other hand, it gives you complete control over your prototype’s interface and behavior.

User Interface

The UI is intentionally sparse, with little more than the editor itself on the left and a syntax reference list on the right.  One nice touch is that the editor can be expanded to fill the browser window, which maximizes screen real estate when writing markup.  Presentation is clean and easy on the eyes, with soft-looking gradients throughout the site.

Compatibility and Performance

I tested Quplo in Firefox 3.6.3 on Windows 7 and XP.  Performance was good in both operating systems.  I did notice a bit of choppiness scrolling in the text editor at times, but it had no effect on the overall experience.

When I attempted to view the site in Internet Explorer, I got a rather humorous surprise:

Quplo in IE

I’m certainly no IE fan, but I’m not sure how I feel about this.  At least it fails gracefully.

Update:  Martin Kool from Quplo commented to explain the rationale behind not supporting IE at this stage, and that it will be supported before they go live.

Rich Editing Functionality

The online editor is slick and carefully tailored for editing markup.  Line numbers are shown by default.  Syntax highlighting and auto-completion are fast and don’t interfere with typing.

Quplo’s Built-In Language

Quplo supports a tag-based language that’s an unusual hybrid of declarative tags and imperative actions.  It offers simple functionality like looping, variables, and conditionals, but perhaps more importantly, it also lets you reuse sections of markup with a templating system consisting of “layouts” and “parts”.

Subscription Model

Quplo is available on a monthly subscription basis under a number of plans.  Plans vary in storage space, maximum number of users, number of prototypes, and several other bullet-point features.  Daily backups and export capability are part of each plan.  Closing your account deletes your prototypes, so make sure to export copies if you decide to end your subscription.


The people at Quplo are extremely helpful and responsive when it comes to questions, and they’re active on Twitter, email, and their own blog.


Quplo is a promising new prototyping tool that’s currently in beta.  While most of the functionality could probably be substituted with a combination of other tools (offline text editor, JavaScript, server- or client-side includes, Google docs, etc.), Quplo distills everything you need to build interactive prototypes into a single, easy-to-use online service.  I’m considering integrating Quplo into my design workflow for my next project, and I look forward to the initial release.

  1. Hey Andy,

    You really narrowed it down to what we’re trying to achieve with Quplo. Thanks.

    As we’re still in beta put our mind to Chrome, Firefox and Safari, which was all about priorities and being able to use the best tools (html5, css3) for the job. So yes, we haven’t focused on Internet Explorer support but we won’t forget IE once we go live.

    We could’ve put up a more subtle “not supported yet” page up, but at least this made you grin 😉

  2. so this is just a syntax highlighter for html, i do not see the value proposition, or even what differeniates this from dream weaver?

    1. Brian,

      I understand your point — I had a similar first impression when I started using it. The main thing is that Quplo sacrifices power for simplicity — Dreamweaver is a Web development tool, while Quplo is for building prototypes. Also, the pricing model is different. Paying for a monthly subscription may be more palatable to freelancers, for example, than buying Dreamweaver licenses outright. Finally, Quplo is Web-based. You can easily collaborate with others to build prototypes from anywhere, the files are hosted on their servers, and you don’t have to install anything.
