We are the head honchos, sole proprietors and smooth operators of Alsjeblaft (est. 2009) & Alsjeblaft, LLC. The three of us have been cranking out web sites for a living since the Dot-com boom.


We're experienced front and back end web developers with a knack for design & typography. We prefer to "Keep it simple, stupid". We focus on speed, accessibility and making sure your site works on every device under the sun, rather than cramming in every latest web fad.

Copy that

Additionally, we can help you with your English and/or Dutch copy by providing copy editing and translation services at competitive rates. Please click here for more information.

Tools of the trade

While building beautiful and responsive web sites, applications & banners, our tools of the trade include (but are not limited to) Photoshop ®, Illustrator ®, HTML, CSS, PHP, MySQL, Textile & jQuery.

We've worked with the APIs of Mailchimp, Mollie & Chainels, built a platform for shopkeepers and created banners that run on bank ATMs.


All our sites proudly run on Jack! Jack – a PHP7-based framework with a user friendly CMS back-end. Jack's been in continuous development since 2009 and is currently serving well over 150 websites!

Fresh produce

We couldn't begin to list every single website we've worked on over the years, but we would like to highlight a few we're particularly proud of.

All our sites, webshops & apps are build on Jack.


Jack is a home-grown Content Management System (CMS) that makes managing your website a breeze. We built Jack because we think you shouldn’t have to be a rocket scientist to run a website.

Jack isn’t particularly demanding either. It runs on Linux, Apache, MySQL & PHP, a software stack which is supported by pretty much every hosting provider under the sun.


Website, shop, blog, or intranet? Nederlands, Français and/or 普通話? You betcha! News archives, shopping carts, sign ups, Instagram feeds, anything is possible. You dream it, we'll build it. Jack’s modular design makes it a viable platform for a plethora of websites. Don't just take our word for it: Jack's currently running on over a hundred servers!


And the best thing? Using Jack is one-hundred percent free! Free to use and modify as you please. No hidden fees or subscription costs, no fine print. You pay us once to design and build your custom website, you get to use Jack for as long as your site is live. Free of charge!
