Buy Membership Software and Systems Online, UK

We are a leading online provider of membership systems and software.

Sitelok is our popular online membership software designed to password protect and control access to html or PHP pages within your web site.

Its perfect for membership websites as you can separate your site into multiple members only areas and each user can be a member of one or more areas.

Depending on your membership system requirements new users can be added to Sitelok either manually via the Sitelok control panel, automatically from a membership PHP script using the Sitelok API or via a registration form that allows a user to add themselves. Our Paypal and 2checkout Payment Plugins (free of charge) allow you to sell membership using buy now or subscription buttons also (available for download from the support area after purchase).

Sitelok is packed with features but we also have a range of plugins providing extra features such as Facebook login, OTP token login etc. You can see a brief description of our plugins on the plugin page where you can also download the manuals for further details.

Membership Websites Software

A user’s specified website membership area can be set to expire after a fixed number of days or can be left open. Once setup our website membership software makes securing a page simply a matter of adding a simple code snippet to the top of the page. The Sitelok control panel provides an easy to use and powerful online membership management system with easy ways to manage users, see the access log and adjust the configuration.You can also send template based email to one or more members (with multiple conditions) making Sitelok a powerful way to keep in touch with your members. Sitelok can optionally allow search engines such as Google or Bing to index your members pages while maintaining security. This flexibility can dramatically help with SEO on some sites. More details on this can be found in our Member Management Software FAQ.
We have been very, very happy with both the Sitelok program and the folks over at vibralogix. Sitelok was easy to integrate and the few issues we had (on our side) were promptly resolved by the staff. They really have a "Can Do" attitude there. GREAT PRODUCT, GREAT PRICE, INCREDIBLE SUPPORT. Highly recommended!!!
I am extremely impressed with the quick and effective support offered by VibraLogix. They have helped me get the entire system up and running very quickly. I have never experienced such a level of support on any membership software or indeed any software, regardless of price. I highly recommend this package to anyone who runs membership websites; software like this is a dream to use.
