Was the best until 2009, but then the developers left and it's been rubbish since We are still using vBulletin 3.8 having been a vBulletin customer since 2001. It used to be the market leading software with good reason, but in 2009 the original development team left (all but one) and the replacement coding and management team has been very poor. What was needed in 2009 was a complete rewrite. However vBulletin 4 was vBulletin 3 with code 'updates', and vBulletin 5 connect is vBulletin 4 with code 'updates'. It took years before vBulletin 4 was considered a reasonable forum solution, and vBulletin 5 is truly terrible. Way too many queries and css definitions. Full of bugs just like vB4 was on release. We're migrating away from vBulletin as soon as possible, having seen that vBulletin 5 is not a viable product. In summary. vBulletin used to be the best. Now it's terrible. AVOID.

Top forum software Excellent and clean software. Would highly recommend.

Bug ridden piece of software that will … Bug ridden piece of software that will drive you nuts trying to get it to work. Never get the mobile app add-on as it simply doesn't work at all. I've wasted so much time and energy on this software, a real regret.

Your site, your vb After 9 years running a leading website in my niche (last 5 of them with a vb based forum) I've come to realize that my site would no longer exist if it wasn't because of vBulletin. The decission to include a discussion board in my site, and base it on vb, was the single most important and life-changing choice I made in my entire webmaster career. It's not only that it doesn't lack any feature you'd ever need to admin the busiest site. Not only the unlimited modding and customization power. It's not only the awsome support, the steady rate of new and every time more stable and feature rich releases. It's that vBulletin really gives you the best foundation to build your site arround it as you really really wish.

There is no better for forums There is no better for forums, would like something even better but alas
