Which systems are considered to be the market leaders in user numbers, reputation and features in the forum software (as opposed to hosted service) field?

  • I realise this is slightly subjective, but I am looking for a rough top 3 or 4 - rather than an absolute winner. I'm interested in going with the best regarded offering.

  • Guess that makes this community wiki. Don't you think?

phpBB and vBulletin dominate the market.

phpBB is free and open source where as vBulletin costs a couple hundred bucks and is closed source. (but sometimes has a few more features)


3 market leaders in forum software, scale, big clients, in no particular order:

  1. Jive
  2. Lithium
  3. LiveWorld
  • I agree. They, like you said, target companies and enterprises.
