Forums can be a great way to encourage audience participation, and to change a website from a one dimensional entity into a full fledged community. There are a number of well developed open source forums out there on the web to help you create that, each with their own benefits. This review breaks down some of the best software out there in 2011 with a focus on everything from lightweight forum solutions to the all singing, all dancing heavyweights.

Vanilla

URL: http://vanillaforums.org/

Features URL: http://vanillaforums.org/features/embed-vanilla

License: GPL

Runs on: PHP / MySQL / Postgres

Vanilla has always prided itself on clean underlying code, bringing together web standards, code reuse and css to create a product that kicks lumps out of 1990′s bulletin software that we’ve become accustomed to on the web. With many of the forum software solutions out there on the web carrying a technical burden of tables and bloatware, Vanilla brings with it a fresh approach. With almost half a million communities now being powered by it, the maturity of the product is no longer questionable, and the feature set rivals that of older products – Vanilla now boasts social sign-in integration, full theming support, WordPress integration (via a plugin) and a number of community submitted plugins.

It also works fully on mobile devices, ensuring future compatibility for your site and audience. With the growth of the mobile web, that is sure to be a deal maker for many webmasters, and it’s likely that we see many older communities making the switch. Vanilla have made that process even easier with import plugins at the ready for PHPBB and VBulletin – two dinosaurs in the forum world that should be afraid. Very afraid.

OSQA

URL: http://www.osqa.net/

Features URL: http://www.osqa.net/learn-more/

License: GPL

Runs on: Python / Django Framework

Whilst not technically a ‘forum’ OSQA still could provide a community element to many websites. Essentially it is a fork of CNProg, a Python clone of Stackoverflow, and joins the others (Shapado / Question2Answer / Askbot )  which have tried to mirror it’s success.  It runs on top of the Django web framework, so if you are familiar with developing with it, you should be able to hit the ground running.  Although it does take a bit of messing around with to get installed if you aren’t familiar with Python, if you are looking for a question / answer type site then you could do a whole load worse than looking at OSQA.  It is under active development with the last commit on the project 1st of Feb this year. Awesome, as it looks like it has a real chance of succeeding.

BBPress / BuddyPress

URLhttp://bbpress.org/

Features URL: http://bbpress.org/about/features/

License: GPL

Runs on: PHP / MySQL

If you are looking to use a WordPress plugin to power your forum, then BBPress is by far the best solution on the web today. It is developed by the WordPress team, so you should find the same level of support and help as is available with WordPress. Buddypress, a sister solution which is available to roll your own social network , also offers integrated forums, and the aim for BBPress going forward is to shelve version 1, and roll out a plugin which will be capable of being used across WordPress, WordPress MU, and Buddypress.

This separatation of functionality makes sense, and should help the project grow in stature, tap into the respective development communities of each offshoot project, and enhance the project overall.  As a side note, plugin developer Justin Tadlock has started work on a really interesting plugin project for forums, which uses WordPress custom fields. I for one am staying tuned to see where that project goes.

Simple Press

URL: http://simple-press.com/

Features URL: http://simple-press.com/features/

License: GPL

Runs on: PHP / MySQL

Another forum plugin for WordPress, Simple Press offers some additional functionality and features to those found with BBPress. The frontend and backend code is mostly clean and commented and they’ve added some nice touches with Ajax in some places. They also appear to be ahead of the curve with releases, as activity on the plugin appears to be as recent as this month. Good to see on a product that isn’t a part of the WordPress core. Many of you will find it easy to setup, but probably one of the only things missing is import export functionality, as some people may want to marry up an existing community to run on it.  From what I can see however, that is a feature which is in the pipeline.

Yazd

URL: http://www.forumsoftware.ca/

Features URL: http://www.forumsoftware.ca/features.jsp

License: Apache Software License

Runs on: Java on MySQL / Postgres / Oracle / SQLite

Yazd  is open source and free discussion forum software running on Java, one of the few on the web that I’d come across. It runs on native JDBC for the database interfacing, with no ORM layer such as Hibernate. The project is relatively small, although tightly coded. From what I could see from initial research, there hasn’t been any security issues since 2008, but that is perhaps a reflection in part of its current adoption. That said, if you are looking to get off the ground running, and your other systems currently work in Java, Yazd may be a good starting point.

Mini BB

URL: http://www.minibb.com/

Features URL: http://www.minibb.com/features.html

License: GPL / Link attribution

Runs on: PHP / MySQL

Mini BB prides itself on being small, yet powerful, and recognise that forum software is often bloated. Written in PHP,  it is lightweight in its code generation with CSS and XHTML templates which are W3C compatible, and offers SEO-optimisation through a mod_rewrite module. It includes the common threading and replying options that you have come to expect from forum software and also support a variety of databases, although MySQL is the default.  If you are looking for a lightweight forum, with high performance that has clean and clear code – Mini BB is well worth investigation.

Phorum

URL: http://www.phorum.org/

License: Phorum / BSD type license.

Runs on: PHP / MySQL / Postgres

Whilst a bit low on feature set, Phorum has been designed with high scalability and performance in mind. As testament to the success of this objective, it currently runs the forums over at MySQL – so rest assured that it can cope under heavy load.  With a small feature set, it does do the simple things particularly well, and has a pretty comprehensive module / add-on community that beefs up the core offering.  It has a bespoke templating engine to allow full skinning of the software, and the code is well written and documented. They could do with a helping hand with documentation though – which like many open source projects, leaves alot to be desired.

Simple Machines Forum

URL: http://www.simplemachines.org/

Features URL: http://www.simplemachines.org/about/features.php

License: Custom License

Runs on: PHP / MySQL

Touted as a great alternative to vBulletin (commercial forum software), Simple Machines offers a powerful feature set in a free, no charge, no strings open source box. Although heavier in some places than the other software mentioned here, it has everything you need to successfully integrate a forum with your own website, regardless of your current setup.   Some of you will know the team behind Simple Machines Forum were originally behind YaBB SE – a PHP port of Yabb Bulletin board (which originally ran on Perl). Simple machines is the next incarnation of that successful open source project. Documentation for the project is provided by the community for the community with installation and help and a number of high quality themes have also been developed for use alongside the software. If you are looking for a more feature heavy product, and aren’t prepared to pay the moolah for vBulletin, simple machines is probably your best bet.

FluxBB

URL: http://fluxbb.org/

Features URL: http://fluxbb.org/about/features.html

License: GPL

Runs on: PHP / MySQL / Postgres / SQLite

Another forum to file under ‘light and fluffy’ is FluxBB.  As with Vanilla it produces valid markup and clean code that is a joy to skin and modify. Unlike some of it’s peers, there are no tables to be seen.  It is a fork of PunBB, again an older piece of software some of you may already be familiar with that has brought with it even cleaner more compact code.  Considering that Pun moved to a commercial company a while back, its a welcome one as well.

One feature that some of you may find particularly useful is FluxBB ability to run on SQL lite, meaning it could in theory become part of a native mobile application – as the database could be shipped along with the application. Conformance with Accessibility guidelines is also a plus and the clean code and architecture will please the standards zealots amongst you.. If you are looking for a fully fledged feature set, again it’s probably not going to be up your street, but if you are looking to get moving quickly, with the core forum features you’d expect, FluxBB won’t disappoint.

  1. Hi Paul, great blog post as always!

    A client of ours asked us to implement a Simpley Machines forum. There wasn’t much skinning needed for the project, but it was a simple package to install and get up and running. The client seems happy with the functionality. Seems pretty stable too.

    Cheers,
    Phil

  2. You can add NinkoBB to it. Raw, but great.
