Similarities
- Both are designed for the enterprise
- Both are reusing exisiting components with a goal to produce a unified user experience
- Both are upstreaming all fixes and enhancements
- The teams behind each project have a long experience of producing FLOSS apps (OBM and Tiki Wiki CMS Groupware)
Differences
- OpenSaaS is the next generation of OBM. It's a rewrite in a different programming language while taking advantage of their extensive experience in the field. This has the "green field advantage"
- WikiSuite was born out Tiki Wiki CMS Groupware to address the need to expand out and add new functionality by partnering up with complementary components. This has the advantage of a more mature code base and the disadvantage of some feature overlap. Some glueware between the components is required. In some cases, it's seamless and clean because (ex.: it's using an open standard so it's a desired extension point anyway). In some other case, it's not so clean because it's to compensate for overlap between applications.
- OpenPaaS does not support XMPP (but there are plans for a gateway) while WikiSuite picked Openfire to fully support XMPP and to participate to improving XMPP over the long term.
