WikiSuite | WikiSuite vs Odoo

Odoo and WikiSuite have some similarities. This page is to explain the differences and rationale of choices. You likely will be interested in the other alternatives to WikiSuite.

Odoo started out as an ERP but has since branched out to other enterprise use cases (and thus the last name change). Odoo was previously known as OpenERP, and before that TinyERP

Similarities

Both are solutions with a large number of features for the enterprise

Differences

Odoo is an Open Core licensing model so some of the apps are proprietary which makes some things more complicated, while WikiSuite is 100% Free / Libre / Open Source.
Odoo is way stronger on the financial features (Accounting, Timesheets, etc)
- But many of those stronger features are not Free/Libre/Open Source: https://www.odoo.com/page/editions
Odoo is promoting its cloud offering while WikiSuite is encouraging you to host on any virtual machine provider, or on hardware in your infrastructure.
Odoo offers a lot of features but it doesn't have the feature scope of WikiSuite. It's more comparable to Tiki Wiki CMS Groupware.
Odoo reports having over 10 000 apps which leads to: plugin problems, like fragmentation and difficult upgrades.
Odoo indicates that "We reviewed the current Odoo 8.0 source code and the amount of code that was not developed by Odoo staff represents about 2% of the code base." while WikiSuite has a much more diverse contribution base.
Odoo is often better at having a 1-click app which addresses a use case, where as in WikiSuite, this is covered by Tiki trackers which often require configuration. Tiki profiles do this but there are not enough and they are not well promoted.

About upgrades, data confidentiality and a fundamental difference of philosophy

Odoo recommends a support plan, and have them handle version upgrades of your database (ex.: Odoo 9 to 10) so there is a a community effort alternative.
- "This is a community initiative under the Odoo Community Association umbrella, as the open source version of Odoo Community Edition (CE) does not support migrations from one major release to another."
The mission of WikiSuite is to "Empower organizations to better manage, secure and use their information, to become data-driven, and achieve their optimal performance.", and thus, it is unthinkable for organizations to have to send their data to one software vendor (and Odoo typically manages financial data!). In WikiSuite, all code related to upgrades is made available with the same free / libre / Open Source license as the rest of the software. We want to make it as easy as possible to upgrade so the community has access to the latest and greatest software.
