At least five open-source ERP projects exist today, but just three of those\u2014Compiere, Open For Business and Openbravo\u2014have gained traction, analysts say. In order of age:Compiere: Founded in 1999, this project has the most adoption and \u201chas grown into a significant level of functionality,\u201d says Paul Hamerman, a Forrester Research analyst. Compiere particularly suits sales, CRM and retail uses, but for manufacturing, lacks shop floor management capabilities, says Martin Schneider, an analyst at The 451 Group.Open For Business: Part of the Apache group of projects, the first version was released in 2005. It\u2019s best suited for online businesses, says Peter Bohnert, a principal at Transactional Data Systems.Openbravo: First released in 2006, Openbravo is designed for customization, rather than for a specific type of industry. It\u2019s Web-based, so companies with remote offices and traveling executives can provide browser-based access to simplify deployment and client management\u2014attributes that won over pharmaceuticals supplier Galenicum\u2019s COO, Erich B\u00bfchen. Less-established open-source ERP projects include WebERP and ERP5. Note that a few ERP applications are often considered to be open source but are not: OpenMFG, a well-regarded commercial application for manufacturers, lets licensed users access and modify the code for their own use, but not redistribute the code. Tiny ERP, a free ERP application, is nonetheless licensed and its code is not available.
