Overview
openCRX is an open source CRM and groupware server published by CRIXP, a company based in Switzerland. It covers sales force automation, customer service and support, marketing automation, and analytics across customers, partners and suppliers. The core records are accounts, contacts, activities and issues, products, contracts and campaigns. The groupware side handles e-mail, contacts and calendars, and the server can act as an ActiveSync server so iPhone and Android devices can sync with it. It runs on any Jakarta EE 8 Web Profile server. The standard installer bundles Apache TomEE, Docker is supported, and it works with all major databases. Developers get a Java API, a Swagger-compliant REST API, and customization that ranges from XML-based screen changes to extending business logic. The software is free under a BSD license with no subscription tiers, so the costs a team pays are hosting and staff time. The official site lists version 5.3.2, dated January 2025, as the latest release. It suits IT departments and companies that want full control over their CRM data. The main limitation is the effort involved. Reviewers point to thin documentation, support that is hard to find, a dated and sometimes slow interface, and the need for technical expertise to configure it.
Our Rating
Who openCRX is best for
Good fit
- IT Teams7/10
The notes say it suits IT departments that want full control, since it is self-hosted on Jakarta EE with Docker support.
Less suited
It offers a Java API, a Swagger REST API and extensible business logic, though the documentation is thin.
The vendor describes it as an enterprise-class, scalable server, but enterprises have to support it themselves.
- Mid-Market5/10
It fits mid-sized firms that have in-house IT staff to host and extend it.
It covers sales force automation, leads and opportunities, but reviewers report a slow interface and no native mobile apps.
It includes customer service and issue tracking, but it is not a dedicated help desk.
Small businesses get it for free, but reviewers say it takes technical expertise to configure.
It is free under a BSD license, but running it takes technical setup effort and the support is weak.
