Limbas is a German open-source, low-code database framework for CRM, DMS and ERP apps. See features, GPL licensing, pricing and top alternatives for 2026.
Limbas is an open-source, low-code database application framework maintained by LIMBAS GmbH, a German software company based in Oberhaching, Bavaria, that has worked in the open-source space since 1996. Rather than shipping as a single finished product, Limbas provides a graphical database front-end and application-building layer that development teams use to construct custom CRM, DMS, ERP, groupware and CMS systems on top of existing enterprise databases.
The framework connects to a wide range of relational databases including PostgreSQL, MySQL, Microsoft SQL Server, Oracle and SAP MaxDB or HANA, and is released under the GNU GPL v2.0, meaning the full source is available and self-hostable at no license cost.
Limbas offers a form and workflow builder for creating data-entry interfaces without extensive custom coding, ODBC and native connectors for integrating with SAP and other enterprise IT systems, and configurable modules that have been used to implement CRM, document management and test-equipment tracking systems.
Because it is framework-based rather than a fixed vertical application, Limbas is most valuable to organizations with in-house PHP or low-code development capacity, or those working with LIMBAS GmbH consultants, who can assemble a system tailored to specific internal processes rather than adapting to a rigid, pre-built product.
The core OpenLIMBAS framework is free to download and self-host under its GPL license. LIMBAS GmbH generates revenue through professional services, custom implementation, and a commercially hosted offering called LIMBAS live, which bundles managed hosting and support for organizations that prefer not to run the software themselves.
Because pricing for hosting and services is quoted per engagement, prospective users typically need to contact LIMBAS GmbH directly for a custom quote rather than selecting from published subscription tiers.
The core OpenLIMBAS framework is free and open source under the GNU GPL v2.0 license for self-hosted deployments. The commercially hosted LIMBAS live offering and professional services are priced separately.
Limbas is a low-code database framework used to build custom CRM, document management (DMS), ERP, groupware and CMS applications on top of existing enterprise databases.
Limbas connects to PostgreSQL, MySQL, Microsoft SQL Server, Oracle and SAP MaxDB or HANA via PDO and unixODBC.
Limbas is developed and maintained by LIMBAS GmbH, a German software company headquartered in Oberhaching, Bavaria, that has worked in the open-source software space since 1996.
Limbas is a low-code platform, so many tasks can be done through its form and workflow builder, but self-hosting and deeper customization generally require PHP and Linux server administration skills.
Limbas offers deeper native connectivity to enterprise databases like SAP MaxDB and Oracle, while Baserow and NocoDB provide more modern, spreadsheet-style interfaces and larger open-source communities.
