HybridForms Core Server for SQL – powerful, flexible & data‑sovereign

The central server backend of HybridForms runs on Microsoft SQL Server or PostgreSQL—on‑premises, in the Azure cloud, or within your private cloud infrastructure. Scalable from just a few users to enterprise deployments with more than 10,000 users.

SQL as a stable foundation for projects of any size

The HybridForms Core Server uses Microsoft SQL Server or PostgreSQL as the central database backend – completely independent of SharePoint or other third‑party platforms. Its own business logic, a dedicated admin layer, and clearly defined API interfaces provide maximum control over functionality, security, and release cycles.

Whether a lightweight installation for a single team or a company‑wide rollout with multi‑tenant management and thousands of users: the architecture scales linearly and without hidden licensing pitfalls.

In addition to Microsoft SQL Server, HybridForms also supports PostgreSQL. This gives organizations a cost‑efficient, vendor‑independent database platform that requires no compromises in functionality or stability.
