Relatude.DB — the all-in-one datastore for web applications

An open-source, object-oriented graph datastore for .NET where your C# classes are the schema — no SQL, no migrations, no ORM layer. Search, facets, files and an admin UI are built in, and it runs in-process or as a standalone server. Media management, video conversion and vector indexing come out of the box. It is fast, light on resources, and built to carry demanding web applications.

That makes it a perfect match for AI agents. Building the same thing from separate systems is a mess — these are safe, powerful blocks your AI can use directly, with code that stays small and under your control.
