16 Data Paradigms. One Connection. One Theoretical Framework. SQL, Document, Vector, Graph, and more--unified under one connection. Native PostgreSQL ACID for SQL operations; cross-model atomic workflows coming soon.
Fundamental paradigms, unified under one framework.
PolyDB doesn't just combine databases; it unifies the underlying data theory. Each model is optimized for its domain while sharing the same backend, security layers, and connection management.
Intelligent defaults out of the box. Start coding instantly with any model.
from polydb import PolyDB, PolyDBConfig # Unified Model Entry Point db = PolyDB(PolyDBConfig()) # One connection to rule them all db.sql.execute(...) db.doc.insert(...) db.vec.search(...) db.graph.add_edge(...)
