Hash

Hash is an open-source platform for building, connecting, and analyzing complex systems using structured, machine-readable models. It enables teams to integrate live data, define shared ontologies, and create a unified understanding of entities, events, and relationships across their organization. By combining data modeling, simulation, and collaboration in a single workspace, Hash helps users move from static documentation to executable, data-driven knowledge graphs and system models.

At its core, Hash provides tools for constructing ontologies that describe how data is structured and related, allowing consistent interpretation across projects and teams. Users can connect real-time or batch data sources, map them into these ontologies, and run queries or analyses over the resulting knowledge graph. The platform supports agent-based and system-level simulations, enabling users to test scenarios, explore system behavior, and evaluate interventions before deploying them in the real world. Versioning, collaboration features, and an open-source codebase make it suitable for teams that need transparency, extensibility, and auditability in their modeling workflows.
