In their own words
HASH
HASH is an open-source platform that models an organization with a knowledge graph and a process graph. The continuously updated model supports analytics, workflow automation, what-if simulations, AI agents, and detailed access governance. HASH can ingest connected applications and structured data, infer entities from unstructured material, and passively collect selected web information. Its bitemporal graph records transaction time and decision time, letting users inspect earlier states and provenance without overwriting records. Flows combine triggers, actions, filters, and waits and can run manually, automatically, or programmatically. Agents can answer questions and take actions. Integrations include Slack, Google Drive, Gmail, Notion, GitHub, SAP S/4HANA, Snowflake, and Postgres. Two-way synchronization is available where supported; some services allow only read-only sync or one-time imports. A browser extension can collect selected browsing information, let agents access sites for users, and launch flows. HASH is offered through web, API, browser extension, or self-hosted deployment. The free plan includes 10GB storage and 50 entities per manual scraping job. Plus starts at $20 a month when billed annually.
Oxigraph
Oxigraph is a free graph database and RDF/SPARQL toolkit available for Linux, web, API, and self-hosted use. It implements SPARQL 1.1 Query, Update, and Federated Query, and handles RDF formats including Turtle, TriG, N-Triples, N-Quads, RDF/XML, JSON-LD, and N3. The project provides a Rust library, standalone Rust crates, Python bindings, JavaScript bindings, and a command-line tool. That CLI can start an HTTP server implementing the SPARQL 1.1 Protocol and Graph Store Protocol. By default, the server listens on localhost:7878 and offers a YASGUI-based HTML interface for running SPARQL requests. REST endpoints support queries, updates, and RDF dataset access. Installation options include Cargo, Docker, PyPI, conda-forge, and prebuilt binaries. Pyoxigraph supplies in-memory and disk-based stores, and oxrdflib connects rdflib stores to Pyoxigraph. Storage is based on RocksDB, and licensing is Apache 2.0 or MIT.
