Cayley has no write-up on Specifiction yet; its figures are above.

TypeDB is a structured hypergraph database with an enforced, schema-first model: reads and writes are validated against the schema. Its TypeQL query language is declarative, functional, and strongly typed. Relations can link any number of entities or attributes, and can link to other relations. TypeDB is presented for agentic systems, cyber threat intelligence, knowledge graphs, financial intelligence, and robotics; it also lists vector search and ACID transactions. Platforms include API, Linux, macOS, self-hosted, web, and Windows. Official drivers are listed for Python, TypeScript HTTP, Rust, Java, C, and C#, with C++ marked as planned. The free Explore plan costs nothing and includes a fully managed dedicated database server with 10 GB storage, 8 GB RAM, and 2 vCPUs. Launch costs $0.07 a month, billed from $0.07 per hour. Enterprise has custom pricing and supports on-premises or customer-cloud deployment, including air-gapped environments.
