BlitzGraph

BlitzGraph is a hosted graph backend designed to be driven by AI agents. Instead of tables, SQL and an ORM, developers and agents model data as entities connected by relationships and query it with BQL, a typed JSON query language, so an agent composes structured query objects rather than generating SQL strings. The pitch is that an idea goes in and a working API comes out. It is aimed at developers building applications with coding agents such as Claude Code and Codex, which connect to it as a remote MCP server with browser sign in. The data model allows one entity to hold several kinds at once, for example a user who is also an admin, and relationships are traversable in both directions at the same cost. A single BQL request can combine filters, nested expansions, projections, aggregations and full text search, with a built in BM25 search engine instead of a separate service. Schemas carry typed fields such as email, URL and date, cardinality constraints and delete policies, and business logic including validations, computed fields, hooks and transforms. Mutations run as all or nothing transactions validated against their final state, and the platform adds live queries, actions and workflows, agent sandboxes and a BlitzStudio interface. A public playground runs against live data without an account. Pricing is not published. The site invites developers to build their own backend for free during the public beta and offers demos on request, but no paid plans or limits are listed on a pricing page. BlitzGraph is in public beta and warns that occasional interruptions may occur. It is backed by Y Combinator.
