The score comes from our model.

• Show HN: Minigraf – An embedded, bi-temporal graph database in Rust · score 8.0

  Minigraf is an embedded, single-file graph database written in Rust, featuring Datalog queries, bi-temporal time travel, and zero configuration. It combines the simplicity of SQLite with the temporal model of Datomic, targeting AI agents, mobile, and browser environments with native and WASM support.

• Show HN: Glider: A single-node vector database with S3 as its only durable state · score 7.8

  Glider is a single-node vector database that uses S3-compatible object storage as its only durable state, ensuring every write is persisted before acknowledgment. It offers nearest-neighbor search with metadata filters via HTTP/JSON, includes Python and MCP clients for AI agent memory, and provides robust features like crash-safe takeover and retry-safe writes. Its innovative architecture and thorough documentation make it a compelling solution for durable, cloud-native vector search.

• Show HN: KiviDB, a faster Redis-compatible memory database and vector cache · score 7.3

  KiviDB is a Redis-compatible in-memory database written in Rust that leverages multi-threading and sharding for high throughput, claiming 9x Redis performance on pipelined GETs. It includes built-in full-text and vector search (FT.* commands) and supports snapshots and AOF persistence, making it a drop-in alternative for Redis Stack use cases.

• Show HN: Dbprint – Database Context for Agents · score 7.0

  dbprint profiles live database schemas and data to generate committed plain-text artifacts (DDL, statistics, join graphs, annotations) that coding agents can read offline via an MCP server or CLI, avoiding repeated warehouse queries. It combines multi-engine profiling, agent-assisted annotation of ambiguous values, and CI-checkable data drift detection into a Git-native context layer for AI coding agents.
