Independent use will determine whether Engrava’s SQLite-based graph database provides a practical and reliable local persistence layer for AI-agent memory.

What is this?

Engrava is presented by Sovantica as an MIT-licensed, local graph-memory database for AI agents built on SQLite; its repository describes the root commit as the “Initial public release.” The supplied background supports SQLite as a zero-operations, inspectable local persistence option and graph representations as a way to preserve relationships across memories, while also noting graph extraction costs and reliability limits. No independent evaluation of Engrava itself is supplied, so its practical performance, durability, and retrieval quality remain unestablished.

Why it matters to Scott

This is another unvalidated implementation of Scott’s durable external-state and graph-memory architecture, already represented in `durable-external-state`, `The Index Is the Data`, and the active `dev-wiki` project. The radar also already tracks the same local SQLite-memory and agent-maintained wiki-graph territory through `MCP Memory` and `Karpathy-style LLM Wikis`; without independent results, Engrava adds a candidate implementation rather than evidence that would change what Scott builds or argues.
