Developer builds Valori, an open-source memory engine for AI agents in Rust

A developer spent a year building Valori, an open-source memory engine for AI agents written in Rust. It evolved from a vector database into a broader system featuring deterministic Q16.16 vector engine, GraphRAG, knowledge graph support, event-sourced storage with BLAKE3 audit chain, and multiple index types. The project is seeking feedback from the community.

Valori is an open-source memory engine for AI agents, built in Rust over the past year. It started as a vector database but expanded to include: deterministic Q16.16 vector engine (no floating-point state), GraphRAG and knowledge graph support, event-sourced storage with a BLAKE3 audit chain, verifiable memory and execution history, HNSW, IVF, Binary Quantization, and brute-force indexes, standalone and distributed architecture with Raft, a Python SDK, and a graph execution pipeline (currently inline). The developer is seeking brutally honest feedback from the community.

Enola: engineering intelligence layer for AI coding agents

Enola is an open-source engineering intelligence layer that helps AI coding agents understand existing codebases. It answers questions about change impact, dependency reachability, safe module deletion, refactoring priorities, and architecture drift. The tool uses LLMs to analyze code context and provide insights that reduce mistakes from both humans and AI agents.
