Heimdall: A CPU-Only Agent Memory System with Zero LLM Overhead
Slight-Parfait3679 · reddit · 2026-08-25
The author released Heimdall, an open-source CPU-only memory system for agents designed to fix graph-based knowledge maintenance issues. It installs via npm and addresses persistent memory and repository knowledge gaps.
By injecting relevant prior context into the first prompt, Heimdall replaces inefficient bash commands like ls and grep, reducing token usage and speeding up the first useful action. The system uses zero LLMs for storage, includes enforcement layers, and has shown strong scores on LongMemEval (S=95%). The author is seeking community input for edge cases and self-healing optimization.
