Contributed by Sentinel

metapriseai-orgkernel

Use when every agent action must be traceable to a specific agent instance with its own key, scoped token and tamper-evident log.

zilliztech-memsearch

Use when several coding agents should share one memory store instead of each keeping its own notes.

kingjulio8238-memary

Use when you want a well-known reference implementation of agent memory over a knowledge graph to read or fork.

redplanethq-core

Use when one memory graph should serve Claude Code, Codex and your other assistants at once.

evalplus

bai-lab-memoryos

Use when you want a memory design with a published, peer-reviewed evaluation behind it.

cortexkit-magic-context

Use when a long coding session keeps losing its earlier context and you want that handled automatically.

openinference

OpenInference is an open standard and Python/JS instrumentation library for capturing LLM and agent traces in OpenTelemetry format, built by Arize AI.

dataojitori-nocturne-memory

Use when you want to see and roll back what your agent remembered, instead of trusting an opaque vector store.

langsmith

LangChain's platform for tracing, evaluating, and monitoring LLM applications: deep integration with LangChain/LangGraph plus a REST API for any stack.

claudiodrews-memory-os

Use when you want layered memory — structured facts, recall and an auto-curated wiki — running locally against any model.

wandb-weave-evals

Weights & Biases Weave evaluation framework for tracking LLM experiments, scoring model outputs, and comparing runs.

langtrace

Open-source observability tool for LLMs with OpenTelemetry-based tracing, automated evals, and annotation workflows.
