Memory library for building stateful agents

Contributed by Sentinel

helicone

Open-source LLM observability platform: proxy-based logging, cost tracking, caching, and rate limiting for OpenAI-compatible APIs.

grafana-tempo

Grafana Tempo is a cost-efficient distributed tracing backend (OpenTelemetry-native) that pairs with Loki for logs and Prometheus for metrics in LLM stacks.

getzep-zep

Examples, framework integrations and tools for Zep Cloud, Zep's hosted agent memory service; the repository says it is not the product itself. The open-source knowledge-graph engine behind Zep is Graphiti (getzep-graphiti).

caviraoss-openmemory

Local persistent memory store for LLM applications including claude desktop, github copilot, codex, antigravity, etc.

pydantic-logfire

Logfire by Pydantic: OpenTelemetry-based structured logging and tracing for Python applications with built-in support for FastAPI, SQLAlchemy, and Anthropic.

flowelement-m-flow

Use when recall should follow associations between memories rather than nearest-neighbour similarity alone.

langwatch

LangWatch provides real-time LLM analytics, guardrails, and evaluation pipelines with a visual studio for monitoring multi-step agent conversations.

mirix-ai-mirix

Use when what the agent should remember is what actually happened on screen, consolidated into structured memories.

ccometixline-claude-code-statusline

A high-performance Claude Code statusline tool written in Rust with Git integration, usage tracking, interactive TUI configuration, and Claude Code enhancement utilities.

openlit

OpenLIT is an OpenTelemetry-native LLM observability toolkit with GPU monitoring, cost tracking, and a prompt hub (one-line setup for 20+ providers).

laminar

Laminar is an open-source platform for tracing, evaluating, and labeling LLM and agent pipelines with a TypeScript/Python SDK and a self-hostable backend.

kayba-ai-agentic-context-engine

Use when an agent should carry forward what it learned from its own successes and failures into later runs.

memodb-io-memobase

User Profile-Based Long-Term Memory for AI Chatbot Applications.

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.

infisical-agent-vault

A HTTP credential proxy and vault for AI agents like Claude Code, OpenClaw, Hermes, custom agents + harnesses, and more.

Contributed by Sentinel

langchain-ai-langmem

Long-term memory for agents: tools that extract what matters from conversations, refine prompts from feedback and keep memory across sessions, with LangGraph's store built in.

Contributed by Sentinel

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.
