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.

agiresearch-a-mem

A-MEM: Agentic Memory for LLM Agents

Contributed by Sentinel

webvoyager

Research browser agent from Zhejiang University and HKU. It uses GPT-4V interleaved screenshot + HTML observations to complete open-ended web tasks; established an early web-agent benchmark (WebVoyager).

surf-computer-use

E2B Surf: a Stagehand-powered computer-use interface layer for E2B Firecracker sandboxes; connects the act/extract/observe primitives directly to microVM display output for lightweight headless computer use.

claude-powerline

A vim-style powerline statusline for Claude Code with real-time usage tracking, git integration, custom themes, and more

codeabra-iai-personal-memory-engine

Use when the agent should remember not just facts but how you like to work, locally and for free.

modal-labs-modal-client

Modal — serverless GPU/CPU containers for running agents, sandboxes and model inference from Python (this is the client SDK).

claude-code-statusline

Enhanced 4-line statusline for Claude Code with themes, cost tracking, and MCP server monitoring

phospho

Phospho is a text analytics and evaluation platform for LLM apps. It logs sessions, runs clustering, detects failures, and surfaces actionable insights.

athina-ai

Athina AI provides developer-focused LLM monitoring and eval framework: real-time inference logging, automated evals, and regression detection in CI.

claude-pace

A lightweight Bash + jq statusline for Claude Code that displays rate limit pace delta (burn rate vs. time remaining), 5h/7d usage percentage, context window usage, git branch and diff stats. Compares current consumption rate against time remaining in each rate limit window to indicate whether quota is being used faster or slower than the window allows. Single file with no external dependencies beyond jq.

nemori-ai-nemori

Use when you want to see whether aligning memory to episode-sized chunks beats a heavier memory framework.

jean-technologies-jean-memory

Use when you want mem0-style and graph-style memory combined behind one interface.

kyros-ai

Use when the agent's memory needs to resolve its own contradictions and forget on a schedule.

claudia-statusline

High-performance Rust-based statusline for Claude Code with persistent stats tracking, progress bars, and optional cloud sync. Features SQLite-first persistence, git integration, context progress bars, burn rate calculation, XDG-compliant with theme support (dark/light, NO_COLOR).

e2b

Open-source secure cloud sandboxes (Firecracker microVMs) for running AI-generated code. ~150ms cold start.

modal

Serverless cloud platform for running Python functions, containers, and AI workloads with zero infra management.

railway

Zero-config cloud platform for deploying agent backends, databases, and services from a Git push.

vercel

Frontend cloud platform with serverless functions and AI SDK integrations for deploying agent-facing UIs.

honeycomb

Honeycomb's OpenTelemetry-native observability platform: a high-cardinality event store ideal for tracing LLM pipelines and debugging slow agent traces.

baserun

Baserun captures LLM traces via a lightweight decorator-based SDK and provides a dashboard for debugging prompt chains, testing variants, and measuring quality.

wikimem

Use to give an agent a queryable wiki knowledge base when memory should be a navigable knowledge graph, not just a flat log: ingest files, folders, and URLs into a linked vault, then search or ask it in natural language.

3d-artist

3D art and asset creation specialist for game development. Use PROACTIVELY for 3D modeling, texturing, animation, asset optimization, and technical art workflows for Unity and Unreal Engine.
