swe-bench

SWE-bench: benchmark for evaluating LLMs on real-world GitHub issue resolution across 12 popular Python repositories.

microsandbox

Use as the OSS self-hosted sandbox when you need to run agent code on your own infra: libkrun-based microVM isolation with no per-sandbox vendor cost, the escape hatch from a managed runtime at high volume.

helicone

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

giskard

Open-source LLM testing framework for detecting vulnerabilities (prompt injection, hallucinations, bias) via automated scan.

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).

agenta

Open-source LLM developer platform with prompt playground, evaluation pipelines, and A/B testing for iterating on LLM apps.

openai-simple-evals

OpenAI's lightweight benchmark suite (MMLU, HumanEval, MATH, GPQA, MGSM) for fast model capability comparisons.

caviraoss-openmemory

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

claude-managed-agents-selfhost

Use for enterprise hosted-control agents (the agent loop runs at the provider while execution happens on your own infrastructure) when you want a managed control plane but data and code must stay on your machines.

big-bench

Google's Beyond the Imitation Game benchmark: 200+ diverse tasks designed to probe capabilities beyond standard NLP benchmarks.

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.

trulens

Evaluation and tracking for LLM and RAG applications with a feedback-function API and experiment dashboard.

xlang-ai-osworld

[NeurIPS 2024] OSWorld: Benchmarking Multimodal Agents for Open-Ended Tasks in Real Computer Environments

Contributed by Sentinel

inspect-ai

UK AISI's framework for safety evaluations of large language models, with task-based scaffolding and solver pipelines.

mirix-ai-mirix

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

helm

Stanford CRFM Holistic Evaluation of Language Models: standardized benchmark suite covering accuracy, calibration, robustness, and fairness.

sysbox

Next-generation container runtime enabling Docker-in-Docker and VM-like isolation without privileged containers.

lighteval

Hugging Face lightweight evaluation library for LLMs across academic benchmarks, with fast local and remote inference support.

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.
