steel-browser

Open-source browser API optimised for AI agents. It provides session management, stealth settings, proxy rotation, and a REST/WebSocket interface on top of Chromium for cloud-scale agent browser access.

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.

giskard

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

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.

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.

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.

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.

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.

open-operator

Browserbase Open Operator: an open-source Operator-style web agent built on Stagehand; demonstrates full task decomposition, action planning, and evidence collection using the Browserbase cloud.

notte

Notte open-source web agent environment. It converts browser sessions into a Markov Decision Process with structured observation/action spaces, making browsers first-class RL and LLM agent environments.

evalplus

Rigorous code generation evaluation framework built on top of HumanEval and MBPP with 80x more test cases.

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

webarena

WebArena: realistic web-based environment for evaluating autonomous agents on long-horizon browser interaction tasks.

tau-bench

Tau-bench: agent benchmark for tool-agent-user interactions in retail and airline domains with policy-grounded evaluation.

harbor-framework-terminal-bench

Measuring and evolving with the frontier of agent work

e2b-desktop

E2B Desktop Sandbox: a cloud virtual desktop (Ubuntu + VNC) with Python SDK for screenshot, mouse, keyboard, and process control; designed for AI agents that need a full GUI environment in an isolated VM.

agent-e

Emergence AI agent-E browser agent: hierarchical LLM-based web automation that uses DOM distillation and action abstraction layers to achieve significantly higher benchmark accuracy than prior browser agents.
