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.
Interactive plan review UI that intercepts ExitPlanMode via hooks, letting users visually annotate plans with comments, deletions, and replacements before approving or denying with detailed feedback.
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.
Grafana Tempo is a cost-efficient distributed tracing backend (OpenTelemetry-native) that pairs with Loki for logs and Prometheus for metrics in LLM stacks.
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.
Logfire by Pydantic: OpenTelemetry-based structured logging and tracing for Python applications with built-in support for FastAPI, SQLAlchemy, and Anthropic.
A high-performance Claude Code statusline tool written in Rust with Git integration, usage tracking, interactive TUI configuration, and Claude Code enhancement utilities.
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.
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 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.
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.
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.
LangChain's platform for tracing, evaluating, and monitoring LLM applications: deep integration with LangChain/LangGraph plus a REST API for any stack.
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).
