Browser Use

Browser UseSince 2026-01

Browser Use is an open-source Python library that connects LLMs to browser automation pipelines, enabling AI agents to navigate websites, interact with dynamic DOM elements, bypass multi-step forms, and extract structured data autonomously. Built on top of Playwright and LangChain, it provides vision-augmented element detection and deterministic state tracking. Unlike traditional headless scrapers, Browser Use feeds DOM tree snapshots and viewport screenshots to multimodal models like Claude 3.7 Sonnet or GPT-4o, allowing agents to understand complex UI layouts, handle popups, solve interactive workflows, and execute sequential tasks in plain English.

Browser Use utilizes an innovative DOM accessibility tree pruning algorithm to minimize token consumption while maintaining complete interactive context. The library exposes clean async Python primitives, custom action handlers, and persistent session cookies, making it ideal for automating authentication-heavy corporate portals, booking workflows, and complex SaaS configurations. The agent logs every click, keystroke, and reasoning trace, allowing developers to inspect execution replays and enforce security sandboxing before dispatching production workflows.

SmolagentsSince 2026-01

Smolagents is an ultra-lightweight, code-first Python framework created by Hugging Face for building, orchestrating, and executing autonomous AI agents in minimal lines of code. Rejecting the bloated, multi-layered abstractions of legacy agent libraries, Smolagents emphasizes 'Code Agents'—agents that express their reasoning and tool actions directly in executable Python code rather than rigid JSON string payloads. By letting LLMs write executable Python logic, Smolagents achieves vastly superior composability for data manipulation, mathematical operations, and complex loops while cutting prompt token overhead by up to 30%.

Smolagents natively supports both local open-source models (via Hugging Face Transformers and Ollama) and commercial frontier models (via LiteLLM, OpenAI, and Anthropic APIs). It includes pre-built modules for secure sandboxed Python execution, multi-modal web browsing agents with visual comprehension, and seamless sharing of agent tools directly on the Hugging Face Hub. The framework is fully modality-agnostic, supporting text, speech, vision, and custom API tools with zero vendor lock-in.
