Browser Use
Open-source web browsing AI agent for Python & LangChain
About Browser Use
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.
Install the Python package via 'pip install browser-use' and configure Playwright.
Initialize an LLM controller (Claude 3.7 Sonnet, GPT-4o, or local Ollama model).
Provide an autonomous task objective in natural language (e.g. 'Search for flights and download receipts').
The agent inspects the DOM tree, executes targeted clicks and keyboard actions, and validates page state transitions.
Receive structured output data or downloaded artifacts with complete execution traces.

View allStagehand
AI-powered browser automation SDK built on Playwright
Stagehand is an AI-native browser automation SDK for TypeScript and Node.js created by Browserbase. It provides simple, high-level primitives (act, extract, and observe) that turn fragile CSS/XPath selectors into resilient natural language actions powered by frontier LLMs. By integrating directly with Playwright, Stagehand allows developers to mix standard deterministic browser code with dynamic AI-driven actions, creating test suites and automation scripts that never break when CSS classes or DOM hierarchies change.
Anthropic Console
Enterprise-grade AI for developers
The developer gateway to Claude models, offering advanced controls like prompt caching and Artifacts rendering via API.
Hostinger Agent
Autonomous AI agent for website generation, server infrastructure, and business automation in hPanel
Hostinger Agent is an autonomous, full-stack AI agent integrated natively into Hostinger's hPanel environment. It combines intelligent website generation, server infrastructure management, and business operations into a unified conversational interface. Whether you need to build custom web applications from scratch, configure complex DNS records, manage VPS instances, or automate business workflows, Hostinger Agent executes tasks directly on your hosting environment with production-grade reliability. Unlike traditional static AI website builders that only generate layout templates, Hostinger Agent operates with deep infrastructure awareness. In Agent Mode, it can autonomously create directories, write backend Node.js code, provision databases, and deploy React/Vite frontends. In Support Mode, it provides real-time technical troubleshooting and step-by-step assistance, offering a comprehensive operations copilot for solo developers, founders, and growing agencies.
Smolagents
Lightweight, code-first multi-agent framework by Hugging Face
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%.
LiveKit Agents
Open-source real-time WebRTC infrastructure for building ultra-low-latency voice and multimodal AI agents
LiveKit Agents is an open-source real-time communication framework engineered to build conversational voice, video, and multimodal AI agents with sub-500ms latency. Leveraging WebRTC, it connects speech-to-text (Deepgram, Whisper), LLMs (OpenAI, Anthropic), and text-to-speech (Cartesia, ElevenLabs) in a tightly synchronized bidirectional stream. From customer service avatars to interactive language tutors and hands-free coding copilots, LiveKit Agents provides the enterprise infrastructure for real-time human-AI interaction.
Agno
High-performance multimodal AI agent framework with native memory and speed
Agno (formerly Phidata) is a lightweight, ultra-fast Python framework engineered for building production-grade autonomous multi-agent systems with native memory, knowledge retrieval, and multimodal reasoning capabilities. It is designed to replace bloated agent frameworks with a pure, pythonic developer experience. Agno agents operate up to 10x faster than legacy orchestration libraries by eliminating unnecessary abstractions. With built-in support for vector databases (PgVector, Qdrant, Pinecone), structured output schemas, and agent-to-agent delegating protocols, developers can build complex autonomous assistants with under 20 lines of clean code.
