Build stateful, multi-actor applications with LLMs
Agent FrameworksMulti-Agent Platforms
LangGraph by LangChain enables building stateful, multi-step agent workflows as graphs. It provides fine-grained control over agent behavior with built-in persistence, human-in-the-loop, and streaming support.
AI pair programmer that helps you write code faster
Coding Agents
GitHub Copilot uses AI to suggest code completions, generate entire functions, and now features an agent mode that can autonomously implement features, fix bugs, and run tests across your codebase.
Anthropic's agentic coding tool that lives in your terminal
Coding Agents
Claude Code is an agentic coding assistant by Anthropic that operates directly in your terminal. It can understand your codebase, edit files, run commands, and handle complex multi-step engineering tasks autonomously.
Windsurf (formerly Codeium) is an AI-powered IDE that combines copilot and agent capabilities. It offers deep codebase understanding, multi-file editing, and autonomous command execution.
Build and deploy AI agents for your workforce without code
Sales & MarketingWorkflow Automation
Relevance AI lets you build custom AI agents that can handle sales, support, research, and operations tasks. No coding required — create agents with natural language instructions and connect them to your tools.
Registry and marketplace for Model Context Protocol (MCP) servers
Agent Frameworks
Smithery is the central hub for discovering and sharing MCP servers. It enables AI agents to connect to external tools, APIs, and data sources through the standardized Model Context Protocol.
AI-powered full-stack web development agent in the browser
Coding Agents
