Agents

Autonomous and orchestrated multi-step AI workers.

259 tools

Why it matters

The agent ecosystem is the youngest category here — frameworks, orchestrators, and end-to-end autonomous workers are evolving fast, with reliability and observability still maturing.

What's in here

Includes orchestration frameworks (LangGraph, CrewAI, Claude Agent SDK), end-to-end product agents (Devin, Manus), and open-source platforms (AutoGPT, OpenAI Swarm).

How to pick

Pick LangGraph when production reliability matters. Pick CrewAI for fast multi-agent prototyping. Pick Claude Agent SDK if you're Claude-aligned. Use Devin / Manus when you want a finished agent product, not a framework.
