CrewAI

CrewAI lets you define a crew of agents, each with a role, a goal and a set of tools, then give the crew a task to complete together. For example, one agent researches, another writes and a third reviews. It is known for being approachable, with a clear way to describe agents and tasks, and it also supports more controlled flows for steps that must happen in order. The open-source framework is Python-based. The core library is free, and CrewAI also sells an enterprise platform for deploying and monitoring crews. It is a good fit for people who think of automation as a small team of specialists.
