Promptfoo vs CrewAI
Side-by-side comparison to help you choose the best tool.
Promptfoo
freemiumPromptfoo is an open-source LLM testing and evaluation system. It allows developers to run prompt evaluations, compare model outputs, detect regressions, and red-team LLM applications to catch failures before they reach production.
Best for: Teams that need systematic prompt testing and LLM quality assurance

CrewAI
freemiumCrewAI is a leading open-source system for orchestrating autonomous AI agent teams (crews). Developers define agents with specific roles, goals, and tools, then combine them into crews that collaborate to complete complex tasks. With over 20,000 GitHub stars and rapid adoption, CrewAI has become the go-to system for building multi-agent AI systems that can research, write, code, and analyse in parallel.
Best for: Developers building multi-agent AI systems where specialised agents collaborate to complete complex research, writing, or analytical tasks
