Common questions
Is DeepEval free to use?
DeepEval is open source and free to run yourself. You still pay whichever model provider you point it at, and this tutorial is free with no signup.
Do I need to know Python to use DeepEval?
Basic Python is enough. Functions, dictionaries and imports cover most of what DeepEval asks of you.
When should I not use DeepEval?
When something else in evals and testing fits the job better. The others in that group are listed below.
Lessons for DeepEval are being written. Meanwhile the Claude Code tutorial covers the same ground: state, tools, loops, memory and human approval. Most of it carries straight over.
