Agent Evaluation
The Best Ragas Alternatives
Compare Ragas alternatives by when to choose each option, when it is not ideal, and what to consider before switching.
When to consider an alternative
Choose Ragas when your agent's value depends on retrieval quality and you need metrics that isolate retrieval problems from generation problems.

Alternative tools
DeepEval
Best for Python teams that want to treat LLM/agent evaluation as a first-class testing discipline—with pytest-style assertions, CI integration, and built-in metrics.
Choose DeepEval if...
- pytest integration
- CI/CD evals
- regression testing
- agent testing
Not ideal if...
- teams not using Python
- projects that need a managed cloud platform only
Braintrust
Custom or external option
Choose Braintrust if...
- Choose this path if you need a narrow internal solution, a lower-level primitive, or a tool outside this directory.
Not ideal if...
- Not ideal if you still need a maintained product profile, docs trail, and comparable evaluation criteria.
Arize Phoenix
Best when the team needs observability that connects prompt debugging, agent traces, and evaluation in one open-source tool.
Choose Arize Phoenix if...
- agent tracing
- LLM observability
- evals
Not ideal if...
- teams that already have a paid observability contract
- projects where traces are only needed for debugging, not evaluation
What to consider
- Does the alternative solve the same agent layer, or is it a lower-level building block?
- Will switching improve observability, permission boundaries, state control, or evaluation coverage?
- Can the team validate the migration with one real agent task before replacing the current tool?
