Alternatives
The right alternative depends on what you are replacing: price, AI quality, integrations, enterprise controls, or workflow focus. Start with the closest competitors, then use the related guides to narrow the decision.
Ranked by editorial fit, category overlap, and structured relationships.
Open-source evaluation and security testing for prompts, models, RAG systems, and agents
Promptfoo brings repeatable evals, model comparisons, assertions, red teaming, and CI gates to AI development, but test-set quality, judge calibration, sensitive traces, and remediation ownership determine its value.
Evaluate RAG, prompts, and agent behavior
Ragas is an open-source evaluation framework for RAG systems, prompts, workflows, and agents using configurable datasets and metrics.
Look for an alternative if DeepEval is too expensive, lacks the integrations you need, or is not strong enough for your primary workflow.
Compare output quality, setup time, pricing limits, supported models, API access, and whether the tool fits your team’s existing systems.
Shortlist two options, run the same real workflow through both, and keep the one that reduces rework rather than the one with the longest feature list.
Write down the specific reason to switch and the capabilities you must preserve. Test the same inputs in your current workflow and two alternatives. Count corrections, setup, paid seats, usage charges, and migration effort; a lower subscription alone does not establish a saving.
Verify export and reimport on a small sample, check retention and deletion terms for the plan you will use, and keep a backup and manual fallback until the replacement works. Confirm billing cancellation separately from deleting an account.
