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.
Turn agent traces into repeatable datasets, experiments, evaluations, and error analysis
4.1
Gentrace is an AI agent tracing and evaluation platform for organizing test cases, running experiments, deriving quality signals, and investigating failures across development and production traces.
Open-source tracing and evaluation for LLM, RAG, and agent applications
4.0
Phoenix gives teams OpenTelemetry-based traces, evaluations, experiments, datasets, and prompt tooling in a self-hostable project, but telemetry volume, sensitive content, evaluator validity, and operations remain buyer-owned.

When to switch
Look for an alternative if Galileo is too expensive, lacks the integrations you need, or is not strong enough for your primary workflow.
What to compare
Compare output quality, setup time, pricing limits, supported models, API access, and whether the tool fits your team’s existing systems.
Best next step
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.
