- eval datasets
- regression monitoring
Not ideal if...

- projects without enough runs to evaluate
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
Braintrust
Best when product and engineering teams need fast experiment comparison across prompts, models, and tool paths.
Choose Braintrust if...
- experiment-driven agent iteration
- LLM-as-judge eval workflows
- cross-team quality review
Not ideal if...
- teams that only need lightweight trace viewing
- workloads that cannot use a hosted eval platform
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?
