Agent Tracing
The Best Traceloop Alternatives
Compare Traceloop alternatives by when to choose each option, when it is not ideal, and what to consider before switching.
When to consider an alternative
Choose Traceloop when your SRE stack is already OpenTelemetry-centric and LLM traces should look like normal service telemetry.

Alternative tools
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
Langfuse
Best when teams want self-hostable observability with datasets, scores, and prompt management in one stack.
Choose Langfuse if...
- self-hosted agent tracing
- production eval loops
- prompt versioning with traces
Not ideal if...
- teams that only need a hosted LangChain-native workflow
- projects with no appetite to operate observability infrastructure
custom OpenTelemetry collector
Custom or external option
Choose custom OpenTelemetry collector 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.
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?
