Galea vs. LangSmith vs. Braintrust vs. Arize vs. Maxim

Five tools look at the same agent workflow. Four say clean. Galea catches the fabricated citation. Here's why the approaches differ.

Benchmarked against real agent trajectories

We tested Galea against 150 agent trajectories from tau-bench (Sierra Research) — real customer-service agents handling exchanges, cancellations, and bookings. Zero configuration. No eval rules written. Just ingest and investigate.

95% Detection rate Failed runs flagged automatically
0% False positive rate Clean runs never flagged as errors
80% Category alignment Correctly identifies failure type
0 Eval rules written Heuristic layer only — no LLM, no config

Competitors require you to write every eval rule by hand — and still can't tell you why a run failed. Galea's heuristic investigator detects tool loops, risk threshold violations, baseline anomalies, and run failures out of the box. The LLM layer (optional) adds priority-scoped correctness checks and natural-language narrative.

vs LangSmith

LangSmith shows spans returned OK. Galea investigates whether what happened was correct.

vs Braintrust

Braintrust says "5/5 passed." Galea says "the citation was fabricated — here's the agent at fault."

vs Arize

Arize tracks model drift. Galea investigates whether the workflow produced a correct, safe result.

vs Maxim

Maxim evaluates in a sandbox before deploy. Galea is the watchdog that catches what evaluation missed — in production.

Galea is a watchdog, not a test harness

Eval tools test whether your agent can produce good outputs. Galea watches whether it actually does — on every production run, scoped to your priorities, with blame attribution when something goes wrong. Quality isn't a score. It's continuous investigation.
