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.
| Galea | LangSmith | Braintrust | Arize | Maxim | |
|---|---|---|---|---|---|
| What it is | Investigation watchdog | Trace viewer | Eval suite | ML observability | Eval + simulation |
| Investigates each run | ✓ | ✗ | ✗ | ✗ | ✗ |
| Customer-specific priorities | ✓ | ✗ | ✗ | ✗ | ✗ |
| Blame attribution | ✓ | ✗ | ✗ | ✗ | ✗ |
| Fabricated citation detection | ✓ | ✗ | ✗ | ✗ | ✗ |
| Incident → durable eval | ✓ | ✗ | ~ | ✗ | ~ |
| Signed audit export | ✓ | ✗ | ✗ | ✗ | ✗ |

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.
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.
