Almost every product in this space is a tool you run on yourself. EvalQA is a second party that runs on you. That is not a feature difference, it is a structural one, and it decides which of these you need — often both.
The four categories
| Category | Who scores | Best at | Cannot do |
|---|---|---|---|
| Eval platforms Braintrust, LangSmith, Galileo, Patronus — SaaS tooling to build, run and track your own evals. |
You do. | Fast iteration during development; regression tracking across prompt versions. | Provide independence. You configure the test and the threshold, so the result inherits your assumptions. |
| Open-source tracing Langfuse, Phoenix, OpenLLMetry — self-hosted observability and scoring for LLM applications. |
You do. | Cost control, data residency, full pipeline ownership, no vendor lock-in. | Same independence limit, plus you now own the operational burden. |
| Native warehouse evaluation Snowflake, Databricks — evaluation built into the platform running the agent. |
The platform vendor does. | Zero integration cost, deep platform awareness, already in your bill. | Audit itself. A vendor paid on consumption cannot provide independent assurance of its own model to your audit committee. |
| Independent verification EvalQA — a contracted second party producing a signed assurance case. |
We do, and you can check the working. | Evidence that survives an audit committee; adversarial cases you would not have written. | Replace your development-time tooling. We are slower, narrower, and deliberately not in your inner loop. |
When you should not buy EvalQA
- You are still finding product-market fit for the agent. You need fast iteration, not a signed assurance case. Use a platform or open-source tracing; come back when the agent has consequences.
- Nobody owns the business definitions. Without a named Business Definition Owner, half our findings become
INDETERMINATEand you pay for ambiguity. We decline these engagements in writing — see scope. - The agent does not write SQL against a warehouse. That is the whole scope. A support chatbot or a coding assistant is someone else’s problem.
- You are on BigQuery or Redshift and need validated sensitivity. Both parse; neither has a benchmark partition yet. Coverage.
- You need a certification badge. We produce technical evidence, not statutory certification, and we explain why there is no badge.
The combination most teams actually want
Platform or open-source tooling in the development loop for speed, native warehouse evaluation for breadth because it is already paid for, and independent verification at the points where being wrong has consequences — a release gate, a regulated report, a board-level risk statement. These are not substitutes for each other, and a vendor telling you to replace all three with theirs is selling rather than advising.
Head to head
vs Braintrust
An eval platform you operate, compared with a second party you contract.
vs Langfuse
Self-hosted open source, and what independence actually buys on top of it.
vs native warehouse eval
The strongest argument for us, and the one we hold to a published kill rule.
Competitor capabilities in this category change monthly. These pages describe architecture rather than feature checklists for that reason, and each carries the date it was last reviewed. If we have described a product incorrectly, tell us and we will correct it — that is the same standard we ask of the vendors we evaluate.
