Datasets and logs. Plus security and guardrails.
Braintrust does datasets, experiments, scorers, and production logging well. EvalGuard imports both — your log spans and your eval datasets — and adds red-team scans (300+ plugins), an LLM firewall, and a SOC 2 evidence engine on the same data. No sign-up needed to run your first eval.
Honest positioning
Where Braintrust stops, EvalGuard keeps going
Braintrust is a solid eval and observability tool — datasets, experiments, scorers, and logs done well. EvalGuard overlaps on all of that, then extends into the security, firewall, and compliance work you'd otherwise buy separately.
| Capability | Braintrust | EvalGuard |
|---|---|---|
| Datasets & experiments | Yes | Yes — versioned datasets + run history |
| Scorers / autoevals | Yes — 24 in autoevals | Yes — 200+ scorers (LLM-as-judge, pairwise, rubric) |
| Production logging & tracing | Yes | Yes — OTel trace ingest + cost attribution |
| Prompt playground & versioning | Yes | Yes — Prompt IDE + optimizer across 90+ providers |
| Human review / annotation | Yes | Yes — annotation queues with multi-reviewer assignment |
| AI proxy / gateway | Yes — Gateway (the older AI proxy is deprecated) | Yes — BYOK gateway, 15 proxied providers, similarity response cache |
| Red-team & security scans | Security / moderation judges in autoevals; no attack generator | Yes — 300+ attack plugins + 100+ adversarial strategies |
| LLM firewall / guardrails | No request-time blocking documented — evals and release gates | Yes — real-time input + output firewall |
| SOC 2 evidence automation | Not a documented product feature | Yes — live evidence engine + audit log |
| Self-hosting | Hybrid — data plane in your AWS account | Yes — self-host available |
Braintrust claims on this page were verified against their source — braintrust-sdk-python @ a82dc20e, autoevals @ b0e1055, bt-data-plane @ 2252fbd, plus braintrust.dev/docs raw HTML — on 2026-08-10. Capabilities move; check their current docs before you decide. “SOC 2 evidence automation” describes a product capability, not any vendor’s own certification status.
Migration paths
Braintrust is two things. So the move is two paths.
Braintrust owns your export end-to-end — we never touch your Braintrust account. Convert what you download with the EvalGuard CLI.
Observability — bring your log spans
Export your logs from Braintrust (the SDK span.export() / project-logs fetch, or the API), then convert them to neutral-shape spans — model, tokens, scores, and latency all map over.
Datasets & evals — convert and run
Export a Braintrust dataset, convert it to a runnable EvalGuard config, then run it — keyless on your machine, or on the EvalGuard cloud.
# JS: for await (const row of initDataset("My App", { dataset })) …
# Python: initDataset(project, dataset=...).fetch()npx @evalguard/cli import:braintrust braintrust-dataset.json -o evalguard.config.jsonnpx @evalguard/cli eval:local evalguard.config.json --provider echoThe echo provider runs the whole eval loop with no API key — perfect for validating the config before you spend a token. Swap in --provider openai (with your key) for real model calls, or run on the cloud for shared dashboards and run history:
