| Self-Hosted | Helm + Docker (full stack) | Hybrid — data plane in your AWS account |
| LLM Firewall | Yes | No |

Why choose EvalGuard over Braintrust
- 300+ attack plugins and 100+ red-team strategies — Braintrust does evaluation, not security testing
- Full-stack self-hosting on Docker/Helm — Braintrust's self-hosting is hybrid: the data plane is yours, the UI, auth and metadata stay with them
- 5-layer runtime firewall — the Braintrust AI Proxy forwards Bedrock's guardrail signal but implements none of its own
Where Braintrust leads
- Braintrust publishes autoevals (MIT) — a widely used open scorer library, and the origin of several scorers other tools re-export
- The Braintrust AI Proxy is MIT and deployable on Vercel, Cloudflare, AWS Lambda or Express, with caching across 1,240 models
- Braintrust has polished eval UX and strong CI/CD integration
