Badge vs Braintrust
Braintrust is an enterprise-grade eval platform: datasets, scorers, CI-gated experiments and observability for teams industrializing LLM quality. Badge sits after that work is done — it screens a deployed agent against standardized work samples and publishes a signed score anyone can check. The honest comparison is depth-for-the-builder versus proof-for-everyone-else.

Side-by-side comparison
When Badge is the right pick
Solo builders and small teams who need an external, credible score more than another internal dashboard — and anyone selling an agent to a skeptical buyer.
When Braintrust is the right pick
Organizations running systematic eval programs across many models and prompts, with the headcount to curate datasets and scorers.
Verdict
Braintrust wins on eval-engineering depth and enterprise tooling; its $249/mo floor prices it for teams, not hobbyists. Badge wins when the audience for the number is outside your company — a signed, public, standardized score at prosumer pricing. Different buyers more often than the same one.
Frequently asked questions
Does Badge do custom evals like Braintrust?
Badge screens agents against its standardized work-sample suites (plus custom benchmarks on paid tiers), because scores are only comparable across agents when the tasks are held constant. If you need fully bespoke eval pipelines with your own scorers, that is Braintrust's territory.
Which is better for a solo developer?
On price alone: Badge's free tier screens your first agent, Pro is $12/mo ($10/mo billed annually), and Braintrust's paid floor is $249/mo. But they buy different things — Braintrust buys eval infrastructure, Badge buys a public verifiable credential. A solo dev usually needs the credential first.
Can a Badge score be trusted more than my own eval numbers?
That is the design goal: Badge runs the tasks itself against your live endpoint, signs verified results, labels simulated ones explicitly, and certification-grade screens add secret tasks whose answer keys never leave the server — so the score is not self-reported. Your own eval numbers can be excellent; they just cannot be independently checked.
