The decisioning system
for teams shipping at scale.

The adaptive optimization engine that serves the best-performing variant on every request — and gets smarter from what happens next.

CONSOLE

Every experiment, one screen.

Live throughput, traffic allocation, and confidence per variant — watch qbrix converge from the console, no dashboards to babysit.

01 / 04Homeevery experiment, one screen — live throughput, allocation, top-arm reward.
PRODUCT

Built for production.
Designed to disappear.

Connect qbrix with a single API call and forget it's there. Multi-tenant, secure, and self-optimizing from request one.

THE ENGINEhow qbrix decides

Real-time adaptive

Traffic moves to what's working. No manual analysis, no waiting for significance — it self-adjusts in minutes.

Self-optimizing

qbrix reads your data and matches the best-fit algorithm to it — then keeps re-checking as it learns, switching automatically when your data shifts.

Personalized at request time

Per-user features choose the best variant. New visitors and power users see what works for them — not what works on average.

THE PLATFORMeverything else, handled

Multi-tenant & RBAC

Full tenant isolation, three-role access control, and a complete audit trail — on by default.

Production scale

Stateless, horizontally scalable selection with zero database calls per decision. The hot path never touches training.

Feature gates

Progressive rollouts and per-segment targeting from the same SDK.

Every decision, in the open.

Every selection, outcome, and policy switch — streamed the moment it happens. No black box, no nightly wait.
