FabricFabricExperiments

A governed, agent-native A/B testing platform for teams that need fast delivery, auditable decisions, and trustworthy warehouse-backed results.

Included

Everything needed for governed experimentation

GitOps authoring

YAML experiments, fx plan/apply, reconciled actions, and deterministic state transitions.

Tiny SDKs

A 1.78 KB gzipped web SDK with real-browser delivery tests plus a Node SDK for server assignment.

Governance

Roles, org tenancy, API keys, SAML settings, audit trails, signed manifests, and retention hooks.

Stats

Exposure-first attribution, aggregate endpoint, Bayesian summaries, and SRM/error guardrails.

Warehouse path

R2 ingestion and Databricks aggregation for production-scale exposure and conversion data.

Staging gates

M3/M4/M5 live-smoke scripts and a nightly workflow ready for seven-night validation.

Get started

Run locally first, then bring up staging

The fastest path is to prove the local spine, deploy the docs site, provision Cloudflare/Postgres/Vercel/Databricks/Temporal, then run live smokes nightly.
