Real-Time SSE Push

Flag updates propagate instantly via Server-Sent Events. Zero polling. Redis Pub/Sub fan-out across all API nodes.

28ns

1-rule eval

Granular Targeting

Percentage rollouts, user attribute overrides, SemVer matching, and contextual rules — all evaluated locally in-memory.

Bayesian A/B Testing

Multi-Armed Bandit workers run Monte Carlo simulations via Beta distributions, autonomously shifting traffic toward winning variants.

100% Self-Hosted

Deploy in your VPC or Kubernetes cluster. No PII or evaluation context ever leaves your network. GDPR-ready by design.

SSRF-Safe Webhooks

Outbound triggers for Slack, Teams, and CI/CD with Polly-powered retries, exponential backoff, and Dead-Letter Queues.

HFT-Grade Latency— Mean ≈ P100 — no tail latency spikes

Enterprise RBAC— Org → Project → Environment isolation

SRM Detection— Chi-Square test catches assignment bugs

HFT-grade evaluation latency

Compiled expression trees and zero-allocation contexts deliver nanosecond evaluation with no GC pressure. Mean ≈ P95 — no tail latency spikes.

Intel Core i7-14700K, 20 Physical Cores, .NET 10.0 Release (AOT)

All scenarios: 0B allocated

Method	Scenario	Mean	StdDev	P95	Alloc
Evaluate_NoRules_AOT	Baseline	6.73 ns	0.02 ns	6.76 ns	0B
Evaluate_1Rule_AOT	Typical	28.13 ns	0.08 ns	28.24 ns	0B

TrackEvent_10Rules_AOT	Metrics	45.52 ns	0.15 ns	45.77 ns	0B

Suitable for High-Frequency Trading infrastructure.
Mean latency tracks P95 within 1% — the evaluation path has deterministic, jitter-free performance with zero garbage collector pauses. Every scenario shows 0 bytes allocated.
