Pulse

Modern distributed applications require dynamic feature flagging that evaluates in micro-seconds without introducing network round-trips for every check. Standard SaaS flagging options are expensive and leak sensitive user metadata outside the firewall. We needed a self-hostable, enterprise-grade flagging service with zero-latency local evaluation, complex nesting rules, and consistent hashing for sticky target rollouts.

Pulse enables engineering teams to manage hundreds of feature flags across multiple environments with microsecond-level local evaluation overhead. The built-in consistent hashing algorithm guarantees sticky rollout allocations (e.g. 10% canary release) with zero user drift, while the real-time SSE sync pipelines propagate changes globally in under 200ms.
