Flagura, a Feature-Flag Switchboard With a Live Benchmark

Field notes

Flagura separates flag evaluation from its control plane: the page says targeting schemas are compiled and evaluated inside the application process, while updates travel through a Server-Sent Events stream. Its operating model includes a visible stale-flag report, two-person production approvals, deterministic FNV-1a bucketing, and an automatic rollback threshold stated as greater than 1.5% errors. The site lists Go, TypeScript, Python, Rust, and cURL integrations, with SQLite for single-node use and PostgreSQL for distributed deployments.
