Async HTTP/1.1 and HTTP/2.0

Built on Tokio + Hyper for maximum concurrency with non-blocking I/O.

Gzip + Brotli

Automatic response compression to slash bandwidth and boost load times.

Security Headers

Secure-by-default with rate limiting, IP allow/deny, and dotfile blocking.

TLS / HTTPS

rustls-powered TLS foundation. Auto TLS via ACME landing in v1.0.

PHP-FPM / FastCGI

Full FastCGI protocol support for PHP workloads with OpenLiteSpeed-like speed.

Virtual Hosts

Per-domain .toml configuration for multi-site hosting on a single server.

Prometheus Metrics

Built-in /metrics endpoint. Drop straight into Grafana dashboards.

ETag / 304 Caching

Client-side caching with ETag and Last-Modified for zero repeat downloads.
