River is a reverse proxy application written in Rust, built on Cloudflare's Pingora library and developed under ISRG's Prossimo initiative to promote memory-safe internet infrastructure. It offers load balancing, rate limiting, KDL-based configuration, and planned WASM-based scriptability.

Use cases

• replace nginx with a memory-safe reverse proxy
• load balance traffic across backend services
• rate limit incoming HTTP requests at the edge
• proxy traffic with better connection reuse than nginx
• script proxy behavior with WASM plugins
• deploy a Rust-based edge proxy for security-sensitive infrastructure

When to choose

• you want a memory-safe alternative to nginx or other C/C++ proxies
• you need high-performance load balancing and connection reuse
• you value Rust safety guarantees at the network edge
• you want simple file-based (KDL) proxy configuration

When to avoid

• you need production stability - the project explicitly offers no stability guarantees
• you need the full mature feature set of nginx or HAProxy today
• you require extensive plugin ecosystems or long-term support
• you need battle-tested behavior under complex production traffic
