The Rust-Powered
Edge Gateway Built for
Modern Infrastructure
Lock-free. Lightning-fast. Protocol-agnostic.
High-performance API gateway engineered in Rust. Zero mutex blocking on request paths, 51 built-in plugins, and full multi-protocol support from HTTP/1.1 to HTTP/3 QUIC.

Ferrum Edge is engineered from the ground up for speed and reliability — no compromises, no garbage collection pauses, no mutex contention on the request path.
Lock-Free Architecture
ArcSwap atomic reads + DashMap concurrent maps keep every hot path free of mutex blocking. Config updates are atomic swaps — zero downtime, zero stalls.
51 Built-in Plugins
Auth, rate limiting, AI/LLM, observability, transformation, routing, WebSocket, gRPC — all available as first-class plugins with per-route priority ordering.
Multi-Protocol Support
HTTP/1.1 through HTTP/3 QUIC, WebSocket, gRPC, TCP, and UDP — all with optional TLS/DTLS. One gateway, every protocol your stack needs.
AI/LLM Gateway Ready
Token metrics, prompt shield, request guard, and token rate limiter plugins purpose-built for LLM API proxying. Control costs and protect your AI endpoints.
Zero-Downtime Reloads
Push config changes via the Admin API. Ferrum Edge performs an atomic ArcSwap — in-flight requests complete uninterrupted while new requests immediately see the updated config.
Distributed CP/DP Mode
Scale with a dedicated Control Plane pushing config to multiple Data Plane instances via gRPC streaming. Ideal for geo-distributed and high-availability deployments.
Four Operating Modes
From a single-node file-based config to a globally distributed Control Plane / Data Plane architecture.
File Mode
YAML config file. Perfect for development, single-node, or GitOps-style deployments.
Database Mode
PostgreSQL, MySQL, SQLite, or MongoDB. Admin API for dynamic config management.
Control Plane
Central hub that reads from DB and pushes config to Data Planes via gRPC streaming.
Data Plane
Stateless request processors. Receive config from CP. Auto-reconnect and local caching for resilience.
Built to Be Invisible
Ferrum Edge delivers 102,183 RPS on HTTP/1.1 and over 108K on HTTP/2 and raw TCP — tested on Apple Silicon with 200 concurrent connections. The goal: your backend is your bottleneck, not your gateway.
- 102,183 RPS on HTTP/1.1 (Apple Silicon, 200 concurrent)
- 101,317 RPS on HTTP/1.1 + TLS
- 108,841 RPS on raw TCP proxy
- 103,830 RPS on WebSocket
- Lock-free O(1) route lookup, O(1) plugin execution
Rust-Native. Not Wrapped. Not Ported.
Unlike gateways that bolt Rust on top of a C or Go core, Ferrum Edge is built in Rust from the ground up. Memory safety without GC. Fearless concurrency without mutexes. The ArcSwap + DashMap combination means your request thread never waits for a config lock.
51 Plugins, Ready to Go
Every capability you need, built in. No marketplace hunting, no compatibility nightmares.
