The ultra-lightweight, multithreaded Redis alternative.
swcache is built from the ground up in Rust for maximum memory safety and blazing-fast performance — no garbage collector, no single-thread ceiling.
Why swcache
Engineered for the modern backend
Three core pillars set swcache apart from traditional in-memory caches.
Made in Rust
Memory safety without a garbage collector. Predictable, GC-free latencies and zero data races, guaranteed at compile time.
True Multithreading
Unlike Redis's single-threaded core, swcache scales efficiently across every CPU core to maximize throughput under load.
Ultra-Lightweight
A minimal memory footprint and tiny resource usage make swcache ideal for cloud-native, containerized, and edge environments.
Benchmarks
Redis vs swcache
Measured on an 8-core instance with a 50/50 GET/SET workload. swcache handles more throughput while consuming a fraction of the memory.
