Rust in Production: Who Uses It and Why

Rust has moved from a systems programming niche to a mainstream production language. As of 2025, 48.8% of organizations report non-trivial use of Rust — a 10-point jump from 38.7% in 2023. The language's zero-cost abstractions, memory safety without garbage collection, and fearless concurrency model have made it the default choice for performance-critical and safety-sensitive software.

Where Rust Excels in Production

Infrastructure & Networking

Cloudflare rebuilt its entire core proxy layer (FL2) in Rust, replacing Nginx/LuaJIT. The result: 25% performance improvement and elimination of memory-safety bugs. Amazon uses Rust for Firecracker (the microVM powering Lambda and Fargate) and Bottlerocket OS.

Cross-Platform Applications

1Password consolidated all business logic — cryptography, database, server communication — into a single Rust core library shared across macOS, iOS, Windows, Android, Linux, and browser extensions. This approach cut platform-specific bugs dramatically.

Real-Time Systems

Discord rewrote its Read States service from Go to Rust, eliminating garbage-collection latency spikes and achieving consistent sub-millisecond response times at scale. Figma ported its multiplayer synchronization engine from TypeScript to Rust, achieving 10x faster serialization.

Operating Systems & Kernels

Google reports that 21% of all new native code in Android 13 is Rust (~1.5 million lines). Microsoft has integrated Rust into the Windows kernel and multiple Azure services including IoT Edge and Azure Data Explorer.

The Rust Foundation Ecosystem

The Rust Foundation, established in 2021, counts AWS, Google, Microsoft, Huawei, and Mozilla as founding platinum members. Gold and silver members include Shopify, Meta, Toyota, Arm, and dozens more — reflecting adoption well beyond Silicon Valley into automotive, manufacturing, and telecommunications.
