Both Rust and Go have earned their place in modern backend development. At tria, we use both extensively — here’s our framework for choosing between them.
When to Choose Go
Go excels in scenarios where development speed and operational simplicity matter most:
- Microservices — Fast iteration, easy deployment
- API gateways — Excellent standard library for HTTP
- CLI tools — Single binary deployment
- Network services — Great concurrency model
When to Choose Rust
Rust shines when you need maximum performance and safety guarantees:
- Performance-critical services — Low latency, high throughput
- Systems programming — Filesystems, databases, runtimes
- Embedded and IoT — No runtime, minimal footprint
- Security-sensitive code — Memory safety without GC
Our Decision Framework
| Factor | Go | Rust |
|---|---|---|
| Development speed | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ |
| Runtime performance | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Memory safety | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Learning curve | ⭐⭐⭐⭐⭐ | ⭐⭐ |
| Ecosystem maturity | ⭐⭐⭐⭐ | ⭐⭐⭐ |
Parallels in Practice
Despite their differences, both languages share principles we value:
- Static typing with excellent tooling
- Built-in concurrency primitives
- Small, fast binaries
- Strong standard libraries
The right choice depends on your specific constraints. We’ve successfully used both — sometimes even together in the same system, with Go handling orchestration and Rust handling the performance-critical paths.
