Go
Go is our choice for backend systems where performance, concurrency, and operational simplicity matter. Its small language surface and strong standard library help us build services that are fast in production and straightforward for teams to maintain.
Why we use it
- /Excellent performance with a small runtime footprint
- /Concurrency is built into the language
- /Simple codebases that are easier to review and maintain
- /Fast builds and straightforward production deployment
When we reach for it
- /High-throughput APIs and backend services
- /Microservices and distributed systems
- /Real-time or concurrency-heavy workloads
- /Systems where predictable performance matters
We keep Go services deliberately small and explicit. Interfaces are introduced where they improve boundaries, not everywhere by default, and dependencies remain easy to trace through the codebase.
For service-to-service communication we use typed contracts such as gRPC where appropriate, with structured logging, metrics, tracing, automated tests, and graceful failure handling built into the service from the start.
Common questions
What is Go (Golang) used for?+
Go is used to build scalable backend systems, APIs, cloud-native apps, CLI tools, and microservices. It's favored for its performance, simplicity, and built-in concurrency.
Is Go good for backend development?+
Yes, Go is excellent for backend systems thanks to its fast execution, memory safety, and powerful concurrency model using goroutines and channels.
How does Go handle concurrency?+
Go uses lightweight threads called goroutines and communication via channels, allowing efficient parallel processing without complex threading code.
Is Go better than Python or Node.js?+
It depends on the use case. Go offers better performance and concurrency for backend services, while Python and Node.js may be preferred for scripting or frontend-related stacks.
What frameworks are popular with Go?+
Popular Go frameworks include Gin, Echo, Fiber (for web APIs), and Cobra (for CLI tools). gRPC is also widely used with Go for efficient communication.
Is Go good for microservices?+
Yes. Go’s performance, fast startup, and small memory footprint make it ideal for building and scaling microservice architectures.
