Golang has emerged as a powerful programming language since its creation at Google in 2007. Born from the frustration with existing languages, Go offers a refreshing alternative for developers building large-scale applications.
What makes Go stand out? Its simple syntax, efficient performance, and built-in concurrency support tackle the exact problems that large tech companies face daily.
Let’s explore the top companies that have embraced Golang and discover why they made the switch.
Before diving into specific companies, let’s understand what makes Go so attractive for businesses:
Speed and Performance
Simplicity and Maintainability
Concurrency Made Easy
Perfect for Modern Architecture
As Go’s creator, Google naturally leads the pack in adoption. The tech giant uses Go for numerous internal projects, including:
Google designed Go specifically to solve the scalability and maintenance challenges faced by their engineering teams. The language helps Google manage codebases with millions of lines while maintaining fast build times.
Uber relies on Go for its critical geofence service, which determines driver availability and pricing based on user location.
The results speak for themselves:
According to Uber’s engineering team, Go’s performance under high load and reliability in production have exceeded expectations, with downtime issues typically coming from third-party libraries rather than Go itself.
The popular streaming platform uses Go for its most demanding systems. When you’re handling millions of concurrent video streams and chat messages, performance matters.
Twitch achieved a remarkable 20x improvement in garbage collection after switching to Go. This directly translates to smoother streaming experiences and more reliable service during peak usage times.
The company cites Go’s simplicity, security, and readability as key factors in managing their complex real-time systems.
Facing scaling challenges with their Python codebase, Dropbox migrated critical infrastructure components to Go.
To solve the lack of depth in Go libraries for their specific needs, Dropbox built custom libraries for:
This investment paid off with faster performance, reduced resource usage, and better scalability for their cloud storage platform.
This cloud-based email service processes over 500 million messages daily using Go as its primary programming language.
SendGrid faced challenges with:
Go’s efficient concurrency model solved these issues while reducing maintenance costs. The switch allowed SendGrid to handle increasing message volumes without proportional infrastructure growth.
SoundCloud describes Go as a “WYSIWYG language” – what you see is what you get. This clarity helped them move beyond limitations in their Ruby on Rails stack.
The music streaming platform now runs six services completely written in Go, gaining:
This video platform improved its API automation testing using Golang. The switch provided:
Dailymotion found that Go’s performance characteristics were particularly well-suited for handling the high-throughput demands of video content delivery.
The streaming giant uses Go in its content delivery systems to handle massive scale requirements efficiently.
Netflix’s adoption focuses on:
Go’s small memory footprint and fast startup times make it ideal for Netflix’s containerized deployment strategy.
The payment processing leader employs Go to handle critical transaction systems where performance and security are non-negotiable.
PayPal benefits from:
The switch has helped PayPal process transactions more quickly while maintaining their strict security requirements.
The financial services company uses Golang for backend systems that require both reliability and speed.
American Express values:
The company has gradually expanded its Go usage as developers experience productivity gains and operational benefits.
These companies didn’t switch to Go on a whim. They’re seeing tangible benefits:
Development Speed
Resource Efficiency
Deployment Advantages
Reliability Improvements
Go shines brightest when:
The companies above demonstrate that Go works particularly well for:
