DFINITY
A leading blockchain technology company building the Internet Computer, a revolutionary decentralized computing platform that extends the internet with smart contract functionality.
"Namespace is an impressive team offering a great product; a year after initial contact we are happier than ever to have made the decision to use namespace infrastructure."
The Challenge
Aging Hardware
Self-hosted macOS hardware fleet (2018-2019 Intel Macs) was becoming outdated and unreliable.
Build Reliability Issues
Average full rebuilds were frequently failing to complete successfully.
Maintenance Burden
Significant engineering time was being consumed by macOS runner maintenance and troubleshooting.
Limited Scalability
On-premises infrastructure couldn't scale to meet growing development team needs.
Why DFINITY Chose Namespace
Seamless GitHub Actions Integration
Simple setup process with minimal migration effort from existing workflows.
Advanced Caching
Built-in Bazel cache support for dramatically faster builds.
Command Line Flexibility
Ability to spin up instances directly from command line for debugging and testing.
Multi-Architecture Support
Access to both AMD64 and ARM64 Linux runners alongside macOS options.
Build Time Transformation
Self-hosted Runners
Best-case builds (often failing)
Namespace
Best-case builds (reliable)
Plus improved reliability with ~20min average full rebuilds
