Features

Built for Enterprise Scale

Everything you need to compile C++ to any platform without the infrastructure overhead.

Cloud-Native Builds
No local Docker installation required. Upload your project and get compiled binaries back in seconds.
Multi-Platform Support
Build for WebAssembly, Browser, Node.js, Android, and iOS — all from a single request.
Build Speed Tiers
Choose Normal (1x), Fast (2x), or Extreme (3x) build speeds. Higher tiers use more credits but finish faster.
Pay-Per-Second Billing
Only pay for actual build time. No idle costs, no monthly minimums. Full transparency on usage.
Enterprise Security
Passwordless magic link auth, project-scoped API keys, and isolated ephemeral build containers.
Project Management
Organize builds into projects. Scope API keys to specific projects for fine-grained access control.
API-First Design
RESTful API with rate limiting for seamless CI/CD integration. Automate your build pipeline with simple HTTP requests.
High-Performance Infrastructure
Powered by Fly.io with 4 CPU cores and 8GB RAM per build. Distributed globally for minimal latency.
Full cpp.js Support
Complete compatibility with cpp.js ecosystem. Supports all archive formats: .zip, .tar.gz, .tgz, .7z, and more.
