Launched on December 16, 2025, public.swaplab.net was built with a simple goal: to help beginner and professional developers—especially those with hardware limitations—compile and test their mobile app projects effortlessly.
Over a year later, the service has been incredibly well-received by the community. The metrics from our public infrastructure speak for themselves:
It is important to acknowledge that the real hero behind the scenes handling this heavy computation is GitHub's infrastructure. The SwapLab service essentially acts as a "smart bridge" that orchestrates and triggers these workflows.
Once the Docker image starts running and the build process begins, our engine streams the live logs securely via WebSocket directly to your browser session in real-time.
Whether you use the public (anonymous) version or this Private Builder, our service is completely free. There are no subscriptions, no premium tiers, and no hidden fees. These computing resources are provided "as is" to support the open-source ecosystem and the developer community.
To understand the limitations and fair use rules, please read our Privacy Policy & Terms of Service.
