Lampyr

Small services.
Bright starts.

Run familiar applications in short-lived Hyperlight microVMs. Lampyr brings hardware-isolated activation, scale-to-zero execution, and a compact deployment workflow to Kubernetes.

A smaller path from source to isolated execution.

Familiar applications

Use ordinary HTTP servers or supported language adapters for Node.js, Python, Go, Rust, and .NET.

Hardware isolation

Application execution stays inside Hyperlight microVMs with immutable, pre-admitted configuration.

Idle execution reaches zero

No service-specific running instance is required while idle; shared infrastructure remains ready.

Capability-based execution

Pre-admitted policies define network and filesystem access. Grants authorize execution within resource and capacity limits.

How a request is handled

Ingress routes the request, fiber-router finds the home admitted for its revision, and fiberd restores a prepared microVM. When work finishes, that instance disappears.

Follow a request through LampyrA request begins with a user, travels through ingress, fiber-router, and fiberd, then lights a restored service microVM.

Build from source, then start locally.

The current release workflow does not publish downloadable CLI or platform archives. Start with the verified repository path and a local Kind cluster.

Supported languages and runtimes

Protocol coverage varies by runtime. Use the compatibility matrix to choose a template and understand its limitations.
