SpinUPCloud-functions for Spin, on Kubernetes

Build and deploy WebAssembly HTTP functions with a Monaco editor and one click. Runs on any Kubernetes cluster with SpinKube.

Quick start

Architecture

Applications, not just functions

Group related functions into an Application. One Spin runtime, one pod, N HTTP triggers — sub-millisecond per-request instantiation.

Multi-language builders

Go, JavaScript, TypeScript, and Rust. Each builder is a container image that runs as a Kubernetes Job on demand.

OpenTelemetry-native observability

The SpinAppExecutor forwards traces to an in-cluster OTel Collector. A spanmetrics connector derives per-function RED metrics; the UI plots them from the control plane.

SSO (OIDC) ready

Bring any OIDC provider. No local users; identity flows from your IdP to every /api/* call.
