Show HN: Cygnus – A fast, lightweight self-hostable serverless runtime and PaaS

2 months ago

Self-hosted serverless for Bun and Node with kernel-sandboxed cages and sub-100ms revival.
Full Node compatibility via namespaces and seccomp, no container runtime.
Single Rust binary handles TLS, SNI routing, and proxy with io_uring splice.
Real egress networking using veth and nftables, no userspace proxy.
Three deployment methods: dashboard, Git push with previews, and CLI.
Instant blue-green rollback with five last deployments kept on disk.
Scale to zero, idle apps reaped after 10 minutes, cold starts in 15-45ms.
