Alternatives toCygnus

Best alternatives to Cygnus in 2026

Serverless platforms like AWS Lambda are convenient but hand your code and your bill to someone else's cloud. Cygnus is for people who want the same experience — deploy code, have it scale to zero when idle, and spin back up instantly on request — but running on their own infrastructure, without becoming a Kubernetes expert first. Cygnus achieves this by using kernel-level sandboxing (Linux namespaces, seccomp, cgroups v2) instead of Docker-style containers, which is what lets it hit sub-100ms cold starts (with a stated goal of 30ms at the median) rather than the multi-second cold starts typical of container-based platforms. It runs Node.js and Bun applications, including native addons, and offers three deployment paths: a dashboard, Git push with automatic PR preview environments, or a CLI. Under the hood, a Rust daemon handles TLS termination and proxying via io_uring, real networking is implemented with veth and nftables rather than a userspace proxy, and idle apps go to disk-only state for true scale-to-zero. It's AGPL-3.0 licensed and open source, with a live demo available at console.cygnus.run.
