Fission Pricing, Features & Alternatives

Fission is an open source serverless framework for Kubernetes. It lets developers write short-lived functions in Python, Node.js, Go, C#, PHP, or Java and map them to HTTP requests or other event triggers, without needing to build containers or manage registries.

One of Fission’s standout features is its pre-warmed container pool, which keeps cold-start latencies around 100ms. Functions deploy instantly with a single CLI command, and declarative specs allow entire applications to be version-controlled and recreated from source.

Fission integrates with Fluentd for logging, Prometheus for metrics, and Istio for service mesh capabilities. It is licensed under Apache 2.0 and runs on any Kubernetes cluster, whether on a laptop, in a public cloud, or in a private data center.
