## What it is
Kubeless is a Kubernetes-native serverless framework that lets you deploy functions as custom Kubernetes resources, with an in-cluster controller launching runtimes on demand and exposing them over HTTP or PubSub. It supports multiple runtimes including Python, Node.js, Go, Ruby, PHP, .NET, and Ballerina, leveraging Kubernetes for auto-scaling, API routing, and monitoring.

## Use cases
- deploy serverless functions on my own kubernetes cluster
- run function-as-a-service without vendor lock-in
- trigger functions from pubsub events on kubernetes
- expose small bits of code as http endpoints in k8s
- auto-scale functions using kubernetes resources
- self-hosted alternative to aws lambda

## When to choose
- you want a purely open-source, non-commercial FaaS on Kubernetes
- you prefer functions managed as Kubernetes custom resources
- you need multiple language runtimes with custom runtime support

## When to avoid
- you need an actively maintained project - Kubeless is no longer maintained by VMware
- you need support for Kubernetes versions beyond 1.15
- you want a commercially backed serverless platform
