26,192View on GitHubThis project is a Kubernetes serverless framework and OCI container function platform. It provides a system for deploying event-driven functions and microservices as compatible container images onto a Kubernetes cluster. The platform includes an event-driven function orchestrator that triggers executions via HTTP requests or message streams. It features an auto-scaling function manager that adjusts the number of active instances based on real-time demand and scales down to zero during inactivity. A background queuing system is included to process asynchronous tasks and maintain application re
OpenFaaS (this repo) is a mature, Kubernetes-native serverless framework that handles HTTP and event-driven function triggers, auto-scales to zero, supports container-based multi-language runtimes, integrates via CRDs, and provides observability — directly matching your requirements for a self-hosted FaaS platform on Kubernetes.

apache/openwhisk
6,779View on GitHubOpenWhisk is a serverless cloud platform designed for deploying and executing stateless functions in response to API calls or events. It serves as a complete serverless stack, providing an API gateway for functions, a function-as-a-service runtime manager, and an event-driven workflow engine. The platform distinguishes itself through a polyglot execution model that supports multiple language runtimes and allows for the creation of custom runtimes using Docker containers. It enables complex logic through function orchestration and composition, allowing multiple functions to be chained into seq
OpenWhisk is a mature, open-source FaaS platform designed to run on Kubernetes, supporting polyglot runtimes, event-driven triggers, auto-scaling (including scale-to-zero), and observability—precisely the self-hosted serverless computing setup you need.

6,847View on GitHubKubeless is a Kubernetes-native serverless framework that deploys and runs stateless functions as custom resources managed by an in-cluster controller. It functions as a Function-as-a-Service platform, launching function runtime pods on demand and scaling them to zero when idle to optimise resource usage. Functions are invoked automatically through HTTP requests or a publish-subscribe messaging bus, enabling event-driven execution for workloads and microservices. The platform supports running functions written in Golang, Python, Node.js, Ruby, PHP, .NET, and Ballerina, with the ability to add
Kubeless is a Kubernetes-native FaaS platform that runs functions as custom resources with scale-to-zero, HTTP/pub-sub triggers, and support for multiple languages, directly matching the core requirements, though it lacks a built-in function registry and built-in observability tooling.

fission/fission
8,863View on GitHubFission is a function-as-a-service platform and serverless framework for Kubernetes. It manages the lifecycle and execution of code snippets as serverless functions, providing an orchestrator that triggers these functions based on HTTP requests, message queues, or scheduled events. The platform features a cold-start optimized runtime that utilizes warm container pools and dynamic loaders to achieve millisecond execution. It includes a native autoscaler to adjust the number of function instances based on real-time traffic demand and supports canary release testing to split incoming traffic bet
Fission is a self-hosted FaaS platform designed specifically for Kubernetes, with event-driven triggers (HTTP, queues, schedules), built-in autoscaling (including scale-to-zero via warm-pool optimization), multi-language runtimes, and Kubernetes-native deployment — directly matching the request for managing serverless functions on your own cluster.

nuclio/nuclio
5,730View on GitHubNuclio is a high-performance serverless framework designed for Kubernetes that automatically executes user functions when events arrive from HTTP endpoints, message queues, or streaming data platforms. It processes hundreds of thousands of events per second per function instance through efficient parallel workers, and can allocate functions to run on either CPU or GPU hardware to match workload requirements for data processing or machine learning tasks. The platform scales function instances down to zero when idle and wakes them on demand based on incoming event load, while providing an event
Nuclio is a Kubernetes-native serverless framework that auto-scales function instances to zero, triggers from HTTP and streaming sources, and supports CPU/GPU execution—directly meeting the need for a self-hosted FaaS platform with event-driven triggers and scale-to-zero.

26,092View on GitHubOpenFaaS is a serverless function platform that provides a container-native framework for deploying and managing event-driven code. It functions as an abstraction layer over container orchestrators, allowing developers to package code into scalable functions that run across Kubernetes clusters or edge computing environments. The platform distinguishes itself through a developer-centric runtime that utilizes standardized language templates and automated build pipelines to simplify the creation of container images. It features a central API gateway that manages request routing, authentication,
OpenFaaS is a mature, container-native FaaS platform designed for Kubernetes that natively supports HTTP and event-driven triggers, scale-to-zero, multi-language runtimes via templates, built-in container image management, and Prometheus-based observability — exactly matching the self-hosted serverless platform this search requires.
