The leading service mesh for Kubernetes, adding traffic management, security, and observability to microservices without changing application code.

• DevOps

Lightweight service mesh for Kubernetes focused on simplicity and low resource overhead, a genuine alternative to Istio.

• DevOps

High-performance proxy built for cloud-native applications, serving as the foundational data plane for many modern service meshes and API gateways.

• DevOps

Cloud-native chaos engineering platform for Kubernetes that injects controlled faults - pod, network, I/O, and more - to test how a system actually behaves under failure.

• Testing

Dynamic, high-performance API gateway built on NGINX and etcd, adding hot-reloaded plugins, canary releases, and AI-traffic routing on top of traditional gateway features.

• API

Portable runtime that gives microservices building blocks - state management, pub/sub messaging, service invocation, and workflow - over a sidecar API in any language.

• Backend

High-performance, open-source RPC framework that lets services call each other's functions directly across languages and networks.

• API

CNCF distributed tracing platform for visualizing request flows across microservices, pinpointing exactly which service or call is responsible for latency or errors.

• Monitoring

Cloud-native API gateway that handles routing, load balancing, authentication, and traffic management for microservices, APIs, and LLM/MCP traffic.

• API

Kubernetes-native Java framework designed for fast startup times and low memory footprint, tailored for containers and serverless.

• Backend

Open-source backend platform providing authentication, databases, storage, functions and realtime APIs, self-hosted or as a managed cloud service.

• Backend
• Database
• Authentication & Security

Open framework for building an internal developer portal, unifying a company's services, infrastructure, and documentation behind one searchable software catalog.

• Developer Tools

API-first, headless identity and user management server for cloud-native applications, covering login, registration, recovery, and profile management.

• Authentication & Security

Open source backend consisting of an embedded SQLite database, authentication, file storage and a realtime API in a single executable.

• Backend
• Database

Application performance monitoring (APM) platform providing distributed tracing, service topology, and metrics in one system.

• Monitoring

Self-hosted uptime and status monitoring tool with a reactive dashboard, covering HTTP, TCP, DNS, ping, Docker containers, and more.

• Monitoring

Load testing and network measurement tool built for microservices, reporting detailed latency percentiles under sustained load.

• Testing

Lightweight, self-hosted Git service with issue tracking, pull requests and CI integration.

• Developer Tools

Workflow automation platform that lets you connect apps and services with a visual, node-based editor.

• Automation
• Developer Tools

General-purpose, CNCF-graduated policy engine for enforcing authorization, compliance, and configuration rules as code across microservices, APIs, Kubernetes, and CI pipelines.

• DevOps

Relationship-based authorization engine inspired by Google Zanzibar, for modeling and enforcing fine-grained access control as a standalone service.

• Authentication & Security

Daemonless container engine that runs, builds, and manages containers as a drop-in Docker alternative, without a background root service.

• Developer Tools

Mature, widely deployed message broker for decoupling services with reliable queues, routing, and pub/sub messaging across AMQP, MQTT, and STOMP.

• Backend

Kubernetes storage orchestrator that automates deploying, managing, and scaling storage systems like Ceph as native Kubernetes services.

• Storage

Open-source, self-hosted authentication core service offering passwordless, social, and email/password login as an alternative to Auth0 or Firebase Auth.

• Authentication & Security

Cloud-native identity and access management platform with multi-tenancy, SSO, MFA, and OIDC/SAML support, usable self-hosted or as a managed service.
