• Search

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

• Monitoring

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

• Backend

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

Distributed event streaming platform that stores data as a durable, replayable log, built for high-throughput real-time pipelines rather than traditional point-to-point queuing.

• Backend

• DevOps

CNCF-graduated log collector that unifies data collection from many sources into a single, structured logging layer.

• Monitoring

Distributed, ordered key-value store with strong ACID transaction guarantees, designed as a reliable storage substrate for other systems.

• Database

Open source platform for monitoring and observability, letting you query, visualize and alert on metrics.

• Monitoring

Horizontally scalable log aggregation system, designed by the Grafana team to pair with Prometheus-style metrics using the same labels.

• Monitoring

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

• API

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

• DevOps

Distributed POSIX filesystem that stores data on object storage like S3, combining familiar filesystem semantics with cloud-scale storage.

• Storage

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

• API

Lightweight, distributed block storage for Kubernetes, designed to be simple to deploy and operate compared to heavier storage systems.

• Storage

CNCF dashboarding tool for visualizing observability data, built around portable, version-controllable dashboard definitions.

• Monitoring

Open source systems monitoring and alerting toolkit with a dimensional data model and powerful query language.
