In their own words
Middleware
Middleware is a hybrid observability platform for detecting and resolving issues across infrastructure, application performance, and real-user monitoring. Its listed coverage includes infrastructure monitoring, logs, metrics, distributed tracing, database monitoring, synthetic monitoring, browser testing, and LLM observability. The AI SRE Agent and OpsAI capabilities include root cause analysis, automatic issue detection, faster issue solving, and automatic PR generation. The Free Forever plan costs nothing and includes up to 100GB of data, 1k RUM sessions, 20k synthetic checks, 10 browser test runs, and 2 million OpsAI tokens, with 14-day retention and community support. Pay As You Go costs $0.30 a month, billed according to use, with default 30-day retention. Middleware lists 450+ integrations and a Public API. It runs on Android, iOS, Linux, macOS, web, Windows, and API. The company says it encrypts customer data in transit and at rest using TLS 1.2+ and AES-256.
Radar
Radar is an open-source Kubernetes interface for platform engineering teams and AI agents. It brings topology, events, Helm, GitOps, image internals and audits into one interface. Its live graph shows Deployments, Services and Ingresses with traffic, TLS health and cross-namespace dependencies. Radar can run locally as a single binary with a kubeconfig or in-cluster through Helm, and desktop apps are available for macOS, Linux and Windows. Built-in integrations include Argo, Flux, Cilium, Istio, Karpenter, KEDA, Crossplane, cert-manager, OpenCost, Kubecost, Prometheus, Trivy and Velero. Radar OSS is free forever, supports unlimited clusters and nodes, and sends no cluster data out, though it makes one anonymous version check that can be blocked. Cloud Free supports up to three clusters and 100 hosted investigations per month. Paid plans start at $149 per cluster per month for Team; Enterprise costs $299 per cluster per month. Cloud offers AI investigations and alerts to Slack or webhooks. It streams viewed resources, events and logs through its control plane without storing them.
