About Middleware

Middleware is a full-stack observability platform for infrastructure, APM, logs, metrics, traces, RUM, synthetics, browser testing, LLM observability, dashboards, alerts, and AI SRE workflows. Its public pages emphasize OpenTelemetry-friendly telemetry and incident correlation across front-end, back-end, cloud, Kubernetes, endpoint, and model-application signals.

The current pricing page is more specific than a generic freemium label: a 14-day Free Trial at $0 includes unlimited data ingestion, unlimited RUM sessions, unlimited synthetic checks, 10 browser test runs, unlimited users, community support, and 14-day retention. Middleware also presents Pay As You Go and Enterprise paths for teams that need production scale, security, support, or custom commercial terms.

Middleware is most useful for teams that want a broad observability suite and are willing to validate AI-SRE claims on their own incidents. Before replacing an incumbent, test integrations, telemetry volume, retention, alert noise, query ergonomics, privacy controls, LLM observability coverage, and whether OpsAI correlation or remediation actually shortens diagnosis on production-like services.
