Grafana Cloud vs PostHog
Compare Grafana Cloud and PostHog side by side. Features, pricing, pros and cons to help you choose between infrastructure observability and product analytics.
🏆 Quick Verdict
Grafana Cloud is the go-to for infrastructure observability — metrics, logs, and traces built on the open-source Prometheus/Loki/Tempo stack. PostHog is the go-to for product analytics — understanding how users behave, with feature flags and A/B testing included. They serve different teams and different questions, making them complementary rather than competitive.

In-Depth Analysis
Grafana Cloud is the managed cloud offering built on top of Grafana's open-source ecosystem — Prometheus for metrics, Loki for logs, and Tempo for distributed traces. If you're already running Prometheus or have Kubernetes clusters, Grafana Cloud is the natural place to ship that telemetry. The dashboard editor is class-leading, and the alerting system (now powered by Grafana Alerting, formerly Prometheus Alertmanager) handles complex multi-condition rules well. The free tier includes 10,000 active metrics, 50GB of logs, and 50GB of traces per month.
PostHog takes the opposite approach: instead of infrastructure observability, it focuses on product behavior. Event tracking, funnel analysis, session recordings, heat maps, cohorts, feature flags, and A/B tests are all built into a single platform. PostHog is open source (MIT licensed) and can be self-hosted on your own Kubernetes cluster, which appeals to the same DevOps-savvy teams who might also be running Grafana. The free cloud tier covers 1 million events and 5,000 session recordings per month.
Where Grafana Cloud answers 'is our infrastructure healthy?' and 'why is p99 latency spiking?', PostHog answers 'where do users drop off in the onboarding flow?' and 'does feature flag variant B increase activation?'. The technical profiles of users overlap — both attract engineers who prefer self-hostable, open-source tools — but the job-to-be-done is different. Notably, Grafana Cloud doesn't do error tracking or product analytics, and PostHog doesn't do metrics collection or log aggregation.
Teams at scale often run both. A common stack: Grafana Cloud for infrastructure metrics (Kubernetes nodes, database query times, API latency), PostHog for product analytics (user journeys, feature rollouts, conversion experiments). Both have strong free tiers that make adoption low-risk. If you're forced to choose one based on budget, start with PostHog if you're building a B2C or PLG product where user behavior data drives decisions, and start with Grafana if you're running complex distributed infrastructure where operational reliability is the priority.
Who Should Choose What?
Choose Grafana Cloud if:
Ops-savvy teams who want open-source metrics, logs, and traces on the Prometheus/Loki stack with best-in-class dashboards
Choose PostHog if:
Product and engineering teams who want open-source user analytics, feature flags, and A/B testing without stitching together multiple SaaS tools
