Caretta vs groundcover

Caretta is a free, self-hosted Kubernetes tool from groundcover that creates a visual map of services and their network interactions. It uses eBPF for collection and is designed for Linux systems with kernel 4.16 or later and CO-RE support. The project describes a minimal footprint and says no cluster modifications are required. Installation is documented through a Helm chart, with a recommendation to use a new, unique namespace. The chart includes Grafana with a predefined Caretta dashboard and VictoriaMetrics for collecting and publishing metrics that Prometheus-compatible dashboards can consume. Both bundled services are enabled by default, as is a five-second metrics polling interval, while Helm values can disable either component. Persistent storage for VictoriaMetrics starts disabled but can be enabled. Grafana’s default setup enables anonymous mode and includes administrator credentials in the README. Caretta is self-hosted, Apache-2.0 licensed, and support is directed through Slack or repository issues.

groundcover is a cloud-native observability platform for monitoring production environments. Its eBPF sensor collects metrics, logs, and traces without code changes or manual instrumentation, processes data at the edge, and the product states that ingestion happens in real time without sampling. Bring Your Own Cloud deployment puts the backend in the customer’s cloud while groundcover manages it and hosts the UI. Fully On-Prem deployment places both backend and UI on customer premises, including cloud or physical servers. Integrations include Kubernetes, OpenTelemetry, Prometheus, AWS CloudWatch, Google Cloud Monitoring, Azure, MongoDB Atlas, Redis Cloud, Datadog, and GitHub. Agent Mode can investigate telemetry and create dashboards, monitors, gcQL queries, and OTTL pipelines. The Free plan is free forever and includes 12-hour data retention and Slack Community support; paid plans start at $30 per host per month. Billing is based on average monthly monitored Kubernetes nodes or Linux hosts, not telemetry volume. The platform is available on Linux, self-hosted, and web.
