Best open-source alternatives to Datadog

A cloud observability platform for metrics, logs, and traces.

Datadog unifies infrastructure metrics, application traces, and log aggregation with dashboards and alerting in a SaaS model. Its per-host and per-GB pricing can become substantial at scale, and sending telemetry data to a third party is a non-starter for regulated industries.

    HyperDX is an observability application that helps engineers investigate production issues by searching and visualizing telemetry data stored in ClickHouse. It is presented as a core component of ClickStack and is positioned as a fast, intuitive alternative for working with logs and traces on top of an existing ClickHouse cluster. The project is aimed at teams that need a unified way to work with logs, metrics, session replays, traces, dashboards, alerts, and APM-style request and database monitoring. It can be deployed as an all-in-one container or as part of a broader ClickStack setup, and it supports OpenTelemetry-based instrumentation through its collector endpoint and SDK integrations for common languages and platforms.

What to look for in a Datadog alternative

Ensure the alternative covers all three observability pillars: metrics (Prometheus-compatible), logs (structured log ingestion), and distributed traces (OpenTelemetry support). Scalability of the storage backend matters for high-volume environments. Alert routing, on-call integrations, and dashboard templating are table-stakes features for production operations teams.
