Why switch

Why teams move off Datadog

Self-hosting is not only about saving money. These are the reasons people make the switch.

  • Own your data

    Your data lives on a server you control, not on Datadog's infrastructure. No surprise policy changes and no lock-in.

  • No per-seat pricing

    Open-source alternatives to Datadog are free to run for as many users as your server can handle. A small VPS often costs less than a single subscription.

  • Customize and extend

    Read the code, add plugins, connect it to your own tools and automate it through open APIs. When you need a feature, you can build it or fund it.

What is the best open-source alternative to Datadog?

Grafana is the most popular open-source alternative to Datadog, with 77,096 GitHub stars. Prometheus and Zabbix are also strong choices. Compare features, license and recent activity to find the best fit for your team.

Is there a free alternative to Datadog?

Yes. All 7 apps on this page are open source and free to self-host, so you can run a Datadog replacement without per-user fees. You only pay for the server, and a small VPS is usually enough for personal use or a small team.

Can I self-host an alternative to Datadog?

Yes. Grafana, Prometheus and Zabbix ship a Docker image, so you can run them on a home server or VPS with Docker Compose in a few minutes. Your data then stays on hardware you control.

How do I migrate from Datadog?

Start by exporting your data from Datadog, then check the import options of the app you pick, since many projects ship importers for popular formats. Run both side by side for a week before you switch so nothing is lost.
