Free to self-host. Cloud when you want it.
Monitoring is never behind a paywall. You'll pay only if you want us to run it for you, or need enterprise controls.

Questions
Is the Community edition really free?
Yes. It's open source under AGPL-3.0, with no limit on Kubernetes clusters, Docker fleets, nodes or users. Monitoring, the service map and alerting are never paywalled, and nothing that is free today will become paid.
What counts as a node?
A Kubernetes node or a Docker host running the WatchLog agent. Cloud will bill the 95th percentile of the month's hourly node counts, so a short spike doesn't cost extra.
What data leaves my cluster or my hosts?
When you self-host, nothing leaves your infrastructure: the agents send metrics, object summaries and events only to your own WatchLog server. Secrets, environment variables and payloads are never read, and the software sends nothing to us. An AI assistant sees data only if you give it a token.
Can I use AGPL software at work?
Yes. Running WatchLog, unmodified, for your own systems asks nothing of you. If you modify it and other people use your modified version over a network, the AGPL asks you to offer them its source.
Can I run it air-gapped?
Yes. Mirror the images (and, for Kubernetes, the charts) into your own registry; agents connect only to your WatchLog server. Email alerts work through your SMTP server. A documented air-gapped install with offline licences is planned for Enterprise.
When does Cloud launch?
After the self-hosted product settles. Join the waitlist and we'll email you once, when it opens.
How is it different from Coroot or Netdata?
Coroot is the closest: an eBPF service map plus tracing, logs, profiling and SLOs, free under Apache-2.0. Netdata collects far more metrics, every second, across hundreds of integrations. WatchLog is narrower on purpose: fixed Kubernetes and Docker views, a service map and alerts that work on day one, with a lighter node agent. If you need tracing or per-second metrics, they are the better choice.
Why not just Prometheus and Grafana?
It's a great stack if you have the time to build and own it: exporters, scrape configs, dashboards and alert rules, in PromQL, and a service map needs a service mesh or tracing. WatchLog installs in one command with opinionated views, default alert rules and a service map from eBPF, and needs no query language. If you want any metric on any dashboard, Prometheus and Grafana are more flexible.
