Best Free APM Traces Tools

Free tier includes access to all Grafana Cloud services with limited usage, 14-day retention, and community support. 10k metric series, 50 GB logs, and 50 GB traces are included. Pro costs $19 a month plus usage, includes 10k active series and 50 GB each of logs and traces, and bills usage above them. Pro keeps metrics for 13 months and logs, traces, profiles and k6 tests for 30 days.

• Free and Trial accounts opened on or after 2026-04-20 can only send email alerts and reports to users in their own Grafana instance. Other email recipients are rejected. Cloud Alertmanager is unavailable; native Grafana Alertmanager is used. Webhooks and other alert integrations are unaffected. Upgrading lifts the email limit. Older free accounts are unaffected.

• Free-tier stacks have a hard cap of 1,000 dashboards and 1,000 folders. Stacks already above the cap keep their existing resources. (From grafana.com/whats-new/2026-04-07-introducing-limits-to-dashboards-and-folders-resources, read 2026-11-02.)
