Uptrace

Uptrace is an OpenTelemetry-native observability platform that unifies traces, metrics and logs. It provides UQL for querying spans and logs and a PromQL-compatible engine for metrics. Dashboards can combine spans, events, logs and metrics, configured in the UI or YAML. Metric and error monitors can send notifications through email, Slack, PagerDuty and other channels. Uptrace lists Grafana integration as a Prometheus and Tempo data source and includes a built-in MCP server for AI assistants. It offers cloud and self-hosted deployment, with Docker, Ansible and Kubernetes installation options; precompiled binaries are listed for Linux, macOS and Windows. Uptrace Cloud retains data for four weeks by default, with cold storage options for up to 100 weeks. The free Cloud plan includes 50 GB per month and 5,000 timeseries per month, while Community is free with unlimited usage and 14 days of retention. Paid plans start at $39 a month. The privacy policy says data in transit and database backups are encrypted, but most live database data is not encrypted at rest.
