Sentry Performance vs SigNoz

Sentry Performance is an application performance monitoring service for developers diagnosing bottlenecks in applications and distributed systems. It links performance problems with related errors, transactions, and code details to help teams assess user impact and investigate issues. Trace views and code context can help locate slow database queries, API calls, and associated code lines. Distributed tracing follows requests across services to help identify where latency or errors arise. Teams can prioritize performance issues by user impact and create custom metrics and alerts. Sentry lists integrations with GitHub, Jira, Slack, GitLab, Linear, Microsoft Teams, PagerDuty, Datadog, and Vercel, and supports OpenTelemetry. Its cloud service is hosted on Google Cloud Platform with a multi-tenant architecture; a self-hosted option is available for teams that need data in their own infrastructure. Trace retention is 90 days. The Developer plan costs nothing and has monthly usage quotas. Paid plans start at $26/mo; a free trial is available for Business, but not Team. Sentry makes its SOC 2 Type 2 report and ISO 27001 certificate available through user accounts or by request.

SigNoz is an open-source observability tool for monitoring applications and infrastructure. It brings logs, metrics, traces, and exceptions together with alerting and separate explorers for Trace, Logs, and Metrics. The OpenTelemetry-native design does not require proprietary agents. A Query Builder supports aggregations, filters, and formulas across signal types, while alerts can detect thresholds, anomalies, and Apdex conditions. Users can create dashboards from metrics, logs, and traces. APM charts cover p99 latency, error rate, Apdex, and operations per second, alongside database and external-call monitoring. Distributed tracing uses flamegraph and Gantt-chart views to follow requests across services. SigNoz stores telemetry in ClickHouse with hot and cold tiers. It can run in the cloud or be self-hosted using Docker, Docker Swarm, or Kubernetes. Cloud provides 30-day access to all features for new users; the self-hosted Community option is free but requires users to manage infrastructure, storage, scaling, upgrades, and backups.
