Metoro Kubernetes Profiling vs Sentry Continuous Profiling

Metoro Kubernetes Profiling continuously profiles Kubernetes workloads with an eBPF sampler running at the kernel level. It creates interactive flame graphs that can be grouped by service, pod, or container and filtered by cluster, namespace, deployment, or Kubernetes label. Metoro lists Go, Python, C++, C, Rust, Node.js, and Java support, with host-level frames for other runtimes. Profiling does not require SDKs, code changes, language agents, restarts, or rebuilds, and can cover third-party containers and vendor workloads. Profiles connect to Metoro APM traces, logs, metrics, pod state, and deployment context. Installation uses Helm, with Cloud, BYOC, and on-premises deployment options. The free Hobby plan includes one cluster, one user, and two nodes with 28-day retention. Scale costs $20 USD per node per month, plus $0.20 per GB above 100GB per node. Enterprise pricing is contract-based and offers custom retention and SLAs. eBPF requires Linux kernel 4.18 or newer.

Sentry Continuous Profiling helps teams locate backend performance bottlenecks in Node.js and Python code, down to functions and lines. Continuous profiles can run for unlimited durations. An Aggregate Flamegraph summarizes project performance without requiring a single transaction as its scope. Developers can control profiling manually with SDK APIs or configure it to follow a trace lifecycle, starting when a root span is active. UI Profiling covers iOS, macOS and Android, with browser JavaScript and Electron also listed. Sentry says profiling requires performance monitoring to be enabled in the app, and availability for continuous profiling depends on the SDK. Continuous and UI Profiling use separate profile-hour billing measures and are available through pay-as-you-go usage. Sentry lists a free plan and paid pricing from $26/mo. Its integrations include GitHub, Jira, Slack, GitLab, Linear, Microsoft Teams and PagerDuty. Sentry says its service is hosted on Google Cloud Platform and has SOC 2 Type 2 and ISO 27001 certification and a HIPAA attestation.
