What Polar Signals Cloud is

Polar Signals Cloud is a hosted service for collecting, storing, and analyzing continuous profiling data. An agent runs on a node and sends profiling data without requiring application instrumentation. It supports sampling profiles for CPU, memory, and threads, while the Pro tier adds GPU profiling for any language. Documentation lists C, C++, Rust, Go, Python, Ruby, Java, Node.js, C#, Erlang, and Julia support, with additional Java-family and runtime languages listed by the product. Profiles can be explored through flame graphs, function-level filters, and Prometheus-style selectors with custom dimensions. GPU views include per-kernel timing, CPU stack traces, and CUDA Graph support. An MCP integration allows AI tools to query profiles for bottlenecks and optimization opportunities. A Profiler extension places metrics inline in VS Code and compatible editors. Agents support Kubernetes, Docker, ECS, and bare-metal environments. The cloud deployment has a 14-day trial; Pro costs $50 a month.
