Polar Signals Cloud
What Polar Signals Cloud is
Polar Signals Cloud is a hosted service for storing and analyzing continuous profiling data. Its agent collects profiles from a node without instrumentation and sends them to the cloud. The agent supports Kubernetes, Docker, ECS and bare-metal environments. Pro includes CPU, memory and GPU profiling for any language; listed language support includes C/C++, Rust, Go, Ruby, Python, PHP, Java-family languages, Graal Native, Node.js and .NET. Flame graphs, function-level filters and Prometheus-style selectors with custom dimensions help explore profiles. An MCP integration lets AI tools query profiling data for bottlenecks and optimization opportunities, while an extension displays inline metrics in VS Code and compatible editors including Cursor, Windsurf and Antigravity. The 14-day trial includes Pro features with rate limits and 14-day retention. Pro costs $50 a month, billed at $50 per 100 million samples per month, and includes 30-day retention. Enterprise pricing is custom; BYOC is available on request and requires contacting sales.
Who it suits
Polar Signals Cloud may suit engineering teams that want to analyze continuous profiles across supported languages and deployment environments. Its editor extension and MCP integration may also help teams working with compatible editors or AI tools.
