Continuous profiling data for finding CPU and memory hotspots.

Continuous profiling data for finding CPU and memory hotspots.
Polar Signals runs continuous profiling, showing line by line how code uses CPU and memory in production. Connected to a workspace, GBrain can answer “which functions used the most CPU in the API service over the last hour?” and point at where to optimize.
Signing in happens with a Polar Signals account, and the connection only reads.
GBrain gives Polar Signals a command line too. From a terminal, a
script or Claude Code,
gbrainio tool help polar-signals
lists its commands once it is connected.
