Polar Signals Cloud
A managed continuous profiling platform built by the creators of Parca, focused on eBPF-based whole-system profiling.
Last updated
Polar Signals Cloud is a managed continuous profiling platform originally built by the creators of the open-source Parca project. It uses eBPF to profile entire hosts and Kubernetes clusters without requiring per-language agents or code changes, and adds long-term storage, a hosted UI, and team collaboration features on top of what self-hosted Parca provides.
Polar Signals, the company, was acquired by Dash0 in August 2026. Polar Signals Cloud continues to operate as a product under Dash0, while Parca itself remains independently open source and maintained.
It’s aimed at teams that want Parca’s eBPF-based, whole-system profiling approach without operating the storage and query backend themselves. See Parca for the underlying open-source project.
