About SketchLog

SketchLog is an innovative open-source observability platform designed for efficient telemetry analysis in production environments. It leverages advanced sketch data structures to generate compact summaries of telemetry data, enabling teams to quickly answer critical questions such as latency percentiles, unique user counts, top events, anomaly tracking, and SLO progress without the need to store every raw event indefinitely. This makes it especially appealing for organizations seeking scalable, cost-effective monitoring solutions. Its versatility is enhanced by features like a hosted playground, customizable dashboards, PostgreSQL durability, optional embedded storage via OmniKV, and a comprehensive set of SDKs, WebAssembly support, Docker images, and Kubernetes deployment guides. By focusing on proof-first CI/release checks, SketchLog ensures reliability and ease of integration for developers, making it suitable for both large-scale production environments and smaller teams interested in advanced telemetry analytics.
