Kudu is a system maintenance suite with a free, open-source desktop app for Windows, macOS, and Linux, alongside cloud tools for managing device fleets. Its desktop app handles junk cleanup, performance monitoring, security and privacy tools, software updates, and scheduled maintenance. Cleanup Receipts record which items were selected, removed, skipped, or failed; Storage History tracks folder growth and compares snapshots. Recovery Centre lets users inspect supported recovery records and restore eligible settings. Desktop maintenance runs locally, and the app does not collect, transmit, or store personal data by default.

Kudu Cloud adds a browser dashboard for device health, telemetry, remote commands, and maintenance automation. It checks SOC 2, CIS, and NIST controls and provides hardening assessments and audit-ready reports. Connected-device telemetry excludes file paths, contents, browsing history, passwords, and personally identifiable information; process-name sharing is opt-in. The desktop app is free. Cloud Basic costs $5/device/mo and Pro costs $9/device/mo, each starting at one device.
