Bytesweep

Bytesweep is a privacy-first disk space analyzer and cleaner for macOS, Linux, and soon Windows, positioned as a safer alternative to aggressive Mac cleaners. It targets developers, creatives, power users, and anyone whose Mac shows a mysterious 'System Data' bar or who runs local AI models, Xcode, Docker, simulators, package managers, and large media libraries. Core features include fast local scanning of drives and folders, eight interactive visualizations (Treemap, Folders, Sunburst, Flame, Bubbles, Mind Map, Top Sizes, Age Map), per-file inspector, duplicate and similar-photo detection, app uninstaller, cloud-file awareness, snapshots, live system monitor, weekly reports, and cross-machine summaries. Its standout safety model sorts items into Refused, Irreplaceable, Yours, and Rebuilt automatically; warns before deleting keys, git history, VMs, photo libraries, or open databases; and makes every sweep undoable for 7 days via restore points. Content is candid, explaining what the tool does not do: no speed boost, no automatic cleaning, no antivirus, no phoning home. User experience emphasizes no account, offline operation, keyboard accessibility, visible focus, and non-destructive cleanup. Technical features include on-device scanning, no telemetry, a single licence check, Developer ID signing and Apple notarization, least-privilege admin prompts, and one-time licence for three computers. Pricing is a one-time $5 purchase after a 14-day trial, with no subscription.
