Free up disk space without the guesswork.
Tessera is a forensic disk inspector for macOS. It walks your home directory like a museum curator catalogues a collection — every byte placed, every category named, every reclaim traceable. Runs entirely on-device.
A cleaner that earns your trust.
Five surfaces, one mental model. Quick Scan from the menu bar; Atlas for the wide view; Free Up for the one-click reclaim; Minibar for ambient awareness; vectors for the long tail.
Quick Scan
Top-3 reclaimable in ~90 ms for 50k files, straight from the menu bar. No wait, no modal, no drama.
Atlas
A 10-tile treemap that finally shows what's eating your disk. Drill down by category, vector, or path.
Free Up
One-click reclaim of your top-3 space hogs. Every reclaim writes a manifest to Trash with a 30-day undo.
Minibar
Menubar popover with live counters, Snooze AI, Local-Only toggle, and the Drop Zone for ad-hoc folder scans.
14 cleanup vectors
Docker, Xcode DerivedData, iOS Sim runtimes, npm globals, browser caches, MAS, Mail, photos, music, Node, sandbox/temp — each with a domain-specific safety guard.
Privacy-first
Zero network calls during a scan. The walker is an embedded Rust engine. BYOK AI keys stay in Keychain. Local-Only hard toggle.
"Tessera shows the iOS Simulator empire as a single tile.
No other cleaner aggregates it."

Atlas treemap
10-tile vivid palette aggregates the byte-spend by category. Drilldown by vector, path, or last-touched date.

One-click Free Up
Top-3 reclaimable surfaced with per-vector safety guards: pgrep for Xcode, simctl for booted sims.

30-day manifest
