Local-only duplicate cleaner

Find
duplicates.
Keep the copy
you actually
want.

Onley scans your local storage with byte-level precision. It finds duplicate groups, compares file hashes, and reclaims wasted space. The desktop app deletes only after you confirm, and normal scans stay on your machine.

Why Onley?

Small tool. Clear decisions.

Local by default

The index lives at ~/.onley/local.db. Your privacy is built in: no telemetry, no cloud, and no account required.

Resume scans

Cancel at any time. Finished files stay indexed, and the next scan skips unchanged files. A bounded worker pool keeps CPU use predictable.

Newest or oldest

Keep the newest or oldest copy in every group by modification time. Equal times fall back to path order.

A closer look

Set the rule. Check the folders.

Onley settings with Keep oldest selected and the language choices
Settings: keep the newest, the oldest or the first path. The choice applies while a scan runs and again when it ends.
Onley filters showing the Downloads folder, file types and their counts
Filters: choose source folders and file types before a scan.

Built for power users
with a command-line interface.

CLI First

Scan, review, and clean from the terminal. The workflow is scriptable and fast.

Byte-level comparison

Onley compares file contents by hash, not just names, so renamed copies still match.

Low resource overhead

Written in Rust, with a bounded worker pool and a local SQLite index.
