A disk-space map that checks the floorboards again before cutting them out.

What is it?

Excise is an interactive terminal disk-usage explorer and independent successor to Diskonaut. It draws a treemap of storage while distinguishing apparent size from allocated space and avoiding double-counting hard-linked file identities.

Why did Radar notice it?

Disk cleaners are exactly where cheerful convenience becomes dangerous. Excise's interesting idea is to treat deletion as a state-change problem rather than merely a confirmation dialog. Its documented deletion plan binds targets to filesystem identities, refuses to follow links and revalidates entries before mutation so a file changed after inspection is not silently swept away.

That is unusually serious thinking for a small terminal utility, and the same boundedness appears in scanner queues, memory, worker counts and report formats.

What looks good?

The project exposes deterministic table and versioned JSON output as well as the TUI, and explicitly distinguishes unknown measurements from exact ones. Accessibility details such as monochrome, ASCII and reduced-motion modes are also present rather than bolted on as an afterthought.

What's the catch?

The catch is printed in enormous conceptual letters: deletion is permanent and there is no trash or undo. The project itself calls current releases early-testing software and recommends disposable directories. Toolglass has not verified race handling, hard-link accounting, platform differences or recovery from interruption.

Who might want it?

Developers and administrators who like visual disk explorers but want the destructive part to behave more like a carefully checked transaction than a red button.
