Your Mac,
cleared every Sunday.

Mulch lives in your menu bar and clears the build output, caches and leftovers your dev tools pile up, once a week, while your Mac is idle.

Three steps.
Then nothing.

  1. 1

    Install

    One command per Mac. It lands in your menu bar as a small leaf.

  2. 2

    First scan

    It finds your code folders and tools, and shows what the first sweep will clear before anything goes.

  3. 3

    Forget it

    Every Sunday, when your Mac is idle and on power, it sweeps. One quiet notification, only if something needs you.

How to use it

  1. 01 The number

    What Mulch can free right now.

  2. 02 Clean

    Clears every Auto rule in one go, if you do not want to wait for Sunday.

  3. 03 Needs you

    Riskier finds wait here. Clean or Skip.

  4. 04 The schedule

    When the next sweep runs, and what the last ones freed.

  5. 05 Open Mulch

    Every rule, every path, and why each one is safe to remove.
