Names what is slowing your Mac
One bar of your memory, each cause a row, and one button: Free or Quit.
Find what slows your Mac.
For developers running AI coding agents. Blame sits in the menu bar, names what is eating your memory, and ends only what is safe.
Free to download. macOS 14 or later, notarized by Apple.
On one 16 GB Mac, 11.4 GB sat in the background.
3.4 GBClaude Code’s MCP servers, across 3 sessions. Blame ends these.
8 GBDocker’s VM. Blame names it; quitting it is your call.
4.6 GBleft for everything else on the Mac
Blame finds what these leave running
- Claude Code
- Cursor
- OpenAI Codex
- Docker
- Playwright
- Chrome DevTools MCP
Every slowdown, named.
What holds your memory, why, and whether it is safe to end.
Shows what every AI session holds
Each Claude Code, Cursor, Codex, Gemini CLI or Aider session, its project, how long it has run, and End session.
Clears what tools leave on disk
Caches, old Playwright browsers and stale build folders, moved to the Trash.
Shows what changed
Memory spilled to disk, hour by hour, with every fix marked.
Autopilot fixes what can be undone
Slowing busy background work, restarting a leaking editor’s extensions and moving old temp files to the Trash act from day one. Each rule turns itself off if it is wrong on your Mac. Pausing apps turns on only after a week under 5% wrong. Ending old leftovers is a separate switch, off until you turn it on.
Answers from the menu bar
Its dot is green when stable, yellow when something needs attention, red when critical.
It ends only what is safe to end.
You see what will end and what stays. Cancel is the default.

Questions
Didn’t find your answer? Write to the founder.
Will it end something I need?
Only what passes the safety check ends. Databases are never ended from a button, a child doing protected work protects its whole tree, and every fix shows its list before you confirm.
Does Autopilot act on its own?
With Blame Pro, yes, for what can be undone: it slows busy background work, restarts a leaking editor’s extensions and moves old temp files to the Trash. Each rule turns itself off if it is wrong on your Mac, and you can switch any of them off. Free, it only suggests, and you choose Do it or Not this.
Activity Monitor is free. Why this?
Activity Monitor lists every process and its memory. It does not say which session left a program running, whether it is safe to end, or what slows your Mac right now. Blame names the cause and ends the whole tree after checking it is still the same program.
Stray and Node Killer are free. Why pay?
They find orphaned processes, and so does Blame. They do not diagnose a slow Mac, show what each AI session holds, or learn with Autopilot. Diagnosis and fixes are free; you pay only for Autopilot acting on its own.
Why not just restart?
A restart clears memory once and closes everything you had open. The leftovers come back with your next agent session. Blame ends only those, and keeps your work running.
What does it cost?
Diagnosis, one-click fixes, sessions, history and Autopilot suggestions are free. Autopilot acting on its own is Blame Pro: $29 once, for all your Macs, with every update to 1.x. There is no subscription.
Does anything leave my Mac?
Nothing about your processes. Blame checks getblame.app for updates once a day; switch that off in Settings › About. Anonymous usage counts are sent only if you switch them on: one report a day of counts, never a program name, a path or a command. Logs stay on your Mac for 14 days and Blame never sends them. Privacy has the details.
How heavy is it?
About 50 MB of memory and 1% CPU: a median of 48 MB on the 0.3.10 release build over 5 hours on 6 Oct 2026, up to 140 MB while its window is open.
Which Macs does it run on?
macOS 14 or later. It is a universal build, so it runs on Apple silicon and Intel Macs.
Why not the Mac App Store?
Its sandbox forbids signalling other processes, so Blame could not end anything. It is a direct download, signed with a Developer ID and notarized by Apple.
Next time your Mac slows down, you’ll know why.
Blame stays in the menu bar. One click shows what is holding your memory and ends only what is safe.
