Know which PC tweaks actually help your rig.
Measured,
not promised.
Every optimizer promises speed. Compy proves what's true on your rig: it reads your actual hardware, grades the internet's favorite tweaks — real, placebo, or risky — and measures what actually changed. When a fix is real, you see the numbers. When it isn't, you see that too. Everything it changes, it can undo.
Reads your hardware
Verdicts are tailored to the PC in front of you — GPU, CPU, drives, display — never copied off a YouTube "best settings" list. If a tweak isn't for your rig, Compy says so.
Measures what changed
Frames, 1% lows, temps — before and after, on your own sessions. Real improvements get named loudly. No measurable change gets called exactly that.
Keeps the receipt
Every change is snapshotted first and undoable later — exact prior state, kept on your PC. Rollback isn't a feature here; it's the foundation.
It actually does something. A measurable or well-proven effect on your games — worth doing.
All hype, no effect. Popular online, but it changes nothing you can measure. We skip these so you don't waste time chasing them.
Not worth the downside. It might do something, but it brings real tradeoffs — instability, a security hole, or things breaking — so Compy refuses it, or lets you decide with eyes open.

Read the honest verdict →Get the launch email
Compy is invite-only today. The waitlist is your spot in line for public launch — you'll get exactly one email the day it opens. Nothing else.
Your email is stored only to send that one launch message — nothing else, no third parties, no tracking. The app itself sends nothing off your PC.

The public build will live right here. Until then Compy ships by invite only — the waitlist above is the door.
