What we've helped DJs achieve
Since launch, CrateGuard users have reclaimed over 2TB of wasted storage, identified 50,000+ duplicate tracks, and prevented countless mid-set disasters. We exist because no other tool understood DJ workflows.

Why we built this
Our own libraries were a mess. Duplicates under different names, mystery 128kbps files, corrupted tracks. Every tool we tried either didn't understand DJ workflows or required cloud uploads. So we built what we needed - and it turns out every DJ has the same problem.
How we work
Offline first
Your music never leaves your machine.
DJ workflows matter
We never touch cue points, beat grids, or hot cues.
Pay once, own it
No subscriptions. Lifetime updates included.
Ship what matters
One real problem solved well beats ten half-baked features.
