$39.99. Once.
No subscription, no account, no monthly anything. Try everything free for 48 hours first. And because a price should survive being explained, the full math is below.
Everything included. Every improvement so far has shipped to every install at no extra charge.
- Paste a playlist link or screenshot, get the tracklist read for you
- Missing tracks hunted down and pulled over your own connection
- Key, BPM and energy read from the audio itself, on your machine
- Uncertain keys flagged for a pre-listen, with a second candidate
- Crate sorted so neighbouring tracks mix in key
- A Rekordbox-ready playlist; Serato and Traktor read the same tags
The honest math
Prep night is five jobs: finding the tracks, downloading them, tagging, sorting, exporting. Mixed In Key, the key detector working DJs already pay for, lists at $58 and covers one of those jobs, genuinely well, on files you already have. Cratefox covers all five, and right now it costs less than that one step does.
Mixed In Key's list price is $58 at mixedinkey.com (checked July 2026; they run sales, and at any sale price it still covers the one step). No disrespect meant, it is the respected standard for that step.
The accuracy behind the price is published
A prep tool is only worth money if the tags it writes can be trusted, so we measure ours in public, against GiantSteps, an independent dataset of 1225 real Beatport tracks. On the 604 tracks that carry independent key labels, keys read 64.9% Camelot-exact and 77.8% safe to mix, weak spots are listed by genre, and any install can re-run the whole benchmark with the commands on the page. The uncertain keys get flagged in the app so you pre-listen those instead of trusting every tag. The full numbers, misses included →
Try it, then decide
48 hours, free
The full app, your real library, no card. A real person (the DJ who builds Cratefox) sends your trial code by email, usually within a day. Your 48 hours start when you install, not when the code arrives, so save the install for prep night. Everything you download during the trial stays yours, either way.
Prefer email? Write hey@cratefox.app and ask for a trial.
Buy it once: $39.99
Buying is personal for now, a person instead of a checkout page: leave your email and the maker replies with payment details, usually within a day. Pay, and your permanent code comes straight back. One payment, and you're done.
Prefer email? Write hey@cratefox.app and say you want in.
Fair questions
What happens when my 48 hours end?
Every track you downloaded is an ordinary file in your music folder and stays fully yours: playable in Rekordbox, Serato, or anything else, forever. The trial is a straight deal: 48 hours with the full app, then you either buy your permanent code or stop using it.
I already tag with something else. Will Cratefox fight my tags?
No. Cratefox reads your existing library in place and never overwrites a key or BPM you already have; it fills in what is missing and tags the tracks it downloads for you. Any key it writes can be auditioned and overridden before export.
Where do the downloads actually come from?
Over Soulseek, a peer-to-peer network, on your own connection and under your own name. In keeping with how Soulseek works, your downloads folder is shared back to the network by default, and the app has a switch to turn that off. You're responsible for what you pull and share. The plain-words explanation →
Is there really no subscription?
Really. $39.99 is the whole price. There is no plan to move to monthly, and if a future feature ever costs extra, it will be a separate, clearly labeled choice, announced on this page first.
Do updates cost extra?
They never have: every improvement so far has shipped to every install at no extra charge, and updating is just re-running your one-line install command.
Why isn't it free?
Because free tools are paid for somehow: ads, your data, or the maker burning out. Cratefox has no ads, no account, and your library never touches our servers, so the only honest way to keep it alive is to charge for it, once.
I installed through an invite already. What changes for me?
Nothing. Your code keeps working on your machine, and a new computer gets you a fresh code for the asking. The price applies to new installs from here on.
