Overview

CRATELAB brings crate organization, track analysis, playlist creation and cloud-library sync into one multi-platform product. The Free plan is oriented toward cloud-library browsing and playback; Pro adds the analysis capacity and unlimited library size that make the software more useful for building and maintaining a working collection.

Audio stays on the user's computer unless they choose to push it to the cloud, while metadata syncs by default. Browsing, editing and playback work offline, but local analysis requires an internet connection to verify the subscription. That split supports offline library work without making analysis fully independent of connectivity.

Key features

Track analysis: The desktop analyzer performs beat tracking locally and claims tempo detection to ±0.5 BPM. It also identifies keys in Camelot notation and scores energy from 1 to 10, useful cues for harmonic and intensity-based sorting.
Track structure: Automatic mapping of intros, builds and drops, displayed in section-coloured waveforms, gives DJs structural context when preparing tracks.
Mix planning: AI playlist generation, transition compatibility scoring and an AI DJ coach offer several ways to shape a set. These are preparation aids alongside crate organization, rather than a substitute for the user's own selection.
Library handoff: Metadata can be exported as CSV or sent through direct integrations with Rekordbox, Serato and Engine DJ via the Sync page. That makes CRATELAB more relevant to DJs who prepare in one place and perform with another platform.

Pricing

Plan	Price	What it includes
Free	0.00 USD per free	Sign-in required; browse a synced cloud library, stream playback and pull tracks from the cloud. Playback and cloud pull remain in the free tier.
Pro	9.99 USD per month	200 analysis credits refreshed monthly, unlimited library size and priority support; cancel anytime. An active internet connection is required for subscription verification.

Free is a reasonable fit for someone who mainly needs cloud-library access and playback, but it does not include a stated analysis allowance. Pro is the relevant choice for analysis and larger libraries, though its 200-credit cycle permits one analyzed track per credit. Unused credits do not roll over, and additional credits can be bought ad hoc, so frequent crate analysis may require more than the monthly subscription. Payments run through Stripe, and cancellation is available from the Billing page.

Platforms

CRATELAB supports Linux, macOS, Windows and the web. The desktop analyzer is the part described as performing local beat tracking; cloud-library access and sync provide the web-facing side of the product.

Who it's for

CRATELAB is best suited to DJs who want track-analysis cues, structural mapping and AI-assisted set planning connected to a cloud library and familiar export destinations. It is less suited to DJs who need to analyze a large collection in one go or work offline during analysis: Pro has a finite monthly credit pool, and verification requires an internet connection.

Pros and cons

Pro: Local beat tracking, Camelot key detection and energy scoring give DJs several useful sorting dimensions in one analyzer.
Pro: CSV export and direct links to Rekordbox, Serato and Engine DJ make prepared metadata easier to carry into established DJ software.
Pro: Audio remains local unless deliberately sent to the cloud, while offline browsing, editing and playback preserve core library access without connectivity.
Con: Pro's 200 analysis credits per cycle cap routine analysis; unused credits expire at the cycle boundary rather than accumulating.
Con: Local analysis still needs internet access for subscription verification, limiting its usefulness for disconnected preparation.
Con: The Free plan centers on cloud-library playback and pulling tracks, so it is not a free route to an ongoing local-analysis workflow.

Alternatives

CortexDJ is worth considering for home users who want analysis, AI auto-mix, mashups, live decks and mix rendering on up to two computers, with exports to Rekordbox and Serato in its free plan.
djay is a better fit for someone seeking a free-download option with core mixing features, or who needs Android and iOS alongside desktop platforms; advanced features require its optional PRO subscription.
Offtrack is another freemium choice for DJs who prefer an option spanning Android, iOS and macOS.
SetPrep offers a free plan capped at three mixes per month and a Pro Monthly plan at 5.99 GBP per month; it suits readers comparing a mix-limited free tier with a lower-priced monthly plan.
AuraJam is a web-only alternative whose free plan allows five exports a day with a small mark on exports, while on-device tools are unmetered.
automixer.ai has a free plan with three projects, six tracks per project, five exports per month, MP3 320kbps and 1 GB storage; it may suit someone whose needs fit those project and export caps.
Mixbridge is a free app for iOS and web.
MIXX Intelligence is a macOS alternative whose free Prepare plan includes importing and analyzing a crate, with key, BPM and energy information on tracks.

AI DJ Software provides a broader category view for readers still comparing options.

Verdict

Choose CRATELAB if you want local track analysis, playlist planning and cloud-library organization connected to Rekordbox, Serato or Engine DJ exports. Its strongest advantage is bringing those preparation tasks together while keeping audio local by default. Look elsewhere if your workflow depends on analyzing more than 200 tracks per Pro cycle without extra purchases, or on analyzing while offline.
