EnergyCurve vs Lexicon
The least overlapping pair on this list. One is about thousands of files staying in order across six programs. The other is about sixty minutes being in the right order once.
What each one does
Lexicon calls itself "a robust music library management tool designed for DJs, by DJs", running "on Windows & macOS" and supporting "Rekordbox, Serato, Traktor, VirtualDJ, Engine DJ and djay Pro". Its pricing page is blunt about the split: "Downloading Lexicon and converting your library between any of the DJ apps we support is 100% free. Upgrade to a paid plan when you want the library management tools."
That is a different problem from ours, and a real one. If you have switched controllers twice and your cue points are scattered across three programs, no amount of set analysis helps you; a converter does.
EnergyCurve never looks at your library as a whole. It looks at one playlist, in the order you put it in, and asks what that hour does.

When each one is the right call
Lexicon is the right call if your problem is the library. Moving from Serato to Rekordbox without losing cue points, cleaning up duplicates, keeping two computers in agreement, backing the whole thing up. We do none of that, and if that is the pain, we are the wrong purchase.
Their conversion being free is worth knowing even if you never pay them: by their own description, converting a library to and from any supported app costs nothing.
EnergyCurve is the right call when the library is fine and the set is the question. It reads what your library exports and gives back an order — it does not want to own your collection, and it does not ask you to move it anywhere.
These two are the most complementary pair on this list. A library kept straight by one and a night shaped by the other do not compete for the same hour of your week.
Questions
Can EnergyCurve convert my library between Rekordbox and Serato?
No. It imports a playlist and exports a playlist, and that is the whole of its relationship with your files. Converting a library — cue points, beatgrids, folder structure — is a different job, and Lexicon describes doing it for free.
Do I have to choose between them?
No, and of the four comparisons on this site this is the one where using both makes the most obvious sense. Lexicon keeps the library coherent across the programs you use; EnergyCurve reads a playlist out of whichever of them you are playing from.
Does Lexicon analyse the energy of a set?
Not as something they advertise. Their pages describe library management, conversion, editing and analysis scans across a collection. We are describing what their own pages say, not what the software may do internally — if that matters to your decision, their feature list is the place to check.
