TuneBad vs Tunebat
Both tools tell you the key and BPM of a song. They get there in very different ways, and which one fits depends on what you are working with. Here is a straight comparison.
The short version
Tunebat is a search engine over a huge catalog of songs. You type a track and it shows the key, BPM, and other data it has on file. That is fast and accurate for popular releases.
TuneBad listens instead of looking up. You give it a file or a link and it analyzes the actual audio in your browser. That means it works on remixes, edits, DJ rips, and songs that were never added to any database, and it is completely free with no ads and no account.

Harmonic mixing and similar songs
Every TuneBad analysis includes the Camelot code, and every page in the song database shows which codes mix cleanly with it and links real compatible-key and same-key tracks to play next. The playlist analyzer takes a whole Spotify or YouTube playlist and sorts it into Camelot-wheel order for a DJ set, and the Camelot wheel guide explains the system if it is new to you.
When to use Tunebat
If you just want to look up a well-known, released track and you do not mind the ads, its database is deep and the answer is one search away. Its filtered search, where you dig for songs by key and BPM, is also genuinely useful for building sets.
When to use TuneBad
If the track is a remix, a bootleg, an unreleased demo, or your own production, a database will not have it, so you need something that reads the audio. TuneBad does that, keeps your file on your device, and never asks you to sign up or sit through ads. And once you are there, the same site handles loudness, slowed and reverb, pitch, delay times, and cutting an MP3.
Common questions
Is TuneBad a Tunebat alternative?
Yes. Both find the key and BPM of a song, and TuneBad is free with no ads or account. The main difference is how they work: TuneBad analyzes the audio you give it, while Tunebat looks songs up in a large database.
Which one is more accurate?
For a song in Tunebat's database, its stored values are a good reference. TuneBad measures the audio directly, which means it also works on remixes, edits, and unreleased tracks that no database has. For those, analyzing the file is the only option.
Can TuneBad find the key of a YouTube or Spotify link?
Yes. Paste a link and TuneBad pulls the official preview and analyzes it in your browser. If the song is not on a streaming service, upload the file instead.
Is TuneBad really free?
Yes. Every tool is free, there are no ads, and you never make an account. Audio analysis happens on your own device, so files are never uploaded.
Does TuneBad support harmonic mixing?
Yes. Every analysis returns the Camelot code, every song page lists which Camelot codes mix with it and links compatible-key and same-key tracks, the playlist analyzer sorts a whole set into Camelot-wheel order, and there is a guide explaining the wheel.
