Here is the short version. LANDR masters. Bandmixr mixes and masters. If you are not sure which of those you need, that is exactly the question this post answers.
Mixing and mastering are not the same job
The whole comparison rests on this, so a quick recap.
Mixing takes your separate instrument tracks, the stems, and balances them into one cohesive stereo file: levels, EQ, compression, panning, reverb. Mastering takes a song that is already mixed and polishes it for release: loudness, tonal balance, format.
Mastering cannot fix a mix. If your kick and bass are masking each other, a master just makes that problem louder. So the first question is always simple. Do you already have a finished mix, or separate stems that still need balancing?
What LANDR does
LANDR launched in 2014 and is the most established name in automated mastering. You give it a finished stereo mix, it returns a master. Around that it has built a full ecosystem: distribution to streaming platforms, a large sample library, a plugin marketplace, collaboration tools, and courses.
Strengths. It is mature and widely trusted. It offers style and intensity options, a plugin for auditioning masters inside your DAW, and the convenience of mastering plus distribution under one login.
Limits. LANDR masters, it does not mix from stems. If your individual tracks still need balancing, LANDR cannot do that for you. The free tier is preview only, so downloads need a paid plan, and the cheaper plans cap how many WAV exports or formats you get.
Pricing. Subscription tiers, roughly $8 to $25 per month depending on plan and billing period, with the higher tiers bundling distribution, samples, and the plugin. Free accounts can preview but not download.
What Bandmixr does
Bandmixr starts a step earlier. You upload your individual stems, pick a genre, and the engine analyzes every track for loudness, frequency content, dynamics, phase, clipping, tempo, and key. It then mixes them with genre-aware EQ, compression, panning, reverb, and clash resolution, and masters the result, all in the browser.
Strengths. It actually mixes, not just masters. Genre profiles mean a jazz trio and a metal band are not run through the same template. After the first pass you get a preview screen to adjust per-stem faders, panning, reverb, and mutes, then regenerate instantly. Mastering is built in with three presets (Streaming, Standard, Loud) plus reference matching on paid plans. Exports are 44.1kHz/24-bit WAV, FLAC, or MP3. There is a free Rehearsal Cutter available, which splits long jam recordings into individual songs on your device. And Bandmixr never trains AI on your audio.
Limits. It is a newer service. The full analyze, mix, and export pass takes a few minutes rather than seconds. There is no built-in distribution, so getting onto Spotify is a separate step. And like any automated tool, it will not replace a top human engineer on a flagship release.
Pricing. A free plan includes one free download, then pay-per-download credits. Creator is $14/mo, or $10/mo billed yearly, with unlimited downloads and reference matching. Pro is $19/mo, or $15/mo yearly, and adds the Rehearsal Cutter and processed stem exports.

Which one should you choose?
You have separate stems and no finished mix. This is Bandmixr. LANDR has nothing to mix, because it needs a stereo file. Bandmixr takes raw stems to a finished master in one workflow.
You already have a finished, well-balanced mix and only need a master. LANDR is a strong, proven choice, especially if you also want distribution in the same place.
You record full rehearsals or jam sessions. Bandmixr. The Rehearsal Cutter splits a long recording into individual songs before you mix.
Have stems sitting on a hard drive? The fastest way to hear what they could sound like is to upload them. The first mix is free at bandmixr.com.
