Which AI music generators are actually free, and where does free stop?

Nine tabs open, the word "free" on every button, and the same sentence sitting two clicks deeper in all nine: free generations are for personal, non commercial use. That sentence is where free stops. It is almost never on the page you landed on.

Short answer first, because that is what you came for. Suno, Udio, Riffusion, MusicGPT, Boomy, Soundful, Beatoven, Loudly and Stable Audio all run a free tier of some shape. Most of them will let you hear something in your browser today without a card, though what comes back differs sharply: some sing a full song, others hand you an instrumental bed or a preview you cannot download. Which makes "which AI music generator is free" a question with nine yes answers and almost no information inside it.

The question that pays for your evening is the next one: what does the free version take back? Four things, and it is the same four every time.

The four questions, and only these four matter

1. Runway. How many tracks before the wall, and whether the wall lifts tomorrow morning or at the start of next month. A daily refill and a monthly bucket feel identical on day one and completely different on day three, when you are on your eleventh attempt at a chorus that still lands flat.

2. Commercial use. Whether the thing you just made is allowed to earn money. This is the most common restriction in the whole category and the one people find last, usually after the video is edited.

3. The file. Whether you can get actual audio off the site, in what format, and with what stamped into it. Sometimes the free tier streams and will not download. Sometimes it downloads and the licence still says no.

4. What survives an upgrade. Whether paying next month retroactively cleans the track you made this month, or whether that track stays on free tier terms for the rest of its life. This one is brutal and almost nobody checks it before they need to.

Miss question two and you build a launch video around a song you are not allowed to monetise. Miss question four and you pay anyway, and the song you actually wanted is still not clean, so you generate it again and hope lightning strikes twice.

You will notice there is no comparison table below. A grid of credit counts and price points here would be a lie with borders around it: those cells change every few weeks, and a wrong number about somebody else's product is worse than no number at all. What does not change is the shape of the trap, so that is what this page maps.

The one piece of this with no free tier trap on it

Every tool on that list asks you for two things it cannot invent well on your behalf: a style description and a lyric. Feed either one vaguely and the model averages you into the middle of its training data. That is how people burn a whole free allowance in an afternoon and conclude the tool is bad, when the brief was bad.

So here is our side of it, stated plainly and early rather than at the bottom where you would never reach it. sunomarket does not make music. No audio, ever, not now and not on a paid plan. What the lyrics generator does is take a filled form and return a title plus a complete lyric, already carrying [Verse] and [Chorus] section tags so it drops straight into whichever of these tools actually takes a lyric. One generation costs 20 credits, and at 100 credits to the dollar that is twenty cents.

Twenty cents is not the offer. It is the proof. Nobody reaches for a card over twenty cents, and it is not meant to be reached for: it is there so you can see what the words cost before you commit to anything. The actual ask is nineteen dollars once, for good, or five a month if you would rather rent. After that the words stop being a line item you think about.

The reason this matters in an article about free tiers is the part nobody puts on a pricing page: there is no non commercial free tier here to graduate out of. What you generate on the cheapest possible path is yours to release, sell and monetise from the first line, we claim no rights in it and ask for no credit. Two of those limits matter here, and the rest sit on our disclaimer page, including the separate question of what the law where you live will treat as protectable. The text is non exclusive, so what a model writes for you can resemble what it writes for somebody else, and we clear nothing against anyone else's rights, meaning anything you intend to release you check yourself. That is a smaller catch than "personal use only", but it is a catch and you should know it now rather than in a comment thread.

We are also not Suno, not affiliated with Suno, and not speaking for Suno. We make the words. The singing happens somewhere else, under somebody else's terms.

Where free stops, tool by tool

Read every one of these as "at the time of writing, and go look". Free tiers in this category get rewritten roughly as often as the models do.

Suno is the one most people mean when they say AI music generator, and its free plan is a real free plan: a credit allowance that refills, full songs with a lead vocal, no card. The leash is commercial use. Suno's own terms have long described free-tier output as personal and non-commercial, which is exactly the wall this article is about, and it is a licence wall rather than an audible one: nothing in the audio stops you, the terms do. Read the current version before anything you made there earns money. We wrote the long version of that in is Suno AI free, including what paying actually changes.

Udio sits closest to Suno on what it does and is generally the better of the two on raw audio texture, worse on finishing a full arrangement without nudging. Same structural story on free: generate for nothing, and the permission to put the result behind a paywall or an ad is the thing the paid tier sells. If you are choosing between those two specifically, we compared them properly in Suno vs Udio instead of repeating it here.

Riffusion has run one of the more open free tiers among the tools that actually sing, which is why it keeps showing up in "actually free" lists. Treat that as a business decision rather than a law of nature. Generosity in this category has a habit of being a launch phase.

MusicGPT is a freemium credit model with the usual gravity: free credits, then the interesting features start living behind the plan. Read what the free credits are allowed to produce, not just how many there are.

Boomy is the one where price is not the interesting clause. Its pitch has long leaned on distribution rather than on the audio, which means the terms worth reading are the distribution and payout ones rather than the free tier. Read the current version of them yourself. Ask what happens to a released track if you stop paying or close the account. That is where the surprise lives.

Soundful is aimed at creators who need background beds rather than songs with a story. The pattern is preview free, licence to actually use it attached to a plan. The free stage is an audition, not a supply.

Beatoven targets video and podcast scoring, where the whole product is being safe to publish. Expect the licence, not the generation, to be the paid object. That is a reasonable design and worth understanding rather than resenting.

Loudly pairs a library with a generator, and how much you may download depends on the plan you are on, so the same rule applies: the download is one permission, the right to use the download in a monetised video is a different one. Check that they match on the plan you are on.

Stable Audio has the most genuinely interesting free story on this list, and it is not the hosted free tier. There is an open model you can run yourself. That path has no subscription attached and costs hardware, setup and patience instead, and the model's own licence is a separate document from the hosted product's terms, so read the one that applies to what you are actually running.

The four traps, in the order they bite

"Free" and "free to publish" are different products. The generation being free says nothing about the licence attached to the output. Almost every restriction in this category is contractual. You will not hear it, the file will not refuse to upload, and nothing breaks. It simply means that if the track earns money, you were not allowed to do that.

The upgrade is not always retroactive. This is the expensive one. Some services treat the licence as a property of the moment the track was generated, not of your account today. If that is how the tool you picked works, then paying in March does not clean a February song, and your only fix is regenerating it on the paid plan and accepting that the new version is a different performance. Before you fall in love with a free tier output, find that clause.

Watermarks are mostly not what you think. The classic fear is a voice saying the brand name over your chorus, and that is rare. What is actually spreading is inaudible provenance marking and metadata that says a machine made this, plus platform side detection. Stripping it is not a clever workaround: most of these services prohibit it in their terms, and the account doing it is yours. Check what the service you are on actually says. Separately, several platforms and some jurisdictions now expect AI generated media to be disclosed, and meeting that requirement is on you wherever you publish.

The free allowance is not the real budget, the retries are. A generator does not hand you the song on attempt one. It hands you a draft, and you steer. Every vague brief costs a retry, retries cost runway, and runway is the thing free tiers ration hardest. Which is the entire argument for walking in with the words already finished.

None of the above is legal advice, and the terms differ by country, by tool and by which version of the document you agreed to. Read the page for the plan you are on, and if real money is riding on a release, ask a lawyer in your own jurisdiction rather than a blog.

The cheap route that actually ends in a song you can use

Not a survey, a pick. This is the order that wastes the least.

First, decide what the song is for before you open anything. A song for one person's birthday and a song for a monetised channel are not the same purchase, and only the second one has to survive a licence audit. If it is the birthday, a free tier is genuinely enough and you can stop reading.

Second, write the words before you spend a single generation. Not because we sell them, though we do, but because it is the only step where being precise is free of the credit meter. A brief that names the actual situation gets you a lyric with edges:

theme      the last shift at a bakery my grandmother ran for 31 years
emotion    longing, hope
POV        first
structure  classic
hook       title-line
vocal      female
language   en
age        45+

What comes back is a title and a full lyric, tagged and ready to paste. The opening verse and the chorus of one run:

[Verse 1]
Flour on the clock face, four in the morning chill
She knew the oven better than she knew how to sit still
Thirty one Decembers of the same blue apron string
And the bell above the door that never learned to sing

[Chorus]
Turn the sign to closed, let the last light go
Somebody has to say it, so I say it slow
The bread will still rise somewhere, the town will still be fed
But nobody proofs it like she did, nobody ever said

Third, pick one generator and pay that one, or stay free and stay non commercial on purpose. Farming three free tiers at once feels thrifty and is the most expensive option available: three sets of terms to track, three unfinished drafts, no runway anywhere. If the track has a job that involves money, buy the smallest paid month on the one tool that fits your genre, ship the thing, and cancel if you are done.

Fourth, keep the receipt. Save which plan you were on when a track was generated, with the date. If a platform asks later, that record is the whole answer, and reconstructing it from memory a year on is miserable.

If you want the ranking rather than the licence map, our comparison of Suno against the other generators does the which is better argument tool by tool. Either way the order holds: write the words first. One run of the generator is twenty cents and it buys back the retries a free tier rations hardest.

FAQ

Which AI music generator is genuinely free with no strings? Free of charge, plenty of them. Free of strings, none of the hosted ones, because the string is a licence rather than a price. The closest thing to no strings is running an open model yourself, where the cost moves from money to setup time and you read the model licence instead of a pricing page.

Can I sell a song I made on a free plan? Usually not, and that is the central restriction of the whole category. Check the terms of the specific tool and the specific plan, and check whether upgrading later fixes a track that already exists, because on some services it does not.

Do free AI songs have a watermark? Rarely an audible one. Increasingly an inaudible provenance signal or metadata, plus detection on the platform side. Removing it is a terms problem, not a technical trick, and several platforms expect a disclosure from you regardless.

Is the lyric free too? Ours is not, and that is deliberate: it costs twenty cents a generation, or nineteen dollars once and never again. What you get for it is text with no non commercial phase, usable commercially from the first line, which is exactly the thing the free music tiers withhold. There are free lyric tools, and they are a fair place to start if the song is for one person and never leaves the family chat.

Do I still need a music generator if I buy the lyric? Yes. We write words. We do not sing, we do not render audio, and we never will. The audio step happens in a tool you choose, most often Suno, which is a separate company operating under its own terms. Start with a brief in the generator, take the tagged lyric, and spend your free credits on performance instead of on guessing what to write.
