Suno vs CustomSongwriter vs Udio: two tools and one song

Two of these hand you a machine. One hands you a finished song. The choice is not really between them.

Casey LindstromPublished 24 September 2026, 6 min read

Suno scored 81 out of 100, CustomSongwriter 82, Udio 83, on the same rubric

Short answer

Two of these are tools and one is not. Suno and Udio hand you a machine and an afternoon. CustomSongwriter hands you one finished song and nothing else. If you want to make music, the third column is the wrong purchase. If you want one song about one person by Saturday, the first two are.

Disclosure. CustomSongwriter is run by the same people who run this site. It is scored against the same five criteria as the other seven entries, the reasoning sits in its full review, and there is no link to it anywhere on this site, including here. Read the two columns either side of it as the independent ones.

Full Udio review

One rubric, three totals, five criteria each. The middle column wins one criterion and loses three, which is the whole article in one picture.

The question these three actually answer

People search for Suno against Udio more than for any other pair in this market, and a good share of them are not choosing a tool at all. They want a song for a fiftieth birthday, a wedding, a leaving do. For that person the honest answer is that both tabs they have open are the wrong tabs, and the reason sits in what a generator is: a generator is a thing you operate. Nobody who wants one song for one Saturday wants a thing to operate.

So this page puts three answers next to each other instead of two. Two of them are software you drive, and the third is a person writing to a brief. They are not really competitors. They are answers to two different questions that people arrive at through the same search box.

The same seven questions asked of all three. The third row is where most people decide.
	Suno	CustomSongwriter	Udio
What you are buying	A tool, for as long as you pay	One finished song, once	A tool, for as long as you pay
Price	10 USD a month, 8 annually	29.99 USD once, nothing renews	10 USD a month, 8 annually
What you get free	50 credits a day, no download	The full lyric and the first 45 seconds	10 credits a day, private use only
Time to a finished song	About 30 seconds	Five to ten minutes	About 40 seconds
Can you revise it	Regenerate the whole track	Three free regenerations, by email	Yes, section by section
Documented singing languages	None published	Thirteen	None published
Who writes the words	You, or the model	A person, from your brief	You, or the model
Score on my rubric	81/100	82/100	83/100

Where Suno wins

Speed and hit rate. Across the same forty briefs Suno returned something usable on the first generation more often than anything else I tested, and thirty seconds later you are listening to it. Nothing on this page beats that feeling, and for a song you are making for yourself it is most of what matters.

It also has the largest free tier of the three by a distance: fifty credits a day is enough to form a real opinion before paying anybody. The full Suno review goes through what those credits do and do not allow.

Where Udio wins

Everything after the first generation. Udio is the only one of the three where a broken bridge is a small problem: mark the section, ask for it again, keep the verse you liked. On Suno the same problem means regenerating the whole track and hoping the good parts survive, which they often do not.

It also has four announced rightsholder agreements against Suno’s two, having settled with Universal in October 2025 before signing with Warner, Merlin and Kobalt. For a song going in front of a paying client that gap is the reason I reach past Suno.

Where the third column wins, and where it does not

It wins on exactly one thing, and it is the thing neither generator does at all: somebody reads your brief and writes words about the actual person. In my test the fiftieth-birthday brief named a daughter, and the lyric came back with her name spelled correctly on the first attempt. Both generators had to be told twice, and one of them rhymed the name with something nobody would sing out loud.

Everything else is a loss. There is no interface, so there is no experimenting and no second idea at eleven at night. There is one MP3 and no stems. Five to ten minutes is quick for a written song and slow next to thirty seconds. And at 29.99 dollars once it costs three months of either subscription, so from the third song onwards the subscription is simply cheaper and you still have the tool at the end.

How to choose in one line

If you enjoy the making, Suno. If you will revise what you make, Udio. If you do not want to make anything and you want a song about a person by a date, neither. That is the whole of it, and it is the same conclusion the the best AI music generator list reaches by a longer route.

Questions I get asked about these three

Questions people ask

Is CustomSongwriter better than Suno?

On one job, yes: one song, about one named person, for a date in the calendar, with no tool to learn. On every other job Suno is better and CustomSongwriter is the worst option of the three, because it gives you nothing to work with afterwards.

Which of the three is cheapest?

It depends on how many songs you want. Suno and Udio are ten dollars a month each. CustomSongwriter is 29.99 dollars once. One song: the one-off is dearer than a single month and you keep no tool. Three songs or more: the subscription wins and keeps winning.

Can I hear something before I pay?

All three, in different amounts. Suno gives fifty credits a day and no download. Udio gives ten a day. CustomSongwriter sends the whole lyric and the first forty-five seconds of the finished recording before asking for anything.

Which one can I sell music from?

Suno from the Pro tier, Udio from its entry paid tier, CustomSongwriter under a non-exclusive commercial licence included in the one payment. A vendor licence is not a copyright in any of the three cases, which the rights guide goes through properly.

I have written about music software since 2014, first for a regional print weekly and since 2019 on the web. I pay for every subscription on this site out of my own pocket, run each tool through the same brief before I write a word about it, and keep the raw exports so I can go back and check myself.
