TL;DR
"Free AI music generator" means one of two things: a free tier on a paid product, or a tool that only makes background loops. Every full-song generator worth using — the ones that write lyrics and sing them — is the first kind, and none of their free tiers include commercial rights; free is for making and listening. So compare them on what the free run teaches you and on what the upgrade costs when you need to publish. On Suno AI Music a new account gets 16 credits — two complete songs with vocals, no card — on Suno v4.5, and the paid plans add the PRO models, downloads and the commercial licence.

What "free" means here
Three tests, applied to every tool below:
- Does it make a complete song — lyrics, vocals, arrangement — from a description? Or does it make instrumental beds and loops? Both are useful; they are different products.
- How much do you get before paying? A daily allowance, a monthly one, or a one-time gift. Each shapes how you can use the tier.
- May you use the free output commercially? In a monetised video, a podcast with sponsors, a client project, a release on Spotify. This is where "free" stops being free.
Limits below are as published on each product's pricing page at the time of writing (September 2026). They change; check the page before you plan around a number.
The comparison table
| Tool | Full songs with vocals | Free allowance | Commercial use on free | Best for |
|---|---|---|---|---|
| Suno AI Music | Yes | 16 credits on signup = 2 songs (two takes) | No — paid plans | Trying a full vocal song, then editing it (extend, cover, replace, stems) |
| Suno | Yes | 50 credits a day ≈ 10 songs, v4.5 | No — Pro/Premier | Volume on the free tier |
| Udio | Yes | 10 credits a day + 100 a month ≈ 3 short songs a day | No | Fine control of the generation |
| Mureka | Yes | 4 songs a day, no downloads | No — paid credits | Stem separation workflows |
| Stable Audio | Instrumental / sound design | 10 credits | No | Short instrumentals and effects |
| AIVA | Instrumental (MIDI-editable) | 3 downloads a month | No | Classical / cinematic cues you can edit as MIDI |
| Boomy | Simple songs | Unlimited creates, 25 saves, 1 release | Limited | Quick playful tracks |
| Mubert | Instrumental beds | Free "Ambassador" tier | No — explicitly excluded | Streaming background music |
One tool many older lists still include, Riffusion, rebranded and was acquired in 2026; its site now redirects elsewhere, so it is left out.
Read the table for the shape of each free tier rather than the exact numbers. A daily allowance rewards showing up every day and forgets whatever you did not use; a monthly pool suits bursts of work; a one-time gift is an audition — enough to hear the model, not enough to build a catalogue on. Which shape suits you depends on whether you make music in a habit or in a weekend.
Full-song generators
These are the tools that give you a record: a song with a singer and a chorus you can hum. All four are description-driven, all four return more than one take per run, and all four keep commercial rights for the paid plans.
Suno AI Music. A one-time 16 credits on signup — one generation is 10 and returns two complete takes, so you get two songs and a few lyric drafts before deciding anything. Generation runs on Suno v4.5; v5 and v5.5 are PRO. What sets it apart is what happens after the free run: every song sits in a library that the editing tools read from, so the same account can extend the song, cover it in another style, replace a weak section or separate the vocals, each for the same 10 credits. Downloads and the commercial licence — certificate included — come with the paid plans.
Suno. The original. The Free plan lists 50 credits renewed daily, which Suno describes as about 10 songs a day, on its v4.5-era model, with a shared queue, no add-on credit purchases, and personal use only. The newer models and commercial rights are on Pro and Premier. If you want to make many songs a day for free and never publish them, this is the most generous allowance on the list.
Udio. Free tier of 10 credits a day plus 100 a month — around three short songs a day — for personal use. Udio's strength is control: extension, inpainting and stem downloads are part of the workflow on the paid plans, and its trending feed is a good place to hear what the model does well.
Mureka. Four songs a day on the free plan, with no downloads and no commercial use; paid credits bring commercial rights and the stem-separation tools it is known for. A good second opinion when a prompt sounds one way on Suno and you want to hear another model's take.
Background and instrumental tools
If the song is a bed under something else — a stream, a video, a presentation — you may not need vocals at all, and these tools are built for exactly that.
Stable Audio makes short instrumentals and sound design from a prompt; the free credits are enough to learn what it does. AIVA composes classical and cinematic cues and exports MIDI you can edit, with three free downloads a month for personal use. Boomy is the fastest route to a playful, simple track and lets you save a handful and release one. Mubert generates endless background beds and is popular with streamers, but its free tier explicitly rules out commercial, branded and ad use.
For any of these uses, the instrumental switch on a full-song generator does the same job — on Suno AI Music it is one toggle, and the vocal remover can also strip the voice off a song you already like.
The commercial-use question
This is the line every free tier draws in the same place: you may make it, you may not sell it or put it under something that makes money. Monetised YouTube, sponsored podcasts, client work, ads, and releases on streaming platforms all count as commercial. The free tiers above are for learning, sketching and personal listening.
Two practical consequences:
- Decide by the upgrade, not by the free tier. The free run tells you which model's sound you like. The plan tells you what publishing costs. Pick the tool whose paid plan you would actually buy.
- Get the licence in writing. On the paid plans here, every song comes with a downloadable licence certificate; covers, extensions and stems inherit the licence of the song they came from. If a platform or a client asks who owns the music, that document is the answer.
How to get the most out of a free tier
- Spend the first run on a prompt you can judge. A genre you know well tells you more about the model than one you do not.
- Listen to both takes. Every generator returns more than one; the second is often the better one.
- Change one thing per run. On a small allowance, a run that changes one variable is a lesson; a run that changes five is a guess.
- Use the cheap tools. On Suno AI Music a lyric draft is 1 credit — write the words before you spend 10 on the music.
- Keep the sketches. A free-tier song you like can be extended or covered later, on the same account, once you have credits — the library is the point.
FAQ
Is there a free AI music generator with commercial rights?
Not among the mainstream full-song generators. Free tiers are for personal use; commercial rights come with the paid plans. If a tool advertises otherwise, read the licence line by line before you publish.
How many songs can I make for free?
It depends on the tool: Suno gives about 10 a day, Udio about 3 a day, Mureka 4 a day, and Suno AI Music two complete songs on signup with two takes each. See the table.
Which free tier is the most generous?
Suno's, by volume. Suno AI Music's is a one-time gift rather than a daily allowance, but it includes the editing tools on the same account, which is what most people end up paying for.
Do free-tier songs have vocals?
On the full-song generators, yes — Suno, Udio, Mureka and Suno AI Music all sing. Stable Audio, AIVA and Mubert are instrumental tools.
Can I download free-tier songs?
Varies: Mureka's free tier has no downloads; Suno AI Music's downloads come with the paid plans; the others allow limited downloads for personal use. Check each pricing page.
What happens to my songs if I upgrade later?
On Suno AI Music the library is the same account, so anything you made on the free tier can be extended, covered or licensed once you are on a plan.
Final take
Free tiers are auditions. Use them to hear which model makes the sound you want, listen to both takes, change one thing at a time — then buy the plan whose licence matches where the song is going.
