Correction, 2026-10-02: we gave Suno Pro as $8 a month and Premier as $24 a month. Those are the prices billed yearly; month to month they are $10 and $30. We also wrote that Suno's free plan includes no song downloads, where its pricing page says "No monthly song downloads". We counted MiniMax Music v2 (5 credits) as a music bed and used it for the low end of "ten bed options for 50 to 170 credits", but its lyrics field is required (10 to 3,000 characters), so it makes sung tracks, not instrumental beds. Ten 30-second instrumental options now cost 90 credits on MiniMax Music 3 or 130 on Lyria 2. We had said audio carries no marker of its license, while Suno's terms let it append a fingerprint, watermark or metadata that shows the tier. We removed judgments we had not measured (that Suno "makes the best-known music" and is "excellent" for discovery, that dedicated tools are "deeper instruments", that free tiers differ "more in rights than in sound", that beats are "the part AI audio does best") and an unsourced line that most free entries are trial credits that never renew, and added the free terms of Stable Audio, Mubert and ElevenLabs, checked on 2026-10-02. A second check the same day found an FAQ answer that still said a file does not announce its license, which contradicts the Suno and Mubert terms above; it now says a file rarely does. We also rewrote two generalizations we had not measured, that nobody remembers which tool made a downloaded track and that a standalone track's build lands two seconds after the cut's, as things that can happen.
Correction, 2026-09-30: Sonauto is now Treblo, and its free tier is confirmed from its own archived pages. We had also called MiniMax's free allowances generous without a source, could not quote Udio (its terms allow personal, non-commercial use only), priced MiniMax Music 3 per generation (it bills per second) and rated sound quality we have not tested. All fixed.
The best free AI music generator in 2026 depends on one question that has nothing to do with sound: can you use the track commercially? Suno's free tier is non-commercial, so a monetized video, a client ad, or a podcast with sponsors cannot legally use it. Treblo, the service formerly called Sonauto, is the free answer with rights, on its own archived pages: unlimited songs on its free tier, and terms that assign you the output with no usage restrictions. We have not run a side-by-side quality test of any tool here, so this guide does not rank sound; it ranks by what the license lets you ship. Disclosure: 8frame is our product, it is not a free music tool (a new account starts with no credits), and the last section covers when generating the bed inside your video workflow makes sense.
TL;DR
- Best free with rights: Treblo (formerly Sonauto). "Truly free. Unlimited songs with our latest model", and its terms give you ownership of what you make with no usage restrictions, even on the free tier. Treblo's live site returned HTTP 403 to our check on 2026-10-02, so this comes from its own pages as archived in August and September 2026
- Free without rights: Suno. The free plan gives "50 credits per day", with "No monthly song downloads" and "No commercial rights". Commercial use starts on Pro, $8 a month billed yearly or $10 month to month, and covers only the songs you download within your allowance: 20 a month on Pro, 60 on Premier ($24 billed yearly, $30 month to month)
- Udio: 10 free credits a day and 100 a month, but its terms limit output to personal, non-commercial use on every plan
- Stable Audio, Mubert, ElevenLabs: free tiers for personal or non-commercial use only. Commercial use starts on Stable Audio Solo ($12 a month), Mubert Pro ($39 a month, or $32.49 a month billed annually) and ElevenLabs Starter ($6 a month)
- MiniMax: its audio terms say logged-in users may get daily time-limited free credits; the amount is not published, and free output should be treated as personal use
- The rule: the license, not the audio, decides whether a free track can ship. Judge the sound on your own prompt; read the rights in writing
- Inside a video workflow: on 8frame, a 30-second bed without vocals is 9 credits on MiniMax Music 3 with the
[instrumental]tag, or 13 on Lyria 2 (one 30-second clip per generation), with commercial use cleared on paid plans. MiniMax Music v2 is 5 credits but needs lyrics, so it sings
The license problem, stated plainly
AI music free tiers split into three license shapes. Non-commercial (the free tiers of Suno, Udio, Stable Audio, Mubert and ElevenLabs): use it in anything that earns money and you are outside the license. Commercial with conditions: attribution, platform limits, or download caps. Suno's paid plans cover only the songs you download within your allowance, and Mubert bars streaming releases and Content ID registration on every plan. Ownership with no usage restrictions (Treblo's terms, which assign you the output even on the free tier): use it, including in ads and monetized content.
The trap is that a file rarely announces its license. Suno's terms let it append a fingerprint, watermark or metadata that shows the tier, and Mubert's free plan carries an audible watermark, but most beds look like any other audio file in a project folder. Three months after the download, it is easy to lose track of which tool made which bed, and that is how a non-commercial track can end up in client work. If you use free tiers across several tools, log the source with the file, the same discipline as organizing creative assets.
The picks
1. Treblo (formerly Sonauto)
Sonauto renamed itself Treblo in June 2026 and moved to treblo.com; sonauto.ai still redirects there. Treblo's homepage offered "$0.00 Truly free. Unlimited songs with our latest model" with "No daily limits", and its FAQ answers "Can I use my songs outside Treblo?" with "Yes, even on the free tier. We place no usage restrictions on songs you create". Its terms, dated 2026-08-20, assign you the output and make no free or paid distinction.
The live site returned HTTP 403 to our check on 2026-10-02, so every quote here comes from Treblo's own pages as archived on 2026-08-21 and 2026-09-23. Check treblo.com before shipping commercial work on it. We have not tested its output, so we do not rate the sound; on its archived terms, for a free tool with shippable rights, this is the pick.
2. Suno free tier
The free tier you cannot ship: Suno's terms (effective 2026-09-03) limit free-tier output to "lawful, personal and non-commercial purposes", and the free plan lists "No monthly song downloads". Paid commercial use is tied to downloads too: Pro ($8 a month billed yearly, $10 month to month) includes 20 song downloads a month and Premier ($24 billed yearly, $30 month to month) includes 60. Use the free tier to find the direction (genre, tempo, energy), then either pay Suno for the rights or recreate the brief elsewhere. Shipping free-tier output in paid work is outside the license, and Suno reserves the right to mark each output with its tier.
3. MiniMax Music apps
MiniMax's audio terms say that logged-in free users "may receive daily time-limited free credits", without a published amount for music. We could not read a current statement of rights on free output, so treat free MiniMax tracks as personal use until its terms say otherwise.
Udio, Stable Audio, Mubert and ElevenLabs
Udio gives 10 credits a day and 100 a month on its free plan, with up to three full-length (2:10) songs a day. Its terms (last revised 2025-11-12) allow output "solely for your personal and non-commercial purposes" and bar downloading copies, with no exception for paid plans, so it is not a source of shippable audio.
Stable Audio gives 50 credits a month, which Stability puts at "About 12 full-mix generations", for "Personal, non-commercial use". The commercial license starts on Solo at $12 a month.
Mubert's free Ambassador plan gives 25 generations and 5 MP3 downloads a month at a fixed length, with an audible watermark and attribution required, for non-commercial use. Monetized content needs Pro, listed at $39 a month or $32.49 a month billed annually. On every plan, Mubert bars publishing tracks to streaming services such as Spotify and registering them in Content ID.
ElevenLabs' free plan has 10k credits a month and includes Music, which ElevenLabs lists at about 900 credits a minute, so roughly 11 minutes a month. The Commercial License and "Music commercial use" start on Starter, $6 a month.
A tool not on this list should be judged on the same two axes: how it sounds on your own prompt, and what the license lets you ship. These terms were read on 2026-10-02; read the tier's own terms again on the day you sign up.
The workflow question
Standalone music tools share a shape: generate there, download, carry the file into the edit, and only then hear whether the track's build lands with your cut's. Music chosen without the picture can fight the picture, which is why how to pick music for a brand video argues for auditioning against the cut.
Generating the bed where the video already is closes that loop. Canon 8frame prices; a credit is about $0.01 at pack rate:
| Route | Credits | Notes |
|---|---|---|
| MiniMax Music 3 | 0.27 a second of the length you request | 30 seconds 9, 60 seconds 17, 180 seconds 49, 300 seconds 81; the model may stop before the requested length. The lyrics field is required: for a bed without vocals, use the [instrumental] tag |
| Lyria 2 | 13 per generation | Each generation is one 30-second clip. Prompt only, no lyrics field |
| MiniMax Music v2 | 5 per generation | The lyrics field is required (10 to 3,000 characters), so it makes sung tracks, not instrumental beds |
| ElevenLabs Music | 81 per started minute | 3 seconds to 10 minutes; a 30-second track still bills 81. Say "instrumental" in the prompt for no vocals |
All of it sits on the same canvas as the footage, with commercial use cleared on paid plans. Ten 30-second bed options auditioned against the actual cut cost 90 credits on MiniMax Music 3 or 130 on Lyria 2, about $0.90 to $1.30; ten 60-second takes on MiniMax Music 3 cost 170, about $1.70. That is the opposite of the standalone workflow, where you audition blind and license after.
The limit runs the other way too: if the music is the product (an artist project, a release with vocals you care about), the questions change to who owns the master and whether the terms allow distribution. A music tool on a paid plan whose terms cover releases, or a human composer, is the right spend. Read the distribution clause, not just the commercial-use line: Mubert, for one, bars streaming releases and Content ID on every plan.
FAQ
Can I use free AI music in monetized videos? Only if the specific tool's terms say so. Treblo's archived terms allow it even on the free tier; the free tiers of Suno, Udio, Stable Audio, Mubert and ElevenLabs do not, and Udio's terms allow personal, non-commercial use only on every plan. A file rarely announces its license, which is exactly why this gets missed.
What is the best free AI music generator for commercial use? Treblo (formerly Sonauto), on the combination of unlimited free songs and terms that assign you the output with no usage restrictions. Its live site returned HTTP 403 to our check on 2026-10-02, so verify on treblo.com before shipping.
How much does Suno cost for commercial use? Pro is $8 a month billed yearly or $10 month to month, and Premier is $24 billed yearly or $30 month to month. Commercial use covers the songs you download within the plan's allowance: 20 a month on Pro, 60 on Premier. The free plan has "No commercial rights".
Can I make an instrumental bed with MiniMax Music v2 on 8frame?
No: its lyrics field is required, so it makes sung tracks. For a bed without vocals, use MiniMax Music 3 with the [instrumental] tag (9 credits for 30 seconds) or Lyria 2 (13 per 30-second clip).
Is AI music actually royalty-free? "Royalty-free" describes the license a tool grants, not a property of AI music in general. Each tool's terms govern its own output, and paid tiers usually grant more than free ones.
