Best AI Music Generators (2026): Suno, Udio, Flow Music and Treblo, Priced

Short answer: the best AI music generators in 2026 are Suno if you want the most-used song generator and can pay $8 a month for downloads and commercial rights, Flow Music (formerly Riffusion) if you want the cheapest paid plan at $6 a month for about 600 songs plus stems and WAV even on the free plan, Treblo (formerly Sonauto) if you want unlimited free songs you can download, and Udio if you want style references and song editing from $10 a month. If you already have a song and need it mixed and mastered, Cryo Mix is a different kind of tool, covered at the end. Updated November 3, 2026.

How we checked: plans, prices and limits come from each vendor's own pricing, FAQ or developer pages, read November 3, 2026. We did not generate the same song in every tool, so this guide compares plans, prices and features, not sound quality. Prices are in US dollars and change often; check the vendor before you pay. This guide covers songs only. If you want a video for your track, see our guide to AI music video generators.

Stork pulled estimated Google search traffic for each tool's domain from DataForSEO Labs on November 2, 2026. These are estimates of visits from Google search, not user counts, but the direction is clear. Suno is the giant: about 3.8 million a month in July and about 4.1 million in October. Flow Music's domain went from about 70,000 a month in July to about 432,000 in October, the fastest climb in this group. Treblo grew from about 1,600 to about 18,000 after its June rename, and Cryo Mix from about 4,500 to about 13,000. Udio moved the other way, from about 177,000 to about 161,000.

Demand for the category itself is large: in Google Ads data, "ai music generator" averaged about 90,500 US searches a month and "ai song generator" about 74,000 (monthly data ends September 2026).

Suno is the best-known AI song generator. Its pricing page, read November 3, 2026, lists three plans:

• Free: 50 credits a day on the free models (v6-mini is the best free model), 4 songs at once in a shared queue. No song downloads, no stem separation, no commercial rights.
• Pro, $8 a month: 2,500 credits a month, 20 song downloads a month, commercial rights, the best models and editing tools, two kinds of stem separation, custom models and voice recording. Billing yearly saves $24 a year.
• Premier, $24 a month: 10,000 credits, 60 downloads a month, Suno Studio, a third stem-separation type and adding vocals or instrumentals to existing songs. Billing yearly saves $72 a year.

The catch is the download meter. Credits and downloads are counted separately, so even on Pro you can make far more songs than you can download; extra downloads and credits are sold as add-ons. Plan credits do not roll over, and purchased top-ups do not expire but need an active subscription to use. Pick Suno if you want the largest community and the most features, and you are happy to pay for the songs you keep.

Flow Music started as Riffusion, became Producer.ai, and now lives at flowmusic.app. Its terms and privacy links lead to Google's policies. Songs come from Google's Lyria 3.5 model, and the same account can turn a track into a video with Veo. Instead of one prompt box you work with a chat co-producer: ask for a song, then change it by talking, extend it, remix it or split it into stems.

The pricing page, read November 3, 2026, marks every feature on every plan, including free: downloads in MP3, WAV and M4A, stem downloads and publishing. Plans differ in credits and concurrency. Free has daily top-up credits and 2 generations at once. Starter is $6 a month for 3,000 credits (about 600 songs, roughly 1 cent a song by the page's own estimate), Plus is $18 for about 2,000 songs and Member is $48 for about 6,000. Extra credit packs need an active paid plan.

Two cautions. The pricing page says nothing about commercial use per plan, so read Google's terms before you release a track. And a Fast.io review reports that songs cap at about three minutes and that some paid users had locked accounts.

Treblo is the renamed Sonauto, run by Sonauto, Inc. on its own music model. For people making songs in the app it is free: the homepage and FAQ promise unlimited songs on the latest model with no credits and no daily limits, and downloads in OGG, MP3, WAV, FLAC and M4A with no usage restrictions. You build a prompt from a list of 4,160 style tags, add lyrics or let it write them, then edit sections, extend, cover, remix or separate stems. There is an iOS app.

There is no paid consumer plan. Developers pay for the API: Starter is $11 a month for 200 songs and Pro $88 for 1,600, about 5.5 cents a song, with pay-as-you-go at about 6 cents. Products built on the API must credit Treblo. The limits are honest ones: Treblo itself says Japanese, Korean, Chinese, Arabic, Russian and Hindi work but pronunciation may be off, and it is a four-person team, so do not expect a support desk.

Udio sells song generation with editing tools. Its pricing page, read November 3, 2026:

• Free: 10 credits a day and 100 a month, no rollover, up to 4 songs at once, and a limit of 3 full-length (2:10) songs a day.
• Standard, $10 a month or $8 a month billed yearly ($96): 2,400 credits a month, 2-minute songs without the 3-a-day limit, voice control, editing music and lyrics, songs from uploaded audio, using existing songs as a style reference and custom cover art.
• Pro, $30 a month or $24 billed yearly ($288): 6,000 credits a month, 10 songs at once and every feature, including premium Artist Styles.

Extra credits cost $3 for 100 or $25 for 1,000. The pricing page does not mention downloads or commercial rights at all, so check Udio's terms before you plan to release anything made there.

Cryo Mix does not write music. You upload a stereo mix or up to 32 stems, it balances and masters the track for streaming, and you can ask its assistant Nova for changes such as brighter vocals. It is useful after a generator: split an AI song into stems, then rebuild and master it. Previews are free and unlimited (watermarked); a credit is charged only when you download. On its pricing page, read November 3, 2026, Starter is $9 a month for 2 credits ($4.50 a song) and Pro $39 for 30 ($1.30), and the Pro Annual plan at $199 a year for 370 credits brings it to about 54 cents a song. Cryo Mix says it never trains on uploaded music and takes no royalties.

• You want to release songs commercially: Suno Pro states commercial rights on its pricing page; budget for its 20-download cap. Treblo says its free songs carry no usage restrictions.
• You want the most songs per dollar: Flow Music Starter at $6 for about 600 songs, after reading Google's terms on rights.
• You want to pay nothing: Treblo for unlimited downloadable songs; Flow Music for a daily allowance with stems.
• You like to steer a song with a reference track: Udio Standard.
• You sing in Japanese, Korean, Chinese, Arabic, Russian or Hindi: test a few songs on the free tiers before paying. Treblo flags these languages itself, and the Fast.io review says Flow Music mispronounces non-English lyrics.
• You already have the song: Cryo Mix to mix and master it, previews free.

One rule across all of them: plan credits expire at the end of each month on every paid plan above, so buy the tier you will use every month, not the one with the biggest number.
