Suno vs Udio: what actually differs
Plan details read from both pricing pages on 2026-10-08. Prices and credit allowances change - check the provider's current page before you commit.
Suno and Udio are the two best-known prompt-to-song generators, and on a features list they look nearly identical: describe a track, get a finished song with vocals, pay by credits. The differences that decide the choice are in the plans, the editing tools and the rights attached to the output - not in the pitch.
What they have in common
- Both are prompt-to-song generators: you describe a track and the model returns a finished song with vocals and instrumentation.
- Both run a credits-based freemium model, and on both the included credits do not roll over - unused credits are lost at the end of the period.
- Both were named in the RIAA's June 2024 lawsuit alleging that they trained on copyrighted sound recordings.
- Both let you extend and remix generated tracks, and both offer monthly downloads only on paid plans.
Where they differ
| Axis | Suno | Udio |
|---|---|---|
| Free tier | 50 credits a day on the free model only; no monthly downloads; no commercial rights | 10 credits a day (100 a month), up to 3 full-length 2:10 songs a day, 4 generations at once |
| Entry paid plan | Pro - $8/mo billed annually ($10 month-to-month): 2,500 credits/mo, 20 downloads/mo, commercial rights | Standard - $8/mo billed annually ($10 month-to-month): 2,400 credits/mo, 6 generations at once |
| Top plan | Premier - $24/mo billed annually ($30 month-to-month): 10,000 credits/mo, 60 downloads/mo, Suno Studio | Pro - $24/mo billed annually ($30 month-to-month): 6,000 credits/mo, 10 generations at once |
| Credits roll over? | No - included credits do not carry over day to day or month to month; purchased top-ups do not expire but need an active subscription | No - credits do not roll over |
| Editing and control | Suno Studio multitrack timeline with MIDI, effects and automation; 2 stem-separation types on Pro and 3 on Premier; record or upload your own voice; train custom models | Voice Control, edit music and lyrics, upload your own audio, use songs as a style reference, blend styles, extend and remix, generate cover art |
| Commercial rights | Included from the Pro plan upward | Not stated on its public pricing page - verify against the plan terms before you publish |
Read together: at the same price the two are close on credits, but Suno bundles an editor and commercial rights into its paid tiers while Udio stays a generation tool. If the plan is to release the track, the rights column is the one that matters; if the plan is a lot of generations on one prompt idea, the credits column is.
The part neither one covers
Both are generation tools. Neither gives the finished track a place to be listened to, organized, or promoted - the output is a file you carry somewhere else. If discovery, continuous listening and creator promotion are part of what you want, that is a streaming platform with generation inside it rather than a generator.
A third option: EchoLoRA
EchoLoRA is an AI music platform rather than a generator: songs are generated from a prompt, then streamed through personalized radio and a catalog organized by genre, language and country, with a Creator Portal for publishing releases and an advertising market for promotion. It is free with no credit card, on web, iOS and Android, plus 24/7 live channels.
Stated plainly: EchoLoRA's published terms cover personal, non-commercial listening and discovery. Commercial use, bulk access and redistribution require prior written authorization - so for a track you intend to sell, one of the generators above with commercial rights on your plan is the better fit.
Frequently asked questions
Which is better, Suno or Udio?
It depends on the work rather than the brand. Suno's top tier adds a multitrack studio with MIDI export, more stem-separation options and more monthly downloads; Udio's tiers are a straightforward credit ladder. Both have a free tier, which is the cheapest way to judge the model on your own prompt.
Do Suno and Udio credits roll over?
No, on both. Unused included credits expire at the end of the day or month depending on the plan. On Suno, separately purchased top-up credits do not expire but require an active subscription to use.
Can I use Suno or Udio songs commercially?
Suno includes commercial rights from the Pro plan upward; its free tier explicitly excludes them. Udio's public pricing page does not state commercial-rights terms, so check the terms attached to your plan before you release anything commercially.
Are Suno and Udio being sued?
Both were named in the RIAA's June 2024 lawsuit alleging training on copyrighted recordings. Suno has since settled and signed licensing deals with Warner Music Group and BMG, while Universal Music Group and Sony Music remain plaintiffs and filed a second suit in September 2026 covering Suno's v6 models.
Is there a free alternative that also streams the music?
Yes. EchoLoRA is free with no credit card, generates original songs, and streams them through personalized radio and a catalog organized by genre, language and country. Its published terms cover personal, non-commercial listening, so it is a listening and discovery platform rather than a commercial-release tool.
