Free AI Music Generators: Top 6 Tools Compared

Suno is the best free AI music generator for casual creators needing daily track generation, while Udio is the top choice for users focused on crafting full-length songs. Choosing the right platform depends entirely on your specific needs for downloadable files, commercial rights, and advanced editing features. The landscape of AI music creation offers several capable free tiers, but each comes with strict limitations on how you can use the generated audio. Below is a detailed comparison of six major platforms to help you find the exact tool for your workflow.

Suno offers a highly accessible entry point for AI music creation, operating on a daily credit system. As of 2026-08-21, the Free Plan provides 50 credits that renew daily, which is enough to generate 10 songs. Users on this tier get access to the v4.5-all model, standard features, a shared creation queue, and the ability to upload up to 8 minutes of audio.

However, the free tier comes with significant restrictions. There is no commercial use allowed, no stem separation, and no option to purchase add-on credits. Most notably, starting September 3, 2026, the Free Plan will no longer include monthly song downloads. To unlock commercial use rights, priority queuing for up to 10 songs at once, and downloads, users must upgrade to the Pro Plan ($8/month) or the Premier Plan ($24/month). Paid tiers also expand audio uploads to 30 minutes and unlock the ability to buy extra credits. The platform features Suno Studio, tools to co-write, and options to remix songs by extending, covering, or adjusting their speed.

Best for: Casual creators and hobbyists who want to experiment with daily generations and do not need to download their tracks or use them commercially.

Udio is a credit-based generator that focuses heavily on track structure and style referencing. As of 2026-08-21, Udio’s Free plan requires no credit card and provides 10 credits per day alongside a pool of 100 credits per month. Free users can generate up to 4 songs at once and are limited to 3 full-length (2:10) song generations per day. Credits never roll over on any tier.

The platform allows users to extend and remix songs, use Styles for musical reference, and record or upload their own audio. Moving to the Standard plan ($10/month, or $8/month billed annually) unlocks 2,400 monthly credits, Voice Control, custom cover art, and the ability to edit music and lyrics. It also grants access to premium Artist Styles, Blend Styles, and Reduce Styles. The Pro tier ($30/month, or $24/month annually) increases the limit to 6,000 credits and 10 concurrent generations. Extra credit packs can be purchased starting at $3.00 for 100 credits without changing your subscription.

Best for: Users who specifically want to generate and structure full-length songs for free, provided they can work within the strict daily and monthly credit caps.

Boomy positions itself as a streamlined song creation and editing platform. Its free tier is permanently labeled "FREE FOREVER" in the interface, rather than acting as a time-limited trial. This tier covers basic song creation and editing, allowing users to save up to 25 songs with 12 tracks per song. It even permits up to 3 monetized releases.

The major drawback of Boomy's free plan is that it allows no downloads at all and strictly prohibits commercial use outside of its specific monetization release system. As of 2026-08-21, upgrading to the Creator plan ($9.99/month) expands the limits to 500 song saves, 25 WAV downloads per month, and up to 15 monetized releases, while granting full commercial use of downloaded songs. The Pro plan ($29.99/month) offers unlimited song saves and 250 WAV downloads per month. Both paid tiers include advanced editing tools.

Best for: Creators who want to build and edit tracks directly in the browser and test out monetized releases before paying for a subscription.

Mubert specializes in text-to-music generation of royalty-free tracks, making it a popular choice for content creators. The free Ambassador plan provides 25 generations per month and allows 5 MP3 downloads per day. Tracks generated on this tier have a fixed length, generate one at a time, require obligatory attribution, and are strictly for non-commercial use.

As of 2026-08-21, Mubert's paid subscriptions start with the Creator plan at $14/month ($140 billed annually), which removes the daily download cap, increases the allowance to 500 generations per month, and unlocks custom track durations alongside lossless WAV exports without an audible watermark. Limited commercial use requires the Pro plan ($39/month), while full commercial use requires the Business plan ($199/month). Alternatively, Mubert offers one-time perpetual licenses starting at $19 for social media content. Note that on all plans, tracks are not licensed for Content ID, standalone streaming releases, or stock music sites, and purchases are non-refundable.

Best for: Video creators and streamers who need downloadable MP3 background music for non-commercial projects and are willing to provide attribution.

Riffusion offers a highly capable free tier that stands out for its file access. The $0/month plan includes daily top-up credits, allows 2 concurrent generations, and provides access to all core features. Crucially, this includes access to Lyria Models, Producer Projects, and the ability to download files in MP3, WAV, and M4A formats, as well as stem downloads.

For users who need higher volume, paid plans start with the Starter tier at $6/month as of 2026-08-21. This provides 3,000 monthly credits (roughly 600 songs) and 8 concurrent generations. The Plus plan ($18/month) offers 10,000 credits, and the Member plan ($48/month) provides 30,000 credits. Paid users also receive a Member badge, access to member events and swag, and early access to new features.

Best for: Producers and musicians who require free access to lossless WAV files and separated audio stems for further mixing in their own software.

Stable Audio integrates AI generation with traditional music production workflows. The platform notes in its FAQ that a free plan exists and renews on the first of each month. However, the specific limits of this free tier are not stated on the pricing page; because pricing changes often, you will need to check their site directly to see the current free allowances.

As of 2026-08-21, paid subscriptions start with the Solo plan at $12/month, which provides 660 credits per month. The Session plan costs $30/month for 1,800 credits, the Producer plan is $90/month for 6,000 credits, and the Studio plan is $199/month for 14,000 credits. Unused generations do not roll over to the next month on any plan. A major advantage of Stable Audio is that all plans—including the entry-level paid tier—come with full access to both the web app and the Stable Audio DAW plugin. Refunds are strictly limited to requests made within 48 hours with under 2% of the monthly allowance used.

Best for: Producers looking to integrate AI generation directly into their digital audio workstation via a plugin, provided they are willing to test the unlisted free limits first.

Selecting the right tool from this comparison set comes down to what you intend to do with the final audio. If your goal is high-volume daily experimentation, Suno provides the most generous daily refresh rate. If you are focused on crafting and structuring full-length tracks, Udio is the superior choice.

For users who need to take the audio offline, your options narrow. Riffusion is unmatched for producers because it offers free WAV and stem downloads. Mubert is highly effective for video creators who just need a quick MP3 and don't mind adding an attribution link. Conversely, if you want to build tracks in the browser and test the waters of monetization without downloading files, Boomy provides a unique pathway. Always review the commercial use restrictions on free tiers, as none of these platforms grant full commercial rights without a paid subscription or license.
