Sonauto AI Pricing 2026: Is Sonauto Free? Plans, Limits & Features Explained

Sonauto AI Pricing: Quick Answer

Is Sonauto free? YES. Sonauto (now rebranded as Treblo) offers completely free, unlimited music generation with their latest Melodia v3 model as of August 2026. Unlike competitors like Suno and Udio that limit free users with credits, Sonauto has no credit system, no daily caps, and no paywalls.

Here’s what you get for $0.00:

• Unlimited songs per month (no artificial limits)
• Latest Melodia v3 model access
• Full-length songs up to 4.5 minutes
• All download formats: OGG, MP3, WAV, FLAC, M4A
• Advanced features: Generation, inpainting, extending, stem separation
• No usage restrictions (from Sonauto’s side)

This pricing structure makes Sonauto the most generous free AI music generator on the market in 2026. But is it too good to be true? Let’s dive into the details.

Important context: Sonauto rebranded to “Treblo” in early 2026, but the platform remains the same. The official website is now treblo.com, though sonauto.ai still redirects correctly. For this article, we’ll use both names interchangeably since many users still search for “Sonauto.”

This comprehensive guide is based on our complete Sonauto AI review where we tested the platform extensively over 30 days, generating 150+ songs across multiple genres.

Is Sonauto AI Free?

Yes, Sonauto AI is 100% free and offers unlimited music generation with no credit system, no daily limits, and no paywalls. This is not a limited trial or a “first 3 free” gimmick—it’s genuinely free, unlimited music creation.

Here’s what makes Sonauto’s free tier unprecedented:

✅ What “Free” Actually Means at Sonauto

• No credit system: Unlike Suno (50 credits/day) or Udio (1,200 credits/month), Sonauto has zero credits to manage
• No daily caps: Generate 10 songs or 100 songs in a day—there’s no artificial limit
• No account verification: Start creating immediately without credit card verification
• No watermarks: Your generated songs are clean, without “free tier” branding
• No quality degradation: Free users get the same Melodia v3 model as everyone else
• No feature lockouts: Access to inpainting, extending, and stem separation—all free

⚠️ The Fine Print

While Sonauto is genuinely free, there are a few practical considerations:

• Queue delays: During peak hours (typically US afternoons/evenings), generation times may increase from 60 seconds to 2-3 minutes
• Server load: On rare occasions, heavy server load may slow down processing
• Commercial use: Licensing terms are unclear for commercial projects (more on this below)
• Future changes: As a VC-backed startup, pricing could change in the future (though nothing announced as of August 2026)

What Does Sonauto’s Free Plan Include?

Sonauto’s free plan is surprisingly comprehensive. Here’s every feature you get at $0/month:

Sonauto Paid Plans

Here’s where things get interesting: Sonauto currently has no paid consumer plans for individual users through their web interface.

However, they do offer a Developer API for commercial applications:

Melodia API for Developers

Who is the API for?

• App developers integrating AI music generation
• SaaS platforms offering music creation
• Content creation tools needing background music
• Businesses requiring high-volume generation with commercial rights

What About Sonauto “Pro” Plans?

Some older sources reference Sonauto “Starter,” “Pro,” and “Scale” plans with credit-based pricing ($11/month, $88/month, $330/month). These plans are no longer offered as of August 2026. Sonauto pivoted to the unlimited free model for consumers and API-only for commercial users.

Sonauto Free vs Paid

Since Sonauto no longer offers traditional consumer “paid plans,” let’s compare the free web app versus the developer API:

Should You Pay for the API?

The Melodia API makes sense if:

• ✅ You’re building a product/app that generates music
• ✅ You need programmatic access and automation
• ✅ You require clear commercial licensing
• ✅ You’re generating high volumes (100+ songs/month)
• ✅ You need guaranteed fast generation times

Stick with the free web app if:

• ✅ You’re creating music manually for personal projects
• ✅ You don’t need commercial rights clarity
• ✅ You’re testing AI music generation
• ✅ You’re a content creator making YouTube/social media content
• ✅ Budget is $0

Sonauto Usage Limits and Credits

One of Sonauto’s biggest selling points is the absence of a credit system. Let’s break down exactly what that means:

No Credit System

Unlike Suno (which uses credits: 1 song = 5 credits) or Udio (which uses credits: 1 generation = 10 credits), Sonauto has zero credits to manage, track, or run out of.

What this means in practice:

• No counting how many songs you’ve generated today
• No waiting until midnight for credits to refresh
• No anxiety about “wasting” a credit on a bad generation
• No upgrading because you ran out of credits

Practical Usage Patterns

Based on our 30-day testing period generating 150+ songs, here’s what we observed:

Real-World Generation Limits

While technically “unlimited,” here are the practical constraints we encountered:

• Concurrent generations: 4 songs in shared queue (vs. 10 in Suno’s priority queue)
• Browser limits: Generating hundreds of songs in one session may cause browser slowdown
• Server throttling: On 2 occasions during peak hours, we experienced 5-10 minute delays
• Failure rate: 5.3% of generations failed (142/150 succeeded)—comparable to competitors

What Features Are Included?

Let’s dive deep into Sonauto’s feature set and how it compares to competitors. This section covers everything you need to know about what Sonauto can actually do.

🎵 Core Music Generation Features

1. Text-to-Music with Vocals

Sonauto’s flagship feature: describe what you want, and it generates a complete song with lyrics and vocals.

Example prompts that work well:

• “A melancholic indie folk song about lost love, female vocals, acoustic guitar, 120 BPM”
• “Upbeat synthwave track with 80s vibes, male vocals, cyberpunk atmosphere”
• “Dark trap beat with heavy 808s, aggressive male rap vocals, minor key”

Quality rating: 9.2/10

2. Custom Lyrics Mode

Write your own lyrics and let Sonauto handle the music, melody, and vocal performance.

How it works:

• Paste your lyrics into the “Fancy Mode” interface
• Specify genre/style tags (electronic, pop, rock, etc.)
• Sonauto sets your lyrics to music with appropriate melody and vocals
• Success rate: ~85% of generations matched lyric structure correctly

Quality rating: 8.5/10

3. Instrumental-Only Mode

Generate music without vocals—perfect for background music, podcasts, or YouTube videos.

Use cases:

• YouTube background music
• Podcast intros/outros
• Video game soundtracks
• Study/work music
• Ambient/atmospheric tracks

Quality rating: 9.0/10

🎹 Advanced Editing Features

4. Inpainting (Section Editing)

Edit specific sections of a generated song. Don’t like the chorus? Regenerate just that part while keeping the rest.

How it works:

• Select a time range in your generated song
• Provide new instructions for that section
• Sonauto regenerates only that part, blending it with the original
• Success rate: ~80% achieve seamless blending (occasional audio artifacts)

Competitor comparison: Suno offers similar “replace section” editing. Udio’s version is more granular.

5. Song Extension

Extend your songs by adding intros, outros, or extending any section.

Extension options:

• Add intro (prepend audio)
• Add outro (append audio)
• Extend any section
• Build songs up to 4.5 minutes total

Performance: Extensions blend smoothly 80% of the time. Occasionally you’ll hear a slight audio “seam.”

6. Stem Separation (FREE!)

This is a killer feature: separate any generated song into individual stems (tracks) for remixing in a DAW.

Available stems:

• Vocals (lead and backing)
• Drums/percussion
• Bass
• Other instruments (guitars, synths, etc.)

Why this matters: Stem separation typically costs extra ($10-30/month on other platforms). Sonauto includes it free.

Quality rating: 8.8/10 — Clean separation with minimal audio artifacts

🎨 Style and Genre Control

7. 4,160+ Style Tags

Sonauto supports thousands of genre and style tags you can mix and match.

Popular style combinations we tested:

• Electronic + Synthwave + 80s
• Rock + Indie + Lo-Fi
• Hip-Hop + Trap + 808
• Folk + Acoustic + Melancholic
• Metal + Death + Aggressive
• Pop + K-Pop + Upbeat
• Jazz + Smooth + Noir

Genre fusion: Sonauto excels at blending genres. Want a “death metal sea shanty”? It can do it (and it’s surprisingly good).

💾 Export and Download Options

8. All Audio Formats Included

• OGG (compressed, open-source)
• MP3 (universal compatibility)
• WAV (lossless, professional quality)
• FLAC (lossless compression)
• M4A (Apple/iTunes optimized)

• M4A: ~4-6 MB

🌐 Community and Sharing

9. Public Profiles and Groups

Sonauto includes social features:

• Publish songs to your public profile
• Join genre-specific groups
• Discover what other creators are making
• Share direct links to your songs

Privacy note: You control what’s public. You can keep songs private or share them selectively.

Is Sonauto AI Music Generation Unlimited?

Yes, Sonauto music generation is truly unlimited—with some practical caveats.

Let me break down what “unlimited” actually means in practice, based on our extensive testing:

✅ What IS Unlimited

• No hard caps: There’s no technical limit on how many songs you can generate per day, week, or month
• No credit system: You don’t need to manage, purchase, or wait for credits to refresh
• No paywalls: Features aren’t locked behind “generate 5 free, then pay”
• No account tiers: Every user has the same unlimited access (no “premium” users cutting in line)

⚠️ Practical Limitations

While technically unlimited, you may encounter:

• Queue delays: During peak hours (US afternoons), generation times increase from 60 seconds to 2-3 minutes
• Shared queue: You’re in a shared queue with other free users (4 concurrent generations vs. Suno Pro’s 10)
• Server throttling: Extremely heavy usage (100+ songs in rapid succession) may trigger temporary slowdowns
• Browser limits: Generating hundreds of songs without refreshing the page can cause UI slowdown

Real-World Testing Results

Over our 30-day testing period, we generated 150+ songs to stress-test the “unlimited” claim:

Verdict: “Unlimited” is accurate for 99% of users. Unless you’re generating 50+ songs per day, you’ll never hit any practical limit.

How Does This Compare to “Unlimited” Competitors?

Let’s fact-check other platforms that claim “unlimited”:

• Suno Free: “50 credits per day” = ~10 songs/day = NOT unlimited
• Udio Free: “1,200 credits per month” = ~120 songs/month = NOT unlimited
• Mureka Free: ~120 songs/month = NOT unlimited
• FreeMusic.ai: 2 songs/month = Definitely NOT unlimited
• Sonauto/Treblo: No caps, no credits = ACTUALLY unlimited ✅

Can You Download Songs on the Free Plan?

Yes, Sonauto’s free plan includes unlimited downloads in all audio formats.

This is a massive differentiator. Let’s compare download capabilities:

What You Can Do with Sonauto Downloads

Download capabilities on free plan:

• ✅ Download any song you generate
• ✅ Re-download the same song multiple times
• ✅ Choose your preferred audio format each time
• ✅ Download individual stems (vocals, drums, bass, etc.)
• ✅ No watermarks on downloaded files
• ✅ Full quality (no compression or quality reduction)

Recommended Download Formats by Use Case

Can You Use the Free Plan Commercially?

⚠️ This is the critical question—and the answer is unclear.

Sonauto’s commercial licensing terms for the free tier are not clearly documented as of August 2026. This is the platform’s biggest weakness and a major concern for anyone planning commercial use.

What We Know (and Don’t Know)

How This Compares to Competitors

The Sonauto API: Clear Commercial Rights

If you need commercial licensing, Sonauto offers the Melodia API for $0.075 per generation, which includes explicit commercial rights.

API pricing breakdown:

• 100 songs: $7.50
• 500 songs: $37.50
• 1,000 songs: $75

This is still cheaper than Suno Pro ($8/month for 500 songs) or Udio Standard ($10/month for ~400 songs) if you’re generating high volumes with clear commercial needs.

Reddit User Experiences: What Are People Saying?

“Sonauto’s TOS explicitly says that you own any right, title, or interest that may exist in the music/audio you generate using the service… but then it also says ‘personal, non-commercial use.’ It’s contradictory and confusing.”

— Reddit user, r/sonauto, January 2026

“I emailed Sonauto support asking about commercial rights for the free tier. They responded saying ‘use the API for commercial projects.’ That’s as clear as I could get.”

— Reddit user, r/SunoAI, February 2026

Is Sonauto Worth Paying For?

Here’s the thing: You don’t need to pay for Sonauto—it’s 100% free.

But let’s address the real question: Should you use Sonauto, or pay for a competitor?

Choose Sonauto Free If…

Pay for Suno Pro ($8/month) If…

Pay for Udio Standard ($10/month) If…

Cost-Benefit Analysis

Sonauto Pricing vs Suno

Since Suno is Sonauto’s biggest competitor, let’s do a detailed head-to-head comparison:

Pricing Comparison

Feature-by-Feature Comparison

Quality Comparison: Sonauto vs Suno

We generated the same prompt in both platforms to compare output quality:

Test prompt: “An upbeat indie pop song about summer road trips, female vocals, acoustic guitar, 120 BPM, major key”

Overall winner: Suno v5.5 has slightly better quality, but Sonauto offers 95% of the quality at $0 vs. $8/month. For most users, Sonauto’s free quality is more than sufficient.

Watch: Direct comparison of Sonauto vs Suno showing real-world generation quality

When to Choose Suno Over Sonauto

Pay for Suno Pro ($8/month) instead of using Sonauto free if:

• ✅ You need explicit commercial rights (monetized YouTube, Spotify, client work)
• ✅ You want absolute best quality (Suno v5.5 is slightly better than Melodia v3)
• ✅ You need advanced editing (Suno Studio, precise BPM/key control)
• ✅ You want priority queue (10 concurrent generations vs. 4)
• ✅ You’re a professional musician releasing music commercially

Stick with Sonauto free if:

• ✅ Budget is $0 and you don’t want recurring costs
• ✅ You’re creating personal projects or non-monetized content
• ✅ You value unlimited volume over marginal quality differences
• ✅ You’re testing and learning AI music generation

Final Verdict

After 30 days of testing, generating 150+ songs, and comparing Sonauto to every major competitor, here’s our final verdict on Sonauto AI pricing and value in 2026:

Who Should Use Sonauto?

✅ Perfect for:

• Content creators (YouTube, TikTok, Instagram) making non-monetized content
• Hobbyists and experimenters exploring AI music
• Students and educators learning music production
• Podcasters needing background music
• Anyone on a $0 budget who needs unlimited generation

⚠️ Not recommended for:

• Professional musicians releasing music commercially (use Suno Pro or AIVA)
• Freelancers doing client work (licensing unclear)
• Monetized content creators (YouTube with AdSense, Twitch, etc.)
• Anyone needing guaranteed commercial rights

Is Sonauto Worth It?

For free? Absolutely. Sonauto offers unprecedented value at $0—unlimited music generation with advanced features that would cost $10-30/month on other platforms. The quality rivals paid tools, and the lack of credit limits removes all friction from the creative process.

The only caveat: Commercial licensing uncertainty. If you’re creating personal content, Sonauto is unbeatable. If you need commercial rights, budget $8/month for Suno Pro instead.

Our Recommendation

Bottom line: Sonauto is the most generous free AI music generator in 2026. While it lacks commercial licensing clarity, its unlimited generation and advanced features make it the best choice for personal use. For commercial needs, Suno Pro offers better licensing at $8/month.
