What each tool actually does — vocals, stems, loops, or scores
**Suno** is the platform most people mean when they say 'AI music generator.' You type a prompt or paste lyrics, pick a style, and it returns a full song with vocals in roughly 30 seconds. The Pro plan at $10/month (https://suno.com/pricing) gives 500 songs and commercial rights, which is the cheapest licensed path to vocal-driven AI music on the market. The hero feature is vocals: you can clone vocal style references, generate hooks, and iterate on lyrics in-product. The trade-off is that mastering is inconsistent and you do not get clean stems at the entry tier.
**Udio** is the closest direct competitor. Pricing matches Suno exactly at $10/month for Standard with 1,200 songs and $30/month for Pro with 4,800 songs (https://www.udio.com/pricing), and most engineers I trust prefer Udio's mastering and frequency response. Udio Pro also delivers cleaner stems for editing, which matters if you intend to drop the AI-generated track into a Logic or Ableton session. If you are choosing between the two on pure unit cost, Udio is roughly two and a half times cheaper per song at the entry paid tier — but Suno still wins on prompt fidelity for very specific genre callouts.
**Stable Audio** is Stability AI's diffusion-based model, and it is built for producers, not consumers. Pro at $11.99/month buys 500 generations, Studio at $24.99 buys 1,500, and Max at $89.99 buys 10,000 (https://stableaudio.com/pricing). The output is instrumental and built around loops, transitions, and stems — there is no vocal generation. If your job is to deliver a 16-bar instrumental hook to a producer who will then arrange it, Stable Audio's stem export and clean tail handling beat Suno and Udio. If you want a finished song with vocals, it is the wrong tool.
**Soundraw** is a different category entirely. Creator at $16.99/month and Artist at $39.99/month buy unlimited royalty-free downloads (https://soundraw.io/pricing), which means the per-track cost approaches zero at any reasonable usage. You do not generate songs from text prompts; you tune parameters like mood, length, and instrument and the system arranges variations. This is the right tool for YouTubers and agencies cranking out high volume background music where the per-track price needs to be effectively zero.
**AIVA** is the orchestral specialist. Standard at €15/month is explicitly non-commercial, and you need Pro at €49/month for 300 downloads and full ownership of the composition (https://www.aiva.ai/pricing). AIVA exports MIDI, which means film, game, and ad composers can take the generated stems into Cubase or Logic and finish the arrangement with real instruments. **Beatoven.ai** ($20/month Pro for 15 downloads, $99/month Premium for 75; https://www.beatoven.ai/pricing) is purpose-built for mood-based background, **Mubert** ($14 Creator, $39 Pro, $199 Business; https://mubert.com/render/pricing) is API-first for app integrations, and **ElevenLabs Music** is bundled into the broader Creator+ plans (https://elevenlabs.io/pricing) rather than sold as a separate product.
