Depends on the use case. Suno wins on vocal quality and lyrical generation. Udio leans realistic vocals. Solmi is the only all-in-one (song + music video + AI covers + vocal removal). Riffusion is best for fast generation but lighter on features.
Suno and Udio have free tiers and ~$10/month paid plans. Solmi also has a free tier; its paid plans start at $35/month (Plus, 2,000 credits) because they include the full music-video pipeline — lip-synced performers, Suno import, and 720p/1080p rendering — not just audio.
Suno Premier, Udio Standard, and Solmi Pro all grant commercial use for monetized publishing. Read the specific terms — Suno Premier is the most permissive in 2026.
Yes — most creators in 2026 use 2–3 tools. Suno or Udio for the song, Solmi for the music video and any voice cover work. The tools are complementary, not directly competing.
