Stable Audio
Stable Audio is Stability AI's music and sound-effects generator, and the only major player offering open-weight music models trained on fully licensed data. The hosted app (running Stable Audio 2.5) has tiers from free to $89.99/mo, while the Stable Audio 3.0 Small and Medium models released in May 2026 are open weights on Hugging Face, free for commercial use under $1M revenue. That means you can self-host, own your outputs, and generate variable-length tracks up to six minutes. The hosted free tier is thin (10 generations, 30-second crop, non-commercial), but the open-weight option is genuinely unique.
Resemble AI
Resemble AI started as a voice-cloning and text-to-speech platform and has expanded into 'generative AI security' -- it generates voices, watermarks them, and detects deepfakes across audio, image, and video. Pricing is transparent pay-as-you-go (TTS around $0.0005/sec, ~$1.80/hr) with credits that never expire, plus custom enterprise. There's no ongoing free tier, just initial credits to start. It open-sourced its Chatterbox TTS model (popular on Hugging Face), and its real differentiator is provenance and deepfake defense, not the cheapest narration.
Stable Audio edges Resemble AI on aggregate — 85 vs 82.
The open-weight, own-your-output choice for music and SFX -- uniquely lets you self-host, but the hosted free tier is thin. Resemble AI still wins for buyers who prioritise transparent per-second pricing, credits never expire. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
