Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
